Application Security

C/C++ security in automotive software-defined vehicles

MISRA C:2025 now spans roughly 225 guidelines and explicitly covers AI-generated code — but memory-safety bugs still drive roughly 70% of the vulnerabilities patched in major C/C++ codebases.

Running Capture the Flag exercises for internal security training

DEF CON CTF has run since 1996, yet most engineering orgs still train security awareness with slide decks instead of the format that actually built the industry.

Chaos engineering for security resilience testing

A one-hour Cloudflare R2 outage in March 2025 traced back to a mistyped deploy flag during credential rotation — exactly the failure a security chaos experiment is built to catch first.

Python code injection: eval, exec, and pickle explained

eval(), exec(), and pickle.load() can each hand an attacker a Python interpreter — CVE-2020-1747 shows how one unsafe deserialization call became a real RCE.

Code injection risks in GenAI-generated code

Nearly 40% of GitHub Copilot's suggested programs contain exploitable vulnerabilities, and 19.7% of AI-generated code samples reference packages that don't exist.

The code-to-cloud AppSec checklist: unifying code, dependency, container, and config security

Log4Shell and the XZ Utils backdoor both proved the same thing: a flaw in one layer is only as contained as your weakest disconnected tool.

Command injection in Python: subprocess, os.system, and safe-by-default patterns

os.system() and subprocess.run(shell=True) both hand a string straight to /bin/sh — one unescaped semicolon is enough to run arbitrary commands.

Common Configuration Scoring System (CCSS) explained

NIST published CCSS in December 2010 to score misconfigurations the way CVSS scores bugs — most cloud teams have never applied it.

Sigstore vs. Notary v2 vs. Docker Content Trust: signing containers in 2026

Docker retires Content Trust on December 8, 2026, while fewer than 0.05% of Hub pulls ever used it — here's how Sigstore and Notary v2 actually replaced it.
