Technique ID: T1114.002
Name: Email Collection: Remote Email Collection
Description: Adversaries may target an Exchange server, Office 365, or Google Workspace to collect sensitive information. Adversaries may leverage a user's credentials and interact directly with the Exchange server to acquire information from within a network. Adversaries may also access externally facing Exchange serv...
Tactics: Collection
Platforms Affected: Google Workspace, Office 365, Windows
Detection Strategies: Monitor for unusual login activity from unknown or abnormal locations, especially for privileged accounts (ex: Exchange administrator account).

Technique ID: T1048
Name: Exfiltration Over Alternative Protocol
Description: Adversaries may steal data by exfiltrating it over a different protocol than that of the existing command and control channel. The data may also be sent to an alternate network location from the main command and control server. Alternate protocols include FTP, SMTP, HTTP/S, DNS, SMB, or any other network p...
Tactics: Exfiltration
Platforms Affected: Google Workspace, IaaS, Linux, Network, Office 365, SaaS, Windows, macOS
Detection Strategies: Analyze network data for uncommon data flows (e.g., a client sending significantly more data than it receives from a server). Processes utilizing the network that do not normally have network communication or have never been seen before are suspicious. Analyze packet contents to detect communicati...

Technique ID: T1567
Name: Exfiltration Over Web Service
Description: Adversaries may use an existing, legitimate external Web service to exfiltrate data rather than their primary command and control channel. Popular Web services acting as an exfiltration mechanism may give a significant amount of cover due to the likelihood that hosts within a network are already communicat...
Tactics: Exfiltration
Platforms Affected: Google Workspace, Linux, Office 365, SaaS, Windows, macOS
Detection Strategies: Analyze network data for uncommon data flows (e.g., a client sending significantly more data than it receives from a server). Processes utilizing the network that do not normally have network communication or have never been seen before are suspicious. User behavior monitoring may help to detect a...

Technique ID: T1567.004
Name: Exfiltration Over Web Service: Exfiltration Over Webhook
Description: Adversaries may exfiltrate data to a webhook endpoint rather than over their primary command and control channel. Webhooks are simple mechanisms for allowing a server to push data over HTTP/S to a client without the need for the client to continuously poll the server. Many public and commercial services, s...
Tactics: Exfiltration
Platforms Affected: Google Workspace, Linux, Office 365, SaaS, Windows, macOS
Detection Strategies: No detection description provided.

Technique ID: T1537
Name: Transfer Data to Cloud Account
Description: Adversaries may exfiltrate data by transferring the data, including backups of cloud environments, to another cloud account they control on the same service to avoid typical file transfers/downloads and network-based exfiltration detection. A defender who is monitoring for large transfers to outside the cl...
Tactics: Exfiltration
Platforms Affected: IaaS
Detection Strategies: Monitor account activity for attempts to share data, snapshots, or backups with untrusted or unusual accounts on the same cloud service provider. Monitor for anomalous file transfer activity between accounts and to untrusted VPCs. In AWS, sharing an Elastic Block Store (EBS) snapshot, either with ...

Technique ID: T1531
Name: Account Access Removal
Description: Adversaries may interrupt availability of system and network resources by inhibiting access to accounts utilized by legitimate users. Accounts may be deleted, locked, or manipulated (ex: changed credentials) to remove access to accounts. Adversaries may also subsequently log off and/or perform a System Shu...
Tactics: Impact
Platforms Affected: Linux, Office 365, SaaS, Windows, macOS
Detection Strategies: Use process monitoring to monitor the execution and command line parameters of binaries involved in deleting accounts or changing passwords, such as use of Net. Windows event logs may also designate activity associated with an adversary's attempt to remove access to an account: Event ID 4723 - An...

Technique ID: T1485
Name: Data Destruction
Description: Adversaries may destroy data and files on specific systems or in large numbers on a network to interrupt availability to systems, services, and network resources. Data destruction is likely to render stored data irrecoverable by forensic techniques through overwriting files or data on local and remote driv...
Tactics: Impact
Platforms Affected: Containers, IaaS, Linux, Windows, macOS
Detection Strategies: Use process monitoring to monitor the execution and command-line parameters of binaries that could be involved in data destruction activity, such as SDelete. Monitor for the creation of suspicious files as well as high unusual file modification activity. In particular, look for large quantities of...

Technique ID: T1486
Name: Data Encrypted for Impact
Description: Adversaries may encrypt data on target systems or on large numbers of systems in a network to interrupt availability to system and network resources. They can attempt to render stored data inaccessible by encrypting files or data on local and remote drives and withholding access to a decryption key. This m...
Tactics: Impact
Platforms Affected: IaaS, Linux, Windows, macOS
Detection Strategies: Use process monitoring to monitor the execution and command line parameters of binaries involved in data destruction activity, such as vssadmin, wbadmin, and bcdedit. Monitor for the creation of suspicious files as well as unusual file modification activity. In particular, look for large quantitie...

Technique ID: T1491
Name: Defacement
Description: Adversaries may modify visual content available internally or externally to an enterprise network, thus affecting the integrity of the original content. Reasons for Defacement include delivering messaging, intimidation, or claiming (possibly false) credit for an intrusion. Disturbing or offensive images ma...
Tactics: Impact
Platforms Affected: IaaS, Linux, Windows, macOS
Detection Strategies: Monitor internal and external websites for unplanned content changes. Monitor application logs for abnormal behavior that may indicate attempted or successful exploitation. Use deep packet inspection to look for artifacts of common exploit traffic, such as SQL injection. Web Application Firewalls ...

Technique ID: T1491.002
Name: Defacement: External Defacement
Description: An adversary may deface systems external to an organization in an attempt to deliver messaging, intimidate, or otherwise mislead an organization or users. External Defacement may ultimately cause users to distrust the systems and to question/discredit the system’s integrity. Externally-facing websites are ...

Technique ID: T1499
Name: Endpoint Denial of Service
Description: Adversaries may perform Endpoint Denial of Service (DoS) attacks to degrade or block the availability of services to users. Endpoint DoS can be performed by exhausting the system resources those services are hosted on or exploiting the system to cause a persistent crash condition. Example services include ...
Tactics: Impact
Platforms Affected: Azure AD, Containers, Google Workspace, IaaS, Linux, Office 365, SaaS, Windows, macOS
Detection Strategies: Detection of Endpoint DoS can sometimes be achieved before the effect is sufficient to cause significant impact to the availability of the service, but such response time typically requires very aggressive monitoring and responsiveness. Typical network throughput monitoring tools such as netflow, ...
