Detailed Analysis

According to this email, which claims to be from US natural gas provider Atmos Energy, the recipient can view the latest Atmos energy bill by clicking a link.  The email also invites people to find out more about natural gas by clicking other links. The message includes a customer account number, current charges, and the date the supposed bill was issued.

However, the email is not from Atmos. Clicking any of the links in the email will take users to a compromised website that harbours the Kuluoz malware. Once installed, Kuluoz can join the computer up to the Asprox botnet and download and install more malware components.

Atmos has published a notice on its website warning users about the scam emails. The warning notes that the emails are coming from an address that is not affiliated with Atmos Energy and uses fake account numbers.

If you receive this email, do not click any links or open any attachments that it contains.

Malware distributors and phishing scammers often use fake bill notification emails as a means of gaining victims. Be wary of any unsolicited email that claims that you can view a bill by clicking a link or opening an attached file.  

Of course, some service providers do send bill notifications via email, usually because a customer has explicitly chosen to receive email rather than paper bills. Thus, it is important that you carefully check that a bill notification email is really from your provider before clicking links or opening attached files.
