How we got abused via OTP
Going through my emails, I saw several about Twilio's auto-recharge, and then something about a suspension. We were using Twilio to send SMS messages and phone call alerts. "That's odd, let me check!". I logged into Twilio from my phone and checked. Horror. Instant horror. The balance was insane. But negative. I told my friend I need to sit down and check something. Pulled out my laptop and logged in. Same information. Same insane balance. Right there and then I knew it... we've been abused.
