This rule detects HTTP traffic where a response from a Google Cloud Storage bucket (storage.googleapis.com) initiates a redirect via meta-refresh or JavaScript to a Vercel-hosted domain. This pattern is indicative of phishing infrastructure, where attackers leverage legitimate, trusted storage platforms to redirect users to malicious landing pages.

Detects network traffic associated with the NPM Btree malware campaign, specifically identifying command-and-control (C2) polling activities directed toward blockchain RPC endpoints like Alchemy and Infura. The rules monitor for specific API keys, C2 smart contract addresses via 'eth_call' JSON-RPC requests, and overall traffic patterns to known malicious infrastructure.

Detects network traffic indicating the use of Slack APIs as a command and control (C2) channel or for exfiltration. The rules monitor for specific TLS SNI strings, hardcoded Slack bot tokens, and specific channel IDs associated with the 'indexed-btree' malware campaign, which utilizes Slack as a C2 platform.

Detects outbound HTTP POST requests to the Polygon blockchain using the 'eth_call' JSON-RPC method, specifically targeting a known smart contract address associated with EtherHiding-style C2 infrastructure. This behavior indicates an adversary utilizing decentralized blockchain storage or services as an unconventional command-and-control channel to resolve malicious configurations or payloads.

This rule detects outbound HTTP requests to the blogspot.com domain, which is often used by malware for command-and-control (C2) communication, staging, or as an initial check-in mechanism. Attackers frequently abuse legitimate blogging platforms to host malicious content and evade network-based detections that might otherwise flag unknown or suspicious domains.
