The StrikeShark campaign utilizes a novel malware family named SharkLoader to deploy Cobalt Strike Beacons across various global sectors. Threat actors gain initial access by exploiting known vulnerabilities in public-facing applications or distributing custom droppers disguised as legitimate software. SharkLoader employs advanced evasion techniques, including Perfect DLL Hijacking and extensive API hooking, to bypass loader locks and conceal its execution in memory.
