CISA Warns of Invasive Spyware Targeting Mobile Messaging Apps
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) recently issued an alert regarding the heightened threat of spyware and remote access trojans (RATs) targeting mobile messaging applications. Cyber actors are using advanced social engineering and targeting tactics to exploit vulnerabilities, gaining unauthorized access to users’ devices and messaging apps.
Key Details
