StanCams 0 Posted September 20, 2017 Hi The GM in "GM login" stands for Grain Media (www.grain-media.com) The most common default root password for these units is "GM8182" (without quotes) Hope that helps Share this post Link to post Share on other sites
Inter 0 Posted September 21, 2017 Thank you very much. I will try this password later. Share this post Link to post Share on other sites
kripti 0 Posted September 23, 2017 It's not working, thanks anyway. I tried all the passwords below, none of them works. The DVR without the email/ftp alarms working it's useless... any help from other users would be great. ///dvr pass list// vizxv xc3511 admin admin password xmhdipc root 123456 juantech 888888 default anko support admin1234 54321 1234 1111 Zte521 5up 12345 pass GM8182 guest smcadmin user 666666 1111 system password klv123 ikwb 1111111 user 12345 4321 ubnt dreambox 7ujMko0vizxv 7ujMko0admin 1234 666666 tech supervisor realtek hi3518 fucker meinsm 1234 12345 klv1234 7ujMko0admin pass 54321 888888 service zlxx. jvbzd meinsm 123456 password 1001chin 00000000 //end// Share this post Link to post Share on other sites
kripti 0 Posted September 23, 2017 i think the only solution is to dump the memory and search for the password hash in etc/passwd does anyone has the firmware / dump? i have this DVR Share this post Link to post Share on other sites
Inter 0 Posted September 24, 2017 You can probably use JTAG interface to dump the contents of flash memory chip Share this post Link to post Share on other sites
