Wootbot represents the growing family of backdoors - hacker's remote access tools. These tools allow to contol victims' computers remotely by sending specific commands to them. Also these backdoors can steal data and spread to computers vulnerable to exploits. In addition Wootbot is capable of working as a proxy and can use strong encryption of its connections. This variant of Wootbot contains the new MYSQL exploit.


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.

CAUTION Manual disinfection is a risky process; it is recommended only for advanced users.

Manual disinfection for Wootbot backdoor requires renaming of an infected file, usually located in Windows or Windows System folder and restarting a system. Please note that the backdoor's file may have read-only, system and hidden attributes, so Windows Explorer has to be configured to show such files.

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.

When active, the backdoor starts an FTP server on a random port.

The backdoor can be controlled remotely and do any of the below:

- start socks4/5 proxy
- start http proxy
- scan/exploit for vulnerabilities
- ping flood
- open command shell
- download/execute files

The backdoor contains the following scanners/exploits:

- ipc (remote shares), port 139
- mssql (Microsoft SQL servers), port 1433
- mysql, port 3306
