Hidden backdoor discovered in Chinese IoT devices

“Researchers at Trustwave have uncovered a backdoor in IoT devices from a Chinese manufacturer that could leave them open to exploitation,” Ian Barker reports for BetaNews.

“The backdoor is present in almost all devices produced by VoIP specialist DBLTek, and appears to have been purposely built in for use by the vendor,” Barker reports. “The issue permits a remote attacker to gain a shell with root privileges on the affected device.

Barker reports, “Full details of the exploit and the devices affected can be found on the Trustwave blog.”

  1. The NSA, and by extension all of the other spy agencies, know about all back doors in all devices. It deplors that vigilantees like Trustwave blew the whistle. Should DBLTek eliminate the back door, the NSA will lose some of its unaccountable and secret spy capability which it considers its exclusive domain.

  2. This case appears to be one of sloppy software engineering and testing practises rather than of deliberate spying. Regardless, it formed the basis of an exploit that affects ten thousand security cameras, not a good thing. The company doesn’t want to recall them; too expensive to contemplate. They need to hire a consultant to help them do a proper firmware upgrade.
