Former Developer Sentenced to Four Years for Sabotaging Ohio Employer with Kill-Switch Malware

Davis Lu, a former developer, got slapped with a four-year prison sentence in March 2025 for planting a kill-switch malware in his Ohio employer's systems back in 2019, causing over $100K in damages. Talk about a revenge plot gone wrong—this is why you don't mess with corporate code on your way out.

The malware was designed to activate after Lu left the company, wiping critical data and disrupting operations. FBI got involved, traced it back to him, and now he's serving time. Insider threats are no joke—this case highlights why companies need to beef up their security protocols, especially with disgruntled ex-employees.
