Security News > 2021 > March > Cloudflare Page Shield: Early warning system for malicious scripts
Cloudflare has released a new feature that aims to protect websites from Magecart and other malicious JavaScript-based attacks.
A typical cyberattack is introducing malicious JavaScript onto a website to redirect visitors to malicious sites, display phishing forms, exploit vulnerabilities, and steal submitted payment information.
To introduce malicious scripts on a website, threat actors will commonly add the malicious inline JavaScript to the web page, add an external malicious JavaScript dependency file under their control, or compromise an existing third-party script in a supply-chain attack.
Today, Cloudflare announced a new security feature called Page Shield that will detect attacks in end-user browsers caused by malicious JavaScript dependencies.
With today's unveiling of Page Shield, Cloudflare is starting with a 'Script Monitor' tool that will report to Cloudflare every time a visitor on a protected site executes a JavaScript dependency file in their browser.
In the future, Cloudflare states that they plan on adding additional features that will issue alerts when the content of a script has changed of contains malicious signatures.
