I just had a customer complain of the same issue. All of the cameras are blank and each one re-named "Hacked". This hasn't happened to any of the SCK units I've installed thus far, around 5. Is this a commonality as of late?

For additional information:

There has been a widespread occurrence of DVR and NVR recorders being hacked remotely. A couple of weeks ago a backdoor vulnerability affecting up to 250,000 Hikvision devices was publicized and now we have been notified by another factory (the second largest security manufacturer in the world) that their recorders have a vulnerability that is being exploited worldwide on their recorders . It appears the hackers have found a way to use the local only 888888 user remotely in order to access the system. The attack makes changes to the video settings in order to make the screens black and rename the cameras as “Hacked”. It does not appear that they have modified or altered any of the stored recordings, nor have they locked the user out of the system.
As a supplier of security cameras from the 3 largest manufacturers we do our very best to
provide industry leading technical support and service to our customers.

The steps to remedy the issue are as follows:

1. Log into the recorder locally using the 888888 username and password.
2. Go to the default menu and click factory default.
3. Log back into the unit and in the system info section record the serial number and
   firmware version information.
4. Provide the serial number, Model Number (found on back of unit) and firmware version
   to us.
5. We will provide updated firmware if available.
6. Load firmware into the device locally with a USB stick or over the network from your
   PC.(Our Tech Support can assist with this step).
7. After the upgrade is done change all your account passwords from default to a secure
   password using a combination of upper and lower case letters and numbers, eight
   characters or more and if you want network access, change the default port numbers
   from the default 37777 and 37778. Do not use port 80 and we recommend anything
   above 1024.
