A Nigerian startup launched their app. Built a clean OTP flow. No rate limiting on the SMS endpoint. Shipped it. Within 48 hours, their Termii balance went from ₦150,000 to zero. They woke up to failed OTP delivery complaints from real users. Checked their logs. Someone had been hitting their /send-otp endpoint in a loop with thousands of requests sending SMS to sequential phone numbers that were not even their users. This is called SMS pumping fraud. Here is how it works: • Fraudsters find your open OTP endpoint • They send requests to thousands of phone numbers, sometimes numbers they control on premium routes • Every successful SMS costs you money • They get a cut from the carrier. You get the bill. It is automated. It runs while you sleep. The fixes that would have stopped it entirely: • Rate limit by IP: max 3 OTP requests per IP per hour • Rate limit by phone number: max 3 requests per number per 10 minutes • Add a minimum delay between requests • Implement CAPTCHA or device fingerprinting on the frontend • Alert yourself when SMS spend spikes above a threshold None of this is complicated. All of it takes less than a day to implement. That startup lost ₦150,000 in two days and had to shut down OTP entirely while they fixed it. Their users thought the app was broken. Some never came back. The breach was not dramatic. No hacker. No sophisticated attack. Just an open endpoint and a bot. Secure your OTP flow before you launch. Not after you've learned the hard way.

HOW AFRICAN GOVERNMENTS HUSTLE FOR FUNDS 😂😂😂😂😂



@mrkay996 I told you he'd do it.

I had folks on my timeline justifying that Iran should be leveled because they “killed 30,000 of their citizens”. Meanwhile, the US/Israel armed them all along and started the protests. Most of them have seen these tweets and they have seen what the US has done since this War started but they are yet to admit they were wrong.

Trump praised Allah? 😱

Found her and I have sent her my support of 1million Naira.

Since we must blame Bola Tinubu for everything including hike in cement prices. How many houses did your father built when cement was sold at N38?
