Containing compromised credentials using deception systems

1. A computer-implemented method, comprising:

receiving, at a honeypot, a request to authenticate an opaque credential, wherein the honeypot is part of a honeypot fleet implemented in a network;

determining that the request comprises context information, wherein the context information correlates the opaque credential with one or more network components that are part of the network;

identifying a protected host of one or more protected hosts in the network associated with the opaque credential;

authenticating the opaque credential by validating the opaque credential with the protected host based on the context information;

determining, by the honeypot and based on the validating of the opaque credential with the protected host, that the opaque credential is compromised, and in response: logging an alert indicating a presentation of a legitimate credential to the honeypot in association with an attack;

concealing the compromise of the opaque credential;

deactivating the opaque credential in the network; and

transmitting one or more instructions to one or more other honeypots in the honeypot fleet to (a) treat the opaque credential as valid and (b) gather attack telemetry data from a lateral movement associated with the attack, the attack telemetry data comprising one or more attack mechanisms used by the attack and one or more targets sought by the attack.

2. The computer-implemented method of claim 1 , wherein

the request is received from an attacker,

the request is part of the attack, and

the context information indicates that the attack is directed against the protected host.

3. The computer-implemented method of claim 2 , further comprising:

transmitting another alert to one or more other honeypots in the network indicating that the opaque credential has been compromised; and

transmitting an instruction to the one or more other honeypots to treat the opaque credential as valid as part of the lateral movement of the attack.

the context information comprises domain metadata, and

the domain metadata comprises at least one domain identity, and

the at least one domain identity is associated with one or more domain controllers.

transmitting a notification to a honeypot management system indicating that the opaque credential has been compromised.

6. The computer-implemented method of claim 1 , wherein

a network component of the one or more network components comprises a domain.

7. The computer-implemented method of claim 2 , wherein

authenticating and deactivating the opaque credential comprises accessing an application programming interface (API) or a custom agent executing on the honeypot.

8. The computer-implemented method of claim 1 , wherein

the context information comprises data to determine a credential store, an authentication mechanism, an application, a host, or another system that the opaque credential was intended to be used against or be valid for.

9. A non-transitory computer readable storage medium comprising program instructions executable to:

receive, at a honeypot, a request to authenticate an opaque credential, wherein the honeypot is part of a honeypot fleet implemented in a network;

identify a protected host of one or more protected hosts in the network associated with the opaque credential;

authenticate the opaque credential by validating the credential with the protected host based on the context information;

determine, by the honeypot and based on the validating of the opaque credential with the protected host, that the opaque credential is compromised, and in response to: log an alert indicating a presentation of a legitimate credential to the honeypot in association with an attack;

conceal the compromise of the opaque credential;

deactivate the opaque credential in the network; and

transmit one or more instructions to one or more other honeypots in the honeypot fleet to (a) treat the opaque credential as valid and (b) gather attack telemetry data from a lateral movement associated with the attack, the attack telemetry data comprising one or more attack mechanisms used by the attack and one or more targets sought by the attack.

10. The non-transitory computer readable storage medium of claim 9 , wherein

the request is received from an attacker,

the request is part of the attack,

the context information indicates that the attack is directed against the protected host,

the context information comprises domain metadata,

the domain metadata comprises at least one domain identity, and

the at least one domain identity is associated with one or more domain controllers.

11. The non-transitory computer readable storage medium of claim 10 , further comprising:

transmitting another alert to one or more other honeypots in the network indicating that the opaque credential has been compromised;

transmitting an instruction to the one or more other honeypots to treat the opaque credential as valid as part of the lateral movement of the attack; and

transmitting a notification to a honeypot management system indicating that the opaque credential has been compromised.

12. The non-transitory computer readable storage medium of claim 9 , wherein

a network component of the one or more network components comprises a domain.

13. The non-transitory computer readable storage medium of claim 10 , wherein

authenticating and deactivating the opaque credential comprises accessing an application programming interface (API) or a custom agent executing on the honeypot.

14. The non-transitory computer readable storage medium of claim 9 , wherein

the context information comprises data to determine a credential store, an authentication mechanism, an application, a host, or another system that the opaque credential was intended to be used against or be valid for.

15. A system comprising:

one or more processors; and

a memory coupled to the one or more processors, wherein the memory stores program instructions executable by the one or more processors to:

receive, at a honeypot, a request to authenticate an opaque credential, wherein the honeypot is part of a honeypot fleet implemented in a network;

determine that the request comprises context information, wherein the context information correlates the opaque credential with one or more network components that are part of the network;

identify a protected host of one or more protected hosts in the network associated with the opaque credential;

authenticate the opaque credential by validating the credential with the protected host based on the context information;

determine, by the honeypot and based on the validating of the opaque credential with the protected host, that the opaque credential is compromised, and in response: log an alert indicating a presentation of a legitimate credential to the honeypot in association with an attack;

conceal the compromise of the opaque credential;

deactivate the opaque credential in the network; and

transmit one or more instructions to one or more other honeypots in the honeypot fleet to (a) treat the opaque credential as valid and (b) gather attack telemetry data from a lateral movement associated with the attack, the attack telemetry data comprising one or more attack mechanisms used by the attack and one or more targets sought by the attack.
