A quick Google didn't yield much for "canary passwords", but it sounds like monitoring for passwords as opposed to user email/details as described in the OP. Care to shed a bit more light on what you mean here and how to effectively use them?

I think he’s referring to the idea of having fake users in your database whose passwords should never be used to sign in. Someone successfully signing in with one of those accounts indicates that your user account credentials have been compromised.

Yep. It's either fake users, or weak passwords for existing users.

Another name for that is backdoor.

I did similar project with Tensorflow. Mouse movements were captured then converted to images and DL model was trained to classify user or not user. It can also classify classes of users I.e. new portal users are moving mouse differently from users who are familiar with portal. To add - by itself it’s not a reliable indicator of yes/no. But rather another risk scoring input to overall identity detection system.

This is actually clever. Thanks for sharing the technique!

Pleasure :) Here's writeup:

There's value here in detection of a breach that's already been monetized, but this isn't in the kill chain; it's long-after, so it appears reactive-only. Why should a non-massive company implement this rather than boosting and refining centralized logging and monitoring which can, if done right, provide far more immediate (even real time) notification of a breach? Your Wells Fargos of the world might do it because t…

Any measures can miss the breach. For example disgruntled insider admin quietly stole all users data on his last day at work.

Properly calibrated monitoring should catch that scenario with near certainty though.

Somewhat related, but anyone have any best practices or can recommend a service to protect your users who have been pwned in another sites data breach? Rate limiting login attempts for an email address or ip address is all well and good for protecting against brute force attacks, but when the attacker has the correct email and password combination already for the user, and access to massively distributed botnets, how…

It looks like something that Distil [1] is doing, among other things. AFAIK they will be expanding this functionality in the coming months.

Disclaimer: My company have been using Distil for a few months; mainly for detecting and blocking bots, but they provide a range of other security features.
