Honeypot – Scanning and Targeting Devices & Services, (Sat, Mar 21st)

I was curious this week to see if my honeypot traffic would increase since a large portion of the world is working from home. Reviewing my honeypot logs, I decided to check what type of filename was mostly targeted (GET/POST/HEAD) by scanners  this past week on any web supported ports (i.e. 80, 81, 8000, etc). This first graph shows overall activity for the past 7 days.

The following graph shows 86 different files picked picked up in the past week. Obviously some are familiar and non malicious (i.e. robot.txt, favicon.ico, etc) but a lot of the others are suspicious (i.e. various nmap nse scripts).

I included a few interesting GET/POST that got captured over this past week but infortunatly, the files listed in here are no longer available for analysis:

This random hostname (jhasdjahsdjasfkdaskdfasBOT.niggacumyafacenet.xyz) is no longer active. I was able to find information about it on URLhaus [1] matching the same URL.

The file (Mozi) is an ELF (Linux) file use by the Mirai botnet [2].

If you have a Netgear router, make sure it is patched.
