"Bounced Mail" Warning from the "Support Team"
Please ignore any email warning you that your account has been compromised and asking y ou to run an attached program; it's a ruse to get you to run an attachment which may very well compromise your Windows computer.
Mail from RHPCS will always be identified as coming from me or from one of the other sysadmins personally and we would never ask you to run anything from an attachment.
Here's an example of the sort of message that's making the rounds:
Dear user of math.mcmaster.ca,
Your account has been used to send a huge amount of unsolicited e-mail messages during this week.
Most likely your computer had been compromised and now runs a trojan proxy server.
Please follow our instructions in order to keep your computer safe.
Have a nice day,
The math.mcmaster.ca support team.
