The Russian threat actor APT28 has launched a new spear-phishing campaign targeting Ukraine and its allies, deploying a previously undocumented malware suite called PRISMEX, which utilizes advanced steganography, COM hijacking, and legitimate cloud service abuse for command-and-control.
The key insight for a cybersecurity professional is that APT28's new spear-phishing campaign employs the PRISMEX malware suite, which uses advanced techniques like steganography, COM hijacking, and cloud service abuse for command-and-control. This highlights the need for enhanced threat intelligence and defensive measures against sophisticated methods that leverage legitimate services, emphasizing the importance of monitoring for unusual cloud activity and integrating advanced detection mechanisms within security operations.
