Banload sigs

[Y M <snort () outlook com>]

The reference is in Spanish, so mind not my bad translation of the alerts' msgs. Quick and dirty signature:
alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"MALWARE-CNC Win.Trojan.Banload outbound connection attempt"; 
flow:to_server,established; content:"/v22/mutabixa/"; fast_pattern:only; http_uri; metadata:impact_flag red, policy 
balanced-ips drop, policy security-ips drop, ruleset community, service http; 
reference:url,www.nyxbone.com/malware/banload.html; classtype:trojan-activity; sid:100049; rev:1;)
alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"MALWARE-CNC Win.Trojan.Banload information upload attempt"; 
flow:to_server,established; content:"/v22/mutabixa/1nf3ct/"; http_uri; content:"chave="; distance:0; http_uri; 
content:"&url="; distance:0; http_uri; metadata:impact_flag red, policy balanced-ips drop, policy security-ips drop, 
ruleset community, service http; reference:url,www.nyxbone.com/malware/banload.html; classtype:trojan-activity; 
sid:100050; rev:1;)
alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"MALWARE-CNC Win.Trojan.Banload download attempt";
