The time the bloody NSA sent me an email to audit my PHP code (and how it shaped my whole career)
How an early 2000s security slip-up and a surprise email from the NSA shaped my lifelong Zero Trust approach to engineering, from simple PHP scripts to complex AWS Cloud architectures.
To share a bit of code with the Community, the workflow was proper old-school:
- You coded away on your local Apache server.
- You ran a good old grep -r to make bloody sure you hadn’t left any passwords or creds hardcoded.
- You zipped up the folder.
- You uploaded the .zip to a dev forum to help out the crew (and score a few street cred points while you were at it).
That’s exactly what I did with a little PHP file manager I built. Simple stuff, just sharing the love.
Until one day . . . I check my inbox and find a formal email straight from the NSA (Fort Meade in the flesh).
Their automated scan had picked up my tool and flagged a critical Path Traversal vulnerability (the good old ../ that wasn’t properly sanitised). To them, it wasn’t just a Sunday project: it was a potential backdoor if someone deployed it on sensitive infrastructure.
My blood ran stone cold, Mate! 😅 Talk about a proper wake-up call. I spent a few very stressful hours ripping my code apart, sanitising every input, patching the hole, and re-uploading a clean .zip before I could even think about getting a beer or hitting the sack.
The statute of limitations has definitely passed (nearly 25 years on!), but that cold sweat became the absolute catalyst for my whole engineering mindset.
What that day drilled into me for life:
- Security by Design, no worries: No user input is ever innocent. Data validation and sanitization have to be baked in from day dot, not slapped on like a band-aid later.
- Zero Trust mindset: Never trust the execution environment, and never assume the user is gonna be“nice”. - Uncompromising standards: From a small PHP script in the 2000s to the complex AWS Cloud Architectures I design today, the level of rigour around attack surfaces stays 100% the same.
At 51, whenever I design a Cloud architecture today, that 25-year-old reflex is still hardwired in me. Only difference now? My architectures pass with flying colours on the first go, no frantic emails from Fort Meade required. 😉
Who else remembers the good old days of deploying via .zip and FTP? 🤠
