Rancor is a threat group that has led targeted campaigns against the South East Asia region. Rancor uses politically-motivated lures to entice victims to open malicious documents.
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.
ATT&CK Technique | Opportunity Space | AD Technique | Use Case |
---|---|---|---|
T1053 - Scheduled Task/Job | There is an opportunity to study the adversary and collect first-hand observations about them and their tools. | DTE0001 - Admin Access | A defender can enable Admin Access on a system to see if the adversary utilizes that access to create scheduled tasks to launch their malware or tools. |
T1053 - Scheduled Task/Job | There is an opportunity to study the adversary and collect first-hand observations about them and their tools. | DTE0017 - Decoy System | A defender can configure a decoy system with limited restrictions to see if the adversary creates or alters scheduled tasks to launch their malware. |
T1053 - Scheduled Task/Job | There is an opportunity to create a detection with a moderately high probability of success. | DTE0034 - System Activity Monitoring | A defender can capture system activity logs and generate alerts if the adversary creates new scheduled tasks or alters existing tasks. |
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. |
T1071 - Application Layer Protocol | There is an opportunity to monitor network traffic for different protocols, anomalous traffic patterns, transfer of data, etc. to determine the presence of an adversary. | DTE0027 - Network Monitoring | The defender can implement network monitoring for and alert on anomalous traffic patterns, large or unexpected data transfers, and other activity that may reveal the presence of an adversary. |
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. |
T1204 - User Execution | There is an opportunity to study the adversary and collect first-hand observations about them and their tools. | DTE0018 - Detonate Malware | A defender can execute adversary malware on a decoy system and examine its behaviors or potentially engage with the adversary to obtain further intelligence. |
T1218 - Signed Binary Proxy Execution | There is an opportunity to block an adversary's intended action and force them to reveal additional TTPs. | DTE0036 - Software Manipulation | A defender can monitor operating system functions calls to look for adversary use and/or abuse. |
T1218 - Signed Binary Proxy Execution | There is an opportunity to study the adversary and collect first-hand observations about them and their tools. | DTE0018 - Detonate Malware | A defender can detonate malicious code leveraging a signed binary on a decoy system or within a decoy network to see how it behaves or for adversary engagement purposes. |
T1218 - Signed Binary Proxy Execution | There is an opportunity to create a detection with a moderately high probability of success. | DTE0003 - API Monitoring | A defender can monitor and analyze operating system functions calls for detection and alerting. |
T1566 - Phishing | A phishing email can be detected and blocked from arriving at the intended recipient. | DTE0019 - Email Manipulation | A defender can intercept emails that are detected as suspicious or malicious by email detection tools and prevent deliver to the intended target. |
T1566 - Phishing | A phishing email can be detected and moved from the intended recipient to a decoy account for reading and execution. | DTE0023 - Migrate Attack Vector | A defender can move suspicious emails to a decoy system prior to opening and examining the email. |
T1566 - Phishing | Users trained and encouraged to report phishing can detect attacks that other defenses do not. | DTE0035 - User Training | A program to train and exercise the anti-phishing skills of users can create "Human Sensors" that help detect phishing attacks. |
T1566 - Phishing | There is an opportunity to discover who or what is being targeting by an adversary. | DTE0015 - Decoy Persona | A defender can seed information about the decoy persona's personal accounts on systems to see if the adversary collects and uses that information in future activity. |
