Dr. Xiaofeng Wang's Disappearance

• Dr. Xiaofeng Wang, a computer science professor at Indiana University Bloomington, disappeared under mysterious circumstances.
• The university removed his profile page, and the FBI raided his home.
• His recent work focused on machine learning security, specifically detecting backdoors in large language models.
• Misconduct allegations were filed against Wang, accusing him of mislabeling the principal investigator for a grant and failing to disclose co-authors.
• It was confirmed by someone in China that he is alive and safe and wasn't disappeared by the government.

Examples of Programmer Sabotage

• Davis Lou: A software developer from Texas who implemented a kill switch in Java after corporate realignment.
  • The kill switch was designed to activate when his name was removed from the Active Directory.
  • It created infinite loops to crash servers, delete coworker profiles, and lock out users.
  • The kill switch was activated on September 9th, 2019, causing his employer to lose hundreds of thousands of dollars.
  • Lou was convicted of criminal sabotage and faces 10 years in prison.
• David Tinsley: Implemented a logic bomb at Siemens.
  • The logic bomb was designed to overload automated spreadsheet software every few months.
  • Siemens would have to pay Tinsley to fix it.
  • Tinsley was caught when he went on vacation, and someone else fixed the issue, revealing the sabotage.
  • He received 6 months in prison and a $7,500 fine.
• Terry Childs: Set up the fiber optic network for the city of San Francisco.
  • Refused to provide passwords to the city, effectively shutting down the city government for 12 days.
  • Initially refused to give up the passwords even after being jailed.
  • Eventually gave up the passwords and was sentenced to four years in prison.
