AirHopper — Hacking Into an Isolated Computer Using FM Radio Signals

In order to secure sensitive information such as Finance, many companies and government agencies generally use totally secure computer systems by making sure it aren't connected to any network at all. But the most secure systems aren't safe anymore.
Security researchers at the Cyber Security Labs at Ben Gurion University in Israel have found a way to snoop on a personal computer even with no network connection.

STEALING DATA USING RADIO SIGNALS
Researchers have developed a proof-of-concept malware that can infiltrate a closed network to lift data from a machine that has been kept completely isolated from the internet or any Wi-Fi connection by using little more than a mobile phone’s FM radio signals.
Researcher Mordechai Guri, along with Professor Yuval Elovici of Ben Gurion University, presented the research on Thursday in the 9th IEEE International Conference on Malicious and Unwanted Software (MALCON 2014) held at Denver.
This new technology is known as ‘AirHopper’ — basically a keylogger app to track what is being typed on the computer or the mobile phone.
AirHopper is a special type of keylogger because it uses radio frequencies to transmit data from a computer, all by exploiting the computer's monitor display, in order to evade air-gap security measures.

"This is the first time that a mobile phone is considered in an attack model as the intended receiver of maliciously crafted radio signals emitted from the screen of the isolated computer," according to a release by Ben Gurion University.

Kui Wordi kirjutatakse monitorisuurusi tähti, siis 7m kauguselt piisab inim- kaamerasilmast juba "pealtkuulamiseks". Lahenduseks oleks monitori poolt välja saadetav signaal müraks muuta näidates ekraanil suvalist liikuvat asja või lihtsalt kasutada väiksemat fonti, et vähendada müra arusaamatule tasemele.
Lisaks ma arvan, et monitori varjestuse täiustamisega saaks vabalt selle "augu" kinni panna. Kui see kuulamine üldse praegugi võimalik on normaalsete "mitte Hiina" monitoridega. See on ju ka ära määratud kui palju tohib elektroonika õhku müra pritsida.
