RST virus:
==========
Quick and dirty way to find infected files: find . -type f -exec strings --all {} \; |grep snortdos
Files: "Dumb" scan of all files
Switches: -ARCHIVE -PACKED -SERVER
/tmp/scaner/go Infection: Unix/RST.B
/tmp/scaner/pscan2 Infection: Unix/RST.B
/tmp/scaner/ss Infection: Unix/RST.B
/tmp/scaner/ssh-scan Infection: Unix/RST.B
/tmp/scaner/sshf Infection: Unix/RST.B
Results of virus scanning:
Infected: 5
Seems that infected files are updating them at each run and modify the timestamp

21:17 corresponds to the crash of the server so probably infected executables are left open even after being killed

TODO:
=====
ftp repository of test??
/var/cache/tct
Conclusions
- Initial breach
- automatic tool scanning ftp accounts could enter with the 'test' account
- manual attempt to log in with the 'test' account
- download over of sniffers and brute-force tools for ssh
- transfers over ftp
- change test password
- 82.79.137.NN = NN.metronetwork.rdsbz.ro
- 193.230.222.209 = 209-nat.s-man.net
- Counter-measures
- don't use dummy passwords ;-)
- don't grant ftp/ssh rights per default
sshd: make use of the "AllowUsers" keyword and explicitely add users when needed - don't grant internet access per default
iptables: cf --uid-owner and other --XXX-owner options
on OUTPUT table to avoid download of malicious code
on INPUT table to avoid bindshells
- Timeline
- Before and during the live forensic analysis we should have written down our own actions and the observable elements rather that having to deduce them from the logs.
