Command Shell Activity Started via RunDLL32
2 rules 4 TTPsThis rule detects command shell activity, such as cmd.exe or powershell.exe, initiated by RunDLL32, a technique commonly abused by attackers to execute malicious code and bypass security controls.
Detection of VScode Remote Tunneling for Command and Control
2 rules 1 TTPThe rule detects the execution of the VScode portable binary with the tunnel command line option, potentially indicating an attempt to establish a remote tunnel session to Github or a remote VScode instance for unauthorized access and command and control.
Enumerating Domain Trusts via DSQUERY.EXE
2 rules 2 TTPsAdversaries may use the `dsquery.exe` command-line utility to enumerate trust relationships for lateral movement in Windows multi-domain environments.
Local Account TokenFilter Policy Modification for Defense Evasion and Lateral Movement
2 rules 4 TTPsAdversaries may modify the LocalAccountTokenFilterPolicy registry key to bypass User Account Control (UAC) and gain elevated privileges remotely by granting high-integrity tokens to remote connections from local administrators, facilitating lateral movement and defense evasion.
Potential Account Takeover - Logon from New Source IP
2 rules 1 TTPThe rule identifies a user account that normally logs in with high volume from one source IP suddenly logging in from a different source IP, potentially indicating account takeover or use of stolen credentials from a new location.
Potential Active Directory Replication Account Backdoor
2 rules 2 TTPsAttackers can modify Active Directory object security descriptors to grant DCSync rights to unauthorized accounts, creating a backdoor to extract credential data.
Potential Computer Account NTLM Relay Activity
2 rules 2 TTPsDetection of potential NTLM relay attacks targeting computer accounts by identifying authentication events originating from hosts other than the account's owner, indicating possible credential theft and misuse.
Potential Data Exfiltration via Rclone
2 rules 3 TTPsAttackers are abusing the legitimate file synchronization tool rclone, often renamed to masquerade as legitimate software, to exfiltrate data to cloud storage or remote endpoints.
Potential DLL Side-Loading via Trusted Microsoft Programs
2 rules 2 TTPsThis rule detects potential DLL side-loading attempts by identifying instances of Windows trusted programs (WinWord.exe, EXPLORER.EXE, w3wp.exe, DISM.EXE) being started after being renamed or from a non-standard path, which is a common technique to evade defenses by side-loading a malicious DLL into the memory space of a trusted process.
Potential Evasion via Windows Filtering Platform Blocking Security Software
2 rules 2 TTPsAdversaries may add malicious Windows Filtering Platform (WFP) rules to prevent endpoint security solutions from sending telemetry data, impairing defenses, which this rule detects by identifying multiple WFP block events where the process name is associated with endpoint security software.
Potential NetNTLMv1 Downgrade Attack via Registry Modification
2 rules 2 TTPsThis brief details a registry modification attack that downgrades the system to NTLMv1 authentication, enabling NetNTLMv1 downgrade attacks, typically performed with local administrator privileges on Windows systems.
Potential Pass-the-Hash (PtH) Attempt Detection
2 rules 1 TTPThis rule detects potential Pass-the-Hash (PtH) attempts in Windows environments by monitoring successful authentications with specific user IDs (S-1-5-21-* or S-1-12-1-*) and the `seclogo` logon process, where attackers use stolen password hashes to authenticate and move laterally across systems without needing plaintext passwords.
Potential Remote File Execution via MSIEXEC
2 rules 3 TTPsThe rule detects the execution of the built-in Windows Installer, msiexec.exe, to install a remote package potentially abused by adversaries for initial access and defense evasion.
Potential Secure File Deletion via SDelete Utility
2 rules 2 TTPsThis rule detects file name patterns generated by the use of Sysinternals SDelete utility, potentially used by attackers to delete forensic indicators and hinder data recovery efforts.
Potential WPAD Spoofing via DNS Record Creation
2 rules 1 TTPDetection of a Windows DNS record creation event (5137) with an ObjectDN attribute containing 'DC=wpad', which indicates a potential WPAD spoofing attack to enable privilege escalation and lateral movement.
Potential WSUS Abuse for Lateral Movement via PsExec
2 rules 2 TTPsAdversaries may exploit Windows Server Update Services (WSUS) to execute PsExec for lateral movement within a network by abusing the trusted update mechanism to run signed binaries.

SIP Provider Modification for Defense Evasion
2 rules 1 TTPThis rule detects modifications to the registered Subject Interface Package (SIP) providers, which are used by the Windows cryptographic system to validate file signatures, potentially indicating an attempt to bypass signature validation or inject code for defense evasion.
