Technical Details

When an infected document is opened, the virus first decrypts itself, infects the global template and encrypts back. Further the virus replicates in all opened documents.

During the infection of the global template Antisocial.E drops two files on the root of C: drive. The first file C:\SS.BAS contains the encrypted virus code. The second file C:\SS.VBS is a Visual Basic Script. If executed it will open MS Word Application and will infect it by adding its code from the SS.BAS file. Visual Basic Script can be run if WSH (Windows Script Host) is installed. This is by default in Windows 98. To ensure that the Visual Basic Script is executed the virus changes Windows registry on such a way that next time when the computer is rebooted it will infect MS Word. After disinfection of the macro virus it is important to remove the SS.BAS file and the Visual Basic Script SS.VBS as well. Otherwise the virus will reinfect the system from the dropper C:\SS.VBS.

The encrypted part of the virus code contains also Melissa like code. First time when the virus infects a system it sends a message using MS Outlook Application to first 60 recipients listed in each users address book. The message looks as follow:

From: (name of infected user)
Subject: Important Message From (name of infected user)
Body: "Look what I found..."
To: (60 names from alias list)
Attachments: Active infected document

After that Antisocila.E changes Windows registry settings inserting a key "Sixtieth Skeptic" with a value "Where's Jamie?". Later it checks this value and do not spreads via email anymore on the same system.

Currently there is no reports for this virus to be in the wild.
