The T9000 backdoor was spotted by researchers at Palo Alto Networks. It is a hybrid variant of another malware dubbed T5000 that was detected in the wild two years ago. Malware is able to steal files, take screengrabs, and record Skype conversations. 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 was used by threat actors to targets organizations worldwide, the researchers observed it used in multiple targeted attacks against US organizations.”]
