Tech Sabotage: Ex-Employee’s Malicious Code Lands Him Four-Year Prison Sentence
Davis Lu, a Houston-based software engineer, turned his employer’s systems into a digital circus act with malicious code. His “IsDLEnabledinAD” kill switch ensured chaos, logging out users worldwide. His antics cost the company dearly, landing him a four-year prison sentence. The lesson? Don’t bite the hand that feeds—or codes.

Hot Take:
When your workplace rage reaches new heights, but instead of flipping tables, you decide to flip the entire company server! Davis Lu, the man with a plan—albeit a dastardly one—has shown us all that sometimes the pen isn’t mightier than the sword, especially if the sword is a piece of malicious code. While most of us just fantasize about sending a salty email, Lu took it to a whole new level. Let’s hope Lu enjoys his new coding gig in the big house, where the only thing he’ll be debugging is his prison cell’s Wi-Fi.
