A new information-stealing Trojan, believed to be of Chinese origin, has been identified by Avira researchers. This malware targets usernames and passwords for a variety of popular websites, including YouTube, Google, and PayPal, as well as Chinese sites like Youku, Tudou, Sogou, and Soho. The stolen credentials are sent to a server in China, reinforcing the researchers' belief about its origin.
Unlike typical Trojans that modify registry keys or exploit the autorun feature to ensure execution, this Trojan exhibits unique behavior. It specifically targets shortcuts on the desktop or in special folders. The Trojan duplicates itself and places copies in folders containing the linked files, often executables. It renames the original files to click_[original-file-name].exe and assigns the original file names to its copies.
As a result, each time a user clicks on a shortcut, the Trojan runs. To avoid detection for as long as possible, these copies are programmed to execute the renamed files after running themselves.
