It's in regards to some Russian hacking groups and networks, and a 'trojan' that was created. The short of it is that this trojan is installed on the victim system. The attackers sell these infected machines like bots. However, they sell them for 30-day (for example) increments. For those 30 days, the buyer can login to a web portal and view all sorts of information (just like a standard trojan) about the victim machine. The buyer is hoping to collect identity information from their 'project,' or group, of infected machines. Great read, real interesting.
