Paying bills online? You might be pwned

Online payment system infected with malware? not good.

We take great care to keep your personal information secure. As part of these ongoing efforts, we are notifying you that the computer you use for online bill payment may have been exposed to software that puts the security of your computer’s contents at risk. This letter will help you determine if your computer is actually infected and advise you how to fix the problem and protect yourself against future risk.

The malicious software affects some but not all customers who accessed online bill payment on Tuesday, December 2, 2008. For a limited period of time, some customers were redirected from the authentic bill payment service to another site that may have installed malicious software. Your computer may be infected if all of the following are true:

  • You attempted to access online bill payment between 12:30 a.m. and 10:10 a.m. Eastern time (GMT -5) on Tuesday, December 2, 2008, and
  • You were using a computer with the Windows operating system, and
  • You reached a blank screen rather than the usual bill payment screen when you attempted to navigate to online bill payment, and
  • After reaching the blank screen, your computer’s virus protection program did not tell you via pop-up or other messaging that malicious software was detected and quarantined.

If all four of the conditions above are true, your computer may be infected. [marketing blurb about an AV vendor that was quick enough to cash in]

CheckFree will never ask for your password via email or via phone.  If you ever receive an email requesting your password, do not respond and delete the email immediately.

We value your business and your trust, and we apologize for any inconvenience this incident has caused.
Thank you,

Art D’Angelo
Vice President, CheckFree Customer Operations

I guess we’ll call this the CheckFree botnet?
