Dubbed “AirHopper” by the researchers at Cyber Security Labs at Ben Gurion University, the proof-of-concept technique allows hackers and spies to surreptitiously siphon passwords and other data from an infected computer using radio signals generated and transmitted by the computer and received by a mobile phone. The research was conducted by Mordechai Guri, Gabi Kedma, Assaf Kachlon, and overseen by their advisor Yuval Elovici.

The attack borrows in part from previous research showing how radio signals (.pdf) can be generated by a computer’s video card (.pdf). The researchers in Israel have developed malware that exploits this vulnerability by generating radio signals that can transmit modulated data that is then received and decoded by the FM radio receiver built into mobile phones. FM receivers come installed in many mobile phones as an emergency backup, in part, for receiving radio transmissions when the internet and cell networks are down. Using this function, however, attackers can turn a ubiquitous and seemingly innocuous device into an ingenious spy tool. Though a company or agency may think it has protected its air-gapped network by detaching it from the outside world, the mobile phones on employee desktops and in their pockets still provide attackers with a vector to reach classified and other sensitive data.

An advanced piece of malware, known as Regin, has been used in systematic spying campaigns against a range of international targets since at least 2008. A back door-type Trojan, Regin is a complex piece of malware whose structure displays a degree of technical competence rarely seen. Customizable with an extensive range of capabilities depending on the target, it provides its controllers with a powerful framework for mass surveillance and has been used in spying operations against government organizations, infrastructure operators, businesses, researchers, and private individuals.

It is likely that its development took months, if not years, to complete and its authors have gone to great lengths to cover its tracks. Its capabilities and the level of resources behind Regin indicate that it is one of the main cyberespionage tools used by a nation state.

As outlined in a new technical whitepaper from Symantec, Backdoor.Regin is a multi-staged threat and each stage is hidden and encrypted, with the exception of the first stage.  Executing the first stage starts a domino chain of decryption and loading of each subsequent stage for a total of five stages.  Each individual stage provides little information on the complete package. Only by acquiring all five stages is it possible to analyze and understand the threat.
