What It Is

lzeroyuee.cn is lzeroyuee’s personal technical blog, with content mainly focused on cybersecurity, binary exploitation, CTF Pwn, Windows attack and defense, and malware analysis. The site displays the author’s profile information: a cybersecurity practitioner and malware analyst in the APT field, along with links to GitHub, email, and a donation page. It is not a commercial security platform, but rather a public site for personal knowledge accumulation and technical notes.

Core Features

The blog provides basic navigation such as article lists, archives, categories, tags, and an About page. The crawled content includes multiple low-level security topics, such as Protected Process Light, ret2dl-resolve, stack pivoting, SROP, Blind ROP, CreateDump, stack overflow, format string vulnerabilities, and integer overflow. These topics are useful references for learners of CTF Pwn, exploit development, and reverse engineering, with a clear focus on practical techniques and conceptual explanations.

Pricing

Articles on the site are free to read, with no membership, paid courses, or subscription wall found. The page includes a “buy me a coffee” donation option supporting Alipay and WeChat, which is a voluntary sponsorship model.

Pros and Cons

The main advantages are its focused content, Chinese-language explanations, and relatively technical subject matter, making it useful for Chinese-speaking security learners who want to quickly look up specific concepts. The exploit techniques covered are fairly typical and can serve as supplementary material for CTF or binary security study. The drawbacks are also clear: this is a personal blog, so update frequency, content completeness, and long-term availability are not guaranteed; the posts are more like topic-specific notes than a structured course, making them less beginner-friendly; and the crawled pages do not show community interaction features such as comments, search, or subscriptions.

Who It’s For

It is suitable for users who already have a foundation in Linux/Windows, assembly, ELF/PE, exploit development, or introductory CTF experience. Security professionals may also use it as a Chinese-language reference for specific technical points. Complete beginners are advised to first study more systematic resources such as CTF Wiki, Pwn Wiki, and 看雪论坛.

Access from China

The domain uses .cn and the content is a Chinese personal blog. The crawled information does not indicate access restrictions or reliance on overseas services, so based on current information, it should be directly accessible from mainland China. However, as a personal site, its stability depends on the server and ongoing maintenance.
