🚨 Threat Advisory: Micro-task click farms and distributed headless Chrome instances charge as little as $15 to execute 5,000 fraudulent clicks against targeted publisher sites, triggering automated Google AdSense bans within 72 hours.

The Anatomy of a Competitor Click Bot Attack

Unlike human visitors who scroll naturally, read paragraphs, and occasionally click an ad relevant to their intent, click bots exhibit distinct mechanical signatures:

Mechanical Bot Signatures

  • Zero mouse curvature (linear cursor trajectories)
  • Instant click execution upon DOM render (under 1.2s)
  • Repeated ad clicks with 0-second dwell time
  • Missing `navigator.webdriver = false` declarations

Organic Human Signatures

  • Natural bezier curve mouse movements
  • Average page dwell time between 45s and 180s
  • Organic reading pauses and paragraph scrolling
  • Subtle window focus and blur transitions

How AdShield Pro Traps and Quarantines Attackers

AdShield Pro utilizes advanced heuristic telemetry embedded directly into your WordPress pages via `tracker.js`. The moment an IP generates more than the permitted click threshold (e.g., 3 clicks in 3 hours):

  1. The visitor's IP is immediately registered in the SQLite local quarantine ledger.
  2. All Google AdSense ad slots are cleared via DOM manipulation, serving zero ad requests to Google.
  3. The attacker continues to see the site normally, completely unaware that their attack script is no longer generating ad impressions.
