A fridge has been discovered sending out spam after a web attack managed to compromise smart gadgets.
The fridge was one of more than 100,000 devices used to take part in the spam campaign.
Uncovered by security firm Proofpoint the attack compromised computers, home routers, media PCs and smart TV sets.
The attack is believed to be one of the first to exploit the lax security on devices that are part of the "internet of things".
Poor protection
The spam attack took place between 23 December 2013 and 6 January this year, said Proofpoint in a statement. In total, it said, about 750,000 messages were sent as part of the junk mail campaign. The emails were routed through the compromised gadgets.
About 25% of the messages seen by Proofpoint researchers did not pass through laptops, desktops or smartphones, it said.
Instead, the malware managed to get itself installed on other smart devices such as kitchen appliances, the home media systems on which people store copied DVDs and web-connected televisions.
Many of these gadgets have computer processors onboard and act as a self-contained web server to handle communication and other sophisticated functions.
Investigation by Proofpoint into the internet addresses involved in the attack revealed the presence of the smart gadgets, said David Knight, general manager of Proofpoint's information security division.
