Understanding the anatomy of an account takeover
Ever wonder how someone just "poof" disappears from their own bank account while the balance hits zero? It's not magic, it is account takeover (ato), and honestly, it's one of the most annoying identity crimes we deal with in the sso space today.
Basically, ato is when a bad actor gets their hands on your login info and just. moves in. They don't just steal the password; they take over the whole identity. According to Feedzai (2025), this mess cost US adults about $15.6 billion in 2024 alone.
