Detects the loading of the somkernl.dll module by 360speedld.exe or SoftupNotify.exe, or the execution of these binaries. These files are associated with 360 Safe/360 Security software components, and this rule monitors for their specific activity patterns, which may be used to identify software presence or potential process hollowing/masquerading attempts involving these legitimate components.

Detects instances where a non-SYSTEM process attempts to open a handle to winlogon.exe. Since winlogon.exe typically runs as SYSTEM and manages user sessions, unauthorized access to its process handle is often a precursor to credential dumping or token manipulation attacks aimed at escalating privileges to SYSTEM.

Detects the installation or execution of known remote access tools (RMM) from suspicious parent processes (browsers, archives) or from user-writable directories (Temp, Downloads). This behavior is characteristic of initial access and staging activities performed by ransomware operators or Initial Access Brokers (IABs). The rule excludes known IT-managed deployment paths and signed binaries used by the organization.

Detects a process that has established a connection to the Telegram Bot API subsequently performing a large volume of file deletions across multiple folders within a 15-minute window. This behavior is indicative of a remote-controlled destructive attack, such as the deployment of a wiper malware (e.g., HEAVYGRAM or CHOSEN BRICK) triggered via Telegram C2 commands.

This rule detects modifications to the Windows Registry 'Run' keys that point to specific, potentially suspicious executable paths located in 'C:\ProgramData\'. These paths are commonly associated with persistence mechanisms used by malware or unauthorized software to ensure execution at system startup.

Detects the use of PowerShell, pwsh, or cmd to execute the 'Add-MpPreference' command with the '-ExclusionPath' parameter, specifically targeting common directories like Telegram Desktop or specific system directories. This activity suggests an attempt to bypass security scanning by excluding known malicious locations or folders from Microsoft Defender's real-time monitoring.

This rule monitors for execution of files with specific SHA256 hashes known to be malicious, and network connections to a known malicious domain associated with Vultr storage. It aggregates file creation, process execution, and network connection events to detect potential threat activity.

This rule detects file creation or modification events occurring within the 'ProgramData\ZlibDate' directory. This specific path and the associated file extensions (.Dat and .zip) are frequently associated with data staging activities or unauthorized file management by malicious software attempting to persist or exfiltrate data under the guise of legitimate application data.

This rule detects the creation of files in directory paths that look similar to the legitimate 'C:\Windows\SysWOW64' folder but contain a hidden trailing space (e.g., 'C:\Windows \SysWOW64'). Attackers use this directory spoofing technique to hide malicious files or executables from users and some security tools that might not normalize the path correctly.

This rule detects the execution of a process named 'WhatssApp.exe' from a non-standard location ('C:\ProgramData\Drivers\Whatsapp\'), which is indicative of masquerading. It further correlates this activity with the prior termination of the legitimate 'whatsapp.exe' process within a 30-minute window, a pattern often associated with 'WhatsappCheker' or similar malicious tools designed to hijack legitimate application sessions.

Detects instances where a process named MsCache.exe deletes files within the Google Chrome User Data directory. This pattern may indicate unauthorized activity by a process masquerading as a cache-related utility to modify or delete browser-related artifacts.

This rule detects potentially malicious activity by monitoring the execution of Python interpreters or specific suspicious executable names from within the C:\ProgramData directory. The detection logic focuses on processes launching from directories associated with configuration or data storage folders, often used by malware for staging or execution to avoid detection. It specifically flags Python execution involving certain suspicious file or argument strings, and the launch of named executables (e.g., RuntimeSSH.exe, smqdservice.exe) located in specific ProgramData subdirectories.
