CISA issues guidance on cyber decoy strategies

CISA released guidance helping defenders use decoys, honeytokens, and tripwires to detect living-off-the-land attacker activity.

CISA has published defensive guidance describing how organizations can deploy cyber decoys—including tripwires, breadcrumbs, and honeytokens—to improve detection and response capabilities, particularly against adversaries using legitimate credentials, native tools, and living-off-the-land (LOTL) techniques. The document targets organizations at varying levels of cybersecurity maturity and frames decoy strategies as a complement to Zero Trust architectures, under the assumption that adversaries may already have gained some foothold in the environment.

The guidance leverages the MITRE Engage and MITRE ATT&CK frameworks to provide low-complexity, practical steps for planning, implementing, and refining decoy operations. Stated benefits include supporting continuous monitoring and verification, generating high-fidelity alerts for suspicious activity, reducing alert fatigue, and improving detection of post-compromise activity such as discovery and lateral movement performed via LOTL techniques.

This is a methodology and best-practices resource rather than an advisory about a specific vulnerability, campaign, or active threat. There are no IOCs, CVEs, named threat actors, or malware associated with this publication. Defenders interested in improving detection of credential misuse and LOTL activity may use this as a planning reference alongside CISA's related MITRE ATT&CK mapping guidance.
