An informant (or snitch) is someone from inside a network recruited by an adversary to provide information on the network.
An informant can be used by an adversary to find evidence or to achieve network mapping.
There are several different recruitment strategies: targeting people on the periphery of a network who are less committed, people who may face deportation if they don't cooperate, people who have been charged with another crime and are offered leniency or immunity in exchange of their cooperation, people who are no longer in a network and harbor feelings of resentment, people who prioritize money over dignity, etc.
Informants recruited by the State are often referred to as “confidential sources” in court proceedings.
See the informants topic.

Mitigations
| Name | Description |
|---|---|
| Attack | You can attack informants when uncovered or years later to discourage others from becoming informants. |
| Background checks | You can perform background checks to help ensure that someone in your network is not an informant. |
| Need-to-know principle | You can apply the need-to-know principle to limit the information a potential informant has about your involvement in actions (if an informant isn't involved in an action, they shouldn't know who was involved even if it's their own roommate). |
| Network map exercise | You can conduct a network map exercise to help ensure your network does not place trust in people who could become informants. |
| Prisoner support | You can support prisoners from your networks: beyond the ethical imperative of this support, people are less likely to turn informant if they feel supported and connected to the movements for which they risked their freedom. |

| Case against Marius Mason | The main evidence against Marius Mason was provided to investigators by his former husband, Frank Ambrose, who had participated in some of the actions with him[1]. Frank Ambrose became an informant after his arrest in 2007 (which was triggered by him throwing incriminating material in a garbage can)[2]. For several months, the snitch collaborated extensively with the Federal Bureau of Investigation (FBI), secretly recording 178 phone conversations and face-to-face meetings, and providing information on 15 people[3]. |
