A popular Chrome VPN extension, FreeVPN.One, with over 100,000 installs has transformed into spyware. Initially legitimate, the extension began capturing screenshots of users' online activities and collecting sensitive information after an update in April 2025. The spyware operates covertly, automatically taking screenshots of every webpage visited and uploading them to an attacker-controlled domain. It also exfiltrates device and location data at installation and startup. The extension's developer provided evasive responses when confronted, claiming the feature was for background scanning of suspicious domains. This incident highlights the potential risks associated with VPN services and the importance of scrutinizing even seemingly trustworthy browser extensions.

A campaign targeting the Google Chrome Web Store has deployed over 100 malicious browser extensions masquerading as legitimate tools like VPNs, AI assistants, and crypto utilities. These extensions, while offering some promised functionality, secretly connect to threat actor infrastructure to steal user information and execute remote scripts. They can modify network traffic, deliver ads, perform redirections, and act as proxies. The campaign, discovered by DomainTools researchers, involves numerous fake domains promoting these tools. The extensions request permissions that enable cookie theft, DOM-based phishing, and dynamic script injection. Risks include account hijacking, data theft, and browsing activity monitoring. Some extensions remain on the Chrome Web Store despite Google's removal efforts.
