FARMIGTON HILLS – When you get an email from Anna, Alice or Ellyn saying that she loves you and offers you a password to open her heart, don?t get carried away. The encrypted zipped file is a Bagle worm.

Security Analysts at MicroWorld Technologies reported that “Win32.Bagle.fy” comes via password protected ZIP archives attached to spammed emails with a variety of sender names and subject lines.

The subject of the mail is the name of a person chosen from a list that carries common ones like Alice, Andrew, Androw, Annes, Christean, Dorothy ,Edmond and many more. The mail body reads ?I love you? and shows an image of the randomly generated numeric password next to it. The worm employs its own SMTP engine to proliferate, spreading fast in United States, Europe and South Asia.

?It?s always a tendency of the human psyche to open up a protected secret and nobody knows it better than the Virus writer,? said Govind Rammurthy, CEO, MicroWorld Technologies. ?Now when you club that penchant with a message that says ?I love you?, coming from a rather common name, the whole thing adds up to the temptation and smoothly gets you into its vicious design. This is smart Social Engineering with a heady mix of emotional ploys.?

With its password protected encryption, ?Bagle.fy? evades detection by security solutions at the Gateway provided by some popular AntiVirus firms. After finding an entry into the computer, the worm connects to many websites and downloads much more malicious stuff in the true tradition of Bagle family.

The Bagle family known for its innovation, fast mutation and adaptability has been hugely menacing and dangerous for enterprise security over last few years. These mass mailing worms coming in a wide variety of size, spite and modes of proliferation, have been advancing really fast into deadly Trojans that are even equipped with Rootkit capabilities. An earlier variant named Bagle.GE, carried a Rootkit component which hid the registry keys of another member, Bagle.GF.
