Honeytoken

A honey token is a fake data entry placed inside a real dataset to detect theft — if the decoy ever gets used, it confirms the data has been compromised.

About this video

Detecting data theft is one of the more difficult challenges in cybersecurity, particularly when the stolen information consists of common fields like names and email addresses that offer no obvious signal of compromise. A honey token addresses this problem by introducing a fabricated record into a real dataset — one that looks legitimate but serves solely as a trap. Because the decoy entry has no authentic business purpose, any interaction with it is a strong indicator that the surrounding data has been stolen and is being actively used. The technique works by pairing false identifying details, such as a fictitious name and company, with a real, monitored asset like a dedicated email address controlled by the security team. If an attacker steals the dataset and uses it — for example, in a phishing or marketing campaign — they will inevitably contact that address. Since it appears nowhere else, receiving any message there confirms the breach and provides a concrete, time-stamped signal that the data has left the organization. This gives security teams a detection mechanism that requires no complex tooling, only a carefully placed piece of bait.

Would We Even Know the Data Was Stolen?

Hopefully no one breaks into our network and ever steals anything from our network. But if they do, we want some way to recognize that that data has been stolen and be able to track that data. There is actually a mechanism that can help us do that.

Let's develop a little scenario here. Let's say we have a database, and in this database we have first name, last name, the company they work for and their email address. These are some company customers that we have right here. But it was stolen: this database is stolen. How would we even know if a database is stolen or not? That becomes a problem, to recognize when these names have been stolen. I mean, this is pretty generic information right here, so it's quite conceivable that we would never know that this database had been stolen.

Planting a Honey Token

A honey token could help us identify if this information gets stolen or not. What we've entered here is another entry into this database. It has some sort of fake company with a fake first name and a fake last name, and then an email address which is not fake. This is actually an email address that we own that will actually come back to us if you email this address right here.

What can happen here is, if somebody steals this information, what are they stealing it for? They might be marketing towards these people right here, and they might be using their email address. If they send to this email address, this is the only place this email address is used. So if we start getting mail to this right here, we know that this information has been stolen. We might not know any other way that this information was stolen until we start getting emails at this email address.
