The Windows assault used by a newly discovered worm is being lifted up by another virus critic and will shortly develop into a lot more extensive, as per the security vendor Eset.

Eset stated that two novel families of hateful software have arise, together of which exploit vulnerability in way Windows processes .link files, utilize to give shortcuts to other files on system.

The vulnerability was initially browbeaten by Stuxnet worm, located on PC systems in Iran previous month. Extremely sophisticated, Stuxnet intentions systems running Siemens industry control system management software the worm takes SCADA (supervisory control and data acquisition) project files from Siemens' PC systems.

Siemens concern a Security Update for its users, but Microsoft has still to patch Windows bug that allows worm to extend. The recently discovered malware is "far less sophisticated" than Stuxnet and "advises bottom feeders seizing on techniques developed by others," said Eset researcher Pierre-Marc Bureau.

One of the new examples installs a keystroke logger tool hackers utilize to take passwords and other data, on victim's PC. "The server used to deliver parts used in this attack is currently located in US, but the IP is assigned to a client in China," Bureau said. The other variation might be used to install one of some dissimilar pieces of malicious software.
