T1112 - Modify Registry
Description from ATT&CK (opens in a new tab)
Adversaries may interact with the Windows Registry as part of a variety of other techniques to aid in defense evasion, persistence, and execution.
Access to specific areas of the Registry depends on account permissions, with some keys requiring administrator-level access. The built-in Windows command-line utility Reg (opens in a new tab) may be used for local or remote Registry modification.(Citation: Microsoft Reg) Other tools, such as remote access tools, may also contain functionality to interact with the Registry through the Windows API.
The Registry may be modified in order to hide configuration information or malicious payloads via Obfuscated Files or Information (opens in a new tab).(Citation: Unit42 BabyShark Feb 2019)(Citation: Avaddon Ransomware 2021)(Citation: Microsoft BlackCat Jun 2022)(Citation: CISA Russian Gov Critical Infra 2018) The Registry may also be modified to Impair Defenses (opens in a new tab), such as by enabling macros for all Microsoft Office products, allowing privilege escalation without alerting the user, increasing the maximum number of allowed outbound requests, and/or modifying systems to store plaintext credentials in memory.(Citation: CISA LockBit 2023)(Citation: Unit42 BabyShark Feb 2019)
The Registry of a remote system may be modified to aid in execution of files as part of lateral movement. It requires the remote Registry service to be running on the target system.(Citation: Microsoft Remote) Often Valid Accounts (opens in a new tab) are required, along with access to the remote system's SMB/Windows Admin Shares (opens in a new tab) for RPC communication.
Finally, Registry modifications may also include actions to hide keys, such as prepending key names with a null character, which will cause an error and/or be ignored when read via Reg (opens in a new tab) or other utilities using the Win32 API.(Citation: Microsoft Reghide NOV 2006) Adversaries may abuse these pseudo-hidden keys to conceal payloads/commands used to maintain persistence.(Citation: TrendMicro POWELIKS AUG 2014)(Citation: SpectorOps Hiding Reg Jul 2017)

Atomic Test #72 - Setting Shadow key in Registry for RDP Shadowing
Microsoft Remote Desktop Protocol (RDP) supports a “shadowing” feature and RDP is available in all Windows Server Operating Systems and the business editions of end-user Windows versions. In order to use the RDP shadowing feature, the Remote Desktop Services (TermService) service needs to be running (which it does by default), a rule needs to be enabled in the Windows Firewall and in case of stealth reasons, a setting needs to be configured to not prompt the user for permission when they are being shadowed. In order to configure RDP shadowing session in a quiet mode. The registry of a remote system can be updated using several protocols, depending on the accessible ports and configuration of the services listening on those ports. Our aim is to set the Shadow value in HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services on the remote machine to 2, which allows us to both view and control the session without the user being informed.

Atomic Test #90 - Adding custom paths for application execution
As per Microsoft,the entries found under App Paths are used primarily to map an application’s executable file name to that file’s fully qualified path and to pre-pend information to the PATH environment variable on a per-application, per-process basis. The path can be modified to load a custom application of choice. Post the registry changes of this test, when someone tries to manually run msedge.exe via StartMenu/Run window , notepad will be launched.
