This doesn't look like the correct version, mine looks like this:<br>
<br>
alert http $EXTERNAL_NET any -> $HOME_NET any (msg:"ET TROJAN Possible Andromeda download with fake Zip header (2)"; flow:to_client,established; file_data; content:"PK|03 04|"; within:4; byte_test:1,>,20,1,relative; flowbits:set,et.exploitkitlanding; classtype:trojan-activity; sid:2018576; rev:2;)<br>
<br>
It uses file_data, which is better for accuracy. Interestingly it has rev:2.<br>
<br>
I think you may be pulling your suricata rules from the wrong version:<br>
<br>
e.g.<br>
<a href="https://rules.emergingthreatspro.com/open/suricata/emerging-all.rules" rel="noreferrer" target="_blank">https://rules.emergingthreatspro.com/open/suricata/emerging-all.rules</a><br>
instead of:<br>
<a href="https://rules.emergingthreatspro.com/open/suricata-2.0/emerging-all.rules" rel="noreferrer" target="_blank">https://rules.emergingthreatspro.com/open/suricata-2.0/emerging-all.rules</a><br>
<br>
If you use pulledpork or oinkmaster, could you try updating the URL to include the suricata version like above?<div class="HOEnZb"><div class="h5"><br>
