The number of exploit kits available has experienced exponential growth in the last few years. Since Blackhole’s author was arrested in 2013, the number of Exploit Kits has increased – including Neutrino, Magnitude, Nuclear, Rig and Angler. Below, Jaime Blasco, Director of AlienVault Labs, discusses Archie, an Exploit Kit that was first discovered by William Metcalf at EmergingThreats.
Archie is a really basic Exploit Kit that uses different exploit modules copied from the Metasploit Framework. When the victim lands on the main page, Archie uses the PluginDetect Javascript library to extract information about Flash, Silverlight and Acrobat Reader versions, and the information is sent to the server.

It also uses the following trick to check whether or not the system is running a 64-bit version of Internet Explorer.
Depending on the Silverlight, Internet Explorer and Flash versions, it will try to load a different exploit module.
Archie contains shellcode in different formats that is sent to the different exploit modules generated by Metasploit when it loads them.
The shellcode downloads a DLL from the webserver, writes it in \Users\[Current_user]\Temp\e.dll and then loads it.
The IP address where the Archie Exploit Kit is hosted, and the piece of malware delivered, is also being used for click fraud operations. It is related to this research published by Kimberly on the click fraud bot.
