Welcome back, my favorite little chaos agents. You’ve made it through login bypasses, token leaks, and IP spoofing. Now we reach the endgame: Account Takeover (ATO) . This isn’t just about getting into one account. It’s about orchestrating a symphony of vulnerabilities that let you become any user — or even take over entire organizations.
Account takeovers come in three main flavors:
- Targeted — You attack a specific user (phishing, XSS, etc.)
- Mass — You find a vulnerability that lets you change anyone’s email or password
- Organizational — You hijack an entire company’s workspace (think Slack, GitHub, or HR platforms)
Today, we’re covering the mass and organizational methods — because why steal one account when you can steal all of them?
