Be vigilant against Dasher warns Internet Security Systems

“As the Christmas holiday season begins, a new worm has hit the Internet called Dasher. It is exploiting a known and patched Microsoft issue – MS05-051. Network and IT managers need to be vigilant and ensure that all systems are up-to-date,” comments James Rendell, technical product manager at Internet Security Systems.

“This new worm aims install software that tries to infect other vulnerable systems, and that also can be used to log keystrokes and turn the computer into a remotely controlled “bot’ system.

“By opening suspicious emails and attachments, users install the dangerous spyware on their computers where it can cause considerable damage. We advise companies to make sure that their IT systems are updated immediately and the correct levels of protection are put in place for all users.

“It is far safer to be proactive in situations such as these as it could become a costly expense for any company if a reactive approach is taken to network security.”
