The new landscape: building got easy, protecting didn't
With today's AI tools, a working app or website goes from idea to live in days, with no technical team. That's great — and it's exactly why there's an entire generation of applications online that never went through a security review. The code works, but nobody looked at where an attacker would get in.
And "my app is too small to be a target" protects no one: attackers use automated programs that sweep the internet all day looking for the easiest doors to open. It isn't personal — it's fastest-first.
The most common flaws
- Exposed passwords and keys: it's common for AI to leave access credentials written inside the app or website's own code — for anyone who knows where to look, it's the house key under the doormat
- One customer seeing another's data: with broken access control, just changing a number in the URL can open up someone else's data
- Hidden commands (injection): fields where users type can be used to slip hidden orders to the system
- Vulnerable third-party components: every app uses off-the-shelf parts; many have publicly known flaws and get pulled into the project without review
- Test settings in production: debug mode left on hands an attacker internal details and a path inside
- Unprotected uploads: a malicious file disguised as a photo or document becomes an entry point
What's at stake
An exploited breach isn't just a technical scare. An attacker can reach the accounts tied to the app — yours and your customers' — leak the personal and payment data you're obligated to protect, or hijack access to the system and demand payment to give it back.
How to protect yourself
1. Don't keep secrets in the code
Passwords, API keys and credentials belong in configuration vaults, never written into the code that ships to production.
2. Test access control
Ask: if I change the number in the URL, can I see another user's data? That simple check catches one of the most exploited flaws on the internet.
3. Update your components
Third-party parts with known flaws already have published fixes — the risk is staying on the old version.
4. Get an independent review
The person who built it isn't the best person to review it. An outside assessment — like the Asterolabs security check — runs the app through the most common and dangerous flaws and hands back a report in plain language: what's exposed, how severe each item is, and what to fix first.
Keep building with AI — without carrying the breach along
The answer isn't to abandon AI tools: it's to review what they produce before someone with bad intent reviews it for you. Every serious test is run with written authorization, in a controlled environment, without taking down the service or deleting data.
If you built an app or website and don't know whether it's secure, start with the Asterolabs initial check — you see what's exposed before you decide on anything.
