MyWebSearch was this week's top PUP (Potentially Unwanted Program) worldwide. It is designed to install a search bar on the browser and modify the online search results.

The Zango adware, created to display ads while users browse the Internet, and the FunWeb PUP, have been the next most active malicious codes this week.

As for new malware, this week's PandaLabs report looks at 3 worms: Nussack.A, Nama.A and FlashJumper.M.

Nussack.A is designed to carry out multiple malicious actions. Its keylogger functions enable it to record keystrokes and mouse-clicks. It also carries out annoying actions, such as; opening and closing the CD-DVD drive, displaying the "I Love Kasun" message or making the Internet Explorer window flicker.

It uses USB memory sticks, digital cameras and MP3 players to copy itself onto removable drives and spread.

Nama.A also uses this method to spread. It entices users to run it and then copies itself onto the system using the XLS file names, but with a
VBS extension. It then conceals all the file extensions, so users cannot tell the difference between the original file and the copy of the worm.

This worm prevents programs from running on system start-ups. It also creates registry subkeys that alter the system performance, and which if
not repaired correctly after an infection, could render the system unusable.

Nama.A carries out other malicious actions, such as hiding the Search and Run options in the Start menu, and blocking access to the MS-DOS console.

FlashJumper.M is a worm that copies itself onto the drives connected to the system, including those of the network. It also creates an autorun.inf file on all of them to make sure it is run when users access the drive through Windows explorer.

This worm also creates a key in the Registry Windows to ensure it is run with every system restart.

This week, PandaLabs has also collected information about VoIP security. Further information is available in the PandaLabs blog (http://pandalabs.pandasecurity.com/archive/Security-in-VoIP-Systems.aspx).
