![]() When our canary token is accessed, the notification for the specific token will include this note to help us identify the token. The last section allows us to enter a note that we can use to identify this particular token. For now, we’ll enter an email address to receive a notification. This can allow us to tie our existing security devices and automatically block IP and quarantine breached devices. Next, we can enter the email address that will get notified whenever the Word document is accessed.įor advanced users, we can also use a webhook to generate an API call. For our first example, we’re going to generating a Canary token as a Word document. The first thing you’ll do is select the kind of token you want to generate. We’ll start off by generating a new token from. Let’s set up a few canary tokens and watch them in action. The essential advantage here is that you can monitor real systems for breaches, essentially turning your entire network into a huge honeypot. Unlike honeypots, which are virtual systems that attract would-be attackers into interaction with a fake production system- Canary tokens are files that are placed on real systems strategically throughout the network. By setting up unique tokens for the different devices or segments in your network, you’ll immediately know what part of your network is compromised so you can begin your threat response. When they open the file with the embedded Canary token – a web beacon goes off, alerting you of the source IP, token name, and when the file got accessed. When a breach occurs, an attacker will typically transfer the targeted data on the device in the least intrusive way. The idea is to make them look like something an attacker would try to access and place them on various devices throughout our network, like a client’s laptop, NAS drive, or web server. In this article, we’ll cover Canary tokens in detail and demonstrate how you can set these up on your network to start threat hunting.Ĭanary Tokens are decoys that can take on many different forms, including Word files, a folder, PDFs, URLs, images, and many more. When Canary tokens get spread across systems in your networks, they act as traps that would-be attackers can get tripped. When the file gets opened, a GET request from the user alerts you that somebody has accessed your file. Whereby tokens are regular, everyday files like Word or PDFs with hidden web beacons embedded inside. This allows marketing and analytics companies to track user activity by knowing when that file was clicked on or used.Ĭanary tokens use this old concept of web beaconing for threat hunting. Web beacons are transparent files embedded on web pages or emails that trigger a GET request from the user that interacts with them. ![]() You may not be familiar with web beacons, but chances are you interact with them every day and don’t even know it. ![]()
