Scientist-developed malware covertly jumps air gaps using inaudible sound

Computer scientists have developed malware that uses inaudible audio signals to communicate, a capability that allows the malware to covertly transmit keystrokes and other sensitive data even when infected machines have no network connection.
The proof-of-concept software—or malicious trojans that adopt the same high-frequency communication methods—could prove especially adept in penetrating highly sensitive environments that routinely place an “air gap” between computers and the outside world. Using nothing … Read More → "Scientist-developed malware covertly jumps air gaps using inaudible sound"
