The FBI is investigating Matt Weaver, a third-year business student at California State University San Marcos, for stealing approximately 700 students' user IDs and passwords in order to alter the results of an election for student body president.

Weaver had been arrested and jailed on March 15 on suspicion of election fraud, unlawful access to a computer or database, and identity theft, but posted $50,000 bail the following day and wasn't charged with a crime.

"On Tuesday, university spokeswoman Margaret Lutz-Chantung confirmed that the school was working with the FBI, but declined further comment on the allegations against Weaver," writes North County Times' Teri Figueroa. "She did say, however, that the university had locked down the 700 affected accounts and warned the victims their accounts had been compromised."

"Cal State San Marcos authorities were alerted to possible voter tampering in mid-March after a network administrator noticed suspicious activity on a university computer," writes Threatpost's Anne Saita. "Campus police later found Weaver logged into that school computer and 'in possession of a device that can be used to steal computer passwords' -- a keystroke logger."

"The university said the incident forced them to cancel the mid-March student election and start from scratch," reports. "The election has been rescheduled for May right before final exams."
