Free whitepaper – What you need to know about cloud backup
It’s been known for some time that “smart TVs” are dumb about security, but a German researcher has demonstrated that the stupidity goes so far as to enable remote snooping or even a takeover of the in-set computer.
Nruns researcher Martin Herfurt has taken work begun at the Darmstadt University of Technology to demonstrate a range of remote attacks on Samsung Hybrid Broadcast Broadband TVs – HbbTVs – that include WiFi eavesdropping, fake analytics, content redirection, fake news tickers, Bitcoin mining and more.
Herfurt’s post describing the attacks, here, credits TU Darmstadt for demonstrating that MAC addresses and packet lengths sniffed from the TV’s WiFi stream allow an eavesdropper to snoop someone’s viewing habits.
This, Herfurt writes, makes it trivial for an attacker to inject their own URLs into the stream, or use DNS attacks to redirect the TVs to their own content. He also noted that none of the broadcasters using HbbTV capabilities are doing so over SSL, allowing content spoofing.
