You built a great store. Your customers love the checkout. But a silent killer hides in your login form.
You forgot rate limiting.
Rate limiting stops users from making too many requests. Without it, attackers guess thousands of passwords per second. Your server lets them in.
This leads to disaster:
- Stolen credit cards.
- Leaked shipping addresses.
- High chargeback fees.
I tested a fashion site last month. It had zero limits. I wrote a short script. I cracked three accounts in eight minutes. The passwords were weak. All had saved payment methods.
Test your site now:
- Open an incognito window.
- Enter a valid email.
- Enter a wrong password 20 times fast.
If the site does not stop you, you are vulnerable.
Fix it with these steps:
- Block an IP after 10 failed attempts.
- Lock an account after 5 failures.
- Add delays between attempts.
- Use an invisible CAPTCHA.
Your team might say this is low priority. Tell them this:
One account takeover costs 250 dollars in fraud plus 50 dollars in fees. A developer fixes this in four hours. The cost of a breach is far higher.
