This rule detects processes with names commonly associated with system daemons (e.g., kworker, fc-cache, chronyd, gvfsd) that are executing from non-standard, suspicious directories such as /tmp/ or user-defined hidden folders. This behavior is indicative of an adversary attempting to masquerade malicious binaries as legitimate system processes to evade detection.
This rule detects processes accessing '/proc/self/status' to read the 'TracerPID' field. Malware often uses this technique to detect if it is being debugged or traced by security analysis tools, allowing the process to terminate or change behavior to avoid analysis.

This rule detects potential web shell activity by identifying suspicious PHP file creation within Magento-style product cache directories and the execution of find commands targeted at searching for PHP files in the web directory. This behavior is indicative of an attacker attempting to plant a web shell and subsequently enumerating web files for further exploitation.
This rule detects a correlation between an email phishing burst (high volume of emails with a specific failed payment subject) and the subsequent creation of suspicious 'x_trace_' files in 'var/report/' directories. This pattern is indicative of a phishing campaign where a malicious attachment or link might be attempting to write local tracking or diagnostic files on a victim's host.

Detects abnormally long request URIs, often indicating fuzzing or buffer-overflow probing.
The following analytic detects a Python process making an outbound network connection during package installation.
Adversaries can abuse `setup.py` build scripts by leveraging `distutils`/`setuptools` command classes to execute arbitrary code, including network beacons to third-party domains, the moment a malicious Python package is installed.
This activity is significant because it allows adversaries to establish a foothold or exfiltrate data without any direct interaction from the victim beyond running `pip install`.
If confirmed malicious, this could indicate a successful software supply chain compromise.

Detects EDR or JVM stack-trace or exception telemetry indicating the invocation of insecure deserialization methods associated with Log4jLogEvent$LogEventProxy, such as marshalledMessage.get() or MarshalledObject.get(). This pattern is indicative of potential exploitation attempts leveraging vulnerable Log4j libraries for remote code execution.
This rule detects file-based activity associated with a tool named 'gh-token-monitor', which is likely used for the monitoring or exfiltration of GitHub access tokens from a compromised host. The rule monitors for the creation or presence of specific scripts, configuration files, and directory paths associated with this activity, including files related to a 'claude' configuration.
Detects the loading of Linux kernel modules using insmod or modprobe from non-standard, writable directories such as /tmp, /var/tmp, /dev/shm, /home, /root, or /opt. This behavior is highly indicative of an adversary attempting to install a malicious kernel module or rootkit to gain persistence or privilege escalation, while bypassing standard package management paths.

Detects PHP scripts that masquerade as WordPress cache classes but contain functionality for decrypting commands using AES-256-CBC and executing them via shell_exec. The detection identifies the presence of hardcoded encryption keys, use of php://input, and common PHP obfuscation/encryption methods alongside shell execution functions.
Detects unauthenticated command injection in Zimbra Collaboration (CVE-2026-73570).
The swatchdog Perl script spawns a shell that chains arbitrary commands after snmptrap,
indicating abuse of SNMP notifications via a crafted SMTP sender.

indicating abuse of SNMP notifications via a crafted SMTP sender.
Detects the creation or modification of specific files within the /tmp directory, specifically those matching naming patterns associated with 'jasper-log' files or temporary pipe files. These patterns are often associated with temporary storage or data staging activities during post-exploitation or malware execution.
Detects the modification or replacement of critical Linux system daemons (crond, sshd, polkitd, etc.) followed by a service restart or reload. This behavior is indicative of potential trojanization or unauthorized tampering of system processes to establish persistence or inject malicious code.
Detects instances where common web server applications (e.g., Apache, Tomcat, IIS, Nginx) or Java runtime environments spawn suspicious child processes like command shells (cmd.exe, powershell.exe, sh, bash) or network utilities (wget, curl). This behavior often indicates exploitation of a web vulnerability, such as Remote Code Execution (RCE), allowing an adversary to execute commands or download further malicious payloads.
Detects the creation or modification of a specific file ('libvirtlog.so.0') located in '/usr/lib/' which acts as a gating mechanism for the curlRAT malware. The detection correlates this file event with processes commonly associated with system management that are executing with command line arguments indicative of malicious activity (e.g., 'reverse', 'pty').
This rule detects either the execution of a specific SSH daemon binary known to be trojanized or the creation/modification of files within the /var/lib/sshd/ directory, which is a common indicator of backdoor persistence or credential theft targeting SSH sessions.
