Detects deletion of an Amazon Bedrock guardrail, which may indicate attempts to remove
model safety controls and allow unsafe or unauthorized model responses.
model safety controls and allow unsafe or unauthorized model responses.
Detects the load of RstrtMgr DLL (Restart Manager) by an uncommon process.
This library has been used during ransomware campaigns to kill processes that would prevent file encryption by locking them (e.g. Conti ransomware, Cactus ransomware). It has also recently been seen used by the BiBi wiper for Windows.
It could also be used for anti-analysis purposes by shut downing specific processes.

Detects failed attempts to clear Windows event logs via the WMI NTEventLogFile ClearEventLog method.
Event 5858 in the WMI-Activity operational log is an error event, meaning it is only generated
when the WMI operation encounters an error (e.g. access denied, provider failure).
It could be an indication of an attacker attempting to clear event logs via WMI, but failing due to insufficient privileges or other issues.
Successful clearing operations will NOT produce this event; for those, correlate with
Security event 1102 or System event 104.

Detection for when multi factor authentication has been disabled, which might indicate a malicious activity to bypass authentication mechanisms.
Detects the usage of SystemSettingsAdminFlows.exe to disable Windows Defender.
SystemSettingsAdminFlows.exe is a legitimate Windows component used for administrative configuration tasks.
However, attackers may abuse it to disable Windows Defender as part of their attack chain, especially in the context of ransomware or other malware campaigns.

Detects the addition of firewall address objects on a Fortinet FortiGate Firewall.
Detects installation of NalDrv or PROCEXP152 services via registry-keys to non-system32 folders.
Both services are used in the tool Ghost-In-The-Logs (https://github.com/bats3c/Ghost-In-The-Logs), which uses KDU (https://github.com/hfiref0x/KDU)

Detects the addition of a new firewall policy on a Fortinet FortiGate Firewall.
Detects the creation of the PROCEXP152.sys file in the application-data local temporary folder.
This driver is used by Sysinternals Process Explorer but also by KDU (https://github.com/hfiref0x/KDU) or Ghost-In-The-Logs (https://github.com/bats3c/Ghost-In-The-Logs), which uses KDU.

Detects the use of SysmonEnte, a tool to attack the integrity of Sysmon
Detects suspicious execution of Sysinternals PsSuspend, where the utility is used to suspend critical processes such as AV or EDR to bypass defenses
Detects suspicious Windows Defender Application Control (WDAC) policy file creation from abnormal processes that could be abused by attacker to block EDR/AV components while allowing their own malicious code to run on the system.
Detects the usage of the 'SeLoadDriverPrivilege' privilege. This privilege is required to load or unload a device driver.
With this privilege, the user can dynamically load and unload device drivers or other code in to kernel mode.
This user right does not apply to Plug and Play device drivers.
If you exclude privileged users/admins and processes, which are allowed to do so, you are maybe left with bad programs trying to load malicious kernel drivers.
This will detect Ghost-In-The-Logs (https://github.com/bats3c/Ghost-In-The-Logs) and the usage of Sysinternals and various other tools. So you have to work with a whitelist to find the bad stuff.

Detects the removal of Sysmon, which could be a potential attempt at defense evasion
Detects updates to Sysmon's configuration. Attackers might update or replace the Sysmon configuration with a bare bone one to avoid monitoring without shutting down the service completely
Detects potential tampering with Windows Defender settings such as adding exclusion using wmic
Detects the usage of wmic.exe to modify Windows registry via the WMI StdRegProv class write methods (CreateKey, DeleteKey, SetStringValue, etc.).
This behaviour could be potentially suspicious because it uses an alternative method to modify registry keys instead of legitimate registry tools like reg.exe or regedit.exe.
Attackers specifically choose this technique to evade detection and bypass security monitoring focused on traditional registry modification commands.

Detects uninstallation or termination of security products using the WMIC utility
UFW Disable Attempt
Sigma
Detects attempts to disable the Uncomplicated Firewall (UFW) on Linux systems.
UFW is a popular firewall management tool that provides an easy-to-use interface for configuring firewall rules.
Disabling UFW can leave a system vulnerable to attacks, as it may allow unauthorized access to network services and resources.

Detects the clearing or configuration tampering of EventLog using utilities such as "wevtutil", "powershell" and "wmic".
This technique were seen used by threat actors and ransomware strains in order to evade defenses.

Detects the removal of system firewall rules. Adversaries may only delete or modify a specific system firewall rule to bypass controls limiting network usage or access.
Detection rules that match only on the disabling of firewalls will miss this.
