Security experts at MicroWorld Technologies inform that a worm named “Worm.Win32.Scano.e’ spreads via emails written in Russian carrying an attachment in “HTA’ format.
The malicious component of this Worm is a Windows PE EXE file. Once inside the victim’s computer, it goes about stealing the email addresses from user’s address book and starts sending itself as attachments to the email-ids found. The subject and body of the mail vary as it is chosen randomly from a list.
“The earlier versions of Scano and similar types, used to spread via injecting script worms through Internet Explorer vulnerabilities,” says Arti Taru, Assistant Manager, R&D, MicroWorld Technologies. “But this one takes the email route and can claim large number of victims as it nicks email addresses from the victim’s computer. Well, if a normal user receives an email from his friend, carrying a rather harmless looking “HTA’ attachment, I don’t see a reason why he should be apprehensive about opening it!”
At the next level, Scano.e logs on to various pre-decided websites and downloads more dangerous Trojans and Backdoors without the knowledge of the user. Such backdoors can even turn your computer to a remote-controlled bot, via IRC channels.
“The modus operandi of many new breeds of malware, is to find a foothold in your computer in the first place, using a small piece of malware code. Then it moves on to downloading more harmful stuff from specific websites. Some of them can upgrade to a higher degree of threat while some others can mutate to become different breed altogether with the newly acquired components,” explains Govind Rammurthy, CEO, MicroWorld Technologies.
With the nature of online threats changing so rapidly, it’s becoming increasingly difficult to assign a specific threat level for a particular Virus or worm. An otherwise low-threat worm can become lethal, if used in a targeted attack, in a coordinated fashion.
