Some days ago we have reported about vulnerability in the Microsoft Word.
Malware which spreads via email is exploiting the vulnerability as a specially crafted MS-Word .DOC attachment.If the attachment is launched, this triggers a process which results in a backdoor being installed.
Kaspersky lab released detection for the malware, a dropper and backdoor. As ever, users should update their databases as soon as possible. Kaspersky products will detect the dropper as Trojan-Dropper.MSWord.1Table.bd, and the backdoor as Backdoor.Win32.Gusi.a.
