Dell warns of malware on motherboards

Dell PowerEdge
Updated Dell has published a warning on its support forum that some of its server motherboards are infected with Windows malware.

The admission, posted in response to a customer who wished to confirm that a telephone call he had received from a Dell representative was genuine, confirmed that “a small number of PowerEdge server motherboards” may contain spyware in its embedded server management firmware.

Dell says that it has created a list of affected customers, and that they are formally notifying them of the security problem via letter.

Unfortunately, as The Register points out, no specifics are offered as to which malware has infected the motherboards, or what it does.

Even though it is believed that the malware only affects Windows-based operating systems, this is still embarrassing for Dell – and questions will be asked as to whether stringent enough quality control measures were in place to prevent unauthorised code from shipping with their hardware.

Update Since I posted the above article, Dell has now published further information on the incident. Apparently the malware concerned was a common version of the “Win32.Spybot” family that any decent anti-virus product should be able to detect, and the infection was found on the motherboard’s flash storage not its firmware.
