SideWinder’s Silent War Using Old Exploits on New Targets

SideWinder is back with a highly targeted cyberattack campaign across South Asia, aiming at government and military institutions in countries like Sri Lanka, Bangladesh, and Pakistan. Using old but still dangerous Microsoft Office flaws, the attackers deliver stealthy, multi-stage malware that steals credentials and maintains access for long-term espionage. What makes this campaign stand out is how SideWinder mixes techniques like shellcode-based loaders, DLL sideloading, and fast-changing command-and-control domains to stay under the radar.
