2 CVEs attributed

UNC6748 targets users in Saudi Arabia through a fake Snapchat website, employing a backdoor known as GHOSTKNIFE for data exfiltration. Their exploitation process initially featured basic obfuscation, which evolved to include anti-debugging measures. The actor primarily leveraged CVE-2025-31277 and CVE-2026-20700 for RCE exploits, but exhibited inconsistencies in exploit support for different iOS versions. Additionally, UNC6748's delivery mechanisms incorporated session storage checks to manage infection attempts.
