Everything you need to know to prevent supply chain JavaScript attacks

Supply chain JavaScript attacks are kind of like a thunderbolt. The boom starts in one place, then reverberates along a path, surprising people, shaking windows and, if there is a storm large enough to accompany the thunder, leaving varying degrees of devastation in its wake. Last week’s story of a multi-year campaign by threat actors to insert malicious JavaScript into vulnerable WordPress sites is a good reminder of the importance of client-side security and what companies need to do to prevent JavaScript supply chain attacks against their websites and web applications. .

Supply chain JavaScript attacks are on the rise. Are you ready?

Data-stealing malware

At the heart of the problem is the criminal’s desire to obtain sensitive data (credit card information, login credentials and personally identifiable information (PII)) or to install adware or another type of malware. Threat actors gain access to websites and web applications by exploiting existing vulnerabilities in JavaScript code or by creating malicious scripts designed to be injected directly into web applications. This data-stealing malware or adware can take the form of Magecart, JavaScript sniffers, cross-site scripting, formjacking, and a host of other types of client-side attacks.

JavaScript-Based Software Supply Chain Attacks

A software supply chain attack starts with software, in this case client-side JavaScript code. JavaScript was never designed with security in mind, which makes it extremely vulnerable to attack. JavaScript vulnerabilities can infiltrate websites and client-side applications in several ways:

  1. Developers with little or no security experience inadvertently insert faulty or fragmented code into a web application or website.
  2. Hackers manipulate the source code of existing web applications by injecting malicious scripts directly into the website.
  3. Faulty or intentionally malicious JavaScript finds its way into a web application through open source repositories and the software supply chain.

With so many websites and web applications assembled during the software development process by developers using third-party JavaScript from open-source and third-party JavaScript libraries, it is inevitable that applications will eventually come under attack. Any business using JavaScript code, add-ons, or plug-ins from third-party sources puts itself and its customers at risk.

Recent WordPress Attacks

In the case of the recent WordPress attacks, security researchers discovered that malicious code had been embedded in hundreds of websites that redirected users to the same pages, but instead contained phishing pages and malware, and sometimes unwanted advertising scams (like fake computer infection warnings). According to the researchers who uncovered the attacks, the hackers focused on injecting malicious scripts into WordPress themes and plugins containing known JavaScript security vulnerabilities.

The Growth of JavaScript Supply Chain Attacks

Software supply chain attacks are currently dominating the news headlines. In fact, recent studies suggest that supply chain attacks tripled in 2021 compared to 2020, and there’s no reason not to expect equal or greater growth in coming years. . According to a 2021 report published by ENISA, the European Union Agency for Cybersecurity, on the subject of the threat landscape for supply chain attacks, threat actors are focusing on both about existing code and about malware that can exploit that code. According to the report, around 66% of attacks focused on vendor code and 62% of attacks relied on malware to exploit that code. With approximately 98% of all web applications using JavaScript, businesses can expect the supply chain impact of JavaScript attacks to reverberate globally.

Automation and synthetic users can help prevent attacks

Advanced client-side security solutions, such as client-side attack surface monitoring solutions, use automation to protect websites and web applications. By deploying synthetic users during threat detection scans to act and interact like a real human would, these types of solutions autonomously simulate real user behavior to identify malicious scripts and unauthorized actions on web assets. , then categorize and report vulnerabilities and client-side security attacks. . Other client-side attack surface monitoring solutions use JavaScript security permissions to prevent data exfiltration by automatically applying security configurations and permissions for continuous protection against malicious client-side activity and third-party scripts .

Supply Chain JavaScript Attack Prevention Guide

Our new white paper (Guide to Preventing JavaScript Supply Chain Attacks) can give businesses a head start on the ins and outs of the types of threats and attacks affecting businesses today. The whitepaper provides readers with a guide to understanding the impact of vulnerable JavaScript on a supply chain tightly connected and integrated with modern websites and web applications. It explores the fundamental dangers associated with JavaScript-based client-side coding structures, including how the software development process can sometimes create broken and vulnerable code.

  • Understand client-side and server-side threats
  • Learn more about inherent JavaScript vulnerabilities
  • Explore the customer side and supply chain connection
  • Understand the different types of JavaScript exploits
  • Understand the impacts of attacks
  • Learn how to prevent attacks

It is no longer enough to simply secure the perimeter and the server side with tools such as web application firewalls. Organizations need to protect their front-end or “client-side” if they want to protect their JavaScript assets and keep end users safe.

I would like to invite you to download the white paper—Guide to Preventing JavaScript Supply Chain Attacks—to better understand the impacts of JavaScript attacks and the importance of client-side security.
