github.com/SpyGuard/SpyGuard @v2.1

[!IMPORTANT] Version 2 finally emerged after two years devoted to my family, marking a return to the project after an extended period away. An update of Suricata introduced breaking changes in the detection mechanism; version 2 addresses these changes while further enhancing the detection of suspicious network flows. You can see changes between the V1 and the V2 in this PR description.

Description

SpyGuard's main objective is to detect signs of compromise by monitoring network flows transmitted by a device.

As it uses WiFi, SpyGuard can be used against a wide range of devices, such as smartphones, laptops, IOTs or workstations. To do its job, the analysis engine of SpyGuard is using Indicators of Compromise (IOCs), anomaly detection and is supported by Suricata.

Examples of use cases

Note: SpyGuard is not a forensic tool. Therefore, it might miss malware that does not communicate during the analysis. Please refer to the FAQ for more information.

Installation

You need a debian-like operating system to install it easly by using the provided bash script. Once you've cloned the repository, just launch install.sh as root. Here are the command lines to do that:

cd /tmp/ && git clone https://github.com/SpyGuard/spyguard
cd spyguard && sudo bash install.sh

Once installed, you can go to the backend interface located at https://localhost:8443 to manage the device and setup the right network interfaces to get it working. Please look at the dedicated wiki page to get some tips regarding it.

[!WARNING] Please check prior the installation that your Linux distribution is using nmcli to manage networks. Old Raspberry Pi operating systems require activation of nmcli the raspi-config interface prior Spyguard installation (See here).

The frontend is available at the URL https://localhost:8000.

Smartphone analysis best practices

• Do the interception in a public place (library, restaurant, train station...) or common place (office, home...);
• Intercept the network communications of the device for at least 30 minutes;
• Interact with the analysed device during the interception (reboot it, take a photo, send an SMS...);

SpyGuard and Stalkerware threat

The indicators of compromise (IOCs) linked to stalkerware are now fully managed by ECHAP, a French association working against cyberviolence. Even though stalkerware still remains a threat, remember that most of digital violence and surveillance is done by using simple means, such as hacking cloud & mail accounts. Therefore, we encourage you to consult the ECHAP guides and apply their advice to your digital life alongside of device checks.

[!IMPORTANT] It is worth mentioning that the IOCs are distributed under the Creative Common BY-NC-SA licence. This imply a non commercial use of them. Please respect this licence and ask ECHAP for any question related to that.

Commercial use

You can use SpyGuard in a commercial product. However, you can't use SpyGuard as the name of your product and you’re still required to follow the terms and conditions that the Apache License imposes, like refering to the SpyGuard project in customer documentation.
