Dropped file seen in connection with other malware

Drops PE files

Drops PE files to the application program directory (C:\ProgramData)

Entry point lies outside standard sections

Found a high number of Window / User specific system calls (may be a loop to detect user behavior)

Found dropped PE file which has not been started or loaded

Installs a raw input device (often for capturing keystrokes)

May sleep (evasive loops) to hinder dynamic analysis

PE file contains sections with non-standard names

Program does not show much activity (idle)

Uses 32bit PE files

Uses code obfuscation techniques (call, push, ret)

Description:	Adversaries may abuse command and script interpreters to execute commands, scripts, or binaries. These interfaces and languages provide ways of interacting with computer systems and are a common feature across many different platforms. Most systems come with some built-in command-line interface and scripting capabilities, for example, macOS and Linux distributions include some flavor of Unix Shell while Windows installations include the Windows Command Shell and PowerShell .
Tactics:	Execution
Data Sources:	Command: Command Execution, Module: Module Load, Process: Process Creation, Process: Process Metadata, Script: Script Execution
Platforms:	Azure AD, Google Workspace, IaaS, Linux, macOS, Network, Office 365, Windows

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
Data Sources:	File: File Creation, File: File Modification, Module: Module Load, Process: Process Creation
Platforms:	Windows
Url:	Open detailed description by Mitre

Description:	Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation. This may include manipulating file metadata, tricking users into misidentifying the file type, and giving legitimate task or service names.
Tactics:	Defense Evasion
Data Sources:	Command: Command Execution, File: File Metadata, File: File Modification, Image: Image Metadata, Process: OS API Execution, Process: Process Creation, Process: Process Metadata, Scheduled Job: Scheduled Job Metadata, Scheduled Job: Scheduled Job Modification, Service: Service Creation, Service: Service Metadata

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
Data Sources:	Command: Command Execution, Process: OS API Execution, Process: Process Creation
Platforms:	Linux, macOS, Windows

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:	Command: Command Execution, File: File Creation, File: File Metadata, Module: Module Load, Process: OS API Execution, Process: Process Creation, Script: Script Execution, WMI: WMI Creation, Windows Registry: Windows Registry Key Creation

Description:	Adversaries may use methods of capturing user input to obtain credentials or collect information. During normal system usage, users often provide credentials to various different locations, such as login pages/portals or system dialog boxes. Input capture mechanisms may be transparent to the user (e.g. Credential API Hooking ) or rely on deceiving the user into providing input into what they believe to be a genuine service (e.g. Web Portal Capture ).
Tactics:	Collection, Credential Access
Data Sources:	Driver: Driver Load, File: File Modification, Process: OS API Execution, Process: Process Creation, Process: Process Metadata, Windows Registry: Windows Registry Key Modification
Platforms:	Linux, macOS, Network, Windows

Description:	An adversary may gather the system time and/or time zone from a local or remote system. The system time is set and stored by the Windows Time Service within a domain to maintain time synchronization between systems and services in an enterprise network.
Tactics:	Discovery
Data Sources:	Command: Command Execution, Process: OS API Execution, Process: Process Creation
Platforms:	Network, Windows

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:	Command: Command Execution, Firewall: Firewall Enumeration, Firewall: Firewall Metadata, Process: OS API Execution, Process: Process Creation
Platforms:	Azure AD, Google Workspace, IaaS, Linux, macOS, Office 365, SaaS, Windows

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:	Command: Command Execution, Process: OS API Execution, Process: Process Creation

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.
