Summary
On January 25th a new backdoor known as Sadhound has been spammed in emails with subject 'I Miss You'. Sadhound is not a worm and does not spread by itself.
Removal
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.
Technical Details
Sadhound drops a text file in Windows Temp folder and opens it with Notepad. The text looks as follow:
There's no special reason for sending this to you, except that... I was feeling a little lonely, and when I asked myself what I seemed to bemissing the most,the answerturned out to be ...you. I Miss You
F-Secure Anti-Virus detects Sadhound with the existing updates as a dropper.
