According to a message from CISA on Monday, November 24th 2025, Messaging apps are being targeted by malicious spyware actors using commercial spyware programs.

Several threat actors have used “sophisticated targeting and social engineering techniques to deliver spyware and gain unauthorized access to a victim’s messaging app,” which then lets them deploy additional malware and acquire deeper access to the target’s phone, CISA said in an alert.

The National Security Agency (NSA) is joining the Cybersecurity and Infrastructure Security Agency (CISA) and others to release the Cybersecurity Information Sheet (CSI), “Bulletproof Defense: Mitigating Risks from Bulletproof Hosting Providers,” to provide internet service providers (ISPs) and network defenders recommendations to mitigate potential cybercriminal activity enabled by bulletproof hosting (BPH) providers.
