Palo Alto Cortex XDR

341 rules · Sigma detections in Palo Alto Cortex XDR syntax
The same Sigma detection corpus, machine-rendered into Palo Alto Cortex XDR query syntax and ready to paste. Switch platforms above for identical coverage in another language, or choose Sigma (generic) for the portable YAML.
Severity critical high medium low all severities
Using these Sigma rules
Deploy. Pick your SIEM above and paste the rendered query straight into a saved search or detection rule, or expand any rule to convert its generic YAML inline to the language you run.
Adapt. Map the field names to your log schema - Sigma assumes a normalised taxonomy - and tune thresholds and timeframes to your own baseline before you trust the alert.
Validate. Every rule is mapped to ATT&CK, so run the matching Atomic Red Team test on /atomic to confirm the rule actually fires before you rely on it.

Potential Azure Browser SSO Abuse
Detects abusing Azure Browser SSO by requesting OAuth 2.0 refresh tokens for an Azure-AD-authenticated Windows user (i.e. the machine is joined to Azure AD and a user logs in with their Azure AD account) wanting to perform SSO authentication in the browser. An attacker can use this to authenticate to Azure AD in a browser as that user.

Potential Executable Run Itself As Sacrificial Process
Detects when an executable launches an identical instance of itself, a behavior often used to create a suspended “sacrificial” process for code injection or evasion. Investigate for indicators such as the process being started in suspended mode, rapid parent termination, memory manipulation (e.g., WriteProcessMemory, CreateRemoteThread), or unsigned binaries. Review command-line arguments, process ancestry, and network activity to confirm if this is legitimate behavior or process injection activity.

During exploitation of this vulnerability, two logs (Provider_Name: Microsoft-Windows-User Profiles Service) with EventID 1511 and 1515 are created (EventID 1515 may generate many false positives). Additionally, the directory \Users\TEMP may be created during exploitation. This behavior was observed on Windows Server 2008.

Potential File Override/Append Via SET Command
Detects the use of the "SET" internal command of Cmd.EXE with the /p flag followed directly by an "=" sign. Attackers used this technique along with an append redirection operator ">>" in order to update the content of a file indirectly. Ex: cmd /c >> example.txt set /p="test data". This will append "test data" to contents of "example.txt". The typical use case of the "set /p=" command is to prompt the user for input.

Potential Proxy Execution Via Explorer.EXE From Shell Process
Detects the creation of a child "explorer.exe" process from a shell like process such as "cmd.exe" or "powershell.exe". Attackers can use "explorer.exe" for evading defense mechanisms by proxying the execution through the latter. While this is often a legitimate action, this rule can be use to hunt for anomalies. Muddy Waters threat actor was seeing using this technique.

Potentially Suspicious Long Filename Pattern - Linux
Detects the creation of files with unusually long filenames (100 or more characters), which may indicate obfuscation techniques used by malware such as VShell. This is a hunting rule to identify potential threats that use long filenames to evade detection. Keep in mind that on a legitimate system, such long filenames can and are common. Run this detection in the context of threat hunting rather than alerting. Adjust the threshold of filename length as needed based on your environment.

Privileged Container Deployed
Detects the creation of a "privileged" container, an action which could be indicative of a threat actor mounting a container breakout attacks. A privileged container is a container that can access the host with all of the root capabilities of the host machine. This allows it to view, interact and modify processes, network operations, IPC calls, the file system, mount points, SELinux configurations etc. as the root user on the host. Various versions of "privileged" containers can be specified, e.g. by setting the securityContext.privileged flag in the resource specification, setting non-standard Linux capabilities, or configuring the hostNetwork/hostPID fields

Python Image Load By Non-Python Process
Detects the image load of "Python Core" by a non-Python process. This might be indicative of a execution of executable that has been bundled from Python code. Various tools like Py2Exe, PyInstaller, and cx_Freeze are used to bundle Python code into standalone executables. Threat actors often use these tools to bundle malicious Python scripts into executables, sometimes to obfuscate the code or to bypass security measures.

RBAC Permission Enumeration Attempt
Detects identities attempting to enumerate their Kubernetes RBAC permissions. In the early stages of a breach, attackers will aim to list the permissions they have within the compromised environment. In a Kubernetes cluster, this can be achieved by interacting with the API server, and querying the SelfSubjectAccessReview API via e.g. a "kubectl auth can-i --list" command. This will enumerate the Role-Based Access Controls (RBAC) rules defining the compromised user's authorization.
