Detects execution of Coder-related processes or scripts where sensitive configuration parameters, such as database credentials or authentication tokens, are passed via command-line arguments. This behavior can lead to the exposure of credentials to other users or processes on the system through process listing.
This rule detects potentially unauthorized access to cloud resources or OAuth applications by identifying sign-ins or API calls originating from IP addresses or locations not previously observed for the user in the 30 days prior to a documented Coder registry compromise exposure window.
Detects network activity from infrastructure provisioner tools (Terraform, Coder) or shell processes attempting to connect to suspicious domains (e.g., coder-infra.com) that resemble legitimate infrastructure domains. This activity is indicative of credential theft, specifically targeting OIDC tokens, SSH keys, or authentication tokens during automated provisioning processes.
Detects anomalous actions within the Coder registry, such as template creation, version updates, or dry-run/workspace builds with module caching disabled, that occurred during a known registry compromise window on August 31, 2026.
Detects non-interactive sign-in events involving OIDC or external authentication tokens shortly after a known Coder registry compromise. The rule flags high-risk or at-risk single-factor authentication sessions, which may indicate the replay of stolen tokens harvested during the compromise window.
Detects processes that access sensitive browser credential or cookie files (e.g., Login Data, Cookies) followed by network activity within a 10-minute window, which is a common behavior pattern of information-stealing malware such as Amatera or ACR Stealer.
Detects modifications or creation of InprocServer32 COM registry keys by suspicious processes like mshta.exe or powershell.exe, which is indicative of COM Hijacking for persistence or privilege escalation.
Detects the creation of a scheduled task using 'schtasks.exe' where the initiating process is a script interpreter such as 'mshta.exe' or 'powershell.exe'. This behavior is often associated with the execution of malicious payloads or the establishment of persistence.
Detects the creation of a scheduled task using 'schtasks.exe' where the initiating process is a script interpreter such as 'mshta.exe' or 'powershell.exe'. This behavior is often associated with the execution of malicious payloads or the establishment of persistence.
This rule detects the use of 'mshta.exe' to execute a file from a remote location by inspecting the command line for 'http' protocols and a specific suspicious domain. Adversaries often abuse mshta.exe to proxy the execution of malicious HTML Application (HTA) files or scripts to bypass security controls.
