Cyber-criminals eye fiber tapping as hacking alternative

Cyber-criminals have reportedly begun to consider fiber tapping as a viable alternative to hacking heavily shielded systems.
“You can buy a non-intrusive tapping device on eBay for about $1,000,” Christian Illmer, senior director at ADVA Optical Networking, told ComputingUK.
“[So] the data stream isn’t interrupted, you just take some of the light.”
According to Illmer, fiber tapping is notoriously difficult to detect.
“If a user were monitoring the link, they would see only a very slightly higher level of loss, perhaps from 20dB to 21dB. This is certainly not sufficient to trigger many alarms,” he explained.
“[Still], if you’re tapping into a link, you have to know what you’re looking for – because there could be as many as 80 data streams.”
