A new email worm Kipis.A was found on 22th of December 2004.The worm spreads in emails that have a subject "Love", "I Love You", or "Happy New Year".
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 detection database 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.
When run the worm creates a mutex named "KiPiShx018AxR" to avoid running more than once simultaneously.
The worm copies itself as:
where %WinDir% is Windows folder, for example 'C:\Windows\' on a default installation of Windows XP. In effect, running "regedit" runs a copy of the worm instead of regedit.exe.
It also creates a directory
and copies itself in that directory as "svchost.exe". This path is added to system.ini file using the Windows API call WritePrivateProfileStringA from the Kernel32.dll. The entry will look like this:
[boot] Shell=Explorer.exe "%WinDir%\security\svchost.exe"
As win.ini is not supported by Windows NT, 2000 and XP, on these operating system the changes will be added to the Registry. As as result Windows will start the worm on every time it boots.
The worm also creates a file
where %WinSysDir% is Windows System folder, for example 'C:\Windows\System32' on a default installation of Windows XP.
The file Jpg.bmp contains the following string
BMD -:+:- zzzzzzzzzzz
Then the worm tries to open this file with mspaint.exe as a decoy. This file crashes mspaint.exe.
Kipis.A tries to locate the email addresses from the Windows address book file. Additionally, it collects addresses from files with certain extensions on all hard disks and RAM drives from C: to Z. Files with the following extensions will be checked:
.tbb .dbx .doc .htm .adb .txt
The worm has its own SMTP engine which it uses to send infected emails. The messages sent by the worm will have one of the following subjects:
I Love You Happy New Year Love
The worm uses the following body text in the message:
Hello! baby :-) It can also use the following faked error message in the body: Server cannot send message. _____________________________________________ On all questions address in a support service The worm attaches itself to an infected message using one of the following names: your present.scr foto_03.scr myfoto_04.scr trax_06.scr dom2.scr foto_05.scr
The worm spreads itself in P2P networks. When it locates a shared folder, it copies itself there with one of the following names:
Nude Britney Spears.scr Nude Pic_07.scr Virtual Girl 2.01.com KAV Pro 5.xx keygen.com DrWeb 4.32 keygen.com WinXP Sp2 key.com
Kipis.A creates a thread that terminates security related software.
The worm also has a backdoor listening on port 1029. With this backdoor, additional programs can be uploaded and executed.
