Wichita City Hall’s e-mail system was among scores of major e-mail systems infected Thursday by a worm that fanned out messages to people’s contacts.
The messages usually had the subject line “here you have.” It includes a link to a PDF document that, if opened, led to a site where the message recipient could also be infected with the worm.
The first message out of city hall happened around 1 p.m. Thursday, according to Kevin Norman, the city’s IT operations manager. The worm ground the city’s system to a halt, and IT officials shut the system down entirely around 2:30 p.m. The worm circumvented the city’s anti-virus programs — as it did at major corporations across the nation.
Norman said officials worked through the evening installing updated anti-virus programs and hunting down malicious e-mails. The city’s server went back online around 3 a.m., Norman said.
At least one e-mail account at Derby City Hall was also infected.
