Script Integrity Monitoring for Third-Party JS and Frontend Supply-Chain Risks

Third-party scripts are one of the biggest blind spots in modern web security. Hackal monitors your site for unauthorized JavaScript, vulnerable libraries, and supply-chain manipulations — before attackers can weaponize them.


What Hackal watches

77% of Sites Contain JavaScript Libraries with Known Vulnerabilities

Why Script Integrity Monitoring Matters

Client-side attacks bypass your server-side defenses. If an attacker injects a malicious script into your checkout page, your backend never sees it, but your customers' credit cards do. An unauthorized script can steal customer data, inject phishing pages, or divert payments. With third-party code powering analytics, ads, and chat widgets, visibility is your best defense against silent supply-chain attacks. Script Integrity Monitoring also helps supports PCI DSS 4.0 compliance requirements around script authorization.

CSP-Based Script Monitoring

Hackal monitors Content Security Policy reports to detect when unexpected scripts attempt to execute on your pages. If something tries to run that shouldn't, you'll know.

Headless Browser Scanning for Runtime Scripts

We render your pages in a headless browser to capture every script that actually executes, including dynamically injected code that static analysis misses.

Detect Unauthorized or Vulnerable Scripts

Hackal flags scripts loading from unexpected origins, inline code changes, and known-vulnerable library versions, helping you catch Magecart-style injections and compromised dependencies before they steal customer data.

Supply-Chain Attack Prevention

Modern sites depend on dozens of third-party scripts, from analytics and chat widgets to payment processors. Third-party scripts are a rising attack vector and a single compromised dependency can expose your entire customer base. Hackal watches the supply chain so you don't have to.
