I also build and ship custom machines at a really fair price.Even the cleverest malware is stranded unless it can communicate with the people who sent it. This can be hard to achieve without a network’s defenders noticing the malware’s chatter, so stealthy communication is at a premium for malware that wants to go unnoticed. The most extreme example of this challenge occurs when malware has no direct connection to the outside world at all, such as is the case in isolated networks that are “air-gapped” from the outside world. In this situation, the malware typically has two ways to communicate: infect storage media used to ferry data and software to and from the protected network (the approach used by the infamous Stuxnet malware), or get an insider to access the gapped systems. #Sophos power and disk led blink software# Researchers at Israel’s Ben-Gurion University prefer a third way: they’ve come up with a new proof-of-concept gap-beating attack, dubbed “ aIR Jumper”, based on controlling the infrared (IR) LEDs inside surveillance cameras. The team wanted to see whether these devices could be used to jump the gap and exfiltrate data (sneak it out of a network), infiltrate data (sneak it in as part of command and control) or, ideally, a combination of the two. To work, the malware (already inside the air-gapped network using one of the techniques mentioned above) must look for and compromise network-attached surveillance cameras, which are typically fitted with infra-red LEDs to enable night vision.įor cameras facing on to a public car park or street, the researchers discovered that data could be exfiltrated as encoded infra-red flashes at throughputs of 20 bits/sec, per camera, to an attacker with a video camera standing tens of metres away.Ĭommand and control data could then be infiltrated back to the malware by reversing this process at a throughput of 100 bit/sec, per camera, using infra-red LEDs from kilometres a way. Sensitive data such as PIN codes, passwords, and encryption keys that are then modulated, encoded, and transmitted over the IR signals.
