Shash consists of a downloader and a data stealing trojan. The downloader was spread in multiple email messages on 7th of November 2003. When activated, it downloads and runs the executable file that is a data stealing trojan.
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.
The downloader was distributed in multiple emails on 7th of November, 2003. The file name of the downloader is:
photo0001.asp.scr
When the downloader is run by a user, it downloads and activates an executable file from an account on phpwebhosting.com server.The downloaded file is a data stealing trojan based on the code that can be found in Mimail.C worm. When activated, the trojan copies itself as NETSPACE32.EXE file to Windows folder and creates a startup key for its file in the Registry:
[HKLM\Software\Microsoft\Windows\CurrentVersion\Run] "NetSpace32" = "%windir%\netspace32.exe"
where %windir% is a Windows folder.The trojan stays in Windows memory and monitors open application windows. When a certain window is found, the trojan gets certain information from it, saves it to C:\TMP2993.TMP file and then sends this file to 2 email addresses that are hardcoded in the trojan's body.
