Hi
I am building a site http://jobfairinsider.com/ which internally uses
couchdb 1.6.1 for data hosting and management. I have backups etc. - So
the purpose of this post is more to share details about the intrusion
and to get everyone's feedback on how to investigate it and avoid it in
the future.
My setup has an admin user in couchdb whose password I dont think was
compromised (as confirmed by log grep on _session). I had port 5984
open for some time while developing and improving the site and its content.
The intrusion deleted all the databases and created a pleaseread
database with a ransom note. The contents are available here:
http://jobfairinsider.com:5984/_utils/document.html?pleaseread/5dc534179e5689037c222ed3fb36bf1b
The logs from couchdb are given at bottom. I do not see _session to
login but the databases could all be deleted. I was expecting this
behavior:
[Thu, 19 Jan 2017 20:35:42 GMT] [info] [<0.4041.0>] 127.0.0.1 - - DELETE
/testdb 401
But what we got is given below.
Thoughts?
Thanks
Vivek
