Reports surfaced last week of the Shylock financial malware spreading on Skype. Researchers found two worms, Bublik and Phorpiex, spreading mostly in Japan. Bublik is a backdoor with rootkit functionality; Bublik can enable remote access for an attacker, download and upload files to a C&C server, download additional plug-ins and monitor browser activity. A malicious plug-in enables the malware to send messages and transfer files, wipe out messaging history, bypass Skype warnings, and send requests to a third-party website.
