Cybercriminals are exploiting a legacy feature in Windows File Explorer, specifically the WebDAV protocol, to distribute malware and bypass traditional security measures. Despite Microsoft deprecating native WebDAV support in November 2023, it remains active on many systems. Attackers use WebDAV to deceive victims into executing malicious payloads by sending links that connect File Explorer directly to remote servers, avoiding web browsers and their security warnings. They employ methods such as direct linking, URL shortcut files, and LNK shortcut files to deliver exploits. The primary objective of these campaigns, which surged in late 2024, is to deploy Remote Access Trojans (RATs), with 87% of Active Threat Reports involving multiple RATs like XWorm RAT, Async RAT, and DcRAT. These campaigns predominantly target corporate networks in Europe, with many phishing emails written in German and English. Attackers use short-lived WebDAV servers hosted on Cloudflare Tunnel demo accounts to obscure their infrastructure. Security analysts are advised to monitor unusual network activity from Windows Explorer and educate users to verify addresses in File Explorer.

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.

Meta will close the Messenger website in April, redirecting users to the messaging feature on Facebook. Users' chat history will be preserved during this transition. The Messenger desktop application for Windows and Mac has already been discontinued. Users can still access Messenger through the mobile application. Meta aims to simplify its services by reducing standalone platforms. Messenger was first introduced as Facebook Chat in 2008, separated in 2014, and will reunite with Facebook in 2023.
