From a news story:
"It seems like every time we have something good, scammers can find a way to cause a problem. If you travel the toll roads, watch out.
Con artists posing as E-Z Pass officials are using email in an attempt to collect “unpaid” tolls. The emails, however, carry viruses that infect your computer and can set you up to become a victim of identity theft.
Here’s the way it works: You receive an email that appears to be from E-Z Pass. The correct colors and logo are used. The message says you ignored previous bills for unpaid tolls and you are urged to pay immediately. You can do this by downloading an attached “invoice.”
If you download the attachment, it appears that nothing has happened – but that is not the case. Instead you just downloaded a virus to your computer. These viruses scan your machine for personal and banking information, which opens you up to the threat of ID theft."
Forewarned is forearmed.
