Detects the download and execution of the malicious v7.msi installer from the domain camorreado.click. This file acts as a loader for the EtherRAT Node.js RAT, often delivered in the context of fake IT support phishing campaigns. The rule monitors both network connection events to the malicious domain and process creation events involving msiexec.exe execution of the specific MSI payload.
Detects the installation or network activity associated with the malicious npm packages 'nodemon-sudo' (v3.1.16) and 'tslint-conf' (v7.2.1). These packages use typosquatting or brand impersonation (targeting 'nodemon' and 'pino') by leveraging forged maintainer and author metadata to trick developers into installing them.
Detects successful non-interactive sign-ins to Azure CLI using the Resource Owner Password Credentials (ROPC) flow where Conditional Access policies failed to enforce multi-factor authentication (MFA). This typically indicates misconfigured Conditional Access policies, such as exclusions for non-interactive authentication methods or service accounts, which could be exploited by adversaries to bypass MFA.
Detects when the Secure Boot Advanced Targeting (SBAT) registry policy on Windows systems is either missing or contains outdated revocation entries (lacking 'shim,4' and 'grub,5'). This indicates the boot chain may be using vulnerable bootloader components susceptible to known security bypasses, as the system is not properly enforcing updated revocation generation policies.
Detects the creation or modification of persistence mechanisms (Windows Registry Run/RunOnce keys, Cron jobs, Systemd services, and macOS LaunchAgents/LaunchDaemons) that specifically reference Java executables or .jar files. This pattern is consistent with cross-platform malware such as QuimaRAT attempting to maintain persistence.
Detects the Cursor IDE (Cursor.exe) or its child processes accessing sensitive SSH private key files or cloud provider authentication credentials. This behavior is indicative of a compromised IDE process, potentially leveraging malicious extensions or MCP (Model Context Protocol) servers to exfiltrate secrets from the local filesystem.
Detects termination of security services or tampering with real-time protection configurations shortly after the loading of the PoisonX (g11.sys) kernel driver. This activity is indicative of a Bring Your Own Vulnerable Driver (BYOVD) attack aimed at disabling endpoint defenses prior to the deployment of ransomware or other malicious payloads.
Detects attempts to grant world-writable (0666) permissions to the /dev/kvm device node using chmod or setfacl, or unauthorized (non-root) accounts interacting directly with the device. Such configuration changes are associated with the Januscape (CVE-2026-53359) vulnerability, which allows local users to exploit a shadow MMU use-after-free in the kernel to escalate privileges to root or escape into the host from a virtualized environment.
Detects node.exe processes fetching remote content from specific IPFS dead-drop domains where the executing process does not write a corresponding script file to disk. This behavior is indicative of a fileless execution pattern where a 'caller.js' script fetches a payload and executes it directly in memory using the JavaScript Function constructor, bypassing traditional on-disk detection mechanisms.
Detects the use of the 'reg.exe' utility to export or save sensitive Windows Registry hives (SAM, SECURITY, SYSTEM) within a short timeframe on a single host. This pattern of credential dumping from the Registry is characteristic of INCRansom activity and other credential harvesting techniques.
