Titan-Stealer: A New Golang-based Info-Stealer Malware


Recently, a new Golang-based information stealer malware, named ‘Titan Stealer’ is being promoted by threat actors in their Telegram channel. Initial details regarding the malware were discovered by cybersecurity researcher Will Thomas in November 2022 by using the IoT search engine Shodan. 

Titan is advertised as a malware builder that enables users to alter the malware binary's functionality and the type of data that will be extracted from a victim's system. 

The malware, when launched, initiates a technique called ‘process hollowing’ in order to disseminate the malicious payloads into the memory of a legitimate process called AppLaunch.exe, Microsoft’s .NET ClickOnce Launch Utility. 

According to a recent report by Uptycs security, researchers Karthickkumar Kathiresan and Shilpesh Trivedi say, “the stealer is capable of stealing a variety of information from infected Windows machines, including credential data from browsers and crypto wallets, FTP client details, screenshots, system information, and grabbed files.” 

Targets of The Info Stealer 

The Titan Stealer has been targeting web browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge, Yandex, Opera, Brave, Vivaldi, 7 Star Browser, Iridium Browser, and others. The crypto wallets singled out are Armory, Atomic, Bytecoin, Coinomi, Edge Wallet, Ethereum, Exodus, Guarda, Jaxx Liberty, and Zcash. 

Additionally, it has the ability to collect data from the Telegram desktop app and compile a list of the host's installed programs. 

The gathered information is then transmitted as a Base64-encoded archive file to a remote server under the attacker's control. Additionally, the malware includes a web panel that enables threat actors to access the stolen data. 

How is the Titan Stealer Operated? 

The exact approach used to distribute the malware is still unclear, but the threat actors have utilized numerous methods, such as phishing, malicious ads, and cracked software. 

"One of the primary reasons [threat actors] may be using Golang for their information stealer malware is because it allows them to easily create cross-platform malware that can run on multiple operating systems, such as Windows, Linux, and macOS," says Cyble in its analysis of Titan Stealer. "Additionally, the Go compiled binary files are small in size, making them more difficult to detect by security software." 

The findings come a little over two months after SEKOIA unveiled Aurora Stealer, another Go-based malware that is being used by a number of criminal actors in their campaigns. 

The malware often spreads through websites that mimic a renowned software, with the same domains being continuously updated to host trojanized versions of different programs. 

It is also found to be taking advantage of a tactic called padding in order to artificially inflate the size of the executables to as much as 260MB by adding random data, in order to evade detection by antivirus software. 

StrongPity Hackers Disseminate Trojanized Telegram App to Android Users

 

The StrongPity APT hacking group is disseminating a bogus Shagle chat app that is a trojanized version of the Telegram for Android app with a backdoor added. Shagle is a legitimate random video chat platform that allows strangers to communicate through an encrypted communications channel. 

However, the platform is entirely web-based and does not include a mobile app. Since 2021, StrongPity has been using a phony website that impersonates the official Shagle site to trick victims into downloading a malicious Android. Once installed, this app allows hackers to spy on their targets by monitoring phone calls, collecting SMS texts, and stealing contact lists.

StrongPity, also known as Promethium or APT-C-41, was previously linked to a malware-infecting campaign that distributed trojanized Notepad++ installers and malicious versions of WinRAR and TrueCrypt.

ESET researchers found the latest StrongPity activity and linked it to the espionage APT group based on code similarities with previous payloads. Furthermore, the Android app is signed with the same certificate that the APT used to sign an app in a 2021 campaign that mimicked the Syrian e-gov Android application.

Trojanizing the Telegram app 

StrongPity's malicious Android app is an APK file called "video.apk," which is a modified version of the standard Telegram v7.5.0 (February 2022) app.

ESET was unable to determine how victims arrived at the bogus Shagle website, but it is most likely through spear phishing emails, smishing (SMS phishing), or online instant messages. The malicious APK is downloaded directly from the bogus Shagle website and has never appeared on Google Play.

According to ESET, the cloned site first appeared online in November 2021, so the APK has most likely been actively distributed since then. The first confirmed detection in the wild, however, occurred in July 2022. One disadvantage of using Telegram as the basis for the hacking group's fake app is that the backdoored version will not be installed if the victim already has the real Telegram app installed on their phones.

The API ID used in the captured samples has currently been limited due to overuse, so the trojanized app will no longer approve new user registrations; thus, the backdoor will not function. This, according to ESET, indicates that StrongPity malware was successfully deployed on targeted victims.

Backdoor for spying on victims

When the malware is installed, it requests Accessibility Service access and then retrieves an AES-encrypted file from the attacker's command and control server. The file contains 11 binary modules that were downloaded to the device and used by the backdoor to perform various malicious functions.

Each module serves an espionage purpose and is activated as needed. The following is a complete list of the malicious spyware modules:
  • libarm.jar – records phone calls
  • libmpeg4.jar – collects text of incoming notification messages from 17 apps
  • local.jar – collects file list (file tree) on the device
  • phone.jar – misuses accessibility services to spy on messaging apps by exfiltrating contact name, chat message, and date
  • resources.jar – collects SMS messages stored on the device
  • services.jar – obtains device location
  • systemui.jar – collects device and system information
  • timer.jar – collects a list of installed apps
  • toolkit.jar – collects contact list
  • watchkit.jar – collects a list of device accounts
  • wearkit.jar – collects a list of call logs
The information gathered is saved in the app's directory, encrypted with AES, and then sent back to the attacker's command and control server.

The malware can read notification content from Messenger, Viber, Skype, WeChat, Snapchat, Tinder, Instagram, Twitter, Gmail, and other services by abusing the Accessibility Service. The malware automatically grants itself permission to change security settings, write to the filesystem, reboot, and perform other dangerous functions on rooted devices where the regular user has administrator privileges.

Since 2012, the StrongPity hacking group has been active, frequently hiding backdoors in legitimate software installers. According to ESET's report, the threat actor is still using the same tactic after a decade. Android users should exercise caution when downloading APKs from sources other than Google Play.

North Korean Lazarus Group Targeting Crypto Market via Telegram & Excel File


DEV-0139 uses targeted attacks to steal cryptocurrency investments 

Microsoft has identified a threat actor that has been targeting cryptocurrency investment startups. An entity that Microsoft has termed as DEV-0139 posed as a cryptocurrency investment firm on Telegram and used an Excel file deployed with malicious "well-crafted" malware to attack systems and access them remotely. 

The threat is part of a trend in cyberattacks showing a high degree of sophistication. In our case, the threat actor made a fake OKX employee profile and joined Telegram groups used for facilitating communication between VIP clients and cryptocurrency exchange platforms. 

In recent years, the cryptocurrency market has grown exponentially, getting the attention of investors as well as threat actors. Cybercriminals have used cryptocurrency for their attacks and campaigns, especially for ransom payment in ransomware attacks. 

DEV-0139 uses Telegram and Excel files to target victim

There has also been a rise in threat actors directly attacking organizations in the cryptocurrency industry for monetary motives. Cyberattacks targeting the cryptocurrency market come in various forms, this includes fraud, vulnerability exploitation, fake apps, and use of info stealers, threat actors use these variables to steal cryptocurrency funds. 

In October, the victim was asked to join a new group and then asked to provide feedback on an Excel document that compared Binance, OKX, and Huobi VIP fee structures. 

The document offered correct information and high awareness of the ground reality of crypto trading, however, it also sideloaded an infected. DLL (Dynamic Link Library) file to make a backdoor into the user's system. The victim was then told to view the .dll file while discussing the course fees. 

According to Microsoft, the weaponized Excel file initiates the following series of activities:

  • A malicious macro in the weaponized Excel file abuses the UserForm of VBA to obfuscate the code and retrieve some data.
  • The malicious macro drops another Excel sheet embedded in the form and executes it in invisible mode. The said Excel sheet is encoded in base64 and dropped into C:\ProgramData\Microsoft Media\ with the name VSDB688.tmp
  • The file VSDB688.tmp downloads a PNG file containing three executables: a legitimate Windows file named logagent.exe, a malicious version of the DLL wsock32.dll, and an XOR-encoded backdoor.
  • The file logagent.exe is used to sideload the malicious wsock32.dll, which acts as a DLL proxy to the legitimate wsock32.dll. The malicious DLL file is used to load and decrypt the XOR-encoded backdoor that lets the threat actor remotely access the infected system.

The attack method is popular, Microsoft suggests the attacker was the same as the one running .dll files for the same reasons in June, and also behind other cyberattack instances as well. As per Microsoft, DEV-0139 is the same threat actor that cybersecurity agency Volexity associated with North Korea's state-sponsored Lazarus Group. 

It uses a malware strain called AppleJeus and an MSI (Microsoft installer). The United States federal Cybersecurity and Infrastructure Security Agency reported on AppleJeus last year and Kaspersky Labs documented it in 2020. 

To stay safe from such threats, Microsoft suggests:

1. Use the included indicators of compromise to investigate whether they exist in your environment and assess for potential intrusion.

2. Educate end users about protecting personal and business information in social media, filtering unsolicited communication (in this case, Telegram chat groups), identifying lures in spear-phishing emails and watering holes, and reporting reconnaissance attempts and other suspicious activity.

3. Educate end users about preventing malware infections, such as ignoring or deleting unsolicited and unexpected emails or attachments sent via instant messaging applications or social networks. Encourage end users to practice good credential hygiene and make sure the Microsoft Defender Firewall (which is enabled by default) is always on to prevent malware infection and stifle propagation.

4. Change Excel macro security settings to control which macros run and under what circumstances when you open a workbook. Customers can also stop malicious XLM or VBA macros by ensuring runtime macro scanning by Antimalware Scan Interface (AMSI) is on. This feature—enabled by default—is on if the Group Policy setting for Macro Run Time Scan Scope is set to “Enable for All Files” or “Enable for Low Trust Files”.

5. Turn on attack surface reduction rules to prevent common attack techniques observed in this threat:

  • Block Office applications from creating executable content
  • Block Office communication application from creating child processes
  • Block Win32 API calls from Office macros
6. Ensure that Microsoft Defender Antivirus is up to date and that real-time behavior monitoring is enabled.

The cryptocurrency market is a lucrative interest for cybercriminals. Targeted victims are identified via trusted channels to better the chance of attack. While hackers prefer targeting big organizations, smaller organizations can also become an easy target of interest. 






A Copyright Violation Lawsuit Involves Telegram Sharing Users' Data

 


Following a court order in India, Telegram has disclosed the names, contact information, and IP addresses of administrators of channels accused of copyright infringement. The fact that it can provide authorities with such a large volume of data about its users in just a few seconds demonstrates the power of the instant messaging platform in terms of what it can get. 

An order by the Delhi High Court compelled the app owner to share the data imposed on him by the court. An argument was made that the company had not taken enough steps to prevent the unauthorized distribution of a teacher's course material on the platform. This was after she filed a lawsuit against the company. Neetu Singh, the teacher who was the plaintiff in the case, told several Telegram channels were reselling her study materials. However, they were not allowed to do so. 

Telegram had earlier been ordered by an Indian court to follow Indian law and disclose information about the members who operate such channels. 

During its litigation, Telegram tried unsuccessfully to argue that disclosing information about users would violate its privacy policies and the laws of Singapore. Telegram is currently maintaining its physical servers for storing the data of its users in Singapore. The court dismissed this argument as the ongoing infringement activity is connected to Indian works. This activity is likely to be attributed to Indian users. However, even if the data is stored in places other than India, it could still be accessed from there. 

Earlier this week, Justice Pratibha Singh told Telegram's board members that Telegram had complied with the earlier order and had shared the data with them. 

As part of the case, a copy of the said data will be provided to counsel for the plaintiffs. This will be with a clear warning that neither they nor any of their representatives shall share this data with a third party. However, for the present proceedings, such disclosure is not permitted. A report first put forth by LiveLaw from the court (PDF) states that disclosure of information to the police/government authorities is permissible. 

Telegram spokesperson Remi Vaughn commented that there was no response from Telegram regarding whether private information was shared. He added, generally, Telegram does not store very much information about its users. Our understanding is that, in many cases, we will not be able to access any user data without a specific entry point. This may have been the case here. Due to this, Telegram cannot confirm that there has been any sharing of private information in this instance.

Interestingly, Telegram has grown to rank among the top five most used apps in the South Asian region. This is because Telegram has nearly 150 million users across the continent. According to a previous report, Telegram's piracy problem might have contributed to the sudden popularity of the app among some users. Movies and TV shows are widely shared on the platform. These movies and TV shows will remain littered with easily discoverable channels, some of which have tens of thousands of users - where users can discover or find easily discoverable content.

Pavel Durov: Users Must Cease Using WhatsApp Since it's a Spying Tool

WhatsApp is among the most popular messaging apps in the world. It was first launched in January 2009 and since then evolved to include audio and video calls, emojis, and WhatsApp Payments. However, criticism has also surrounded the well-known messaging app due to claims about privacy and security issues. 

Recently, WhatsApp disclosed a security flaw affecting its Android app that was deemed critical. Pavel Durov, the creator of Telegram, pokes fun at WhatsApp and advises users to avoid it. 

Hackers could have complete access to all aspects of WhatsApp users' phones, according to Telegram founder Pavel Durov. Additionally, he asserted that WhatsApp has been monitoring user data for the past 13 years while claiming that WhatsApp's security flaws were planned purposely.

Durov outlined Telegram's security and privacy characteristics by saying, "I'm not trying to convince anyone to use Telegram here. There is no need to promote Telegram more." He claimed that Telegram's instant messaging software prioritizes privacy. With more than 700 million active users as of right now, the app is apparently growing steadily, adding over 2 million new users every day.

Regarding security and privacy, WhatsApp states that all texts, chats, and video calls are provided with end-to-end encryption. However, the program has frequently experienced bugs and security problems, which have sparked concerns about its privacy.

In terms of private chats and user data, WhatsApp already has a complicated and distorted past. People have been worried about Facebook's handling of users' personal data ever since it purchased Meta in 2014. For revealing user data not just with governmental organizations but also with private parties, Meta has been criticized for a considerable time.

The rise in popularity of Telegram and Signal and other instant messaging services with a security and privacy focus can be attributed to this.

According to a recent report from Meta, WhatsApp users are susceptible to hacking due to a flaw in the way videos are downloaded and played back. If this flaw is exploited, hackers would have complete access to virtually everything on the phone of the WhatsApp user. Along with users' emails and pictures, this also contains other correspondence, such as SMS messages from various banks and app data from one's banking and payment apps.




Evolution of LilithBot Malware and Eternity Threat Group

A variant of the versatile malware LilithBot was recently uncovered by ThreatLabz in its database. This was connected to the Eternity group, also known as the Eternity Project, a threat entity affiliated with the Russian Jester Group, which has been operating since at least January 2022, according to further investigation.

In the darknet, Eternity disseminates many malware modules bearing the Eternity name, such as a stealer, miner, botnet, ransomware, worm+dropper, and DDoS bot.

LilithBot Malware

The distribution channels for the LilithBot that were found were a specialized Telegram group and a Tor connection that offered one-stop shopping for these multiple payloads. It included built-in stealer, clipper, and miner capabilities in addition to its primary botnet activity. 

The LilithBot multipurpose malware bot was discovered by Zscaler's ThreatLabz threat research team in July 2022 and was being offered as a subscription by the Eternity organization. In this campaign, the threat actor adds the user to its botnet and then steals files and user data by sending it via the Tor network to a command-and-control (C2) server. The malware in this campaign performs the functions of a stealer, miner, clipper, and botnet while using false certificates to avoid detection.

This malware-as-a-service (MaaS) is unusual because, in addition to using a Telegram channel to share updates on the latest features, it also uses a Telegram Bot to let customers create the binary. Common cryptocurrencies accepted by Eternity for payments include BTC, ETH, XMR, USDT, LTC, DASH, ZEC, and DOGE. Eternity often conducts business via Telegram.

If the buyer requests it, hackers will construct viruses with add-on functionality and offer customized viruses. The infection costs from $90 and $470 in USD. The Eternity Telegram channel demonstrates the frequent upgrades and improvements the team makes to its services.

The Eternity gang frequently refers users to a dedicated Tor link where a detailed description of their various viruses and their features may be found. The Tor link takes you to the homepage, where you can learn more about the different products and modules you may buy. The targeted user's files and documents are encrypted by the malware. A specific video explaining how to create the ransomware payload is available on the Tor page. Their Ransomware is the most expensive item on sale. For yearly membership, Eternity Stealer costs $260.
  • Eternity Miner as a yearly subscription costs $90.
  • Eternity Miner ($90 )as an annual subscription 
  • Eternity Clipper ($110 )
  • Eternity Ransomware ($490)
  • Eternity Worm ($390)
  • Eternity DDoS Bot (N/A) 

It is adaptable to the unique needs of clients and can constantly be updated at no further cost. They also provide their clients with numerous additional discounts and perks.

It is possible that the organization is still carrying out these tasks as the LilithBot malware has developed, but doing so in more complex ways, for as by completing them dynamically, encrypting the tasks like other areas of code, or employing other cutting-edge strategies.

The 'Microsoft Code Signing PCA' certificate authority issues a valid Microsoft-signed file, and it will also show a countersignature from Verisign. But as research is seen, LilithBot's bogus certificates lack a countersignature and appear to have been granted by the unverified Microsoft Code Signing PCA 2011.

Void Balaur Targets Russian Entities

A hacker-for-hire company that was originally revealed in 2019 has extended its scope to target victims with links to Russia in the political and corporate sector. 

Reported to attack a variety of known target groups worldwide, Void Balaur is a very active hacker-for-hire cyber mercenary gang. Since at least 2016, people have seen their services available for purchase online. Private data collection and access to particular online email and social media sites, including Gmail, Outlook, Telegram, Yandex, Facebook, Instagram, and corporate emails, are among the services offered. 

Google claims Since 2012, TAG has been keeping tabs on a diverse group of Indian hackers-for-hire, many of whom have worked briefly for Indian security companies Appin and Belltrox.

The gang often conducts attacks that are both general and opportunistic with the goal of getting illegal access to popular email services, social networks, communications, and corporate accounts.

According to reports, the hack-for-hire service provided by the gang is offered using a variety of guises, including Hacknet and RocketHack. The operators have offered additional services over the years, including real-time location tracking, SMS logs, and remote device access.

Furthermore, the assault infrastructure run by Void Balaur includes more than 5,000 distinct domains that present themselves as portals for public services, authentication services, and email websites.

A wide range of industries, frequently with specific political or business ties to Russia, are among the new targets. Additionally, Void Balaur hunts out targets useful for positioning or assisting upcoming assaults. They have the United States, Russia, Ukraine, and a number of other nations as their targets.

However, in early 2022, one of the group's managed domains resolved to an IP address that belongs to and is run by the Russian Federal Guard Service (FSO), indicating what appears to be an operating oversight and raising the possibility of a connection.

Despite the fact that Void Balaur targets persons and organizations all over the world, ads launched in 2022 have targeted individuals who are active in political and business circumstances that are important to Russia.

The use of highly repeatable phishing emails that look like they are from banks or local governments is common in order to deceive recipients into clicking a malicious link and divulging their account information.

In September 2021, one of the group's most infamous efforts featured attacks that targeted the personal email accounts of lawmakers and government leaders of an Eastern European nation.

In accordance with its reputation as a cyber mercenary, Void Balaur does not confine itself to the geopolitical sphere. Nonetheless,  employing and adopting the proper security measures will help in repelling cyber mercenary attacks.

Killnet Targets Japanese Government Websites

According to investigation sources on Wednesday, the Tokyo Metropolitan Police Department intends to look into the recent website outages of the Japanese government and other websites that may have been brought on by cyberattacks by a Russian hacker organization.  

As per Chief Cabinet Secretary Hirokazu Matsuno, the government is apparently investigating if issues with the aforementioned sites were brought on by a denial-of-service (DDoS) attack. 

As per experts, access to the government's e-Gov portal website, which provides a wealth of administrative information, temporarily proved challenging on Tuesday.  

The pro-Russian hacker collective Killnet claimed responsibility for the attack and alleged it had attacked the electronic system of the tax authority and Japan's online public services in a post on the messaging app Telegram. Furthermore, it appeared that the hacker collective wrote that it was an uprising over Japan's 'militarism' and that it kicked the samurai. 
 
However, as per Sergey Shykevich, manager of Check Point Software's threat intelligence group, Killnet was likely responsible for these attacks.  

Killnet's justification for these strikes, according to Shykevich, "is owing to Japan's support of Ukraine in the ongoing Russia-Ukraine war, as well as a decades-long dispute over the Kuril Islands, which both sides claim control over."

As per the sources, the MPD will look into the cases by gathering specific data from the affected businesses and government bodies. The National Police Agency will assess whether the hack on the e-Gov website qualified as a disruption that materially impairs the operation of the government's primary information system as defined by the police statute, which was updated in April.

The cybersecurity expert added that firms in nations under attack by Killnet should be aware of the risks because the group employs a variety of tactics, such as data theft and disruptive attacks, to achieve its objectives. 

Following a recent large-scale attack by Killnet on websites in Italy, Lithuania, Estonia, Poland, and Norway, there have been allegations of attacks targeting Japanese government websites.





The Prynt Stealer Malware Includes a Secret Backdoor, Hackers Steal Data from Credentials


Telegram channel used for attacks

Zscaler experts have found a Telegram channel-based backdoor in the info-stealing malware, which lets threat actors steal (secretly) a copy of the information extracted from the targets, it includes a secret backdoor in the code that gets in every variant and derivative copies of these malware strains. 

The backdoor sends copies of victims' stolen data gathered by other hackers to a private telegram chat monitored by the builder's developers. 

The unfortunate surprise isn't a novelty in the cybercrime landscape, earlier other malware were found to have a secret backdoor. 

What is Prynt Stealer?

Prynt Stealer is an info stealer that was found in April, it lets its operators extract credentials from web browsers, FTP/VPN clients, and messaging and gaming apps. 

The malware is based on open-source projects, this includes AsynRAT and StormKitty, and it extracts data stolen from victims via a Telegram channel. 

Prynt Stealer can be purchased in the underground market for $100 for a one-month licence and a lifetime subscription worth $900. 

How does the attack work?

Prynt Stealer has a code that is responsible for sending information to Telegram from StormKitty with a few trivial changes. Experts add that the info stealer avoids using anti-analysis code from either StormKitty or AsyncRAT. 

It makes a thread that activates the function called processChecker to constantly monitor the target's process list for activities like taskmgr, netstat, netmon, and wireshark. 

If any monitored processes are found, it bans the Telegram C2 (Command and Control) communication channels. 

Zscaler report says:

"The fact that all Prynt Stealer samples encountered by ThreatLabz had the same embedded telegram channel implies that this backdoor channel was deliberately planted by the author. Interestingly, the Prynt Stealer author is not only charging some clients for the malware, but also receiving all of the data that is stolen." 

Leaked copies used for attack

"Note that there are cracked/leaked copies of Prynt Stealer with the same backdoor, which in turn will benefit the malware author even without direct compensation.”

The experts also noticed leaked/cracked copies of Prynt Stealer that contained the same backdoor, which suggests that the malware author was able to get stolen data from these copies. 

Experts also found two more versions of the info-stealing malware named WorldWind and DarkEye that were written by the same author. 

What is DarkEye?

The experts observed that DarkEye is not mentioned or sold openly, but it is wrapped as a backdoor with a "free" Prynt Stealer builder. Threat actors use the backdoor with LodaRat and DarkEye stealer. 

The report concludes: 

"the free availability of source code for numerous malware families has made development easier than ever for less sophisticated threat actors. As a result, there have been many new malware families created over the years that are based on popular open-source malware projects like NjRat, AsyncRAT, and QuasarRAT. The Prynt Stealer author went a step further and added a backdoor to steal from their customers by hardcoding a Telegram token and chat ID into the malware.”



Cloudflare Users Targeted by Hackers that Breached into Twilio


On Tuesday, the web infrastructure provider Cloudflare revealed that at least 76 of its staff members and their families had received texts on both personal and business phones that resembled the intricate phishing effort on Twilio.

Furthermore, Cloudflare said that its Cloudforce One threat intelligence team was able to do an analysis of the attack, despite the fact that its systems were not hacked.

The systems and officials of several firms are the targets of this sophisticated attack, as per analysts. Four phone numbers linked to SIM cards issued by T-Mobile were used in the attack, which exists around the same time Twilio was targeted and was ultimately unsuccessful.

Cloudflare said the rogue domain was built via Porkbun under 40 minutes before the wave of more than 100 smishing messages started. It also said the phishing page was created to quickly pass the data given by unwary customers to the attacker via Telegram.

The data was directly taken to the attacker via the messaging app Telegram once the message receiver input his credentials on the phishing site. Experts claim since the phishing page would request a Time-based One Time Password (TOTP) code, the real-time relay was essential for the hackers. Once they had this information, the attackers would access the actual login page for the victim company.

Only three employees, as per Cloudflare, clicked the link in the phishing email and submitted their credentials. However, the business does not use TOTP codes; rather, its staff members use a YubiKey security key that complies with FIDO2. This implies that even if an attacker has the credentials, they cannot access the firm systems without the hardware key.

As Cloudflare also disclosed, AnyDesk remote access software was immediately downloaded on their machines after providing their credentials on the phishing pages, enabling the hackers to remotely take control of their systems if installed.

The company stated it reset the affected employees' login passwords and tightened its access policy to block any logins from unidentified VPNs, residential proxies, and infrastructure providers in addition to working with DigitalOcean to shut down the attacker's server.



Data Spyware Delivered via Telegram & Discord Bots

Hackers have utilized these messaging apps in a variety of ways to transmit their own malware, according to Intel 471's research. They have discovered ways to host, distribute, and execute various activities on these platforms, which they mostly exploit in cooperation with data theft in order to be able to steal credentials or other information from unwary users.

According to a recent study from Intel 471, threat actors are using the multifaceted nature of messaging apps — in particular, their content-creation and program-sharing components — as a basis for information stealing.

Tactics & Techniques

Researchers at Intel 471 have found a number of data thefts that are openly accessible and depend on Telegram or Discord to operate.

Additionally, these hackers conduct similar attacks against the Roblox and Minecraft gaming sites. Discord's content delivery network (CDN) is regularly used to store malware, as per researchers, because the platform doesn't place limitations on file storage.

One Telegram-focused botnet, dubbed X-Files, includes features that may be accessible through Telegram's bot commands. Once the malware has been installed on a victim's computer, criminal actors can take credit card information, login credentials, session cookies, and passwords, and send them to a Telegram channel of their choice. 

Several browsers, including Google Chrome, Chromium, Opera, Slimjet, and Vivaldi, may import data into X-Files. Although Prynt Stealer, another stealer, operates similarly, it lacks the built-in Telegram commands.

The following malware families have been seen hosting harmful payloads on Discord CDN: PrivateLoader,  Discoloader, Colibri, Warszone RAT, Modi loader, Raccoon thief, Smokeloader Amadey,  Tesla agent thief, GuLoader, Autohotkey, and njRAT.

Cautions

The entry threat for malicious actors is reduced by automation in well-known chat platforms. Data theft might be the initial step in initiating a targeted attack against an enterprise, even though they can not alone cause as much harm as malware like a data wiper or ransomware.

Although messaging services like Discord and Telegram are not often utilized for corporate activities, their popularity and the surge in remote work have increased the attack surface available to cybercriminals.




XFiles Malware Exploits Follina, Expands ItsAttacks

What is XFiles?

The X-Files info stealer malware has put a new vulnerability in its systems to exploit CVE-2022-30190- Follina, and attack targeted systems with malicious payloads. A cybersecurity firm said that the new malware uses Follina to deploy the payload, run it, and take control of the targeted computer. "In the case of the XFiles malware, researchers at Cyberint noticed that recent campaigns delivering the malware use Follina to download the payload, execute it, and also create persistence on the target machine," says Bleeping Computers.  

How is Follina infected? 

•The malware, sent in the victims' spam mail, consists of an OLE object that directs to an HTML file on an external resource that has JavaScript code, which exploits Follina. 

•After the code is executed, it gets a base64-encoded string that contains PowerShell commands to make a presence in the Windows startup directory and deploy the malware. 

•The second-stage module, "ChimLacUpdate.exe," consists of an AES decryption key and a hard-coded encryption shellcode. An API call decodes it and deploys it in the same running process. 

•After infection, XFiles starts normal info stealer malware activities like targeting passwords and history stored in web browsers, cookies, taking screenshots, and cryptocurrency wallets, and look for Telegram and Discord credentials. 

•The files are locally stored in new directories before they are exfiltrated via Telegram. 

The XFiles is becoming more active 

• A cybersecurity agency said that XFiles has expanded by taking in new members and initiating new projects. 

• A project launched earlier this year by Xfiles is called the 'Punisher Miner.' 

• However, it's an irony that a new mining tool will charge $9, the same as how much XFiles costs for a month of renting the info stealer. 

CyWare Social says "it appears that the XFiles gang is expanding and becoming more prolific. The gang is recruiting talented malware authors, becoming stronger, and thus providing their users with more readymade tools that do not require experience or coding knowledge. Successful incorporation of the Follina-exploiting document increases the chances of infection and consequently increases the success rate of attacks."

Telegram is Selling the Eternity Malware Kit, Which Offers Malicious Services 

 

Cybercriminals have recently used Telegram to offer malware and other dangerous tools as services. Researchers have discovered a deadly new malware subscription plan which can be used to facilitate a wide range of attacks. 

The "Eternity Project," a modular malware kit, has capabilities that allow buyers to steal passwords and credit card information, launch ransomware attacks and infiltrate victims with cryptomining software. Each component of the malware toolkit, such as an information stealer, a coin miner, a clipper, ransomware software, a worm spreader, and, finally, a DDoS (distributed denial of service) bot, can be purchased separately. 

The creators share the latest update, usage instructions, and debate feature proposals on a private Telegram channel with over 500 members. Buyers can apparently use the Telegram Bot to assemble the binary automatically after choosing its desired feature set and paying the equivalent amount in cryptocurrency. The malware module is the most premium at $490 per year. The info-stealer, which costs $260 per year, steals passwords, credit cards, bookmarks, tokens, cookies, and autofill data from over twenty different web browsers. 

The malware's versatility is also highlighted through a deep-dive investigation of the infostealer module. Researchers claim that this single tool may gather data from a wide range of apps, including web browsers and cryptocurrency wallets, as well as VPN clients, messaging apps, and more. 

The miner module is $90 a year and includes features such as task manager invisibility, auto-restart once killed, and startup launch persistence. The clipper is a $110 application that scans the clipboard for cryptocurrency wallet credentials and replaces them with wallets controlled by the user. The Eternity Worm is available for $390 from the developer, and it can propagate itself using USB drivers, lan shares, local files, cloud drives, Python projects, Discord accounts, and Telegram accounts.

The authors say it's FUD (completely undetectable), a claim supported by Virus Total data showing zero detections for the strain. Surprisingly, the ransomware module provides an option of setting a timer that, when reached, renders the files entirely unrecoverable. This adds to the victim's pressure to pay the ransom as soon as possible. 

Despite the wide range of hazards posed by Eternity Project malware, Cyble says there are a few precautions consumers can take. Maintaining regular data backups, keeping software up to date, and avoiding visiting untrustworthy websites and email attachments are recommended best practices.

21M Users' Personal Data Exposed on Telegram

 

A database containing the personal information and login passwords of 21 million individuals was exposed on a Telegram channel on May 7th, 2022, as per Hackread.com. The data of VPN customers was also exposed in the breach, including prominent VPNs like SuperVPN, GeckoVPN, and ChatVPN. 

The database was previously accessible for sale on the Dark Web last year, but it is now available for free on Telegram. The hacked documents contained 10GB of data and exposed 21 million unique records, according to VPNMentor analysts. The following details were included: 
  • Full names
  • Usernames
  • Country names
  • Billing details
  • Email addresses
  • Randomly generated password strings
  • Premium status and validity period
Further investigation revealed that the leaked passwords were all impossible to crack because they were all random, hashed, or salted without collision. Gmail accounts made up the majority of the email addresses (99.5 percent). 

However, vpnMentor researchers believe that the released data is merely a portion of the whole dump. For the time being, it's unknown whether the information was gained from a data breach or a malfunctioning server. In any case, the harm has been done, and users are now vulnerable to scams and prying eyes. The main reason people use VPNs is to maintain their anonymity and privacy. Because VPN customers' data is regarded more valuable, disclosing it has far-reaching effects. 

People whose information was exposed in this incident may be subjected to blackmail, phishing scams, or identity theft. Because of the exposure of personally identifiable information such as country names, billing information, usernames, and so on, they may launch targeted frauds. Threat actors can easily hijack their accounts and exploit their premium status after cracking their credentials. 

If the data falls into the hands of a despotic government that prohibits VPN use, VPN users may be arrested and detained. Users should change their VPN account password and use a mix of upper-lower case letters, symbols, numbers, and other characters for maximum account security.

US has Offered a $10 Million Bounty on Data About Russian Sandworm Hackers

 

The United States announced a reward of up to $10 million for information on six Russian military intelligence service hackers. According to the State Department's Rewards for Justice Program, "these people engaged in hostile cyber actions on behalf of the Russian government against U.S. vital infrastructure in violation of the Computer Fraud and Abuse Act."

The US Department of State has issued a request for information on six Russian officers (also known as Voodoo Bear or Iron Viking) from the Main Intelligence Directorate of the General Staff of the Russian Federation's Armed Forces (GRU) regarding their alleged involvement in malicious cyberattacks against critical infrastructure in the United States. The linkages attributed are as follows : 

  • Artem Valeryevich Ochichenko has been linked to technical reconnaissance and spear-phishing efforts aimed at gaining illegal access to critical infrastructure sites' IT networks around the world. 
  • Petr Nikolayevich Pliskin, Sergey Vladimirovich Detistov, Pavel Valeryevich Frolov, and Yuriy Sergeyevich Andrienko, are accused of developing components of the NotPetya and Olympic Destroyer malware used by the Russian government to infect computer systems on June 27, 2017, and Yuriy Sergeyevich Andrienko, who are accused of developing components of the NotPetya and Olympic De.
  • Anatoliy Sergeyevich Kovalev is accused of inventing spear-phishing techniques and communications which were utilized by the Russian government to hack into critical infrastructure computer systems. 

On October 15, 2020, the US Justice Department charged the mentioned officials with conspiracy to commit wire fraud and aggravated identity theft for carrying out damaging malware assaults to disrupt and destabilize other countries and cause monetary damages. 

According to the indictment, GRU officers were involved in attacks on Ukraine, including the BlackEnergy and Industroyer malware-based attacks on the country's power grid in 2015 and 2016. The folks are accused of causing damage to protected computers, conspiring to commit computer fraud and abuse, wire fraud, conspiracy to commit wire fraud, and aggravated identity theft by the US Department of Justice. According to the US Department of State, the APT group's cyber actions resulted in roughly $1 billion in losses for US firms.

The Rewards of Justice has established a Tor website at "he5dybnt7sr6cm32xt77pazmtm65flqy6irivtflruqfc5ep7eiodiad[.]onion" as part of the project, which may be used to anonymously submit reports on these threat actors or to communicate the information using Signal, Telegram, or WhatsApp. 

Recently, the Sandworm collective was linked to Cyclops Blink, a sophisticated botnet malware that snagged internet-connected firewall devices and routers from WatchGuard and ASUS. Other recent hacking efforts linked to the gang include the use of an improved version of the Industroyer virus against high-voltage electrical substations in Ukraine amid Russia's continuing invasion.

T-Mobile Reveals its Security Systems were Hacked via Lapsus$ Hackers

 

T-Mobile acknowledged on Friday it had been the subject of a security compromise in March when the LAPSUS$ mercenary group gained access to its networks. The admission occurred after investigative journalist Brian Krebs published internal chats from LAPSUS$'s key members, revealing the group had infiltrated the company many times in March previous to the arrest of its seven members. 

After analyzing hacked Telegram chat conversations between Lapsus$ gang members, independent investigative journalist Brian Krebs first exposed the incident. T-Mobile said in a statement the breach happened "a few weeks ago" so the "bad actor" accessed internal networks using stolen credentials. "There was no customer or government information or any similarly sensitive information on the systems accessed, and the company has no evidence of the intruder being able to get anything of value," he added.

The initial VPN credentials were allegedly obtained from illegal websites such as Russian Market in order to get control of T-Mobile staff accounts, enabling the threat actor to conduct SIM switching assaults at anytime. 

The conversations suggest how LAPSUS$ had hacked T-Slack Mobile's and Bitbucket accounts, enabling the latter to obtain over 30,000 source code repositories, in addition to getting key to an internal customer account management application called Atlas. In the short time since it first appeared on the threat scene, LAPSUS$ has been known for hacking Impresa, NVIDIA, Samsung, Vodafone, Ubisoft, Microsoft, Okta, and Globant. 

T-Mobile has acknowledged six previous data breaches since 2018, including one in which hackers gained access to data linked to 3% of its members. T-Mobile acknowledged it had disclosed prepaid customers' data a year later, in 2019, and unknown threat actors had acquired access to T-Mobile workers' email accounts in March 2020. Hackers also acquired access to consumer private network information in December 2020, and attackers accessed an internal T-Mobile application without authorization in February 2021. 

According to a VICE investigation, T-Mobile, unsuccessfully, tried to prevent the stolen data from being posted online after paying the hackers $270,000 through a third-party firm in the aftermath of the August 2021 breach. After its stolen sensitive information turned up for sale on the dark web, the New York State Office of the Attorney General (NY OAG) alerted victims of T-August Mobile's data breach would face elevated identity theft risks. 

The City of London Police announced earlier this month as two of the seven adolescents arrested last month for alleged potential connections to the LAPSUS$ data extortion group, a 16-year-old, and a 17-year-old had been charged.

Anonymous Rises Again Amid Russia Ukraine War

 

Anonymous, the international hacktivists collective has surfaced again, this time, the group claims to have hacked RoskoAmnadzor (known as Federal Service for Supervision of Communications, Information Technology and Mass Media), a federal Russian agency. Anonymous has also claimed that it stole more than 360,000 files. You have mostly read about Russian banning VPNs, Telegram, or email services, however, there's a particular agency that bans these services. 

It's called Roskomnadzor, a major federal executive agency that is responsible for handling, managing, and censoring Russian media. "Anonymous also targeted and hacked misconfigured/exposed Cloud databases of Russian organizations. Tho shocking aspect of the attack was the fact that Anonymous and its affiliate hackers hacked 90% of Russian Cloud databases and left anti-war and pro Ukrainian messages," Hackread reports. 

Details about the attack 

The size of the leaked data is 820 GB, most of these database files in the database related to Roskomnadzor's data are linked to the Republic of Bashkortostan, Russia's largest provinces. The full dataset is now available on the official website of Distributed Denial of Secrets (aka DDoSecrets), a non for profit whistleblower organization. However, it should be noted that initially started as an Anonymous affiliate shared Roskomnadzor's data with DDoSecrets and the agency itself is not responsible for the attack. Besides this, the first announcement of the data leak came from a journalist and co-founder of DDoSecrets Emma Best in March 2022. 

YourAnonNews, a famous representative of the Anonymous collective also tweeted about the attack. Anonymous has openly sided with Ukraine over the ongoing war with Russia, the Russian government has restricted all important sources of information, especially news and media outlets, and Roskomnadzor was told to block Facebook, Twitter, and other online platforms. 

Hackread reports, "While Twitter launched its Tor onion service, authorities in Russia have also amended the Criminal Code to arrest anyone who posts information that contradicts the government’s stance. Nevertheless, since Roskomnadzor is a major government agency responsible for implementing government orders Anonymous believes the Russian public must have access to information about what is going on within Roskomnadzor."

Telegram Abused By Raccoon Stealer

 

As per a post released by Avast Threat Labs this week, Raccoon Stealer, which was first identified in April 2019, has added the capacity to keep and update its own genuine C2 addresses on Telegram's infrastructure. According to researchers, this provides them with a "convenient and trustworthy" command center on the network which they can alter on the fly. 

The malware, which is thought to have been built and maintained by Russian-linked cybercriminals, is primarily a credential stealer, but it is also capable of a variety of other nefarious activities. Based on commands from its C2, it can collect not just passwords but also cookies, saved logins and input data from browsers, login credentials from email services and messengers, crypto wallet files, data from browser plug-ins and extensions, and arbitrary files. 

As per the reports, Buer Loader and GCleaner were used to distribute Raccoon. Experts suspect it is also being distributed in the guise of false game cheats, patches for cracked software (including Fortnite, Valorant, and NBA2K22 hacks and mods), or other applications, based on some samples. 

Given since Raccoon Stealer is for sale, the only limit to its distribution methods is the imagination of the end-users. Some samples are spread unpacked, while others are protected by malware packers like Themida. It is worth mentioning whether certain samples were packed by the same packer five times in a row.

Within Telegram, the newest version of Raccoon Stealer talks with C2: According to the post, there are four "crucial" parameters for its C2 communication which are hardcoded in every Raccoon Stealer sample. Details are as follows:
  • MAIN KEY, which has changed four times throughout the year;
  • Telegram gate URLs with channel names; 
  • BotID, a hexadecimal string that is always sent to the C2; 
  • TELEGRAM KEY, a decryption key for the Telegram Gate C2 address. 

The malware decrypts MAIN KEY, which it uses to decrypt Telegram gates URLs and BotID, before hijacking Telegram for its C2. According to Martyanov, the stealer then utilizes the Telegram gate to connect to its real C2 via a series of inquiries to eventually allow it to save and change actual C2 addresses utilizing the Telegram infrastructure. 

The stealer can also transmit malware by downloading and executing arbitrary files in response to an instruction from C2. Raccoon Stealer spread roughly 185 files totaling 265 megabytes, including downloaders, clipboard crypto stealers, and the WhiteBlackCrypt ransomware, according to Avast Threat Labs.

Telegram has Experienced a Global Outage

 

On Thursday, March 3, the popular messenger Telegram experienced a failure. Users reported about the problems on the website of the service Downdetector, which tracks problems with access to Internet resources. 

According to Downdetector, the failure occurred at about 14 o'clock Moscow time. The majority of those who left complaints (56 percent) reported problems with the server connection. Users also noted problems with receiving messages (22 percent) and the operation of the application (23 percent). 

The failure affected residents of Russian cities, including Moscow and St. Petersburg. Users from Ukraine and Belarus also complained about the problems. 

The other day Pavel Durov published the following statement: "We do not want Telegram to be used as a tool to exacerbate conflicts and incite interethnic discord. In the event of an escalation of the situation, we will consider the possibility of partially or completely restricting the operation of Telegram channels in the countries involved during the conflict." 

According to him, recently Telegram has been increasingly used to spread fakes and unverified data related to the war, and the administration does not have the opportunity to check all publications for authenticity. However, soon Durov promised not to limit the work of the messenger in Ukraine. 

According to him, "a lot of users have asked us not to consider disabling Telegram channels for the period of the conflict, since we are the only source of information for them." But he urges users to "double-check and not take for granted the data that is published in Telegram channels during this difficult period." 

It is worth noting that in the week since the beginning of Russia's military operation in Ukraine, news channels in the Telegram messenger have added 19.5 million new subscribers. Another Russian social network, created at the time by Pavel Durov, is experiencing a new surge in popularity due to technical problems of other social networks. In VK, views in the news feed increased by 5% over the week, and the average daily number of video views increased by 15%. People are looking on platforms for up-to-date information from media that are subject to hacker attacks, and from eyewitnesses of events. 

Earlier, CySecurity News reported that three popular foreign social networks - Facebook, Instagram and Twitter began to receive complaints from residents of Russia in large numbers.

Facebook, Instagram and Twitter Users from Russia have Noticed Malfunctions in their Work

 

According to Downdetector, a service for tracking problems in the work of Internet platforms, users from Russia began to complain en masse about the failures of Facebook, Instagram and Twitter. Problems in social networks began on February 25. Over 80% of users sent complaints about the functioning of the application, another 10% noticed that they could not log in to their profile, and 7% reported problems with the operation of social network sites. 

Recall that on February 25, Roskomnadzor (the Federal Service for Supervision of Communications, Information Technology, and Mass Media) partially restricted access to Facebook. On the same day, the Prosecutor General's Office recognized the social network involved in the violation of human rights and freedoms and citizens of Russia. 

On February 26, representatives of Russian media were banned from showing ads and monetization in the social network Facebook. The company took such a step because of the situation around Ukraine. At the same time, Twitter suspended advertising for Russians and Ukrainians, as well as temporarily stopped recommending tweets to avoid the spread of insulting materials. 

In addition, Roskomnadzor restored measures in the form of slowing the speed of Twitter Internet service on devices in Russia in connection with the dissemination of untrustworthy public information about the military operation in Ukraine. 

The agency recalled that since March 10, 2021, Roskomnadzor slowed down Twitter on mobile phones and fixed devices on the territory of the Russian Federation for refusal to delete information that is prohibited in the Russian Federation. On May 17, 2021, after the deletion of more than 91% of the prohibited information by Twitter's moderation services, the restrictions were lifted. 

Roskomnadzor noted that in this situation, the condition for lifting access restrictions "is the complete removal of Twitter of prohibited materials identified by Roskomnadzor, as well as the termination of participation in the information confrontation, distribution of fakes and calls for extremism". 

In the Russian segment of the Internet, you can now often find messages: "If anything, here is my Telegram account...». Since February 25, when Roskomnadzor announced the partial blocking of the Facebook network, almost every Russian user has considered it his duty to notify friends where to look for him now. 

Bloggers and media resources are increasingly posting on their pages posts with recommendations for installing a VPN and other measures to bypass blocking.
