The U.S. Cybersecurity and Infrastructure Security Agency (CISA) is giving federal agencies until Sunday to patch a vulnerability in Cisco Unified Communications Manager Server that is being actively exploited. [...]

The FBI and CISA have updated their March warning about Russian intelligence phishing Signal accounts, and the operators have added a step: they now coax targets into handing over their Signal Backup Recovery Key. Hand it over once, and the attacker can restore the account's backup, read the private and group message history, and take over the account. Worse, the key keeps working.
