SUBJECT: THE MALVERTISING THREAT
While tracking via fingerprinting is a privacy violation, Malvertising is a direct structural threat. Modern ad-units serve as automated reconnaissance agents. They query your terminal's software version to identify "unlocked doors"—unpatched vulnerabilities that allow for Remote Code Execution (RCE) or Sandbox Escapes.
VISUALIZING THE PROBE: PERIMETER AUDITING
If the script detects an outdated kernel or an unpatched JavaScript engine, it triggers an exploit. This bypasses the browser's safety "sandbox," allowing the script to plant viruses, ransomware, or credential-stealers directly onto your hard drive. Most of these attacks happen in the milliseconds before you even see the ad appear.

THE SOLUTION: RASPBERRY PI AS A SENTRY
Trying to patch every vulnerability as it appears is a losing strategy. The true solution is to move the shield to the Network Layer. By deploying a Raspberry Pi Node as a network-wide DNS sinkhole (Pi-hole), you kill the connection to ad-delivery servers before the scripts can even touch your browser.
The Pi-hole intercepts the request for the weaponized ad-server and returns a "dead" address (0.0.0.0). Because the script is never downloaded, the vulnerability scan never occurs, and your "unlocked doors" remain invisible to the adversary. This hardware-level shield protects every device in your home instantly.
TECHNICAL NOTE: Full assembly schematics and hardening guides for the Raspberry Pi Defensive Node will be added as a technical appendix in a future archive update.
