If you ever wonder why I get worked up about computer security it is stories of the authorities with little or no understanding chasing after poor innocents stuck with poor software and unprotected computer systems
Cringley posted a couple of clogs - the first
here and then a follow up
here on the Connecticut Julia Amero case where they went after a school teacher after the PC she was using exploded with pop ups of porn.
Amero's "crime": In October 2004, the substitute teacher from Norwich, Conn., was surfing the Net on a computer inside a middle school classroom when porn ads began popping up all over the screen. She didn't turn the computer off, because school officials expressly told her not to. Someone reported the incident, and Amero was charged with four counts of endangering minors. In January 2007, a jury convicted Amero of surfing XXX sites in the classroom.
You can see the summary
here (pdf) which details the findings from a group of volunteer security experts reviewing a Disk Image (but refused access to the firewall server logs)
The PC itself was described as:
Windows 98 PC described by another security wonk as a "pile of living dog **** with absolutely no protection on it"
Familiar story.......thanks to Sunbelt software and their
CEO Alex Eckelberry she had the charge "reduced" and just paid a fine but the state refused to admit any wrongdoing.
Be warned even if the company or school or office advice is to leave the PC on it might just be better to turn it off rather than have exploding pop up windows appearing on the PC that are deemed to be your fault. I wonder who it was that originally complained. I have seen this on friends PC's, on home PC's and elsewhere and even with skilled technical resources it can be next to impossible to get rid of this level of infection.
