JavaScript is a scripting language used in web pages and applications, where flaws in code or dependencies can enable attacks and data theft.

Background for this topic.
JavaScript is a programming language used to add behavior to web pages and to build applications that run outside the browser, including server-side services and tooling. In browsers, scripts can read and modify a page’s content and interact with available web APIs, subject to the browser’s security boundaries.
Its main security risks include cross-site scripting (XSS), in which attacker-controlled input is executed as page code, and DOM-based flaws caused by unsafe handling of data in client-side code. Third-party scripts and package dependencies also expand the code supply chain and may expose user data or introduce vulnerable behavior. Practical controls include context-aware output encoding, avoiding unsafe DOM sinks, restrictive Content-Security-Policy rules, and reviewing, pinning, and monitoring dependencies for vulnerabilities.
A critical security vulnerability has been disclosed in a Python-based sandbox called Terrarium that could result in arbitrary code execution
Lightweight LLM-Driven Process Alerted Elastic's Security Team, Says James SpiteriElastic Security Labs quickly spotted the unfolding supply-chain attack that backdoored the popular JavaScript library Axios, thanks to a lightweight, AI-driven tool a researcher created to assess if repository changes looked malicious. Elastic's James Spiteri says further use cases abound.
Formbook attacks use combination of DLL Side-Loading and Obfuscated JavaScript to stay hidden, researchers at WatchGuard have uncovered
Two weeks ago, a suspected North Korean threat actor slipped malicious code into a package within Axios, a widely used JavaScript library. The immediate concern was the blast radius: roughly 100 million weekly downloads spanning enterprises, startups, and government systems. But beyond the sheer scale, the attack’s speed was just as worrisome – a stark […] The post Why the Axios attack proves AI is mandatory for supply chain security appeared first on CyberScoop.
