Group Policy Preferences
Adversaries may attempt to find unsecured credentials in Group Policy Preferences (GPP). GPP are tools that allow administrators to create domain policies with embedded credentials. These policies allow administrators to set local accounts.(Citation: Microsoft GPP 2016) These group policies are stored in SYSVOL on a domain controller. This means that any domain user can view the SYSVOL share and

Exfiltration Over Asymmetric Encrypted Non-C2 Protocol
Adversaries may steal data by exfiltrating it over an asymmetrically encrypted network protocol other 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. Asymmetric encryption algorithms are those that use different keys on each end of the channel. Also known as public-key cryptography, this r
Cloud Account
Adversaries may attempt to get a listing of cloud accounts. Cloud accounts are those created and configured by an organization for use by users, remote support, services, or for administration of resources within a cloud service provider or SaaS application.
With authenticated access there are several tools that can be used to find accounts. The Get-MsolRoleMember
PowerShell cmdlet c
Process Discovery
Adversaries may attempt to get information about running processes on a system. Information obtained could be used to gain an understanding of common software/applications running on systems within the network. Adversaries may use the information from [Process Discovery](https://attack.mitre.org/techniques/T1057) during automated discovery to shape follow-on behaviors, including whether or not the
Impair Command History Logging
Adversaries may impair command history logging to hide commands they run on a compromised system. Various command interpreters keep track of the commands users type in their terminal so that users can retrace what they've done.
On Linux and macOS, command history is tracked in a file pointed to by the environment variable HISTFILE
. When a user logs off a system, this information is
Launchd
Adversaries may abuse the Launchd
daemon to perform task scheduling for initial or recurring execution of malicious code. The launchd
daemon, native to macOS, is responsible for loading and maintaining services within the operating system. This process loads the parameters for each launch-on-demand system-level daemon from the property list (plist) files found in /S
Windows Management Instrumentation Event Subscription
Adversaries may establish persistence and elevate privileges by executing malicious content triggered by a Windows Management Instrumentation (WMI) event subscription. WMI can be used to install event filters, providers, consumers, and bindings that execute code when a defined event occurs. Examples of events that may be subscribed to are the wall clock time, user loging, or the computer's uptime.
CDNs
Adversaries may search content delivery network (CDN) data about victims that can be used during targeting. CDNs allow an organization to host content from a distributed, load balanced array of servers. CDNs may also allow organizations to customize content delivery based on the requestor’s geographical region. Adversaries may search CDN data to gather actionable information. Threat actors can
