Security researchers discovered 17 malicious Firefox extensions and 5 Chrome extensions that spy on users and hijack accounts. The Firefox extensions use steganography to hide JavaScript code inside image files, making detection harder. They had over 50,000 downloads combined and include names like ad blocker, Amazon Prime history, and YouTube download. The Chrome extensions impersonate Workday and NetSuite to steal authentication tokens and enable account takeover. Most have been removed from official stores, but the incident highlights ongoing risks with browser extensions even from official sources.
