I've looked through some of the contents.. Some look incredibly old, but others target odd things.. lots of cPanel. My only guess is take the low hanging fruit to build "jump box" type systems?
Some odd examples: ElegantEagle/toffeehammer.. focuses on cgiecho for RCE. The thing is, a CVE was just released for this case maybe a month ago?: http://www.cvedetails.com/cve/CVE-2017-5613/
So if this dump was from 2013, why did the CVE recently pop up? Or is that coincidence?
