A Russian Exploit writer and underground Hacker who goes by the handle " fil9 " put up an Android Firefox Zero-Day Exploit for Sale in an open Exploit Market. Author claims a Zero Day vulnerability in Firefox for Android, which works on Firefox versions 23/24/26 (Nightly). The advertisement was spotted by Joshua, Malware Intelligence Analyst at Malwarebytes. Hacker Selling exploit with a starting price of $460 only. According to the proof of concept video uploaded by the Hacker, the exploit forces the mobile Firefox browser to download and execute a malicious app, on just visiting a malicious link only. What’s worrisome is that many major websites are compromised frequently and a large number of visitors of those hacked sites can fall victim to this attack. " The biggest problem in this situation is that Firefox automatically executes certain known files once they’re downloaded, and doesn’t give users an option to disable this. Without some sort of ...

A highly popular top-tier app in Apple's Mac App Store that's designed to protect its users from adware and malware threats has been, ironically, found surreptitiously stealing their browsing history without their consent, and sending it to a server in China. What's more concerning? Even after Apple was warned a month ago, the company did not take any action against the app. The app in question is "Adware Doctor," the Mac App Store No. 1 paid utility and also ranked as the fourth most popular paid app on the store, which sells for $4.99 and markets itself to be the "best app" to prevent "malware and malicious files from infecting your Mac." However, a security researcher with the @privacyis1st Twitter handle detected Adware Doctor's suspicious spyware-like behavior almost a month ago and also uploaded a proof-of-concept video demonstration of how the user's browser history is exfiltrated. The researcher informed Apple about...

Apple has removed almost all popular security apps offered by well-known cyber-security vendor Trend Micro from its official Mac App Store after they were caught stealing users' sensitive data without their consent. The controversial apps in question include Dr Cleaner, Dr Cleaner Pro, Dr Antivirus, Dr Unarchiver, App Uninstall, Dr. Battery, and Duplicate Finder for Mac computers. The apps were removed just two days after Apple kicked out another popular "Adware Doctor" application for collecting and sending browser history data from users' Safari, Chrome, and Firefox to a server in China. "This was a one-time data collection, done for security purposes (to analyze whether a user had recently encountered adware or other threats, and thus to improve the product & service)," Trend Micro argued. The suspicious behavior of Trend Micro apps was initially reported by a user on the Malwarebytes forum in December 2017, which was last weekend re-con...

Some websites have found using a simple yet effective technique to keep their cryptocurrency mining javascript secretly running in the background even when you close your web browser. Due to the recent surge in cryptocurrency prices, hackers and even legitimate website administrators are increasingly using JavaScript-based cryptocurrency miners to monetize by levying the CPU power of their visitor's PC to mine Bitcoin or other cryptocurrencies. After the world's most popular torrent download website, The Pirate Bay , caught secretly  using Coinhive , a browser-based cryptocurrency miner service, on its site last month, thousands of other websites also started using the service as an alternative monetization model to banner ads. However, websites using such crypto-miner services can mine cryptocurrencies as long as you're on their site. Once you close the browser window, they lost access to your processor and associated resources, which eventually stops mining. Un...

The Computer Emergency Response Team of Ukraine (CERT-UA) has  cautioned  of a new set of spear-phishing attacks exploiting the "Follina" flaw in the Windows operating system to deploy password-stealing malware. Attributing the intrusions to a Russian nation-state group tracked as APT28 (aka Fancy Bear or Sofacy), the agency said the attacks commence with a lure document titled "Nuclear Terrorism A Very Real Threat.rtf" that, when opened, exploits the recently disclosed vulnerability to download and execute a malware called CredoMap. Follina ( CVE-2022-30190 , CVSS score: 7.8), which concerns a case of remote code execution affecting the Windows Support Diagnostic Tool (MSDT), was addressed by Microsoft on June 14, as part of its Patch Tuesday updates , but not before it was subjected to widespread zero-day exploit activity by numerous threat actors. According to an independent report published by Malwarebytes,  CredoMap  is a variant of the .NET-based credenti...

Another week in cybersecurity. Another week of "you've got to be kidding me." Attackers were busy. Defenders were busy. And somewhere in the middle, a whole lot of people had a very bad Monday morning. That's kind of just how it goes now. The good news? There were some actual wins this week. Real ones. The kind where the good guys showed up, did the work, and made a dent. It doesn't always happen, so when it does, it's worth noting. The bad news? For every win, there's a fresh headache waiting right behind it. New tricks, old tricks dressed up in new clothes, and a few things that'll make you want to go touch grass and never log back in. But you will. We all do. So here's everything that mattered this week — the wins, the warnings, and the stuff you really shouldn't ignore. ⚡ Threat of the Week Tycoon 2FA and LeakBase Operations Dismantled — The infrastructure hosting the Tycoon2FA service, which Europol said was among the largest advers...

A new malvertising campaign has been observed distributing an updated version of a macOS stealer malware called  Atomic Stealer  (or AMOS), indicating that it’s being actively maintained by its author. An off-the-shelf Golang malware available for $1,000 per month, Atomic Stealer  first came  to light in April 2023. Shortly after that, new variants with an expanded set of information-gathering features were detected in the wild, targeting gamers and cryptocurrency users. Malvertising via Google Ads has been observed as the primary distribution vector in which users searching for popular software, legitimate or cracked, on search engines are shown bogus ads that direct to websites hosting rogue installers. The latest campaign involves the use of a fraudulent website for TradingView, prominently featuring three buttons to download the software for Windows, macOS, and Linux operating systems. “Both the Windows and Linux buttons point to an MSIX installer hosted on...

Today everybody wants to know — Who visited my Facebook profile?, Who unfriended me from the Facebook Friend list?, Who saw my Facebook posts?, and many other features that isn't provided by Facebook by default. So most Facebook users try to find out a software and fall victim to one that promises to accomplish their desired task. Hackers make use of this weakness and often design malicious programs in order to victimize broad audience. Following I am going to disclose the realities behind one such software designed cleverly to trick Facebook users to make them believe it is genuine. UnfriendAlert , a free application that notifies you whenever someone removes you from the Facebook friend list, has been found collecting its users' Facebook credentials. UnfriendAlert Stealing your Facebook Credentials: Security researchers at Malwarebytes have warned users of the UnfriendAlert app saying that the notorious app asks users to login with their Facebook ...

A now-patched security flaw in the Microsoft Defender SmartScreen has been exploited as part of a new campaign designed to deliver information stealers such as ACR Stealer, Lumma , and Meduza . Fortinet FortiGuard Labs said it detected the stealer campaign targeting Spain, Thailand, and the U.S. using booby-trapped files that exploit CVE-2024-21412 (CVSS score: 8.1). The high-severity vulnerability allows an attacker to sidestep SmartScreen protection and drop malicious payloads. Microsoft addressed this issue as part of its monthly security updates released in February 2024. "Initially, attackers lure victims into clicking a crafted link to a URL file designed to download an LNK file," security researcher Cara Lin said . "The LNK file then downloads an executable file containing an [HTML Application] script." The HTA file serves as a conduit to decode and decrypt PowerShell code responsible for fetching a decoy PDF file and a shellcode injector that, in tur...

An advanced persistent threat (APT) actor aligned with Chinese state interests has been observed weaponizing the new  zero-day flaw  in Microsoft Office to achieve code execution on affected systems. "TA413 CN APT spotted [in-the-wild] exploiting the Follina zero-day using URLs to deliver ZIP archives which contain Word Documents that use the technique," enterprise security firm Proofpoint  said  in a tweet. "Campaigns impersonate the 'Women Empowerments Desk' of the Central Tibetan Administration and use the domain tibet-gov.web[.]app." TA413  is best known for its campaigns aimed at the Tibetan diaspora to deliver implants such as  Exile RAT  and  Sepulcher  as well as a rogue Firefox browser extension dubbed  FriarFox . The high-severity security flaw, dubbed Follina and tracked as CVE-2022-30190 (CVSS score: 7.8), relates to a case of remote code execution that abuses the "ms-msdt:" protocol URI scheme to execute arbitrary code...

Threat actors are increasingly mimicking legitimate applications like Skype, Adobe Reader, and VLC Player as a means to abuse trust relationships and increase the likelihood of a successful social engineering attack. Other most impersonated legitimate apps by icon include 7-Zip, TeamViewer, CCleaner, Microsoft Edge, Steam, Zoom, and WhatsApp, an analysis from VirusTotal has revealed. "One of the simplest social engineering tricks we've seen involves making a malware sample seem a legitimate program," VirusTotal  said  in a Tuesday report. "The icon of these programs is a critical feature used to convince victims that these programs are legitimate." It's no surprise that threat actors resort to a variety of approaches to compromise endpoints by tricking unwitting users into downloading and running seemingly innocuous executables. This, in turn, is primarily achieved by taking advantage of genuine domains in a bid to get around IP-based firewall defenses...

A very profitable line for mobile malware developers is Android Banking Trojans, which infect phones and steal passwords and other data when victims log onto their online bank accounts. One recent trend is Android malware that attacks users in specific countries, such as European Countries, Brazil and India.  The Antivirus software maker Malwarebytes noticed that a new threat distributed via file sharing sites and alternative markets in the last few months, targets Korean users. Dubbed as ' Android/Trojan . Bank . Wroba ', malware disguises itself as the Google Play Store app and run as a service in the background to monitor events.  " This enables it to capture incoming SMS, monitor installed apps and communicate with a remote server. " According to the researcher, after installation - malware lookup for existence of targeted Banking applications on the device, remove them and download a malicious version to replace. " The malicious v...
