A Lesson in Security.

Why I Stopped Building "GrayHat" and "Audgen": A Lesson in Security, Risk, and Reality

Every builder has a graveyard — a folder full of projects that once felt like the future and now sit quietly as reminders of what went wrong. Two of my headstones read GrayHat and Audgen. Both taught me more than any of my successful projects ever did, mostly because they taught me the difference between what you can build and what you should build.

This is the honest story of both.

Chapter One: GrayHat

Back in July 2025, I launched a site called GrayHat. The idea was simple and, at the time, exciting to me: a single place packed with thousands of "techniques" — a huge library of hacking-related content. I wasn't thinking about consequences. I was thinking about traffic, rankings, and the thrill of watching something I made actually get noticed.

And for a while, that's exactly what happened. I spent about Five months grinding — writing, publishing, optimizing, refreshing analytics like it was a slot machine. Slowly, the visitors started trickling in. Then the rankings climbed. For a first real project, it felt like I had cracked something.

But here's what I didn't fully understand back then: when you publish that kind of content, you don't just get readers — you get actors. People weren't visiting my site to learn in the abstract. Some of them were using it as a direct manual. Small websites started getting attacked. Worse, a growing number of visitors were using the material to run BIN attacks (Bank Identification Number attacks) at scale — activity that quietly costs real banks, mostly foreign ones, real money.

I had told myself I was just "sharing knowledge." Reality had a different label for it.

Then one day the reckoning arrived in my inbox. I received an email from cirt@cirt.gov.bd — Bangladesh's Computer Incident Response Team. The message was direct: they had reviewed my website, they had seen what was on it, and I needed to either take the site down or remove the BIN-related content. If I didn't, they would be forced to pursue legal action.

There's a very specific feeling that hits when a government cybersecurity body emails you personally. It's not excitement. It's the sudden, cold understanding that the "game" was never a game.

I didn't negotiate. I didn't try to argue that it was "just educational." I took the entire website down.

That was the end of GrayHat — and, honestly, the beginning of me actually thinking about ethics in what I build.

Chapter Two: Audgen

After GrayHat, I wanted to build something cleaner — something useful. That became Audgen.

Audgen was a text-to-speech (TTS) voice generator. On the surface, it was a genuinely good product. Users could type text and get natural-sounding audio back. Behind the scenes, it pulled from established providers — OpenAI, ElevenLabs, Google's voices, and others — and stitched them together into one simple, free tool. People liked it, because "free" and "high quality" rarely show up in the same sentence.

Then I decided to monetize. I launched a paid tier: an Audgen API key priced at $15 per million credits, while I was paying roughly $10 a month to keep things running. On paper, the margins looked incredible.

But this is the part where I have to be honest about why the economics looked too good — because it's also the part that eventually killed the project.

Audgen's "API" wasn't really my own inference engine. It was a wrapper. When someone used an Audgen key, my code quietly relayed their request to the real providers, captured the output, and handed it back to the user. The reason my costs stayed near zero wasn't clever engineering — it was that I was leaning on free-trial access I wasn't supposed to have, sourced through Telegram communities and automated sign-up tricks. For about twelve months, it worked, and I told myself I'd built something smart.

I hadn't. I'd built something fragile that depended entirely on a loophole staying open.

And loopholes close. The methods got patched. Once the providers tightened their systems, the whole foundation of Audgen collapsed. Suddenly there were no free credits propping up the margins. To be clear, I didn't lose a fortune — it's more accurate to say the profit simply vanished. What had felt like a business was really just an arbitrage that only existed while nobody was looking.

Then the final, almost anticlimactic blow: I couldn't keep paying for the domain. It expired. It got taken away. And just like that, Audgen was gone too — not with a dramatic shutdown, but with a quiet unpaid invoice.

What These Two Failures Actually Taught Me

Looking back, GrayHat and Audgen weren't really two separate mistakes. They were the same mistake wearing two different costumes:

I optimized for what worked, not for what was right. GrayHat "worked" until it hurt real people and real institutions. Audgen "worked" until it depended on something it was never entitled to.

Shortcuts aren't a foundation. If your entire model only survives while a loophole stays open or while nobody notices, you don't have a product — you have a countdown timer.

Consequences are patient. The CIRT email didn't come on day one. The patched trials didn't happen in week one. Both projects felt successful right up until the moment they weren't.

"Educational" is not a magic shield. Framing something as knowledge-sharing doesn't change what people actually do with it, and it doesn't change your responsibility for putting it out there.

I'm not proud of how either project made its money or its traffic. But I'm genuinely glad they failed when they did, and not later when the stakes could have been far higher. GrayHat taught me that reach without responsibility is dangerous. Audgen taught me that a business built on borrowed access is really no business at all.

These days, when I start something new, I ask a question I never used to ask: "If this succeeds completely, who does it hurt — and can it survive in daylight?"

That single question is worth more than everything GrayHat and Audgen ever earned me.
