This rule detects the creation or modification of a file named 'ClipBoard.txt' within the directory 'AppData\Roaming\ConfigsEx\', as well as the creation of the 'ConfigsEx' directory using command-line tools. This behavior is indicative of an adversary staging sensitive information, such as harvested clipboard data, for potential exfiltration.

Detects unauthorized file operations (creation, modification, or renaming) against the Windows hosts file located at C:\Windows\System32\drivers\etc\hosts. This is a common technique used by attackers to redirect network traffic, hijack domains, or disrupt communications to security services. The rule excludes common system processes known to perform legitimate maintenance on this file.

Detects the execution of common Windows command-line tools (such as cmd, powershell, or wmic) being used to query system information related to security configurations, antivirus status, firewall status, or installed security products. This behavior is indicative of an adversary performing reconnaissance to understand the defensive landscape of a compromised host.

This rule detects network connections or process command lines associated with known malicious domains, IP addresses, or payload URLs. Additionally, it correlates connections to common public file-sharing platforms or APIs (e.g., Gofile, Telegram) if these events occur on the same device within a 60-minute window of a confirmed malicious infrastructure event, reducing false positives from legitimate uses of shared infrastructure.

001
This rule monitors endpoint telemetry for known indicators of compromise associated with the Casbaneiro/Ousaban banking trojan. It identifies activity across network connections (IPs and domain patterns), DNS queries for specific C2 domains, and the presence or execution of known malicious file hashes (e.g., PDF lures, HTA, AutoIt scripts, and payload binaries).

001
This rule detects the execution of arbitrary commands via the Windows Subsystem for Linux (WSL) by monitoring process creation events where 'wsl.exe' is the executable. It specifically looks for command lines that include flags like '--exec' or '-e', or common shell commands and downloaders such as 'curl', 'wget', 'bash -c', 'sh -c', 'nc ', or 'ncat '. This activity can indicate an adversary leveraging WSL to execute malicious code or bypass security controls.

This rule monitors the Windows Application event log for critical Microsoft SQL Server (MSSQL) events. It detects server crashes, access violations, stack overflows, and high-severity (20+) errors. These events often indicate severe database corruption, underlying system instability, or potential exploitation attempts targeting the database engine.

005
This rule monitors web server logs (IIS, W3C, and Azure Application Gateway) for incoming traffic that matches known malicious or automated vulnerability scanners, as well as requests for common system fingerprinting paths (such as /server-status or /.git/config). The rule aggregates these hits by source IP address to identify potential active reconnaissance or vulnerability scanning attempts.

Detects the execution of 'driverquery.exe' to enumerate information about the 'npf.sys' driver (Network Packet Filter), which is associated with Npcap/WinPcap used for packet capture. The rule specifically monitors when this command is launched by non-standard parent processes like 'report.bin' or 'nw.exe', which may indicate malicious reconnaissance or network monitoring tools.

This rule detects file access, creation, modification, or renaming operations involving sensitive files associated with cryptocurrency wallets (Bitcoin, Electrum, ElectrumSV), game account configurations (Battle.net, Steam, Minecraft), and browser-based cookies (Roblox). The rule filters out legitimate process interactions, identifying suspicious activity from unknown or unauthorized applications potentially attempting to exfiltrate credentials or session tokens.
