Universities often need to have a number of computers in classrooms ready for faculty and staff to use for presentations and Internet access , which can be a security challenge . Carleton University is the latest to find that out when a regular inspection discovered USB keylogging devices had been plugged into six classroom PCs . The computers themselves can ’ t store data , said Beth Gorham , Carleton ’ s manager of public affairs , so there was no risk of university data being captured Attack.Databreach . However , the PCs are connected to the campus network so keyloggers would be able to capture Attack.Databreach login information . As a result all staff , faculty , contract instructors and teaching assistants have been ordered to change their passwords . In addition , the university has recommended all students do the same “ out of an abundance of caution. ” “ We have no indication that any personal information has been obtained Attack.Databreach , ” she said . Discovery of the devices was made a week ago during a regular inspection of classroom devices by the instructional media services staff , Gorham said . Until now because presenters use USB memory sticks for presentations the USB ports of the computers hadn ’ t been locked , Gorham said . However , she said , since the discovery “ those computers and other were secured [ with locks ] so this can ’ t happen again. ” And as a result of the incident classroom inspections have been stepped up .
