Attack Vector: Supply chain attack via compromised software update.

Timeline: Attackers compromised the vendor's update infrastructure and trojanized a legitimate software update. When the update was automatically deployed across the organization, it established command-and-control communication with attacker infrastructure. The malware used privilege escalation to gain system-level access and installed persistence mechanisms. The breach was discovered during a threat hunt based on external intelligence about the compromised vendor.

Lesson: Supply chain attacks are difficult to prevent since they abuse trusted relationships. Defenses include vendor security assessments, network monitoring for unusual behavior even from trusted software, threat intelligence integration, and proactive threat hunting. Update staging environments and gradual rollouts can also limit impact.
