Security researcher Bashis has disclosed a backdoor in TVT video surveillance products, with TVT issuing its own 'Notification of Critical Vulnerabilities'. Bashis has found numerous vulnerabilities in video surveillance products, most notably the 2017 Dahua backdoor, which later resulted in the industry's most widespread hacking attack.

In this note, we examine the TVT backdoor and TVT's response.
