fgrep XDVR (cctv/dvr)

fgrep XDVR (cctv/dvr)

Yeah I saw it too. With some Google search, I believe it is waiting for the specific responses of the content in dep2.sh. I am trying to the real content of dep2.sh, no luck as for now

Also, I saw there are always same credentials prior these fgrep attempts.

I will try to dig further

I did some research on this and found: https://github.com/k1p0d/h264_dvr_rce/blob/master/h264-dvr-rce.py and the article had some references to the dep2.sh file

I tried using the dep2.sh file from: http://qsee.custhelp.com/app/answers/detail/a_id/1275/~/qt446%3A-firmware-version-3.2.0-(latest)

And get no responses. That fgrep on the dep2.sh from the linked firmware will return cd /mnt/mtd && ./XDVRStart.hisi ./td3520 &

Ah, nice catch @wintermanc3r . Did you add that string to Glutton to see if we see further steps in that attack scenario?

I've actually been using my own honeypot (this is literally the only link on Google I could find that applies to this traffic!), but I've tried
cd /mnt/mtd && ./XDVRStart.hisi ./td3520 & and
cd /mnt/mtd && ./XDVRStart.hisi ./td3520a &

without any success. This is definitely the right track so I'm going to poke around some more and see if I can find any other versions of the firmware, and will let you know if I find the desired response. Between this and the bot I've ran into running crontab, passwd, reboot (that actually tried repeatedly to shut my honeypot down with forkbombs and /dev/urandom redirection) things get more curious every day...

Nice @wintermanc3r . I am adding to mine and testing it now. Will see what we can get later. Cheers!

[glaslos]

@gento any success?

@glaslos I tried the same way as @wintermanc3r

cd /mnt/mtd && ./XDVRStart.hisi ./td3520 &

No luck for me as the moment
