Using a clever bit of social engineering, hackers in in Grand Forks, North Dakota have placed tickets on vehicles citing fake traffic violations and referring the "offender" to a website that claimed to have photos of the alleged violation, but which actually tricked users into downloading a virus.
"According to internet security watchdog The SANS Institute, the website then had photos of cars in various car parks around Grand Forks and instructed users to download a tool bar to find photos of their own vehicle.
But the tool bar was actually an executable file which installed a Trojan virus that then displayed a fake security alert when the PC was rebooted. The fake alert then prompted the user to install fake anti-virus software."
It still amazes me how easily we are duped into falling for these tricks... clever though!
