  "account": "On 16 September 2026, the Cybersecurity and Infrastructure Security Agency (CISA) released a comprehensive guide detailing the process of implementing cyber decoys to enhance detection and response capabilities in critical infrastructure environments. The guide addresses a significant challenge faced by many organizations: detecting adversaries who exploit legitimate credentials, native tools, and living-off-the-land techniques. Cyber decoys work by creating assets within a network that are likely to be targeted by an attacker, providing high-fidelity evidence of malicious exploration. Unlike honeypots, decoys are not traps designed to entrap attackers, but rather detection tools that signal when an adversary is probing the environment. The guide emphasizes that decoys are a complementary measure to Zero Trust security models, which require continuous verification of user credentials. High-value placements for decoys include credential stores, service accounts with privileged-sounding names, file shares containing sensitive documents, and administrative interfaces accessible only internally. The key to maximizing decoy effectiveness lies in their placement, as decoys that are frequently interacted with by legitimate processes can generate false positives and render the alert system ineffective. Once a decoy generates an event, the event must be routed into the existing detection pipeline with the same level of scrutiny as other high-confidence alerts. This involves defining what constitutes interaction with the decoy, enriching the alert with contextual information about the identity and asset involved, and establishing a clear response protocol. CISA aligns decoy strategies with the MITRE Engage framework and the MITRE ATT&CK matrix, enabling organizations to strategically place decoys to address specific adversary behaviors they currently lack visibility into. However, deploying decoys is not without risks. Cybersecurity teams must carefully consider the operational risks associated with decoys, such as the potential for legitimate systems to be mistakenly identified as decoys during outages or the creation of new attack paths if decoys share credentials with real infrastructure. To mitigate these risks, the guide recommends a phased approach to implementing decoys, starting with identifying the most critical adversary techniques that are currently undetected, followed by meticulous verification that the decoy placements do not mimic production systems or share credentials with legitimate infrastructure. Ongoing monitoring and documentation of the decoy inventory are crucial to maintaining the deception and ensuring that the decoys remain effective as a detection mechanism.",
