What it detects

This rule detects inbound web requests carrying the User-Agent string Hello-World/1.0, a hardcoded identifier used by a scraper botnet concentrated in Taiwan that issues evenly distributed GET floods across ports 80 through 85. Surfacing this fingerprint reveals automated reconnaissance and scraping activity that often precedes targeted follow-on abuse.
