Microsoft software bug linked to “Duqu” virus
New unknown bug causes exploit to Windows operating system infecting computers with the Duqu virus and has some experts worried that it could be the next big cyber threat. Microsoft says they are working to resolve the issue and will release a security update for its customers.
Government and private investigators around the world are racing to unlock the secret of Duqu, with early analysis suggesting that it was developed by sophisticated hackers to help lay the groundwork for attacks on critical infrastructure such as power plants, oil refineries and pipelines.
Details on how Duqu got onto infected machines emerged for the first time on Tuesday as Microsoft disclosed its link to the infection.
Separately, Symantec researchers said they believe hackers sent the virus to targeted victims via emails with tainted Microsoft Word documents attached.
If a recipient opened the Word document and infected the PC, the attacker could take control of the machine and reach into an organization’s network to propagate itself and hunt for data, Symantec researcher Kevin Haley told Reuters.
