TinyCheck – Stalkerware detection tool

The security experts at Kaspersky has affirmed that TinyCheck allows the users to capture network communications from a smartphone or any device connected to a Wi-Fi access point in a series to analyze them instantly.

Users can also go with another option, and according to the experts, that are the best choice to perform; the user can use a Raspberry Pi (3+) with a Wi-Fi dongle and a small touch screen. This short configuration easily allows the user to tap anywhere on the screen of the Wi-Fi device.

What is Stalkerware?

Stalkerware is a term that refers to a diversity of harmful programs and apps that are meant to stalk you. The primary aim of Stalkerware is to strengthen the exchange between organizations working to resist domestic violence and abuses that are perpetrated by exploiting technology.

Stalkerware involves keystroke loggers, location monitoring apps, invasive email, text readers, and remote access features that can take command of your webcam and microphone. 

Initial idea

The initial idea was to produce a tiny kiosk device based on Raspberry Pi, which can be utilized by non-tech people to test their smartphones against ill-disposed communications that are issued by a stalker and any spyware.

Not only this, but TinyCheck can also be utilized to spot any malicious communications from cybercrime or state-sponsored implants.


TinyCheck can be practiced in several ways by individuals, and here are the uses mentioned below:-

  • Over a network – TinyCheck is installed on a network and can be obtained from a workstation through a browser.
  • In kiosk mode – TinyCheck can be utilized as a kiosk to enable visitors to test their own devices.
  • Fully standalone – By using a power bank, you can touch any device anywhere.

This open-source tool is simple to use as it is based on the Raspberry Pi. The TinyCheck examines the traffic coming out of a mobile device and recognizes interactions with known ill-disposed sources, like the spyware-related servers. 

But, here, the main motive of TinyCheck is to assist non-profit organizations, such as service providers, support victims of domestic violence to defend them and preserve their secrecy and privacy.

You can find the complete details of the tools and the code in GitHub.
