Automatic action

Once the scan is complete, the F-Secure security product will ask if you want to uninstall the file, move it to the quarantine or keep it installed on your device.

Suspect a file is incorrectly detected (a False Positive)?

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.

Technical Details

Chuli.A is an information stealing trojan that was used in a targeted attack involving a Tibetan activist and several other high-profile human rights activists.

Chuli.A arrives onto a device via an installer named ‘WUCs Conference.apk’ and is installed as an application named Conference. When launched, it displays a string of text addressing several organizations.

In the background however, Chuli.A connects to a command and control (C&C) server at the IP address 64.78.161.133 to report the infection. It also collects device information and forwards the details to the server if instructed to do so via an SMS message. Collected information include:

  • Contacts data
  • GPS coordinates
  • Phone call logs
  • Stored SMS messages
