EXTENSION BANNED FOR STEALING AI CHATS RETURNS TO CHROME STORE, RESUMES MALICIOUS ACTIVITIES

Summary from the TLDR InfoSec newsletter

A malicious Chrome extension named "AI Sidebar with DeepSeek ChatGPT Claude and more" has bypassed a previous Web Store ban and returned with a new fraudulent monetization scheme. Netskope Threat Labs discovered that version 1.7.3.0 contains a script that farms affiliate commissions through an AI video platform during every update and overwrites the uninstall URL to ensure even removing the extension generates a referral payout. Defenders should immediately block and remove this extension, classified as Trojan.GenericFCA.Script.37952, which falsely masquerades as an official DeepSeek AI product to deceive users.
