Cool: [Wayback/Archive] Canarytokens
Canary tokens are a free, quick, painless way to help defenders discover they’ve been breached (by having attackers announce themselves.)
How tokens works (in 3 short steps):
- Visit the site and get a free token (which could look like an URL or a hostname, depending on your selection.)
- If an attacker ever uses the token somehow, we will give you an out of band (email or sms) notification that it’s been visited.
- As an added bonus, we give you a bunch of hints and tools that increase the likelihood of an attacker tripping on a canary token.
The above documentation is just a small portion of what is at [Wayback/Archive] Canarytokens.org – Quick, Free, Detection for the Masses with even more documentation starting at [Wayback/Archive] Introduction | Canarytokens.
Source code (either the site or a docker image):
- site: [Wayback/Archive] thinkst/canarytokens: Canarytokens helps track activity and actions on your network.
- docker: [Wayback/Archive] thinkst/canarytokens-docker: Docker configuration to quickly setup your own Canarytokens.

I learned it at the height of the Log4Shell mitigation stress. Some related posts from that period:
