Hikvision Responds To Cracked Security Codes

By: Brian Karas, Published on Aug 15, 2017

Hikvision has responded to IPVM's report on Hikvision's security code being cracked, both with a 2 page update to dealers and communication directly with IPVM.

In this note, we examine Hikvision's response, evaluating the positive and negative elements of it.

Good

On the positive side, Hikvision:

  • Revamped the password reset procedure to a method that is more challenging to crack
  • Has been releasing new recorder firmware that makes an improved method available to users

Bad

On the negative side, problems remain:

  • Hikvision knew about the cracked codes for a long time but never notified dealers until after IPVM published
  • The new method still cannot be disabled
  • The new method still risks being cracked
