Detects network connections, process command-line executions, and email URL info matching known APT28 (Swallowtail, HOOKEDGE, LegionRelay) indicators of compromise, including specific IP addresses and GUIDs.

Detects an agentic AI application (e.g., Claude Code, ChatGPT Codex) directly
spawning a package manager install command (npm install / pip install). As enterprise
adoption of agentic coding and automation tools spreads beyond developer workstations into
marketing, HR, finance, and operations, these tools autonomously pull open-source packages
from npm and PyPI on behalf of non-developer users. CrowdStrike reports poisoned packages
(e.g., 131 AI framework packages by STARDUST CHOLLIMA, 300+ dependencies in a single day by
ALTERED SPIDER) are increasingly pulled into environments this way, giving adversaries a path
to endpoints that never had traditional developer tooling scrutiny.

Detects network connections to known Indicators of Compromise (IOCs) associated with the TraderTraitor campaign, including trojanized Terraform providers (FLATROOF/ROOFDECK malware families) using specific domains and URL paths.

Sweeps Defender XDR telemetry for known NEBULA / KNTRAT indicators (SHA256 hashes, C2 IP, decoy domain and URLs, burner publisher emails). Hash matching is scoped per table (execution hash only in process events), noisy tooling is excluded from command-line matches, network hits are limited to connection events, and results are aggregated per device and IOC.
Detects when a device connects to a wireless network SSID that has not been observed in the baseline over the previous 14 days.
Detects creation of sitecustomize.py, usercustomize.py, or .pth path configuration files inside a site-packages or dist-packages directory by a python or pip process. These files are automatically loaded by Python's site module on every subsequent interpreter start, allowing a malicious package installer to establish persistence that re-executes on every future Python invocation without further victim interaction.
The following analytic detects DNS queries to domains associated with known remote access software such as AnyDesk, GoToMyPC, LogMeIn, and TeamViewer. This detection is crucial as adversaries often use these tools to maintain access and control over compromised environments. Identifying such behavior is vital for a Security Operations Center (SOC) because unauthorized remote access can lead to data breaches, ransomware attacks, and other severe impacts if these threats are not mitigated promptly.

Sweeps DNS, endpoint network and proxy/firewall telemetry for BraZetsu C2, panel and shop domains using exact or subdomain matching. The apex installscenter.com remains active on Cloudflare with wildcard certificates.
Detects anomalous process execution and loopback network activity associated with the Model Context Protocol (MCP) 'exec_in_session' method. This pattern indicates an adversary potentially abusing the AI coding assistant's MCP server capabilities to execute arbitrary commands as a C2 channel.
Detects crontab modifications or suspicious command execution spawned by the cron daemon on macOS devices, indicating potential persistence or scheduled task abuse.
Detects the creation or modification of Python configuration files (.pth, sitecustomize.py, usercustomize.py) within site-packages or dist-packages directories when not initiated by recognized Python package managers. Such files can be abused to achieve arbitrary code execution upon Python interpreter startup, a common method for persistence or local privilege escalation in Python environments.
Detects the usage of command-line flags in AI coding assistant CLIs (such as Claude Code, Amazon Q CLI, and others) that intentionally skip security permissions, bypass approvals, or disable sandbox protections. The rule identifies potential developer activity that may inadvertently reduce the security posture of the development environment.
Detects endpoint connections to known DarkSword/Coruna exploit-host and C2 infrastructure. The shared AWS IP is only matched on C2 ports 8881/8882 to reduce collateral hits.
Detects known MacOS security bypass techniques that may be used to enable malicious code execution.
Specifically monitors for attempts to remove the com.apple.quarantine attribute using xattr, or to disable Gatekeeper protections via spctl --master-disable, both of which can allow untrusted or malicious applications to execute without standard system safeguards.
