Malicious DIY Java applet distribution platforms going mainstream – part two

by


In a cybercrime ecosystem, dominated by client-side exploits serving Web malware exploitation kits, cybercriminals continue relying on good old fashioned social engineering tricks in an attempt to trick gullible end users into knowingly/unknowingly installing malware. In a series of blog posts, we’ve been highlighting the existence of DIY (do-it-yourself), social engineering driven, Java drive-by type of Web based platforms, further enhancing the current efficient state of social engineering driven campaigns.

Let’s take a peek inside yet another Web based DIY Java applet distribution platform, discuss its features, and directly connect to the Rodecap botnet, whose connections with related malicious campaigns have been established in several previously published posts.

The cross-platform (Windows, Mac, Linux) Web based DIY Java applet distribution platform currently exploits a well known vulnerability in Java v.7u21, for the purpose of dropping malicious code on the exploited hosts, and supports detailed statistics for the number of successful installations.
