Mapping To Chimera

Chimera is a suspected China-based threat group, targeting the semiconductor industry in Taiwan since at least 2018.


Disclaimer: We present this mapping to stimulate thinking about active defense options to combat this adversary, not to present all possibilities. We invite you to use this as a guide and add your own use cases for applying Shield techniques to counter each adversary action.

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

T1059 - Command and Scripting Interpreter There is an opportunity for the defender to observe the adversary and control what they can see, what effects they can have, and/or what data they can access. DTE0036 - Software Manipulation A defender can manipulate the output of system commands issued to alter information the adversary might use during their activity.
T1059 - Command and Scripting Interpreter There is an opportunity for the defender to observe the adversary and control what they can see, what effects they can have, and/or what data they can access. DTE0036 - Software Manipulation A defender can modify the functionality of commands used to delete files so that the files are copied to a safe location before they are deleted.
T1059 - Command and Scripting Interpreter There is an opportunity for the defender to observe the adversary and control what they can see, what effects they can have, and/or what data they can access. DTE0034 - System Activity Monitoring A defender can detect the presence of an adversary by monitoring for processes that are created by commands and/or scripts they execute on a system.
T1078 - Valid Accounts There is an opportunity to introduce user accounts that are used to make a system look more realistic. DTE0010 - Decoy Account A defender can create decoy user accounts which are used to make a decoy system or network look more realistic.
T1078 - Valid Accounts There is an opportunity to deploy a tripwire that triggers an alert when an adversary touches a network resource or uses a specific technique. DTE0012 - Decoy Credentials A defender can seed systems with decoy credentials in a variety of locations and establish alerting that will trigger if an adversary harvests the credentials and attempts to use them.
T1078 - Valid Accounts There is an opportunity to prepare user accounts so they look used and authentic. DTE0008 - Burn-In A defender can prepare a Decoy System by logging in to the Decoy Account and using it in ways consistent with the deception story, creating artifacts in the system that make it look legitimate.
T1087 - Account Discovery There is an opportunity for the defender to observe the adversary and control what they can see, what effects they can have, and/or what data they can access. DTE0036 - Software Manipulation A defender could alter the output from account enumeration commands to hide accounts or show the presence of accounts which do not exist.

DTE0010 - Decoy Account During an adversary engagement operation, a defender can utilize decoy accounts to provide content to an adversary and encourage additional activity.

DTE0013 - Decoy Diversity A defender can make a variety of decoy accounts and see if the adversary seems to be drawn to accounts of a specific type, with specific permissions, group access, etc.
T1102 - Web Service There is an opportunity to detect the presence of an adversary by identifying and alerting on anomalous behaviors. DTE0007 - Behavioral Analytics A defender can detect the use of external web services for communication relay. By implementing behavior analytics anomalies in what domains a system is communicating with, how frequently, and at what times, a defender can potentially identify malicious traffic.
T1105 - Ingress Tool Transfer There is an opportunity to collect network data and analyze the adversary activity it contains. DTE0028 - PCAP Collection Collecting full packet capture of all network traffic allows you to review what happened over the connection and identify command and control traffic and/or exfiltration activity.
