Duqu, sounds funny, but is a serious and major threat around the web since last month. Researchers investigated about Duqu and came out some shocking results, Duqu’s source code is much alike Stuxnet Virus, which created huge havoc with Iran’s nuclear program. This either means that this new virus comes from the Stuxnet developer team or Stuxnet source code was stolen. Whatever might be the cause, Duqu still remains in dark and a lot of secrets are yet to be explored regarding this virus.
How it works?
Still remains the mystery, but broadly it links with a piece of software downloaded as corrupted Microsoft Word Document. In simple words, Duqu infects Windows PCs using a malformed Word Document. When user opens the word document, this action triggers the environment for Duqu’s installation on PC.
What it can do?
Symantec identified Duqu as the ultra-sophisticated worm and Microsoft classified the vulnerability as an elevation of privilege bug. Microsoft, in its posting Thursday night, said that, if successful, the Duqu attacker could “install programs; view, change, or delete data; or create new accounts with full user rights”. This means the hacker allegedly gets full control of your system and needless to say the possibilities then after, this virus is sure to be prevented.
