North Korean threat group Kimsuky isn't slowing down - and their latest HTTPSpy campaign is a good reminder of how sophisticated social engineering has become.
In their most recent activity (observed through March and April 2026), Kimsuky masqueraded as legitimate B2B software installers and a spoofed Cisco Webex troubleshooting page to get victims to run malicious droppers.
Once inside, HTTPSpy hands the attacker full remote control: command execution, file exfiltration, screenshots, process injection, and clean self-deletion. They also wired in stolen meeting schedules to redirect targets into real Webex rooms, making the lure look entirely authentic.
What makes this campaign notable isn't just the malware - it's the operational discipline. Kimsuky is using legitimate infrastructure (Visual Studio Code Remote Tunnels, Cloudflare Quick Tunnels, DWAgent) to blend covert access into normal IT operations. No noisy C2 traffic. No obvious red flags.
For defenders, the takeaway is clear: scrutinize your remote access channels, harden against script-based droppers, and keep a close eye on certificate stores and GPKI paths. The attack surface they're targeting isn't exotic, it's the trust you extend to everyday tools.
