CISA, FBI Warn of Phishing Campaign Targeting Messaging App Users

**Phishing campaign targets messaging apps:** CISA and the FBI warn of a widespread phishing campaign—attributed to actors linked to Russian intelligence—that uses social engineering (fake support messages, requests for verification codes, malicious links) to hijack accounts on commercial messaging apps, bypassing end-to-end encryption by compromising users rather than exploiting software vulnerabilities; thousands of accounts have been affected and attackers may deploy malware in some cases.
