This rule detects the creation or modification of email forwarding or redirection rules within Microsoft 365 audit logs. It specifically looks for operations related to 'UpdateInboxRules', 'Set-Mailbox', 'New-InboxRule', and 'Set-InboxRule' that include parameters indicative of forwarding or redirecting emails, such as 'Forward', 'Recipients', 'ForwardingSmtpAddress', 'ForwardingAddress', 'ForwardAsAttachmentTo', 'ForwardTo', 'RedirectTo', and 'RedirectToRecipients'. This activity can be a sign of an attacker attempting to exfiltrate sensitive information from a compromised mailbox or maintain persistence.
Detects when an application (service principal) is assigned Azure AD roles, such as global administrator, or Azure RBAC roles, such as subscription owner. This activity can indicate privilege escalation or persistence by an attacker who has compromised an application.
Detects potential RDP Session Hijacking activity on Windows systems
Detects usage of system utilities such as "find", "tree", "findmnt", etc, to discover files, directories and network shares.
Detects remote thread creation in the "mstsc.exe" process by a process located in a potentially suspicious location.
This technique is often used by attackers in order to hook some APIs used by DLLs loaded by "mstsc.exe" during RDP authentications in order to steal credentials.

Detects the execution of SharpMove, a .NET utility performing multiple tasks such as "Task Creation", "SCM" query, VBScript execution using WMI via its PE metadata and command line options.
Detects suspicious processes spawned from a Java host process which could indicate a sign of exploitation (e.g. log4j)
Detects the load of the Windiver driver, a powerful user-mode capture/sniffing/modification/blocking/re-injection package for Windows
Detects suspicious use of PCHunter, a tool like Process Hacker to view and manipulate processes, kernel options and other low level stuff
Detects the use of NPS, a port forwarding and intranet penetration proxy server
