    May I ask what I should look for in the log files to detect this (and so I can configure fail2ban correctly)?

      First read this

      Then use the following:

      alert tcp $HOME_NET any -> $EXTERNAL_NET 443 (msg:“[CIS] Emotet C2 Traffic Using Form Data to Send Passwords”; content:“POST”; http_method; content:“Content-Type|3a 20|multipart/form-data|3b 20|boundary=”; http_header; fast_pattern; content:“Content-Disposition|3a 20|form-data|3b 20|name=|22|”; http_client_body; content:!“------WebKitFormBoundary”; http_client_body; content:!“Cookie|3a|”; pcre:“/:?(chrome|firefox|safari|opera|ie|edge) passwords/i”; reference:url,cofense.com/flash-bulletin-emotet-epoch-1-changes-c2-communication/; sid:1; rev:2;)

      And the following:

      alert tcp any any -> any $HTTP_PORTS (msg:“EMOTET:HTTP URI GET contains ‘/wp-content/###/’”; sid:00000000; rev:1; flow:established,to_server; content:“/wp-content/”; http_uri; content:“/”; http_uri; distance:0; within:4; content:“GET”; nocase; http_method; urilen:<17; classtype:http-uri; content:“Connection|3a 20|Keep-Alive|0d 0a|”; http_header; metadata:service http;)

      And also this one:

      alert tcp any any -> any $HTTP_PORTS (msg:“EMOTET:HTTP URI GET contains ‘/wp-admin/###/’”; sid:00000000; rev:1; flow:established,to_server; content:“/wp-admin/”; http_uri; content:“/”; http_uri; distance:0; within:4; content:“GET”; nocase; http_method; urilen:<15; content:“Connection|3a 20|Keep-Alive|0d 0a|”; http_header; classtype:http-uri; metadata:service http;)
