<body class='hmmessage'><div dir='ltr'>Thank you for this. One of our Linux guys helped me out getting it working. He also made some changes so I figured I'd update here. I noticed i needed to install mawk and gawk to get it to work.<BR>wget -qO - <a href="http://www.twitter.com/efensive">http://www.twitter.com/efensive</a> |\<br> awk '/VoIP/ {print gensub(".*>", "", "G", $3)}'<BR> <BR>Brian<br> <BR><div>> Date: Wed, 15 May 2013 09:41:31 -0500<br>> From: joquendo@e-fensive.net<br>> To: voiceops@voiceops.org<br>> Subject: [VoiceOps] Parsing VoIP attacker Twitter feed<br>> <br>> Sorry had to start a new thread (Thunderbird filters via<br>> MS + FreeBSD aren't playing nicely).

I would never bother to<br>> use REJECT since it wastes time/resources telling an<br>> attacker: "I'm REJECTING this packet" YMMV.<br>> <br>> The reasoning for grep'ing ('/VoIP/' in awk) is that every<br>> once in a while I may babble on, or post say APT (the big<br>> bad Chinese/German/Russian boogeyman) threats in my stream<br>> as well as malware related hosts/domains as well.
