This fake Windows 11 24H2 update looks perfect, until it avoids antivirus and steals your passwords

Cybercriminals are using sophisticated tactics to deceive users, particularly with a counterfeit website posing as a legitimate Windows 11 update. This site operates under the domain microsoft-update[.]support and is designed to trick individuals into downloading malware that compromises sensitive information. The site is written in French and mimics a genuine cumulative update for Windows 11, version 24H2, featuring a convincing KB article number and a blue download button. The malware is packaged as a Windows update using the WiX Toolset 4.0.0.5512 and is labeled "WindowsUpdate 1.0.0.msi," with properties that suggest it is from Microsoft. At the time of analysis, VirusTotal showed no detections for the malware, which conceals its harmful code within an Electron shell, making it difficult to identify. Users are advised to download updates directly through the Windows Settings app or from Microsoft's official support hub.

Research company claims spyware posing as Israel’s Red Alert Android app targeting users

Acronis Threat Research Unit (TRU) has uncovered a cyber espionage campaign targeting Israeli civilians through a fake version of the Red Alert app. The attack begins with a deceptive text message claiming to be from Israel's Home Front Command, urging users to download an updated app due to a malfunction. The fraudulent app closely resembles the legitimate Red Alert app but contains malware that collects sensitive personal information, including messages, contacts, location data, and device account details. This data is stored locally and then transmitted to a remote server controlled by the attackers. The hackers use certificate spoofing and other techniques to bypass Android's security measures, making the malicious app appear legitimate. Cybersecurity experts recommend that Israeli users take precautions to protect their personal information.

Fake Xeno and Roblox Utilities Used to Install Windows RAT, Microsoft Warns

Cybersecurity experts at Microsoft Threat Intelligence have identified a trend where attackers distribute counterfeit gaming tools that install a remote access trojan (RAT) on users' systems. These trojanized executables, such as Xeno.exe or RobloxPlayerBeta.exe, are shared through browsers and chat platforms. The initial executable acts as a downloader, installing a portable Java runtime environment and launching a harmful Java archive, jd-gui.jar. Attackers use built-in Windows tools to execute commands via PowerShell and exploit trusted system binaries, minimizing detection risk. The embedded PowerShell script connects to remote locations, downloads an executable as update.exe, and executes it. The malware erases evidence of the downloader and modifies Microsoft Defender settings to allow RAT components to function undetected. It establishes persistence through scheduled tasks and a startup script named world.vbs, enabling prolonged access to the compromised device. Microsoft Defender can detect the malware and its behaviors, and organizations are advised to monitor outbound traffic and block identified domains and IP addresses. Users are encouraged to scrutinize Microsoft Defender exclusions and scheduled tasks for irregularities and remain cautious about downloading tools from unofficial sources.

Unsecured AI apps are leaking personal data of Android users

Many unregulated or inadequately secured AI applications on platforms like the Google Play store pose significant privacy risks to users. A specific Android application, "Video AI Art Generator & Maker," linked to a data leak, compromised 1.5 million user images, over 385,000 videos, and millions of AI-generated media files due to a misconfiguration in a Google Cloud Storage bucket. Another app, IDMerit, exposed sensitive know-your-customer data from users in 25 countries, including full names, addresses, birthdates, IDs, and contact information, totaling a terabyte of data. Both developers addressed the vulnerabilities after being alerted by researchers. However, cybersecurity experts warn that lax security among AI applications is a widespread issue, with 72 percent of analyzed Google Play apps exhibiting security flaws, including the practice of "hardcoding secrets" in their source code.
