This is the exact rule I want it to fire on.

Code: Select all

Here is the new rule:

Code: Select all

# BLOCKING ModSec Rules attacks

	if (($lgfile eq $config{CUSTOM1_LOG}) and ($line =~ /^\[\S+\s+\S+\s+\S+\s+\S+\.\d+\s+\S+\] \[\S+:error\] \[pid \d+.*\] \[client \S+\] \[client (\S+)\] ModSecurity.*\[id "(210280|210350|210380|210481|210492|210710|210730|210831|210921)"\]/i)) {
		return ("mod_security attack id $2",$1,"SecmasRules_ModSec","1","1");
	}
