Kibkalo was terminated by Microsoft after an internal investigation, prompted by the discovery of emails from him to the blogger, whose Hotmail account contents had been read by officials in Microsoft's Trustworthy Computing Investigations (TWCI), a department tasked to protect the company from outside hackers and internal leakers. Kibkalo allegedly used his own Hotmail account to contact the blogger and his SkyDrive account to share code, including the Activation Server SDK.
