Feature #4876
openAdditional FTP Buffers
Description
We continue to see popular commodity and APT based malware using FTP as an exfil protocol (https://attack.mitre.org/techniques/T1048/003/). There are currently very few FTP buffers and even signatures as simple as looking for specific usernames require unbuffered content matches, often times increasing the complexity of the rule and making it more prone to FN/FP.
I'd be open to provide feedback on buffers required, though I think a general purpose client -> server buffers of ftp.command, ftp.command_data and server -> client of ftp.completion_code and ftp.reply which match the current logging would be a good improvement.
As a side note - The current ftp-data example contained here https://suricata.readthedocs.io/en/latest/rules/ftp-keywords.html is a bit confusing as it makes use of the `filename:"password"` however, as I understand it, that option can be used in non filestore signatures.
