What happened

Proofpoint RSS listings highlight active and emerging cyber threats, including indirect prompt injection, Russian cyber-espionage targeting email accounts, exploitation of Exchange and Zimbra vulnerabilities, ransomware enabled by AI, and repeated ransom demands. The feed contains threat reporting and press releases rather than a single incident; several entries describe nation-state activity and actively exploited or zero-day flaws.
