Cyberspies use Google Chrome extension to steal emails undetected
A North Korean-backed threat group tracked as Kimsuky is using a malicious browser extension to steal emails from Google Chrome or Microsoft Edge users reading their webmail.
The extension, dubbed SHARPEXT by Volexity researchers who spotted this campaign in September, supports three Chromium-based web browsers (Chrome, Edge, and Whale) and can steal mail from Gmail and AOL accounts.
