Elderwood is a suspected Chinese cyber espionage group that was reportedly responsible for the 2009 Google intrusion known as Operation Aurora. The group has targeted defense organizations, supply chain manufacturers, human rights and nongovernmental organizations (NGOs), and IT service providers.
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.|
|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.|
|T1189 - Drive-by Compromise||There is an opportunity to study the adversary and collect first-hand observations about them and their tools.||DTE0017 - Decoy System||A defender can use a decoy system to access a compromised website to see how it works (study the exploit sequence, collect relevant artifacts, etc.).|
|T1189 - Drive-by Compromise||There is an opportunity to discover who or what is being targeting by an adversary.||DTE0013 - Decoy Diversity||A defender could use a decoy or set of decoys with different network addresses, operating systems, web browsers, language settings, and etc. to determine if every system that visits a compromised website receives its malicious payload or only specific systems receive it.|
|T1189 - Drive-by Compromise||There is an opportunity to use a compromised drive-by site to start long term engagement with the adversary and observe the adversary's post-exploit TTPs.||DTE0014 - Decoy Network||A defender seeking to learn about post compromise adversary activity could visit the compromised website with a system in a decoy network that has been designed to sustain an adversary engagement past the initial compromise.|
|T1195 - Supply Chain Compromise||Hardware and/or software additions can be tested and verified in controlled environments prior to deployment.||DTE0014 - Decoy Network||A defender can install any suspect hardware or software on an isolated system or network and monitor for non-standard behaviors.|
|T1203 - Exploitation for Client Execution||There is an opportunity to study the adversary and collect first-hand observations about them and their tools.||DTE0017 - Decoy System||A defender can use a decoy system to see if an adversary exploits vulnerable software in order to compromise the system.|
|T1203 - Exploitation for Client Execution||There is an opportunity to discover who or what is being targeting by an adversary.||DTE0004 - Application Diversity||A defender can install one or more applications on a decoy system with a variety of patch levels to see how an adversary might exploit those applications.|
|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.|
