Most people picture a hacker sitting at a keyboard, targeting them specifically. The reality is more industrial — and in some ways more unsettling. Your data is a commodity. Here's what happens to it.
When your credentials or personal data appear in a breach, they don't go to one person who plans to personally ruin your life. They go into circulation — lists that are bought and sold on criminal marketplaces, often for less than a dollar per record. The buyer isn't interested in you. They're interested in volume.
The pipeline
Beyond credential stuffing, personal data enables targeted phishing — emails that reference your real name, your bank, a service you actually use. They're more convincing because they're built on real information. Breached data also feeds identity theft: opening credit accounts, filing fraudulent tax returns, renting property in your name.
What limits the damage
Two things break the pipeline at Step 3: unique passwords per account, and two-factor authentication. If your credentials appear in a breach but every account has a different password, the stuffing attempt returns nothing. If you also have 2FA, a correct password still isn't enough.
- Unique passwords per site eliminate credential stuffing across accounts
- A password manager makes this practical — you never type or remember the generated passwords
- A VPN prevents additional data capture on public networks where you might otherwise expose session credentials
- Check your email at haveibeenpwned.com to know which breaches you're already in
The scale of this is industrial. Billions of credentials are in circulation. The machinery to exploit them is automated and cheap. The defences — unique passwords, 2FA — are simple and available. The gap between being exposed in a breach and being actually compromised comes down mostly to whether the attacker finds something that still works when they try it.
Frequently asked questions
What is a data broker and why does it matter for identity theft?+
Data brokers legally aggregate and sell personal information — your name, address, phone, relatives, and more. This data is the raw material for social engineering attacks and targeted phishing, which are primary pathways to identity theft.
How do I remove myself from data broker databases?+
You can manually opt out of each broker individually, which takes many hours and requires re-submission as brokers re-add your data. Services like Incogni automate this process — sending removal requests to hundreds of brokers and monitoring for re-addition.
How common is identity theft in the US?+
Approximately 33% of US adults have experienced identity theft, per research from IPX1031 and Demandsage. The FTC received over 1.13 million identity theft reports in 2024. Losses totalled $12.7 billion that year, according to Experian.
