Technical Details

Counterclank.A is an advertising module included in various apps, typically popular games or image-related programs. The apps themselves are not malicious and are free, ad-supported software that simply included the advertising module to provide revenue for the app developers.

In addition to displaying ads however, the module also leaks information from the device to a remote site without the user's knowledge.

While the app is running, the module retrieves the following information from the device and forwards the data to http://[...][...]:

  • Device manufacturer
  • Device model
  • Device version
  • IMEI (International Mobile Equipment Identity) number
  • Operating system version
  • Phone locale settings
  • Phone number
  • Source IP address
  • User Agent

The module also adds a search icon to the device's home screen and a bookmark to the device's browser, which lead the user to a mobile search provider, http://[...][...].

While apps with such behavior may be legitimately used by the device's authorized user, they are classified by security programs as riskware because in the hands of unauthorized users, they can also be used to cause damage to the user's data or the device.

If you are confident that you are aware of the risks involved in using the program and consent to its use, you may choose to keep it installed on your device.
