A team of software and information systems engineers at Ben-Gurion University of the Negev, in Israel, has demonstrated an ability to extract useful data from an air-gapp<\/a>ed computer. The group has posted a paper<\/a> to the arXiv<\/i> preprint server describing their experiments and results.<\/p>\n

Over the past several years, hackers have made headlines by sneaking their way onto computer systems used for public services, such as monitoring water treatment equipment. Others have conducted denial-of-service attacks on larger systems, or more brazenly, ransomware attacks on hospitals or other critical service systems.<\/p>\n

One thing they all have in common is their connection to the Internet, leading some to wonder why such user sites connect to the Internet if it makes them so vulnerable. In this new effort, the research team in Israel has found that even computers not connected to the Internet can be vulnerable to attack.<\/p>\n

Computers that are not connected to another network, or the Internet, are said to be air-gapped\u2014there is nothing but empty air between them and any other computer. Such systems would seem to be impervious to attack, especially since floppy drives are no longer used. But that is not always the case as the researchers have demonstrated.<\/p>\n

To show that it is possible to hack an air-gapped computer, the researchers developed a type of malware that manipulates the RAM on a target computer into generating very faint radio signals. The software was designed in such a way that the radio waves that were generated reflected data held on the RAM devices and were encoded in such a way as to be readable from a nearby device.<\/p>\n
