Ars Technica reported this week that a group of students in Southern California were caught connecting to the school’s computers and changing their grades. Apparently they used an old fashion method to gain access. When the teachers were not looking, they connected key loggers to their computers. These devices can be very small and connect to the USB / keyboard ports on the back of the computer. They capture everything that is typed in and store it in their memory. After they are retrieved, the perpetrator can determine everything that has been typed in, including passwords. If you are a teacher, it’s one more thing you need to check for, especially if you have tech savvy students.
