Hackers Can Steal Data From Air-Gapped Industrial Networks via PLCs
Security Week | December 06, 2017
Researchers have discovered a method that hackers could use to stealthily exfiltrate data from air-gapped industrial networks by manipulating the radio frequency (RF) signal emitted by programmable logic controllers (PLCs). Attackers may be able to plant a piece of malware on an isolated network, including via compromised update mechanisms or infected USB drives, but using that malware to send valuable data outside the organization poses its own challenges.
