Mapping To Cleaver

Cleaver is a threat group that has been attributed to Iranian actors and is responsible for activity tracked as Operation Cleaver. Strong circumstantial evidence suggests Cleaver is linked to Threat Group 2889 (TG-2889). Disclaimer: We present this mapping to stimulate thinking about engagement activities to take advantage of the historically observed behavior of adversary, not to present all possibilities. We invite you to use this as a guide, understanding that adversary behavior is constantly changing and evolving.

Note: All ATT&CK Group sub-activity mappings have been remapped to their parent activity and were derived from Group Technique mappings in ATT&CK v8.

ATT&CK® Technique Adversary Vulnerability Engagement Activity Engagement Activity Description
OS Credential Dumping When adversaries interact with the environment or personas, they are vulnerable when they collect, observe, or manipulate system artifacts or information. Manipulated data may cause them to reveal behaviors, use additional or more advanced capabilities against the target, and/or impact their dwell time. Decoy Artifacts and Systems Introduce impersonations to expand the scope of a deceptive story.
OS Credential Dumping When adversaries interact with the environment or personas, they are vulnerable to collecting, or in some way interacting with, manipulated or decoy data. In those cases the data may increase their tolerance for imperfections in the environment and improve the overall believability of the ruse. Pocket Litter Place data on a system to reinforce the legitimacy of the system or user.
OS Credential Dumping When adversaries interact with engagement environments and personas, their future capability, targeting, and/or infrastructure requirements are vulnerable to influence. Decoy Artifacts and Systems Introduce impersonations to expand the scope of a deceptive story.
OS Credential Dumping When adversaries interact with network or system resources, they are vulnerable to triggering tripwires or engaging in easily detectable, anomalous behavior. System Activity Monitoring Collect system activity logs that can reveal adversary activity.
OS Credential Dumping When adversaries use previously stolen information to access or move laterally within an environment, they may reveal previous collection activities. Decoy Artifacts and Systems Introduce impersonations to expand the scope of a deceptive story.
OS Credential Dumping When adversaries discover enabled, accessible, or intentionally weakened/overly permissive resources in the environment, they are vulnerable to revealing additional or more advanced capabilities when exploiting or using said resource. Decoy Artifacts and Systems Introduce impersonations to expand the scope of a deceptive story.
OS Credential Dumping When adversaries collect manipulated artifacts, they are vulnerable to revealing their presence when using or moving the artifacts elsewhere in the engagement environment. Decoy Artifacts and Systems Introduce impersonations to expand the scope of a deceptive story.
Man-in-the-Middle When adversaries interact with the environment or personas, they are vulnerable when they collect, observe, or manipulate system artifacts or information. Manipulated data may cause them to reveal behaviors, use additional or more advanced capabilities against the target, and/or impact their dwell time. Decoy Artifacts and Systems Introduce impersonations to expand the scope of a deceptive story.
