Security

Variant hunting is one of the highest-impact activities in modern security research. Rather than looking for single, isolated vulnerabilities, variant hunting focuses on identifying patterns of flaws and tracking down all other instances of that pattern across products, codebases, or architectures. If a traditional vulnerability report is a single missing brick, variant hunting is discovering that the entire wall was built using the wrong blueprint. 🔍 What Exactly Is Variant Hunting? Variant hunting is the practice of: ...

1. Core Security Foundations Treat all input as untrusted. Validate strictly (whitelists over blacklists), normalize before checks, and enforce types and sizes. Use framework security features instead of writing your own. Least privilege: minimize DB, filesystem, and network permissions. Secrets management: use environment variables or secret stores, never hardcode. Dependency hygiene: pin and audit dependencies with pip-audit or Safety. Secure HTTP headers: add HSTS, X-Frame-Options, CSP, and others. Logging & monitoring: log relevant events, but never credentials. Testing: integrate Bandit and Semgrep in CI. 2. Preventing SQL Injection (SQLi) Principle: Never build queries using string concatenation. ...
