Renata had been using the same personal Gmail account since college. It was her backup email for everything: her bank, her Amazon account, her work Microsoft 365 profile and even her health insurance portal. She never thought much about it. It was just "her old email."
One Tuesday afternoon, she got a text. Her bank was asking her to confirm a password reset she never requested. She ignored it, assuming it was spam. By Wednesday morning, her bank account showed two transfers she did not make. Someone had not hacked her bank.
They had gotten into her Gmail first, then used it to reset everything else. Renata's personal email was the master key. And someone had found a copy.
What Happened
Renata's personal email account had a weak password and no multi-factor authentication. Once someone gained access to it, they used the "Forgot Password" feature on her bank's website. The reset link went straight to her compromised inbox. No special skills required. One account unlocked several others.
Most online accounts, including work-related ones, use an email address for identity verification and password recovery. If someone controls your personal email, they can reset passwords for your bank, shopping accounts, healthcare portals and potentially your work systems. You may not notice until real damage is done.
