Cryptojacking Cryptojacking Campaign Imperva Imperva Threat Research malware Oracle Weblogic Server Threat research TTPs Vulnerabilities

Imperva Report Previously Undocumented 8220 Gang Activities


Imperva Threat Research team has recently discovered a previously unreported activity from the 8220 gang, which is well-known for mass-deploying a range of constantly evolving TTPs to distribute malware in large quantities. The threat actor has a history of using cryptojacking malware to target Linux and Windows web servers.

The researchers reported the issue in a blog, discussing the group’s attack tactics, recent activities, and indicators of compromise (IoCs) from the threat actor’s most recent campaign. Customers of Imperva are shielded from the known actions of this group. All firms are required to keep their security and patching up-to-date. 

History of the Threat Actor

The 8220 gang, which is believed to be a China-based group, was initially discovered in 2017 by Cisco Talos. The targets include Apache Struts2, Hadoop YARN, and Drupal systems, where the threat actors transmitted cryptojacking malware. Since then, a number of additional researchers have offered updates on the group's growing tactics, methods, and procedures (TTPs), which include making use of vulnerabilities in Log4j and Confluence. The group's use of the Oracle WebLogic vulnerability CVE-2017-3506 to infect specific systems was most recently shown by Trend Micro.

Evolving TTPs

The Imperva Threat Research disclosed the use of malware identified as CVE-2021-44228 and CVE-2017-3506. Also, the researchers revealed that the threat group exploited CVE-2020-14883, a Remote Code Execution vulnerability in Oracle WebLogic Server, to spread malware.

This vulnerability, frequently linked with CVE-2020-14882 (an authentication bypass vulnerability also affecting Oracle Weblogic Server) or using compromised, stolen, or leaked credentials, permits remote authenticated attackers to execute code via a gadget chain. The documented exploitation of these vulnerabilities is extensive. This way, it is easier to modify for the distribution of malware. 

The 8220 gang employs two distinct gadget chains: one allows an XML file to be loaded, and this file contains a call to another gadget chain that allows commands to be executed on the operating system.

The report further notes that Imperva Cloud WAF and on-prem WAF have addressed the issues already by mitigating flaws that were used by the 8220 gang for conducting their malicious activities. Some of these vulnerabilities have been listed below:

  • CVE-2017-3506 – Oracle WebLogic Server RCE 
  • CVE-2019-2725 – Oracle WebLogic Server Authenticated Deserialization 
  • CVE-2020-14883 – Oracle WebLogic Server Authenticated RCE 
  • CVE-2021-26084 – Atlassian Confluence Server OGNL Injection RCE 
  • CVE-2021-44228 – Apache Log4j JNDI RCE 
  • CVE-2022-26134 – Atlassian Confluence Server RCE

Smartphone Keyboard
Android Trojan Cryptojacking malware Malware apps Smartphone Keyboard

Is Malware The Reason Your Smartphone Keyboard is Not Working?


A user is required to be utilizing a function keyboard if he wants to use a smartphone for social media posting, web browsing, or communication with a friend. 

Most problems, faced when a smartphone is not functioning properly, can be resolved by resetting the device, deleting the cache, or installing an alternative keyboard app. But, what if none of that is helpful?

Malware Might Cause Keyboard Malfunctions 

While Android phones are apparently more vulnerable to malwares than any iOS, iPhones as well are vulnerable. If your smartphone’s keyboard glitches, lags, takes a long time to display on the screen or does not respond when you hit the keys, your smartphone may be infected by malware. 

Smartphone keyboards may as well turn malfunctional due to malware since it generally affects the entire device. Malware may cause various issues, like overeating, lags and crashes, a decreased battery life, etc. A user’s personal data and privacy could also be compromised, depending on the kind of malware. 

Malware frequently utilizes a significant amount of computing power; this is what initially causes the performance issues. Since the operating system of your smartphone is impacted, the malware will ultimately affect all the programs installed in it, plus the default keyboard apps. 

What Types of Mobile Malware Would Cause Keyboard Issues? 

A Trojan horse, which is malware imposing as a legit program, is one of the examples. More such malwares may include adware (malware displaying unwanted advertisements), spyware (malware that records information without consent), worms (malicious programs replicating themselves), and cryptojackers.

Cryptojacking attack includes threat actor accessing a targeted device to mine cryptocurrency. Thus, if a smartphone is attacked by a cryptojacker, its processing power would be utilized in order to solve cryptographic equations and create virtual currency for someone else. This would ultimately make the keyboard glitch, resulting in a variety of performance difficulties. 

How to Remove Malware from Smartphones?

If a user suspects malware, that is responsible for affecting a keyboard, the initial caution he should take is by installing and programming an anti-virus software. There are numerous free anti-virus softwares available to users in all major app stores. Although not all would aid in removing the malicious program, they could be utilized to at least detect the malwares. 

Users may as well look out for any unfamiliar or suspicious apps on their phones if they do not remember installing the same. Since there is a good chance for these apps to be deploying malware on your phones. Thus, these apps must immediately be removed, followed by monitoring your device with an antivirus program. 

If none of this works, users are left with one option, i.e. master reset or factory reset. This would eventually restore the affected smartphone to its initial state when it was first powered up. However, this will lead your device to compromise its entire data, unless it is backed up somewhere so that you could retrieve it once the reset is successfully executed.

Cryptojacking Cyber Attacks OneDrive Ransomware Spyware

Cryptojacking Campaign Exploits OneDrive Vulnerability, Can Deploy Spyware and Ransomware Too


New cryptojacking campaign

Cryptojacking is becoming a nightmare for customers and enterprises, and threat actors have started using various techniques to deploy cryptojackers on victims' systems. As per recent developments, cybersecurity software developer Bitdefender found a crypto jacking campaign exploiting Microsoft OneDrive vulnerability to get access and run without getting caught on compromised devices. 

BitDefender report says:

"OneDrive was specifically chosen in this attack because it permits the actor to achieve easy persistence. Adding OneDrive to startup is an action done by the dropper malware, but even if it did not do so, OneDriveStandaloneUpdater.exe is by default scheduled to execute each day. Of the detections we received, 95.5% came from OneDriveStandaloneUpdater.exe loading the malicious secur32.dll."

From May 1 to July 1, Bitdefender identified around 700 users impacted by the campaign. The campaign operates using four cryptocurrency mining algorithms- Ton, XMR, Ethash, and Etchash. It makes an average of $13 worth of cryptocurrency per compromised device.

Cryptojacking uses OneDrive sideloading bug

Cryptojacking is an unauthenticated exploit of computer manufacture for mining cryptocurrency. The threat actors in the recent cryptojacking campaign used a DLL sideloading vulnerability in OneDrive by writing a fake secur32.dll file. After the file is loaded into the OneDrive process, the fake secur32.dll will download open-source cryptocurrency mining software and install it into genuine Windows processes. 

Sideloading is basically installing a code that has not been approved for running on a system by the developer of the machine's operating system. DLL files are a combination of small programs having instructions that can assist a larger program finish non-core tasks of the original program. 

The campaign also uses Spyware, Ransomware

Meanwhile, the OneDrive sideloading campaign is used only in cryptojacking, DLL side-loading is also used for the deployment of ransomware or spyware. Besides this, as cryptocurrency minutes are resource-sensitive, the victims can instantly see falling CPU and GPU performance, increased energy consumption, and overheating, these issues can ruin expensive hardware. 

OneDrive, by default, is set to reboot on a daily basis, and the threat actors behind the latest cryptojacking campaign were found to run the OneDrive.exe process to run after a reboot, even if the user shuts it down. The attackers use this method to gain persistence. In 95% (estimated) of the findings, the scheduled reboot was found to deploy the infected secur32.dll. 

"Given that the “per machine” installation method may not be suitable for all environments and privilege levels, user caution should be one of the strongest lines of defense against commodity malware. Bitdefender recommends that users ensure their AVs and operating systems are up to date, to avoid cracked software and game cheats, and to download software from trusted locations only"-Bitdefender report.

Hacked Devices Generated $53 for Every $1 Cryptocurrency Through Crypto Jacking

 


The team of security researchers evaluated the financial impact of crypto miners affecting cloud servers. They stated that this costs cloud server victims about $53 for every $1 of cryptocurrency mined by threat actors through crypto-jacking. 

Cryptojacking refers to the illegal method of extracting cryptocurrency from unauthorized devices, including computers, smartphones, tablets, and even servers with an intent of making a profit. Its structure allows it to stay hidden from the victims. The malicious actors generate income through hijacking hardware, as the mining programs use the CPUs of hijacked devices.  

The mining of cryptocurrency through the hijacked devices was primarily an activity of financially motivated hacking groups, especially Team TNT. It was responsible for most of the large-scale attacks against vulnerable Doctors Hub, AWS, Redis, and Kubernetes deployments.  

The cyber attackers updated the OS image by distributing the network traffic across servers that contained XMRig. It is a CPU miner for a privacy-oriented hard-to-trace cryptocurrency that has recently been considered the most profitable CPU mining.   

As opposed to ransomware, software that blocks access to systems until the money is paid, and includes aggressive law enforcement, rouge crypto mining is less risky for the cyber attackers.  

The Sysdig researchers used "Chimaera", a large campaign of TeamTNT for estimating the financial damage caused by crypto miners. The research revealed that over 10,000 endpoints were disclosed to unauthorized persons. 

In order to hide the wallet address from the hijacked machines and make tracking even harder, the cyber-attackers used XMRig-Proxy but the analysts were still able to discover 10 wallet IDs used in the campaign. 

Later the researchers disclosed that the 10 wallets held a total of 39XMR, valuing $8,120. However, they also mentioned that the estimated cost to victims incurred from mining those 29 XMR is $429,000 or $11,000 per 1 XMR. 

Moreover, they explained that, according to their estimates, the amount does not include amounts that are stored in unknown older wallets, the damage suffered by the server owner as a result of hardware damage, the potential interruptions of online services caused by hogging processing power, or the strategic changes firms had to make to sustain excessive cloud bills as a result of hogging processing power.

Microsoft Facing a Growing Threat by Cryptojackers

 

Cryptojackers, are still invading computers all over the world while also getting more discreet and skilled at evading detection. The data was released by Microsoft's 365 Defender Research Team, which on Thursday posted a new analysis of cryptojackers on its blog.

Microsoft Defender Antivirus detects cryptojackers on more than 200,000 devices per day using a variety of sensors and innovative detection techniques, including its connection with Intel TDT. In campaigns, hackers strongly favor the exploitation of notepad.exe over several valid system utilities.

What are Cryptojackers?

Cryptojackers are mining viruses that hijack and use a target's device resources for the former's gain without the user's knowledge or approval. They are one of the threat categories that have emerged and thrived since the advent of cryptocurrencies. The threat data indicates that over the past year, companies have encountered millions of cryptojackers.

Furthermore, as per Microsoft, Javascript is frequently used in the creation of cryptojackers, which in this instance use browsers to infiltrate systems. The tech titan also cautioned against fileless cryptojackers, who mine in a device's memory and maintain persistence by abusing legal programs and LOLBins.

Cryptojacking operation

Among several legitimate system utilities, notepad.exe abuse is heavily favored by attackers in campaigns that have been observed. An improved version of the cryptojacker known as Mehcrypt was employed in this campaign. 
  • This is a significant improvement over the previous version, which used a script to access its command-and-control (C2) server and download additional components that later carried out malicious deeds. 
  • The new version also condenses all of its routines into a single script and connects to a C2 server in the final stage of its attack chain.
  • An archive file containing autoit.exe and a heavily obscured, arbitrarily named.au3 script serves as the threat's delivery vehicle. 
  • Autoit.exe is started when the archive file is opened, and it decodes the.au3 script in memory. 
  • When the script is executed, it continues to decode more obfuscation layers and loads more decoded scripts into memory.
  • The script then places a copy of itself and autoit.exe in a folder with an arbitrary name under C:ProgramData.
  • To run the script each time the device begins, the script inserts autostart registry entries and generates a scheduled task to destroy the original files.
  • The software then incorporates persistence methods, loads malicious code into VBC.exe using process hollowing, and establishes a connection to a C2 server to wait for commands. 
  • The software loads its cryptojacking code into notepad.exe using process hollowing based on the C2 answer.

The warning was issued just a few weeks after Microsoft released a study describing how a widespread phishing effort managed to steal sign-in credentials, hijack sign-in sessions, and bypass the authentication step even when multi-factor authentication (MFA) was turned on.

Cloud based services Cryptocurrencies Cryptojacking malware Researchers

CoinStomp Malware is Aimed at Asian Cloud Service Providers

 

Researchers have uncovered a new malware family that mines cryptocurrencies using cloud services. According to Cado Security, the malware, dubbed CoinStomp, is comprised of shell scripts that "try to target cloud compute instances hosted by cloud service providers for the purpose of mining cryptocurrencies." According to the company's researchers, the overall goal of CoinStomp is to silently breach instances in order to harness computational resources to illicitly mine for cryptocurrency, a type of attack known as cryptojacking. 

So far, a handful of attacks have targeted cloud service companies in Asia. Clues in code also referenced Xanthe, a cryptojacking threat group previously linked to the Abcbot botnet. However, the clue – found in a defunct payload URL – is insufficient to determine who is behind CoinStomp and may have been included in an "attempt to dodge attribution," according to the team. 

CoinStomp includes a variety of intriguing features. One example is its reliance on "timestomping." Timestomping is the process of modifying the timestamps of files dumped or used during a malware attack. This approach is commonly used as an anti-forensics strategy to confound investigators and thwart remedial efforts. Although the Rocke gang has previously utilized timestomping in cryptojacking assaults, it is not a common technique. On Linux, timestomping is simple with the -t flag of the touch command. 

"It seems likely that timestomping was employed to obfuscate usage of the chmod and chattr utilities, as forensic tools would display the copied versions of these binaries as being last accessed (executed) at the timestamp used in the touch command," Cado Security noted. 

Furthermore, the malware will attempt to mess with the cryptographic policies of Linux servers. Because these policies can prevent malicious executables from being dumped or run, the creator of CoinStomp has included options to disable system-wide cryptographic policies via a kill command. "This could undo attempts to harden the target machine by administrators, ensuring that the malware achieves its objectives," the researchers say. 

CoinStomp will then use a reverse shell to connect to its command-and-control (C2) server. The script then downloads and runs additional payloads as system-wide systemd services with root access. These include binaries that might be used to develop backdoors and a customized version of XMRig, which is genuine Monero mining software that has been abused for criminal purposes.

cryptocurrency Cryptojacking Nagois XI Vulnerabilities and Exploits XMRig

Nagios XI Servers: Seems to be Turning Into Cryptocurrency Miners for Attackers

 

Nagios XI is a popular enterprise server and network monitoring solutions. The feature “Configuration Wizard: Windows Management Instrumentation (WMI)” is being exploited in Nagios XI. 

On March 16, 2021, Unit 42 researchers observed an attacker targeting Nagios XI software to exploit the vulnerability CVE-2021-25296, a remote command injection vulnerability impacting Nagios XI version 5.7.5, to conduct a cryptojacking attack and deploy the XMRig coin miner on victims’ devices.

The XMRig coin miner is an open-source cross-platform cryptocurrency miner. If the attack is successful, the XMRig coin miner will be installed on the compromised devices. The vulnerability can be lessened by updating Nagios XI to the most recent update. 

In order to understand if a device is compromised and running XMRig miner, users can either:
1.Execute commands ps -ef | grep 'systemd-py-run.sh\|systemd-run.py\|systemd-udevd-run.sh\|systemd-udevd.sh\|systemd-udevd.sh\|workrun.sh\|systemd-dev' and check the result. If the processes of the mentioned scripts are running, the device might be compromised. 

2.Check the files in the folder /usr/lib/dev and /tmp/usr/lib to see if the mentioned scripts exist or not. If they exist, the devices might be compromised. If the system is discovered to be hacked, simply terminating the operation and deleting the scripts will remove the XMRig used in the attack. 

The attacks try to execute a malicious bash script fetched from the malicious server 118[.]107[.]43[.]174. The bash script dropped by the attacker downloads the XMRig miner from the same server where the script is hosted and releases a series of scripts to run the XMRig miner in the background. Once the attack succeeds, the devices will be compromised for cryptojacking. 

The attack targeting Nagios XI 5.7.5, exploits CVE-2021-25296 and drops a cryptocurrency miner, jeopardizing the security of systems running out-of-date Nagios XI applications. 

Cryptojacking malware-infected devices can experience performance degradation. Furthermore, the attacker could modify the script online, causing the new script to be automatically downloaded and executed on the compromised computers, resulting in additional security risks. 

Security subscriptions protect Palo Alto Networks Next-Generation Firewall customers from the vulnerability: 
1.Threat Prevention can block attacks with Best Practices through Threat Prevention signature 90873. 
2. Static signature detections in WildFire can avoid malware. 
3.Malicious malware domains can be blocked using URL filtering.

Cryptojacking malware pro-ocean Rocke group

Cybersecurity Researchers Identifies an Updated Variant of 'Pro-Ocean' Malware

 

Cybersecurity experts have discovered an updated version of ‘Pro-Ocean malware’, this malware was used as a weapon by a cybercriminal gang called Rocke Group to target cloud infrastructure with crypto-jacking strikes.

Cybersecurity experts first discovered the Pro-Ocean malware in 2019 and it has evolved to be even more deadly due to its worm capabilities and rootkit detection evasion features. Aviv Sasson with Palo Alto Networks stated that "this malware is an example that demonstrates that cloud providers’ agent-based security solutions may not be enough to prevent evasive malware targeted at public cloud infrastructure."

The Rocke Group has expanded its targeting of cloud applications such as Oracle WebLogic, ActiveMQ, and open-source data structure store Redis for mining Monero. Pro-Ocean malware has been on the radar of many cybersecurity firms since these attacks occurred. The latest malware targets to bypass these detection and mitigation efforts.

Pro-Ocean malware exploits various known vulnerabilities to target cloud applications which includes a severe flaw in Apache ActiveMQ (CVE-2016-3088) and a high severity susceptibility in Oracle WebLogic (CVE-2017-10271). The malware is also known to target vulnerable instances of Redis. After the malware is downloaded it strives to detach other malware and cryptominers, including BillGates, XMRig, Luoxk, and Hashfish. Once downloaded, it kills any process that utilizes the CPU heavily so that it is capable of using 100% of the CPU and mine Monero effectively.

Pro-Ocean malware has four components: A rootkit module that downloads a rootkit and various other malicious services; a mining module that operates the XMRig miner; a Watchdog module that implements two Bash scripts (for checking that the malware is operating and finding out any processes using CPU heavily); and an infection module that carries ‘worm’ capabilities. The latest ‘worm’ feature is a new inclusion for Pro-Ocean malware, which previously have targeted the victims manually, Python infection script is now used by malware to acquire the public IP address of the victim’s machine.

Pro-Ocean malware does this to secure online service with the domain ‘ident.me’ which extends out IP addresses for various web servers and then the script attempts to corrupt all the machines in the same 16-bit subnet (e.g., 10.0.X.X).

In this regard, cybersecurity researchers explained that “cryptojacking malware targeting the cloud is evolving as attackers understand the potential of that environment to mine for crypto coins. We previously saw simpler attacks by the Rocke Group, but it seems this group presents an ongoing, growing threat. This cloud-targeted malware is not something ordinary since it has worm and rootkit capabilities. We can assume that the growing trend of sophisticated attacks on the cloud will continue”.

Sonicwall Cyber Threat Report 2019 Finds Escalation in Ransomware Attacks-As-A-Service


Based on the real world data from more than 1 million international security sensors in more than 200 nations, SonicWall made public the discoveries from its mid-year update of the 2019 through the 'SonicWall Cyber Threat Report'.

With the global malware volume going down by 20%, researchers found a 15% increment in ransomware attacks comprehensively.

This expansion in ransomware-as-a service, open-source malware kits and cryptojacking utilized by cybercriminals comprised of the major highlights of the new data found.

"Organizations continue to struggle to track the evolving patterns of cyber-attacks — the shift to malware cocktails and evolving threat vectors — which makes it extremely difficult for them to defend themselves," said SonicWall President and CEO Bill Conner.

"In the first half of 2019, SonicWall Real-Time Deep Memory Inspection (RTDMI) technology unveiled 74,360 'never-before-seen' malware variants. To be effective, companies must harness innovative technology, such as machine learning, to be proactive against constantly-changing attack strategies,” he added later.

In the first part of 2019, SonicWall also observed a 55% increase in IoT attacks, a number that outpaces the initial two quarters of the previous year, all because organizations and purchasers keep on connecting devices to the web without appropriate safety measures.

Confluence servers Cryptojacking cybercriminals hack malware Servers hacked

Confluence servers hacked to install malware

Cybercriminals are now exploiting a vulnerability in Confluence servers to install cryptojacking malware. According to a report by Trend Micro, the vulnerability has been well documented in the past. However, at the time, it was being used to target victims with DDoS attacks.

Confluence is a widely popular planning and collaboration software developed by the Australian software giant, Atlassian. Trend Micro reported that it had noticed one of the vulnerabilities, CVE-2019-3396, in April, a month after Atlassian published an advisory covering the same. CVE-2019-3396 is a template injection in the Widget Connector that allows cybercriminals to execute code remotely on their victims’ machines.

The vulnerability was first used for a DDoS attack in Romania. However, the cybersecurity and analytics company revealed that hackers are now using it to install a Monero crypto miner that comes with a rootkit. The rootkit serves to hide the malware’s network activity. It also shows false CPU usage on the affected machine, misleading the user and further concealing the mining process. The report further revealed that the rootkit re-installs the malware should the victim manage to remove it.

The attack begins by sending a command to download a shell script hosted on Pastebin, an online content hosting service where users store plain text for a set period of time. The malware then kills off some of the processes running on the host machine before downloading other resources, also from Pastebin.

The vulnerability mainly targets older versions of Confluence, with Atlassian urging its users to download patched versions of Confluence Server and Data Center to protect themselves.

In recent times, cryptojacking has become increasingly popular with cybercriminals. The tactics are also advancing, with the criminals seeking to stay ahead of the security experts. As we reported recently, a new malware that targets Linux servers has been modified to shut down other crypto miners in the host’s system. Known as Shellbot, the malware uses the SSH brute force technique to infect servers that are connected to the internet and that have a weak password.

Malware Campaigns Attacking Asian Targets Using EternalBlue and Mimikatz



Asian targets are falling prey to a cryptojacking campaign which takes advantage of 'Living off the Land' (LotL) obfuscated PowerShell-based scripts and uses EternalBlue exploit to land Monero coinminer and Trojans onto targeted machines.
At the beginning of this year, a similar malware campaign was identified by the research team of Qihoo 360; reportedly, the campaign was targeted at China at the time. Open source tools such as PowerDump and Invoke-SMBClient were employed to carry out password hashing and execute hash attacks.
The campaign resorts to an exploit which uses SMBv1 protocol which was brought into the public domain by the Shadow Brokers a couple of years ago. It has now become one of the standard tools used by the majority of malware developers.
Referenced from Trend Micro’s initial findings, the aforementioned cryptojacking campaign was only targeting Japanese computer devices but eventually the targets multiplied and now they encompassed Taiwan, India, Hong-Kong, and Australia.
Trend Micro’s research also stated that the EternalBlue exploit, developed by NSA is a new addition into the malware; alongside, they drew a co-relation between the exploit and the 2017 ransomware attacks.  
How does the malware compromise computers?
With the aid of "pass the hash" attacks, it inserts various infectious components into the targeted computer by trying multiple weak credentials in an attempt to log in to other devices which are connected to that particular network.
Upon a successful login, it makes changes in the settings concerning firewall and port forwarding of the compromised machine; meanwhile, it configures a task which is scheduled to update the malware on its own.
Once the malware has successfully compromised the targeted computer, it goes on to download a PowerShell dropper script from C&C server and then it gets to the MAC address of the device and terminates the functioning of all the antimalware software present on the system. Immediately after that, it furthers to place a Trojan strain which is configured to gather the information of the machine such as name, OS version, graphics detail, GUID and MAC address.
“We found the malware sample to be sophisticated, designed specifically to infect as many machines as possible and to operate without immediate detection. It leverages weak passwords in computer systems and databases targets legacy software that companies may still be using,” said Trend Micro.
Trend Micro advises users and enterprises to, “use complicated passwords, and authorize layered authentication whenever possible. Enterprises are also advised to enable multi-layered protection the system that can actively block these threats and malicious URLs from the gateway to the endpoint.”

Crypto-jacking: A New Vector of the Cyber-Cons after Ransomware!




Apparently, according to the records of 2018, after getting bored with ransomware attacks, crypto-jacking has become the new tool of cyber-cons for harvesting crypto-currency.



Crypto-jacking by nature is more insidious and stealthy and hence in the past year has emerged as a better way of harvesting crypto-currency.

Initially, the best choice for doing the same was ransomware, but having surpassed it, Crypto-jacking is now cyber-cons’ favorite option.

2018, unlike any other year in the cyber-crime history saw a lot of cyber-attacks, wherein the crypto-jacking attacks constituted to be amongst the most.

The report of IBM strictly mentioned that the crypto-currency attacks hiked by quite a large number.

Whereas, ransomware attacks plummeted by 45% including both mobile and desktop platforms.

The major reason behind this shift of inclination towards crypto-jacking happens to be the less-disruptive and furtive disposition.

After a ransomware is introduced to the victim, the attack weapon goes waste after just one attack, leaving no chances for a recurrence.

Meanwhile, in the case of crypto-jacking, a recurrence is almost ensured, making it possible for more profits from a single weapon.

Somehow, crypto-jacking appears to be the more malicious of the two, which if ignored could lead to serious ramifications.

Reportedly, crypto-jacking could soon transform from currency mining to fabrication its own botnets to function spyware attacks.

Leaving the users with the only advice and option; to use the latest versions of anti-viruses and keep the systems updated.

In-Browser Cryptomining Service, 'Coinhive' to Shut Down on March 8, 2019



Coinhive, an in-browser Monero cryptocurrency miner which was designed to provide web developers a JavaScript will be terminating its operations soon.  

Officials at Coinhive put the news forth in a blog post on February 26 where they cited various reasons for their decision of shutting down all their operations. The post suggested that following a 50 percent drop in hash rate, Cryptocurrency service, Coinhive decided to discontinue its operations on March 8, 2019.  

Referencing from the blog post, "The drop in hash rate (over 50%) after the last Monero hard fork hit us hard," the company said. "So did the 'crash' of the crypto currency market with the value of XMR depreciating over 85% within a year."

"This and the announced hard fork and algorithm update of the Monero network on March 9 has lead us to the conclusion that we need to discontinue Coinhive," said the officials.

The project which no longer is economically viable was launched in September 2017 as an alternative to traditional banner ads.

Before Coinhive’s in-browser Monero mining stops working on March 8, the registered users will be made dashboards accessible until April 30 so that they can withdraw funds from their respective accounts.

The digital currency mining service, despite the consistent efforts of the team never become one of the major websites in the league. Moreover, it was subjected to heavy criticism for skyrocketing the CPU usage inside browsers. 

Afterward, it went on becoming immensely popular among cybercriminals for cryptojacking and recently a report from Kaspersky Labs suggested that cryptojacking left behind ransomware and became the biggest cybersecurity threat. 

Referencing from the announcement made by the company,

“Some of you might have anticipated this; some of you will be surprised. The decision has been made. We will discontinue our service on March 8, 2019. It has been a blast working on this project over the past 18 months, but to be completely honest, it isn’t economically viable anymore.”

“The drop in hash rate (over 50%) after the last Monero hard fork hit us hard. So did the “crash” of the cryptocurrency market with the value of XMR depreciating over 85% within a year. This and the announced hard fork and algorithm update of the Monero network on March 9 has lead us to the conclusion that we need to discontinue Coinhive.”

Docker Engine API
Coin Mining Cryptojacking Docker Engine API

Exposed Docker Apis Used By Attackers In Creation Of New Containers That Perform Cryptojacking


Earlier this year it was revealed that attackers are now utilizing insecure Docker And Kubernetes systems in order to redistribute containers that have been used to mine coins. These containers are packages that include an application and all of the dependencies that are needed to run it. The packages are then redistributed as containers to Docker or Kubernetes structures accordingly.

Even Trend Micro lately detected an attacker scanning explicitly for insecure and exposed Docker Engine APIs and its utilization to deploy containers that download and execute a coin miner.
Docker containers are redistributed on a rostrum referred to as the Docker Engine, wherein they may run within the background together with different containers deployed to the system. 

If Docker Engine isn't accurately safeguarded, attackers can remotely make use of the Docker Engine API to redistribute the containers in their very own advent and start them at the insecure system.
Container Creation

When the container is deployed and stimulated, it releases an auto.sh script that further downloads a Monero miner and configures it to launch instinctively. The script even downloads the port scanning software, in an effort to test for the various vulnerable Docker Engine instances on port 2375 and 2376 and additionally try to spread to them.

Scan all networks seen from the host, with a scan rate of 50,000 packets per second, for open port 2375 and 2376; the result is saved in local.txt (anonymized/defanged):
masscan “$@” -p2375,2376 –rate=50000 -oG local.txt;
Conduct lateral movement by infecting or abusing more hosts found in previous reconnaissance:
sudo sed -i ‘s/^Host: \([0-9.]*\).*Ports: \([0-9]*\).*$/\1:\2/g’ local.txt;
sudo sh test3.sh local.txt;


With this method, a whole lot of Docker Engine containers can be gathered that mine coins for the attacker.

Although Docker Engine API abuse isn't new, but it continues to be a hassle due to the fact that the administrators don't legitimately secure their systems. To keep attackers from abusing the insecure Docker Engine implementations, Trend Micro proposes that the administrators  make use of the following security measures:


  • Harden the security posture. The Centre for Internet Security (CIS) has a reference that can help system administrators and security teams establish a benchmark to secure their Docker engine.     
  • Ensure that container images are authenticated, signed, and from a trusted registry (i.e., Docker Trusted Registry). Employing automated image scanning tools helps improve development cycles.  
  • Enforce the principle of least privilege. For instance, restrict access to the daemon and encrypt the communication protocols it uses to connect to the network. Docker has guidelines on how to protect the daemon socket.
  •   Properly configure how much resources containers are allowed to use (control groups and namespaces).
  • Enable Docker’s built-in security features to help defend against threats. Docker has several guidelines on how to securely configure Docker-based applications

A Mysterious Malware That Holds The Power To Critically Damage One’s Phone

It wouldn't be wrong to state that Hack forums isn't the most "world class"  or elite gathering of cybercriminals as many of  its members as of now appear to be relative novices, and furthermore it's probable that some post about hacking methods they've never really endeavoured. In spite of the fact that experts do state that with the current buyer showcase in cryptocurrencies, even the refined hacking groups are increasingly getting into undercover or in other words clandestine mining, and once in a while running such operations close by more customary and traditional  cybercrime like data theft and dissent of service attacks.

In the same way as many other people, the hackers on the message board Hack Forums are presently exchanging tips on the most proficient method to make profit with cryptocurrencies. Be that as it may, they're not simply hoping to purchase low and offer high they are only swapping approaches to surreptitiously tackle other people's phones and PCs to further generate digital coins for themselves.

A month ago, F5 networks, a Seattle security firm reported a "sophisticated multi-stage attack" hijacking networks of computers to mine cryptocurrencies.

The assailants have been known to utilize the vulnerabilities in common server softwares, combined with Windows exploits leaked from the National security Agency, to effortlessly infiltrate the victim's systems and migrate through their networking systems.

Despite the fact that it's difficult to know how much these current crypto jacking attacks have earned altogether, yet the addresses connected to the malware variations seemed to have gotten a sum of $68,500 in the cryptographic money (cryptocurrency) monero.

In any case, in the previous year, monero-mining malware has been spotted on an extensive variety of sites, mining the currency as people streamed videos from Showtime and Ultimate Fighting Championship or only browsed the web on compromised Wi-Fi systems at Starbucks cafes. Albeit, some program expansions have been found mining the currency while the users do other things, and monero-mining malware has as of late been spotted proliferating through links on Facebook Messenger also.

Hi @Starbucks@StarbucksAr did you know that your in-store wifi provider in Buenos Aires forces a 10 second delay when you first connect to the wifi so it can mine bitcoin using a customer’s laptop? Feels a little off-brand...

“If you remember the IoT botnets, Mirai in the past, we’ve actually seen one variant this year which was mining monero coins on routers and hard disk recorders as well,” says Candid Wueest, principal threat researcher at Symantec and contributing author on a report the security company released on cryptojacking last month.

Creators of some monero-mining software argue that in-program (browser) mining can have a true blue use, letting people intentionally exchange computer power for access to articles, videos, or premium application features, when sites are looking past publicizing or advertising as an income and revenue stream. "I don't agree with anybody's computer being mishandled or abused without their insight," says Spagni, the monero core developer.

"However the technology that is being manhandled presents a completely new approach for monetizing a service on the web." He contends this could empower a "free" version of Netflix or provide another subsidizing stream for journalism.

Coinhive one of the most well-known web miners, even offers a mining-based captcha alternative, aimed at making it less attainable for spammers to play out specific activities on a website, and a version of the software called AuthedMine which requires the users to unequivocally opt in before mining begins. Makers of other mining tools put forth comparable expressions about user consent, maybe with changing degrees of sincerity.

Nevertheless a tool called Monero Quiet Excavator, available for $14, mines in the background on Windows PCs. It doesn't launch a visible window that users can recognize or detect as fast as possible, keeps the gadgets from going into sleep mode, and can "bypass firewalls," as indicated by its website. In any case, its developer states that it is intended just for "legitimate users". Those could incorporate individuals who possess various PCs and need to utilize them to mine monero "transparently for the end user or client of the PC"
