Millions of Facebook Users' Credentials Were Stolen via Authentic App Services

 

The phishing effort used Facebook and Messenger to deceive millions of consumers into visiting advertising pages and websites where personal account information was exposed. 

The phishing campaign used messages through messenger to entice users to open the link, thus the pop-up requested for account credentials, which unsuspecting consumers provided by filling out the phishing form with their login and password. The campaign operators used the hacked accounts to send more hacker messages to their friends, earning a lot of money through internet advertising fees.

The effort peaked in April-May 2022 but has been active since at least September 2021, as per PIXM, a New York-based AI-focused cybersecurity business. Since one of the identified phishing pages included a link to a publicly accessible traffic monitoring app (whos.amung.us) without authentication, PIXM was able to track down the threat actor and map the campaign. 

Over 405 different usernames were uncovered by PIXM, each of which was linked to a distinct phishing landing page. In 2022, one username, teamsan2val, got 6.3 million views, up 128 percent from 2021. All of these usernames had a total of 399,017,673 sessions. The phishers also informed an OWASP researcher who claimed they made roughly $150 for every thousand visitors from the United States. This equates to $59.85 million in total revenue.

These 405 usernames, as per the researchers, are merely a small portion of the total number of accounts employed in the effort. The second wave of redirections begins after the victim inputs the credentials on the phishing landing page, bringing visitors to advertising pages, survey forms, and so on. These redirects provide referral revenue for the threat actors, which is believed to be in the millions of dollars at this scale. One may deduce three things about the malicious attacks going on based on these new discoveries and disclosures. These are the attacks: 
  • Software-based
  • Growing at an exponential rate 
  • Vulnerable populations are targeted

On all landing pages, PIXM discovered a common code snippet that contained a reference to a website that had been seized as part of an investigation against a Colombian individual named Rafael Dorado. It's unclear who took control of the domain and posted the message.

A reverse whois search turned up links to a real web development company in Colombia, as well as ancient websites selling Facebook "like bots" and hacking services. 

The results of PIXM's inquiry were shared with the Colombian Police and Interpol, but the campaign is still ongoing, although many of the identified URLs have been offline.

Even When Switched Off, iPhones are Vulnerable to Attack

 

The way Apple combines autonomous wireless technology such as Bluetooth, Near Field Communication (NFC), and Ultra-wideband (UWB) in the device, researchers determined that it could be exploited by attackers to target iPhones even when they are turned off. 

Such features—which have access to the iPhone's Secure Element (SE), which stores sensitive information—stay on even when modern iPhones are turned off, as per a team of researchers from Germany's Technical University of Darmstadt. This allows attackers to "load malware onto a Bluetooth chip that is performed when the iPhone is off," according to a research study titled "Evil Never Sleeps: When Wireless Malware Stays On After Turning Off iPhone."

As per Jiska Classen, Alexander Heinrich, Robert Reith, and Matthias Hollick of the university's Secure Mobile Networking Lab, attackers can gain access to secure information such as a user's credit card data, banking details, or even digital car keys on the device by compromising these wireless features. Researchers noted that while the risk is real, exploiting the circumstance is not that simple for would-be attackers. Threat actors will still need to load malware onto the iPhone when it is turned on for subsequent execution when it is turned off. This would require system-level access or remote code execution (RCE), which they might gain by exploiting known weaknesses like BrakTooth. 

The main cause of the problem is the existing implementation of low power mode (LPM) for wireless chips on iPhones. The experts distinguished between the LPM which these processors employ and the power-saving program that iPhone users can use to save battery life. Because LPM support is built into the iPhone's hardware, it cannot be deleted with system upgrades, and has "a long-term impact on the broader iOS security paradigm," according to the researchers.

Analysts disclosed their findings to Apple before publishing the study, but they claim the company did not respond to the difficulties revealed by their findings. It is recommended that one possible solution would be for Apple to implement "a hardware-based switch to disconnect the battery" so that these wireless parts would not have power while an iPhone is turned off.

Dark Web: 31,000 FTSE 100 Logins

 

With unveiling the detection of tens of thousands of business credentials on the dark web, security experts warn the UK's largest companies that they could unintentionally be exposed to significant vulnerability. Outpost24 trawled cybercrime sites for the compromised credentials, discovering 31,135 usernames and passwords related to FTSE 100 companies using its threat monitoring platform Blueliv.

The Financial Times Stock Exchange (FTSE) 100 Index comprises the top 100 companies on the London Stock Exchange in terms of market capitalization. Across several industry verticals, these businesses reflect some of the most powerful and lucrative businesses on the market. 

The following are among the key findings from the study on stolen and leaked credentials: 

  • Around three-quarters (75%) of these credentials were obtained by traditional data breaches, while a quarter was gained through personally targeted malware infections. 
  • The vast majority of FTSE 100 firms (81%) had at least one credential hacked and published on the dark web, and nearly half of FTSE 100 businesses (42%) have more than 500 hacked credentials. 
  • Since last year, there were 31,135 hacked and leaked credentials for FTSE 100 organizations, with 38 of them being exposed on the dark web. 
  • Up to 20% of credentials are lost due to malware infections and identity thieves.
  • 11% disclosed in the last three months (21 in the last six months, and 68% for more than a year) Over 60% of stolen credentials come from three industries: IT/Telecom (23%), Energy & Utility (22%), and Finance (21%). 
  • With the largest total number (7,303) and average stolen credentials per company (730), the IT/Telecoms industry is the most in danger. They are the most afflicted by malware infection and have the most stolen credentials disclosed in the last three months.
  • Healthcare has the biggest amount of stolen credentials per organization (485) due to data breaches, as they have become increasingly targeted by cybercriminals since the pandemic started. 

"Malicious actors could use such logins to get covert network access as part of "big-game hunting" ransomware assault. Once an unauthorized third party or initial access broker obtains user logins and passwords, they can either sell the credentials on the dark web to an aspiring hacker or use them to compromise an organization's network by bypassing security protocols and progressing laterally to steal critical data and cause disruption," Victor Acin, labs manager at Outpost24 company Blueliv, explained.

WhatsApp Voice Message Phishing Campaign

 

Recently Armorblox researchers have discovered that the new WhatsApp phishing campaign is targeting users by impersonating WhatsApp's voice message feature, in one of their latest researches.

At least 27,655 email addresses have been targeted by a phishing campaign spoofing WhatsApp's voice message attempting to spread information-stealing malware. This phishing campaign is designed to lead the users through a series of steps that will ultimately end with the installation of an information-stealing malware infection which further will open the way to credential theft. 

Following the incident, researchers released a statement in which they have explained the entire fraudulent process and also warned to identify signs of fraudulent activity for users to better protect themselves from phishing attempts. 

The researchers said that the malicious actors are using the "Whatsapp Notifier" service with an address owned by the Center for Road Safety of the Moscow Region, which notifies recipients regarding a new private message, with the email including a "Play" button, as well as the duration of the audio clip and details regarding the creation of the message. 

Clicking on the "Play" button will redirect recipients to a website that will trigger an allow/block prompt for JS/Kryptic trojan installation, with users lured to click "Allow" to confirm that they are not a robot. Selecting "Allow" would then prompt the installation of the information-stealing malware.

Looking into the issue for Digital Journal Josh Rickard, Security Automation Architect at Swimlane said “Phishing attacks are one of the most common methods of cyberattacks and, unfortunately, have become all too easy for cybercriminals to leverage.” In terms of how this form of attack works, he continues: “ These types of social engineering attacks that exploit human error are highly effective and well-masked. In this case, WhatsApps’s voice message feature was manipulated in an attempt to spread information-stealing malware to over 27,000 email addresses associated with the app.”

FBI Warns Election Officials of Credential Phishing Attacks

 

Recently, on Tuesday the Federal agency of United states FBI has released a warning report regarding the US election officials being targeted in an ongoing and widespread phishing campaign by unidentified malicious actors in an attempt to steal their credentials since at least October 2021. 

FBI revealed that the group of hackers has used various methods to redirect their targets to phishing pages and trick them into entering their login credentials. Reportedly, hackers used compromised email addresses of US government leaders to spoof US businesses. 

"If successful, this activity may provide cyber actors with sustained, undetected access to a victim's systems," the FBI said in a private industry notification.

"…As of October 2021, US election officials in at least nine states received invoice-themed phishing emails containing links to websites intended to steal login credentials." 

According to the FBI intelligence, the threat actors have targeted the officials in the three separate "coordinated" phishing attacks and breached accounts of elected officials across at least nine states, Additionally, representatives of the National Association of Secretaries of State were also impacted in October. 

The first attack came to light on 5 October when unrecognized hackers used two email addresses, one from the compromised account of a government official, in an attempt to steal the login data of elected leaders. Less than two weeks later, two identical phishing attacks had been seen from the email addresses linked to US businesses. 

It has been noticed that in each phishing attack, the group of attackers sent an email recognized as "INVOICE INQUIRY.PDF,” which once opened, redirected users to a credential-harvesting website.

Following the incident, the FBI and the US federal law enforcement agency said that the threat “is still very real” and is heading into the 2022 election season. The group of hackers who are behind this phishing campaign will likely continue the attacks against US election officials with new phishing emails as the 2022 midterm elections are closing in. 

The threat intelligence asked network defectors to educate officials against these attacks on how to identify phishing, social engineering, and spoofing attempts and how to protect their systems against such common threats.

Threat Actors Use QR Codes to Steal Login Credentials

 

Hackers are distributing phishing mails having QR codes in a cyberattack campaign built to extract login details of Microsoft 365 cloud apps. Passwords and usernames for cloud services of entreprises have become a main target for hackers, exploiting these to launch ransomware and malware attacks, or by selling stolen login details to other threat actors, who exploit it for their own campaigns. 

Threat Actors are finding sneaky opportunities to scam victims into opening malicious links that lead to phishing websites built to look like genuine Microsoft login webpages, and smartly selling the login credentials. 

Cybersecurity experts at Abnormal Security analyzed a recent campaign, the researchers sent various phishing mails which tried to use QR codes built to evade mail protections and steal login details. QR codes are useful when it comes to attempts malicious tasks, as standard mail security regulations like URL scanners don't detect any hint of suspected links or attachments in the email. 

The campaign is operated via email accounts hacked earlier, which allows hackers to send mails from authentic user accounts of companies to give a look of authenticity to these mails, and users believe it to be legitimate. As of now, experts are yet to confirm how threat actors are able to get control of these accounts used for sending phishing mails. 

As per experts, these phishing mails contain a voicemail message from the email account admin sending the mail, the target is requested to scan a QR code for listening to the voice mail. The QR codes sent to the victims were also created the same day. An earlier variant of the campaign tried to scam users into opening a malicious link by hiding it in an audio file. 

But, antivirus softwares were able to find and identify the malicious files, which made threat actors turning to QR codes. "While using the QR codes method can more easily bypass email protections, the victim needs to follow many more steps before they reach the point where they could mistakenly give their login credentials to cyber criminals. Applying multi-factor authentication to Microsoft 365 accounts can also help protect login details from being stolen," ZDNet reports.

Credential Phishing and Brute Force Attacks Continue to Surge



Financial and reputational aspects of organizations across the globe are taking a severe hit as they witness advanced email threats from unprecedented email attacks that continue to escalate, as per a recent report by Abnormal Security. Unsuspecting victims fall prey to the schemes which are devised to make the malicious emails land directly into their inboxes evading security mechanisms. 

As threat actors continue to work around various phishing techniques, cyber-attacks via credential phishing and brute force continue to remain effective attack vectors. Advanced email threats such as 'Business Email Compromise' attacks are designed to safely bypass secure email gateways and other conventional security infrastructure allowing the operators to steal in billions each year.  

After gaining access to email accounts, attackers can leverage these accounts to target other associated employees including business partners, vendors, and co-workers. Consequently, it allows them to infiltrate other parts of the compromised organization. Cybercriminals use these credential phishing and brute force attacks to obtain sensitive information such as usernames, passwords, and passphrases. 

The report enlists in its key findings that 5% of all organizations fell prey to brute force attacks in early June 2021, while 73% of all sophisticated threats were credential phishing attacks. 

Since Q4 2020, business email compromise attacks underwent a rise by 22% whereas 61% of companies witnessed a vendor email compromise attack this quarter. Alongside, the experts also made a prediction that there is a 60% probability of an account takeover attack being successful each week for firms having over 50,000 employees. 

While commenting on the matter, Evan Reiser, CEO, Abnormal Security, said, “Socially-engineered attacks are dramatically rising within enterprises worldwide, creating unprecedented financial and reputational risks. These never-before-seen attacks are becoming more sophisticated with every passing day. They don’t contain indicators of compromise, such as links, attachments, and reputational risks, so they evade secure email gateways and other traditional email infrastructure, landing in inboxes where unsuspecting employees fall victim to their schemes, which include ransomware. To effectively protect against these attacks, we can no longer rely only upon established threat intelligence. To baseline good behavior, we need to look further to comprehensively understand employee and vendor identities and their relationships, all with deep context, including content and tone. Any subtle deviations from this baseline expose the possibility of a threat or attack.” 

Furthermore, the report highlights the rise of impersonation, and how cybercriminals are employing it to trick users into submitting sensitive data. Experts remark that the impersonation of internal systems namely IT Support and IT Help Desk has risen 46% in the last two quarters. 

Socially engineered credential phishing and account takeover attacks are surfacing as a major concern for enterprises worldwide because these attacks could potentially provide the access required to carry out other ransomware and malware-based attacks.

Hacker Uses Credential Phishing to Gain Access Into PayPal Account

 

Analysts from Cofense Phishing Defense Center recently found a unique PayPal credential phishing attack. Phishing is a harmful technique that hackers use to steal sensitive information like banking information, credit card data, usernames, and passwords. The actors pretend to be genuine individuals to lure victims by gaining their trust and stealing their personal information. Even worse, the confidential data stolen through phishing attacks can be used for identity theft, financial theft to gain illegal access into victim accounts, or use this account access to blackmail the victims. 

Because credential phishing is generally conducted through a simple URL link, it is easy to ignore exaggerated or subtle tactics that hackers use to steal credentials from innocent victims. As per the experts, the attack isn't very sophisticated and doesn't seem suspicious. Cybersecurity Analyst Alex Geoghagan said that the email may compel the victim to try finding the solution to the problem quickly. The hacker didn't even bother hiding 'from' email address, which was later identified as not actually being from PayPal. But, the e-mail was very well put together and no one would've thought it as a fraud. 

Alex Geoghagan says "There is a “Help & Contact” link, as well as an (ironic) “Learn to identify Phishing” link in the body of the email, both leading to authentic PayPal links. Beyond the first clue in the sender email address, when hovering over the button labeled “Confirm Your Account,” it does not lead to a PayPal URL. It instead leads to a URL at direct[.]lc[.]chat. A user familiar with PayPal may notice at this point that they are being taken to a domain outside of PayPal, while the legitimate PayPal live chat is hosted within the PayPal domain and requires that you log in to use it." 

After a fake live chat has been accessed, hacker uses automated scripts to start communication with the victims and tries to steal user data, e-mail address, credit card information etc. In other words, hacker takes this information to appear as genuine and store enough information for authentication. Once the information is acquired, hacker tries to steal victim's PayPal credentials. After that, a verification code is sent to target via SMS to make him think an authorised person has access to his device. "This attack demonstrates the complexity of phishing attacks that go beyond the typical “Forms” page or spoofed login. In this case, a carefully crafted email appears to be legitimate until a recipient dives into the headers and links, which is something your average user will most likely not do," says Alex Geoghagan.
