Users of Chromium-based browsers, including Google Chrome, Brave, and Opera, are experiencing deceptive pop-ups that falsely claim a "Critical Update Required" or "Update available." These notifications are part of a scam designed to trick users into downloading malware disguised as software updates. Clicking on these prompts can lead to the download of harmful scripts, such as .vbs or .exe files, which traditional antivirus software often fails to detect. The issue is linked to compromised browser extensions that fetch malicious scripts from external servers. A specific extension, QuickLens – Search Screen with Google Lens, has been identified as a source of these pop-ups and has been removed from the Web Store. Other extensions, like “Enable Right Click & Copy Smart Unlock + OCR,” have also been implicated despite their popularity. Users are advised not to click on any links or run downloaded files and to check their browser settings for legitimate updates, as well as to audit and disable suspicious extensions.

Securonix Threat Research has identified a cyber campaign called SMOKE#SCREEN that uses deceptive tactics to trick users into installing weaponized versions of ScreenConnect, a legitimate remote monitoring software. The attackers disguise their malicious intent with fake update notifications for applications like Zoom and Adobe, as well as counterfeit business documents. This campaign allows attackers to gain persistent remote access to victims' systems, disable security protections, and exploit trusted services like Dropbox and Cloudflare for delivering malicious payloads. Victims have been reported on both Windows and macOS platforms. Businesses are advised to verify updates through official channels and train staff on the risks of unexpected software installations.

A newly identified Android malware called BeatBanker disguises itself as a Starlink application on fake Google Play Store websites. It functions as a banking trojan and includes Monero mining capabilities, allowing it to steal credentials and manipulate cryptocurrency transactions. Researchers at Kaspersky traced BeatBanker to campaigns targeting users in Brazil. The latest version uses the BTMOB RAT for remote access, enabling keylogging, screen recording, camera access, GPS tracking, and credential capture. BeatBanker is distributed as an APK file that decrypts and loads hidden code into memory, conducting environment checks before activation. It presents a fake Play Store update screen to trick users into granting permissions for additional payloads. To avoid detection, it delays malicious operations and plays a nearly inaudible MP3 file to maintain persistent activity. The malware uses a modified version of the XMRig miner to mine Monero on Android devices, connecting to mining pools through encrypted TLS connections. It can start or stop mining based on device conditions and uses Firebase Cloud Messaging to relay device information to its command-and-control server. Currently, BeatBanker infections have only been observed in Brazil, but there are concerns about its potential spread. Users are advised to avoid side-loading APKs from untrusted sources and to review app permissions regularly.

A new wave of ClickFix attacks has emerged, using fake Windows Update screens and PNG image steganography to deploy infostealing malware like LummaC2 and Rhadamanthys. The attacks trick users into executing a command by pressing Win+R and pasting a command copied to their clipboard. Attackers have shifted from using “Human Verification” lures to more convincing full-screen fake Windows Update screens. The fake update prompts users to run a command that initiates mshta.exe with a URL containing a hex-encoded IP address, leading to the download of obfuscated PowerShell and .NET loaders. A notable feature of the campaign is the use of a .NET steganographic loader that hides shellcode within the pixel data of a PNG image, which is decrypted and reconstructed in memory. The shellcode is Donut-packed and injected into processes like explorer.exe using standard Windows APIs. Huntress has been monitoring these ClickFix clusters since early October, noting the use of the IP address 141.98.80[.]175 and various paths for the initial mshta.exe stage, with subsequent PowerShell stages hosted on domains linked to the same infrastructure. Despite the disruption of Rhadamanthys’ infrastructure in mid-November, active domains continue to serve the ClickFix lure, although the Rhadamanthys payload appears to be unavailable. To mitigate the attack, disabling the Windows Run box through Group Policy or registry settings is recommended, along with monitoring for suspicious activity involving explorer.exe. User education is critical, emphasizing that legitimate processes will not require pasting commands into the Run prompt. Analysts can check the RunMRU registry key to investigate potential ClickFix abuse.
