Honeypot Credential Validation for Lateral Movement Prevention

Solution Overview

Problem

Existing honeypot systems struggle to validate and deactivate compromised credentials, particularly opaque credentials, which are often encrypted or hashed, making it difficult to prevent malicious attackers from using these credentials for lateral movement within a network.

Innovation Solution

A method and system for containing compromised credentials using deception systems, where a honeypot receives authentication requests, correlates context information with network components, validates credentials with protected hosts, and deactivates them, while also transmitting alerts and instructions to other honeypots to treat compromised credentials as valid, thereby stopping lateral movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If honeypots log authentication attempts but take no secondary action, then the system maintains simplicity and avoids false positives, but compromised credentials cannot be deactivated in time to prevent lateral movement

Engineering Contradiction:

Improvecredential compromise detection reliabilityVSAvoidtime to deactivate compromised credentials

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary validation of credentials against protected hosts before the attacker can use them for lateral movement. When a honeypot receives an authentication request, it validates the credential with the actual protected host in advance, and if compromised, deactivates it before the attacker can exploit it elsewhere in the network.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes feedback loops where honeypots communicate with protected hosts and other honeypots to share credential compromise information. When a credential is validated as compromised at one honeypot, this information is fed back to other honeypots and the protected host to enable coordinated deactivation and prevent further exploitation.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the system validates plaintext credentials through manual log review, then compromised plaintext credentials can be deactivated, but opaque credentials (encrypted, hashed) cannot be validated

Engineering Contradiction:

Improvecredential validation easeVSAvoidcredential type coverage

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system uses protected hosts as intermediaries to validate opaque credentials. Instead of attempting to directly validate encrypted or hashed credentials at the honeypot (which would require complex decryption/hash-comparison infrastructure), the honeypot forwards the credential to the actual protected host, which performs the validation using its existing authentication mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The protected hosts perform self-validation of credentials presented by attackers. Each protected host uses its own authentication infrastructure to validate credentials independently, eliminating the need for the honeypot system to implement complex credential validation logic for different credential types.

Inventive Principle:

Principle #25Self-service

3Reliability

If honeypots treat all authentication requests as deceptive, then they maintain their deception function, but they cannot distinguish between legitimate and malicious credential usage for validation purposes

Engineering Contradiction:

Improvehoneypot deception reliabilityVSAvoidcredential legitimacy detection difficulty

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

Instead of trying to prove that a credential is malicious (which would require complex analysis), the system inverts the approach by attempting to prove legitimacy through validation. If a credential successfully validates against a protected host, it is marked as compromised and deactivated. This inversion simplifies the detection logic while maintaining honeypot deception.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

Disclosed herein are methods, systems, and processes for containing compromised credentials using deception systems. A request to authenticate a credential is received at a honeypot and a determination is made that the request includes context information that correlates the credential with network components that are part of the network. A protected host in the network associated with the credential is identified and the credential is authenticated by validating the credential with the protected host. A determination is made that the credential is compromised and the credential is deactivated.
