Summary

A dropper Trojan that contains malicious or potentially unwanted software, which it 'drops' and installs on the affected system.

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

Binanen.A creates a dummy iexplore.exe process, and runs its malicious activity by silently dropping the following file:

  • C:\windows\system32\winimet.dll

It also copies itself to:

  • C:\windows\system32\binanen.exe

And, creates the following registry keys:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{26D37492-FEC2-C272-9882-6D97A521F122}
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{761CC820-6EC0-5921-1400-8442C1E2FB90}

Payload

Once the malware is executed, the dropped file will try to disguise itself under a true process name and will be injected into a hidden dummy process. Then, it will execute certain command lines such asipconfig, which can be used to retrieve IP address, subnet mask, and default gateway.
