RCE in React Apps: It's Not Where You Think
Browsers sandbox your React code, so RCE is impossible — right? Wrong. The remote code execution in modern React apps lives in places most developers never look: server actions, build pipelines, and the npm tree underneath your bundler.
Pen-Test Your Own Mail Server: A Mail-Layer Hardening Checklist
After you think your mail server is secure, attack it. Here's a 30-item checklist focused strictly on the mail layer — recon, TLS, relay tests, smuggling probes, and the credentials you'll never miss until you do.
Postfix and Dovecot Misconfigurations That Will Bite You in 2026
Most successful attacks against self-hosted mail aren't CVEs — they're config-file mistakes. Here are the eight misconfigurations that show up over and over, with the exact lines that fix each one.

25 Years of Email Server CVEs: Why the Same Bugs Keep Coming Back
Mail server vulnerabilities aren't a random walk. Look at twenty-five years of Postfix, Dovecot, Sendmail, and Exim CVEs and four bug classes account for almost everything. Here's why those classes keep recurring.
mbox vs Maildir vs Database: How Mail Actually Sits on Disk
Where your messages physically live shapes everything from backup strategy to incident response. Here's mbox at the byte level, Maildir's atomic delivery, and why the storage layer is where forensics actually happens.
