Fake Avast Website Steals Users’ Credit Card Information

A phishing scam is targeting French-speaking users in Europe by impersonating Avast antivirus software. Victims are lured to a fraudulent website that mimics Avast's official portal, where they are tricked into providing credit card details due to a fabricated €499.99 charge and promises of a refund. The scam uses realistic branding, dynamic JavaScript for urgency, and live chat features to collect personal information. Users are asked to select refund reasons and submit their personal details, after which they are prompted for credit card information. The scam employs the Luhn algorithm to validate card numbers and displays a fake confirmation message after data submission. Key red flags include dynamic dates, tight deadlines, requests for full card re-entry, and suspicious live chat interactions. Avast has warned users about these scams and encourages reporting to authorities.

Hackers Are Using Fake Invitations to Take Over Your PC

Cybercriminals are sending counterfeit email invitations that, when clicked, install a backdoor on the victim's computer, allowing hackers full control. The scam often involves downloading a file named “invites.msi,” which is a Windows Installer package. This file can install ScreenConnect, a legitimate remote support tool that can be exploited by attackers to monitor screens, access files, and deploy additional malware. Many security engines fail to flag this software as malicious, making it difficult to detect. If someone suspects they have fallen victim to this scam, they should disconnect from the internet, check for and uninstall any remote management software, run a comprehensive antivirus scan, change passwords for critical accounts, enable two-factor authentication, inform their IT department if applicable, and consider performing a full Windows reset. The scam originated from a compromised email account, which was used to send the malicious link to contacts. Implementing two-factor authentication and using a password manager can help prevent such incidents. Users should be cautious of any email invitations that require downloading and running installer files.

Exit Windows S Mode Easily

Windows S Mode is a restricted version of Windows designed for entry-level devices, allowing only apps from the Microsoft Store to enhance security and performance. Users may find it limiting if they need software not available in the Store, such as gaming platforms or professional tools. Exiting S Mode is done through the Microsoft Store by searching for "Switch out of S Mode," clicking "Get" or "Install," confirming the switch, and waiting for the process to complete. This change is permanent, and users cannot revert back without a full reset or reinstallation of Windows. Important considerations before switching include ensuring a stable internet connection, checking the Windows edition, backing up data, and understanding the security risks involved. Common issues during the process include the missing option to switch and installation failures, which can often be resolved by restarting the PC or checking the internet connection. After leaving S Mode, users can install applications from outside the Microsoft Store but must be cautious about security.

Fake Zoom meeting “update” silently installs surveillance software

A deceptive website, uswebzoomus[.]com/zoom/, poses as a Zoom meeting platform and installs surveillance software on Windows devices without user consent. The software is a covert version of Teramind, a commercial monitoring tool. The site creates a fake Zoom waiting room experience, complete with scripted participants and background audio, to trick users into downloading a malicious file named zoomagentx64s-i(_941afee582cc71135202939296679e229dd7cced) (1).msi. This file is preconfigured to connect to an attacker-controlled Teramind server and operates in stealth mode, leaving minimal traces on the device. The installation process collects information about the device and is designed to evade detection by security tools. If users suspect they have been affected, they are advised not to open the downloaded file, check for its installation, and change passwords from a clean device.

Fake Huorong Site Delivers ValleyRAT Backdoor in Targeted Malware Campaign

A cyber operation is targeting users of Huorong Security antivirus software through a typosquatted domain, huoronga[.]com, which mimics the legitimate site huorong.cn. Users who mistakenly visit the counterfeit site may download a file named BR火绒445[.]zip, which contains a trojanized installer that leads to the installation of ValleyRAT, a remote access trojan. The malware employs various techniques to evade detection, including using an intermediary domain for downloads, creating Windows Defender exclusions, and establishing a scheduled task for persistence. The backdoor facilitates activities such as keylogging and credential access while disguising its operations within legitimate processes like rundll32.exe. Attribution points to the Silver Fox APT group, and there has been a significant increase in ValleyRAT samples documented in recent months. Security measures include ensuring software downloads are from the official site and monitoring for specific malicious activities.
