Malicious Faxes Leave Firms 'Open' To Cyber-Attack

Booby-trapped image data sent by fax can let malicious hackers sneak into corporate networks, security researchers have found. From a report: Since many companies use fax machines that are also printers and photocopiers, they often have a connection to the internal network. The malicious images exploit protocols established in the 1980s that define the format of fax messages. The research was presented at the Def Con hacker conference in Las Vegas. The two researchers said millions of companies could be at risk because they currently did little to secure fax lines. "Fax has no security measures built in -- absolutely nothing," security researcher Yaniv Balmas, from Check Point software, told the BBC. Mr Balmas uncovered the security holes in the fax protocols with the help of colleague Eyal Itkin and said they were "surprised" by the extent to which fax was still used.
