Context
The threat was a multi-stage malware displaying a decoy that appeared to the victim as a Chinese language article on the long-running dispute over the Diaoyu Islands; an array of erotic pictures; or images of Tibetan organisations. It consisted of two stages: Revir was the dropper/downloader and Imuler was the backdoor capable of the following operations: - capture screenshots - exfiltrate files to a remote computer - send various information about the infected computer - extract ZIP archive - download files from a remote computer and/or the Internet - run executable files
