Denton High School Data Breach (2013)

18-year-old Marshall Williams, a student of the Denton High School in Denton, Texas, has been arrested and charged with hacking into the school’s systems on two separate occasions. According to Fox 4, Williams hacked into the high school’s secure Wi-Fi network – which stores test results, employee records, a master key list and building alarm codes – in March and April. In addition, he used school printers to print out the stolen security codes and test results. Investigators traced the breach back to the student’s phone based on logs and an IP address. Surveillance videos showed that he was in the Wi-Fi area during the breaches. Arrest documents reveal that Williams wanted to get back at the school after an English teacher refused to grade a report he wrote based on a trip to a gun show. The teacher argued that the report came shortly after the Newtown, Connecticut, massacre. However, he later apologized.
