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.
'Marstech1' Malware Targets Developers Through GitHub RespositoryNew North Korean malware is targeting cryptowallets with an unconventional command-and-control infrastructure and through malware embedded into a GitHub repository that's apparently the account of a Pyongyang hacker. The implant appears to have emerged late last December.
