Disassembly

⊘No disassembly

Description:	Adversaries may directly interact with the native OS application programming interface (API) to execute behaviors. Native APIs provide a controlled means of calling low-level OS services within the kernel, such as those involving hardware/devices, memory, and processes.These native APIs are leveraged by the OS during system boot (when other system components are not yet initialized) as well as carrying out tasks and requests during routine operations.
Tactics:	Execution
Data Sources:	API monitoring, Loaded DLLs, Process monitoring, System calls
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may modify access tokens to operate under a different user or system security context to perform actions and bypass access controls. Windows uses access tokens to determine the ownership of a running process. A user can manipulate access tokens to make a running process appear as though it is the child of a different process or belongs to someone other than the user that started the process. When this occurs, the process also takes on the security context associated with the new token.
Tactics:	Defense Evasion, Privilege Escalation
Data Sources:	API monitoring, Access tokens, Authentication logs, Process command-line parameters, Process monitoring, Windows event logs
Platforms:	Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit. This is common behavior that can be used across different platforms and the network to evade defenses.
Tactics:	Defense Evasion
Data Sources:	Binary file metadata, Email gateway, Environment variable, File monitoring, Malware reverse engineering, Network intrusion detection system, Network protocol analysis, Process command-line parameters, Process monitoring, Process use of network, SSL/TLS inspection, Windows event logs
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may attempt to get a listing of security software, configurations, defensive tools, and sensors that are installed on a system or in a cloud environment. This may include things such as firewall rules and anti-virus. Adversaries may use the information from Security Software Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
Tactics:	Discovery
Data Sources:	AWS CloudTrail logs, Azure activity logs, File monitoring, Process command-line parameters, Process monitoring, Stackdriver logs
Platforms:	AWS, Azure, Azure AD, GCP, Linux, macOS, Office 365, SaaS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system. Adversaries may use the information from File and Directory Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
Tactics:	Discovery
Data Sources:	File monitoring, Process command-line parameters, Process monitoring
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture. Adversaries may use the information from System Information Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
Tactics:	Discovery
Data Sources:	AWS CloudTrail logs, Azure activity logs, Process command-line parameters, Process monitoring, Stackdriver logs
Platforms:	AWS, Azure, GCP, Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	An adversary may compress and/or encrypt data that is collected prior to exfiltration. Compressing the data can help to obfuscate the collected data and minimize the amount of data sent over the network. Encryption can be used to hide information that is being exfiltrated from detection or make exfiltration less conspicuous upon inspection by a defender.
Tactics:	Collection
Data Sources:	Binary file metadata, File monitoring, Process command-line parameters, Process monitoring
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may collect data stored in the clipboard from users copying information within or between applications.
Tactics:	Collection
Data Sources:	API monitoring
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may employ a known encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Despite the use of a secure algorithm, these implementations may be vulnerable to reverse engineering if secret keys are encoded and/or generated within malware samples/configuration files.
Tactics:	Command and Control
Data Sources:	Malware reverse engineering, Netflow/Enclave netflow, Packet capture, Process monitoring, Process use of network, SSL/TLS inspection
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may communicate using application layer protocols to avoid detection/network filtering by blending in with existing traffic. Commands to the remote system, and often the results of those commands, will be embedded within the protocol traffic between the client and server.
Tactics:	Command and Control
Data Sources:	DNS records, Netflow/Enclave netflow, Network protocol analysis, Packet capture, Process monitoring, Process use of network
Platforms:	Linux, macOS, Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may shutdown/reboot systems to interrupt access to, or aid in the destruction of, those systems. Operating systems may contain commands to initiate a shutdown/reboot of a machine. In some cases, these commands may also be used to initiate a shutdown/reboot of a remote computer.Shutting down or rebooting systems may disrupt access to computer resources for legitimate users.
Tactics:	Impact
Data Sources:	Process command-line parameters, Process monitoring, Windows event logs
Platforms:	Linux, macOS, Windows
