US EditionRussians Posing as Signal Support to Launch Phishing Raids
Thousands of Signal and WhatsApp accounts linked to officials and journalists were compromised using social engineering, not encryption breaches, FBI and CISA reported.
- On March 20, 2026, Reuters reported hackers linked to Russian intelligence targeted Signal and WhatsApp users, with the FBI and CISA warning thousands of accounts were compromised.
- Using social-engineering, attackers posed as support on Signal and WhatsApp, sending verification links and urging victims to hand over credentials or 2FA codes.
- After account takeover, attackers could read and send messages and harvest contact lists to conduct follow-on phishing campaigns, while deploying malware and evolving techniques to expand access beyond compromised accounts.
- Last Friday, the FBI and CISA issued a joint advisory mirroring Dutch intelligence warnings that government employees, soldiers, civil servants, and journalists were targeted, urging victims to report incidents to IC3 or local FBI offices.
- Agencies recommended users strengthen personal cybersecurity practices, scrutinize links before clicking, and treat suspicious messages and unknown contacts with caution to reduce compromise risk.
