Introduction Alright guys, this is a biggie. Shellshock allows remote code execution and file creation for any server relying on bash v3.4 through v1.1. If you are using Redhat or CentOS and the default shell, your server is vulnerable. The patching history was sketchy, as well. If you patched immediately when the bug came out using  CVE-2014-6271 , you are still likely vulnerable (as of right now, 9/26/2013 12:50PM EST). Run the following to apply the patch: #yum update bash You need CVE-2014-7169  if you are using Red Hat Enterprise Linux 5, 6, and 7. Note that 2014-7169 DOES NOT address the following operating systems, which as of right now are still not fully patched: Shift_JIS, Red Hat Enterprise Linux 4 Extended Life Cycle Support, Red Hat Enterprise Linux 5.6 Long Life, Red Hat Enterprise Linux 5.9 Extended Update Support, Red Hat Enterprise Linux 6.2 Advanced Update Support, and Red Hat Enterprise Linux 6.4 Extended Update Support If you applied CVE-2014-6271 and nee

I've spotted a trojan/shell exploit that targets ASP.NET named ASPY.a making the rounds again recently. By no means a 0-day or brand new bit of malware, ASPY.a has been around for about 2 years . It takes advantage of vulnerable ASP scripts, uploads itself to a web server and in unpatched systems that lack sensible permissions policies and the latest updates, it can grant remote attackers administrator access. Microsoft Security Essentials will catch it, however I've seen at least one version of Symantec that does not completely remove compromised files - with Symantec server-level compromise was prevented, but the website itself remained controllable. So why am I writing a post about a 2 year old piece of malware? The story here is that the circulation appears to be driven by a developer based in Russia that sells "server control panel" (панель управления сервером, управление) software for novices tasked with IIS-based website management. The name of the company is
