pwn.college is a free, hands-on education platform for learning core cybersecurity and hacking skills, maintained by a team at Arizona State University. Learners progress through belt ranks, starting with a 'white belt' and earning belts through practice. Hackers continue beyond the platform to 'brown belt' and eventually 'black belt' status, which must happen outside the dojo. The site powers much of ASU's cybersecurity curriculum and asks users not to post writeups or walkthrough videos of challenge solutions. It points learners toward CTFtime.org for Capture The Flag events and a GitHub list of wargames for further practice. The underlying infrastructure is open source and accepts pull requests, though some modules remain closed-source.

Một lỗ h bảo mật nghiêm trọng đã được phát hiện trong phiên bản 4.6.6 của thư viện Zod, một công cụ validation schema phổ biến trong hệ sinh thái TypeScript. Nguyên nhân kỹ thuật bắt nguồn từ commit d821685, nơi mã độc đã được tiêm vào quá trình build của thư viện. Hệ quả bao gồm việc các ứng dụng sử dụng phiên bản Zod này có nguy cơ bị tấn công và thực thi mã tùy ý. Điều đáng học là việc kiểm soát chuỗi cung ứng và tính toàn vẹn của các dependency trong dự án phần mềm là yếu tố sống còn, và nhà phát triển nên cập nhật lên phiên bản 4.6.7 ngay lập tức để vá lỗ hổng này.
Lập trình viên nên đọc bài này để cập nhật lỗ bảo mật Zod 4.6.6 và ngăn chặn mã độc ảnh hưởng đến dự án của mình.
