Detects GitHub OAuth authorization, repository cloning, or ZIP downloads from source IP addresses that have not been observed for the specific actor within the past 30 days. This rule helps identify potential account compromise or token theft where an attacker attempts to access repository data from a new location, while specifically excluding bot/service accounts known for rotating CI infrastructure IPs.

005
Detects an Azure AD/Entra ID device registration or join event occurring within 60 minutes of an account-recovery action (password reset, MFA reset, or account unlock) for the same user identity. This sequence is indicative of an attacker registering a managed device to maintain persistent, long-term access following a successful account takeover or vishing-based helpdesk credential reset.

001
Detects a potential OAuth device code phishing abuse pattern where an authenticated device code sign-in is immediately followed by a new device registration or Primary Refresh Token (PRT) issuance for the same user, potentially originating from a different device or IP address.

001
Detects a single developer identity performing a high volume of git push or clone operations across a large number of distinct repositories within a short timeframe. This behavior is indicative of a compromised developer account being used to programmatically inject code into multiple repositories, potentially for a supply chain attack or mass payload propagation.

101
Detects an identity that performs a 'ListSecrets' operation followed by a high volume of 'GetSecretValue' or 'BatchGetSecretValue' requests within a short timeframe (15 minutes). This behavioral pattern is indicative of automated bulk exfiltration of secrets from AWS Secrets Manager, a common activity following an initial cloud environment compromise.

101
Detects rapid, large-scale deletion of Azure storage accounts by a single identity within a short timeframe. This behavior is indicative of destructive activity, such as a malicious actor attempting to disrupt service availability or impact organizational data, rather than typical administrative teardown.

Detects a suspicious sequence of behavior where an Azure service principal authenticates and immediately performs broad reconnaissance (enumeration) across multiple subscriptions and resource types. This pattern is often indicative of an adversary using a compromised service principal credential to map out an environment.

Detects a service principal attempting to delete multiple Azure SQL databases in a short timeframe, resulting in failures. This pattern is characteristic of malicious data destruction activity, such as that observed in Storm-3168 (JADEPUFFER) campaigns, but accounts for the possibility of misconfigured infrastructure-as-code pipelines by requiring a high volume of failed requests across distinct resources.

Detects a service principal or user account performing a burst of 'ListKeys' operations across multiple Azure Storage accounts. This behavior is indicative of an attacker attempting to dump access keys for multiple storage accounts after initial compromise or privilege escalation to gain further access to sensitive cloud data.

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.

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.
