Detection

Score:	4
Range:	0 - 100
Whitelisted:	false
Confidence:	60%

Signatures

Allocates memory with a write watch (potentially for evading sandboxes)

Contains long sleeps (>= 3 min)

May sleep (evasive loops) to hinder dynamic analysis

Program does not show much activity (idle)

Queries the volume information (name, serial number etc) of a device

Sample execution stops while process was sleeping (likely an evasion)

Sample file is different than original file name gathered from version info

Uses code obfuscation techniques (call, push, ret)

Description:	Adversaries may execute their own malicious payloads by side-loading DLLs. Similar to DLL Search Order Hijacking , side-loading involves hijacking which DLL a program loads. But rather than just planting the DLL within the search order of a program then waiting for the victim application to be invoked, adversaries may directly side-load their payloads by planting then invoking a legitimate application that executes their payload(s).
Tactics:	Defense Evasion, Persistence, Privilege Escalation

Description:	Adversaries may modify and/or disable security tools to avoid possible detection of their malware/tools and activities. This may take many forms, such as killing security software processes or services, modifying / deleting Registry keys or configuration files so that tools do not operate properly, or other methods to interfere with security tools scanning or reporting information. Adversaries may also disable updates to prevent the latest security patches from reaching tools on victim systems.
Tactics:	Defense Evasion
Data Sources:	Command: Command Execution, Driver: Driver Load, Process: Process Creation, Process: Process Termination, Sensor Health: Host Status, Service: Service Metadata, Windows Registry: Windows Registry Key Deletion, Windows Registry: Windows Registry Key Modification

Description:	Adversaries may employ various means to detect and avoid virtualization and analysis environments. This may include changing behaviors based on the results of checks for the presence of artifacts indicative of a virtual machine environment (VME) or sandbox. If the adversary detects a VME, they may alter their malware to disengage from the victim or conceal the core functions of the implant. They may also search for VME artifacts before dropping secondary or additional payloads. Adversaries may use the information learned from [Virtualization/Sandbox Evasion](https://attack.mitre.org/techniques/T1497) during automated discovery to shape follow-on behaviors.
Tactics:	Defense Evasion, Discovery

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.

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.
