    Hacked DVR--Dahua

    I had 8 DVR's Hacked this weekend. They used telnet to hack the dvr's. Every one was accessed using the LOCAL ADMIN(88888888) acct. Mine even had the passwords changed. They proceeded to change the color on all the cameras to make it appear black or off. They also Labeled all the Camera's Hacked. The Ip Address was changed rendering the device offline and now unable to fix remotely. This was all done in under a second. All the devices logs showed IPS from Amsterdam for the login. Probably a vpn of some sort or annonomizer. It would be nice if the DVR's could just update automatically to the new firmware.. What a pain in the ass. Anyways. You don't need to factory default the device as they just changed settings. So simply change them back. Update all passwords aswell. But do Upgrade to the latest firmware.. If your network knowledgeable possibly changing ports on your router and forwarding to the dvr parts may also make it more difficult to hack in the future. Ive done this but for multiple dvr's at the same location and it works well... Hope this helps anyone that may have been hacked..
