APT-C-36 is a suspected South America espionage group that has been active since at least 2018. The group mainly targets Colombian government institutions as well as important corporations in the financial sector, petroleum industry, and professional manufacturing.
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|
|T1027 - Obfuscated Files or Information||In an adversary engagement scenario, there is an opportunity to introduce decoy systems that can influence an adversary's behavior or allow you to observe how they perform a specific task.||DTE0017 - Decoy System||A defender could implement a decoy system to study how and when an adversary obfuscate files and hides information.|
|T1036 - Masquerading||There is an opportunity to detect the presence of an adversary by identifying and alerting on anomalous behaviors.||DTE0007 - Behavioral Analytics||A defender can look for known files in non-standard locations or files that are creating anomalous processes or connections.|
|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.|
|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.|
|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.|
|T1571 - Non-Standard Port||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.|
