Detects suspicious file creations within the Palo Alto Networks PAN-OS' parent telemetry folder, specifically looking for filenames containing patterns indicative of OS command injection attempts related to CVE-2024-3400. These files are processed by the 'dt_curl' script, which can lead to arbitrary command execution if device telemetry is enabled and filenames are crafted to bypass shell-subprocess restrictions.
Detects the creation of Python path configuration files (.pth) within Python library folders on Windows systems. These files can be maliciously used for code execution and persistence, as modules referenced by them are executed at every Python startup (v3.5+), regardless of whether they are imported by the calling script. The rule specifically targets files ending with '.pth' in paths matching '\(venv|python(.+)?)\lib\site-packages\', while filtering out known legitimate .pth files like 'pywin32.pth' and 'distutils-precedence.pth'.
Detects the creation of Python path configuration files (.pth) within Python library folders on macOS. These files can be maliciously used for code execution and persistence, as modules referenced by them are executed at every Python startup (v3.5+), regardless of whether they are explicitly imported by a script. The rule specifically looks for files ending with '.pth' in the '/lib/python3.([5-9]|[0-9]{2})/site-packages/' directory structure.
Detects the creation of Python path configuration files (.pth) within Python library folders on Linux systems. These files can be maliciously used for code execution and persistence, as modules referenced by them are executed at every Python startup (v3.5+), regardless of whether they are imported by the calling script. The rule specifically looks for files ending with '.pth' in typical Python site-packages directories.
Detects potential exploitation attempts of CVE-2024-3400, an OS command injection vulnerability in Palo Alto GlobalProtect. The rule looks for suspicious strings indicating directory traversal or command injection within Palo Alto GlobalProtect logs.
Detects the execution of 'netscan.exe' from SoftPerfect, a network scanning application. This tool is frequently used by threat actors for network reconnaissance to map out network architecture within compromised environments.
This rule detects the use of PowerShell in conjunction with nslookup to create a download cradle. This technique leverages nslookup to extract payloads from DNS TXT records, which are then processed by PowerShell. This is a known method for adversaries to download malicious content while potentially evading traditional network defenses by using DNS for data transfer.
Detects when a request to the Kubernetes API is rejected due to lack of authorization or due to an expired authentication token being used. This may indicate an attacker attempting to leverage credentials they have obtained.
Detects command line patterns associated with the use of Pnscan for sending and receiving binary data across the network. This behavior has been identified in a Linux malware campaign targeting Docker, Apache Hadoop, Redis, and Confluence and was previously used by the threat actor known as TeamTNT.
Detects the installation of the AnyDesk remote access software service. This could indicate abuse if AnyDesk is not legitimately used within the environment. The rule specifically looks for Event ID 7045 from the 'Service Control Manager' provider, where the service name or image path contains 'AnyDesk' and the service name also contains 'Service'.
