Lazarus Exploits Windows Zero-Day to Gain SYSTEM Access and Deploy Backdoor
Lazarus Group exploits Windows zero-day to deploy Troy backdoor against defense firms.
The Lazarus Group, a North Korean state-sponsored threat actor, has exploited a newly patched Windows zero-day vulnerability (CVE-2026-68820) in an ongoing campaign dubbed Operation Dream Job. This campaign targets defense and aerospace companies in France, Germany, Brazil, and India, using social engineering with fake job offers to deliver a new backdoor named Troy, granting them SYSTEM access.

The lesson from this incident
Full lessonThe Lazarus Group leveraged an unpatched Windows zero-day vulnerability (CVE-2026-68820) combined with social engineering tactics — fake job offers targeting defense and aerospace professionals — to deploy a custom backdoor named Troy with full SYSTEM-level privileges. This attack illustrates a dangerous dual vector: technical exploitation of an unpatched OS vulnerability paired with human manipulation, making it significantly harder to defend against with purely technical controls. The targeting of high-value sectors like defense and aerospace in multiple countries signals a coordinated, state-sponsored espionage campaign with serious national security implications. Organizations that lack rapid patch deployment capabilities and employee social engineering awareness training are particularly exposed to this type of sophisticated, layered attack.
