Overview

• Davis Lu, a former software developer at Eaton Corporation, was convicted of intentionally damaging protected computers after a corporate restructuring reduced his responsibilities.
• Lu deployed custom malware, including infinite loops that crashed servers, and deleted coworker profiles to disrupt systems starting in August 2019.
• He created a 'kill switch' named 'IsDLEnabledinAD,' which locked out thousands of employees when his credentials were disabled upon termination in September 2019.
• Investigators discovered Lu's malicious code, named with terms like 'Hakai' (Japanese for 'destruction'), and evidence of his efforts to hide processes and escalate privileges.
• The sabotage caused hundreds of thousands of dollars in damages, and Lu now faces a maximum sentence of 10 years in prison, with sentencing yet to be scheduled.
