VERY IMPORTANT

Most custom backdoors used by advanced attackers have limited functionality. They evade detection by keeping their code simple and flying under the radar. But during a recent investigation we found a backdoor that takes a very different approach. We refer to this backdoor as T9000, which is a newer variant of the T5000 malware family, also known as Plat1. In addition to the basic functionality all backdoors provide, T9000 allows the attacker to capture encrypted data, take screenshots of specific applications and specifically target Skype users. The malware goes to great lengths to identify a total of 24 potential security products that may be running on a system and customizes its installation mechanism to specifically evade those that are installed. It uses a multi-stage installation process with specific checks at each point to identify if it is undergoing analysis by a security researcher. The primary functionality of this tool is to gather information about the victim.
