The published analysis reveals that the botnet includes both a sophisticated infection method and a post-infection behaviour pattern that are based on a highly customizable engine. The researchers note that this has produced a botnet that is currently rated as one of the most sophisticated ones. At the same time there is no information available about the identity of the hacker or criminal collective behind it.

The published reports do not give reveal the exact infection mechanism as the discovery was made on systems that were already compromised. Given the situation there are several possible entry points that the malicious code might have used.

One of the options is the use of infected email messages, specifically those that rely on social engineering techniques. The criminals can attempt to create counterfeit messages and notifications that use the names, text and graphics of famous companies. They can contain contain attached copies or hyperlinks placed in the body contents.
