What happened when a fired programmer's logic bomb erased an insurance company's database in 1985?

In 1985, a programmer at an insurance company in Fort Worth, Texas, planted a logic bomb within the company’s human resources system. This malicious code was designed to remain dormant until a specific condition was met. When the programmer was fired and his name was subsequently deleted from the company’s employee database, the logic bomb was triggered, resulting in the erasure of the entire database.1
