Detects attempts to delete Azure resource locks protecting Site Recovery or Backup services, followed by credential retrieval (ListKeys) within a one-hour window. This sequence pattern is a strong indicator of an adversary attempting to disable backup protection before potentially destroying data or exfiltrating keys.

This sequence pattern is a strong indicator of an adversary attempting to disable backup protection before potentially destroying data or exfiltrating keys.
This rule detects reconnaissance activity targeting Azure App Service instances, specifically looking for attempts to access web-shell-like files, WordPress administration paths, PHP-CGI endpoints, or LangFlow code validation paths. It identifies potential Storm-3168 actor infrastructure through known IOCs or through patterns of high-volume, path-diverse HTTP requests that deviate from typical noise, helping to distinguish targeted probing from common internet background scanning.
This rule detects the creation of specific system mutexes commonly used by malware for persistence or to avoid multiple infections (Mutual Exclusion). It monitors for both a specific hardcoded mutex and a pattern-based approach (15-20 alphanumeric characters) initiated by executables from common temporary or user-writable directories, which is a frequent indicator of malicious secondary payloads or droppers.
Detects a precursor pattern identified as JADEPUFFER, where a failed 'ListKeys' operation (indicating an attempt to discover or access keys for a non-existent storage account) is immediately followed by a burst of destructive delete operations on critical cloud resources (e.g., storage, databases, key vaults) by the same actor.

Detects a coordinated, rapid deletion of a Key Vault, Function App, and App Service plan within the same resource group and time window by the same caller. This pattern is indicative of targeted destructive activity, such as that seen in the JADEPUFFER campaign, while explicitly excluding scenarios where the entire resource group is deleted, which is typical of routine IaC teardowns.
