A worm that spreads via email, usually in infected executable email file attachments.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
Email-Worm:MSIL/Agent.MXK attempts to spread using several different methods (email, autorun, P2P and network-worm). It will also try to connect to an IRC-channel to get further instructions that include stealing CD-keys for several different games or performing a DOS attack.
When executed, the worm copies itself to:
Creates the following launchpoint so that the worm is executed when the infected system is started:
Creates two distinct mutexes among others
Miscellaneous functionality:
The worm will attempt to join the channel #botland1 on irc.afterworkchat.net to receive instructions from the attacker. The command include retrieving keys for the following games:
Spreads as an autorun worm using the file name ntldr.com.
Spreads as an email worm faking the sender address to the name of the Windows user account and uses one of the following domain names:
emails will be sent to addresses in the Outlook address book. The subject of the email will be "Hi" and the mail body will be "WoW, WTF?!"
The worm will try to copy itself to other computers on the network by trying to guess the username and password using a short list of different common passwords (e.g., 123, root, admin).
The worm will copy itself to the shared folder of several different file-sharing applications, affected programs are:
The following are the file names that the worm may use:
The worm is not very stable and probably in many cases, only the first steps of copying the file to the two locations, and creating registry keys are successfully performed.
