Potential TerminalFix Cloudflare Lure in PowerShell

Identifies PowerShell script blocks that print a fake Cloudflare verification lure. TerminalFix pages instruct the victim to paste a command into Windows Terminal or PowerShell. The script presents messages such as "Cloudflare verification", "Cloudflare ID:", or "I am not a robot" while it stages a payload. Review the full script block for download, extraction, and follow-on execution.

Potential FileFix Command via Windows Explorer Address Bar

Identifies suspicious commands written to the Windows Explorer address bar history (TypedPaths). Adversaries socially engineer users to paste a command into the address bar of File Explorer or of a browser's file upload dialog, a pattern known as FileFix; the writing process is therefore explorer.exe or the browser hosting the dialog.

Detects PowerShell launched with an encoded command or a download cradle whose process ancestry includes a Node.js npm package execution (`npx-cli.js` with a scoped or versioned package). Malicious npm packages and supply-chain compromises commonly run this from install or postinstall scripts to fetch and execute a second stage.

Potential NetScaler Log Poisoning Command Injection Attempt

Detects shell syntax in NetScaler Pitboss records or in Citrix records that combine Pitboss, packet-engine, or core terminology with shell syntax. This may indicate that attacker-controlled data poisoned an appliance log consumed by a privileged script. The behavior includes CVE-2026-88771, but the detection is intended to identify similar NetScaler log-poisoning command-injection attempts without requiring a specific vulnerability, failure phrase, or command.

Privilege Escalation via Parallels Appliance Extract Argument Injection

Identifies the Parallels Desktop root dispatcher (prl_disp_service) spawning tar/bsdtar with more arguments than its fixed extract command uses. The dispatcher always runs a 5-token command (tar -xf <archive> -C <dir>), so any additional arguments indicate an attacker-controlled folder name injecting extra tar flags. On macOS these flags let tar read or write attacker-chosen paths or execute an external program as root, resulting in local privilege escalation (CVE-2026-90894, Parallels

Unusual File Creation via Web Server

This rule leverages the "new_terms" rule type to detect unusual file creations originating from web server processes on Linux systems. Attackers may exploit web servers to maintain persistence on a compromised system, often resulting in atypical file creations. As file creations from web server processes are common, the "new_terms" rule type approach helps to identify deviations from normal behavior.

VM extensions run with high privilege on the guest (SYSTEM on Windows, root on Linux) and are a common code-execution and persistence primitive. The extension instance name is attacker-controlled and the Azure activity log records only that name, not the publisher or type, so the control plane cannot reliably identify the extension family (for

Potential Destructive AWS CLI Command Executed by GenAI Agent

Identifies a cloud CLI command that destroys infrastructure or identities, such as terminating EC2 instances, removing S3 buckets, or deleting IAM users, when it is spawned by a GenAI coding agent directly or through the agent's shell wrapper. A compromised or prompt-injected agent can be steered into wiping the developer's environment and cloud account using the credentials it already holds, as seen in the malicious Amazon Q Developer for VS Code v1.84.0 release (AWS-2025-015).

Identifies execution of a third-party S3 or object-storage client (S3 Browser, s5cmd, s3cmd, MinIO mc, rclone, Cyberduck, s3fs, goofys, juicefs) launched by a script interpreter, a shell one-liner, or from a temporary or user-writable path. After stealing cloud credentials, adversaries switch from the AWS CLI to these clients to enumerate and drain buckets in bulk. Gating on a scripted context separates post-exploitation automation from interactive developer use.
