What hackers actually do with your data

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

WHAT HAPPENS TO BREACHED DATA
Step 1 — Breach occurs
Database of emails, passwords, personal info leaked
Step 2 — Data sold
Listed on criminal markets. Bulk purchase. <$1 per record.
Step 3 — Credential stuffing
Automated tools try email+password against banking, email, streaming, shopping
Step 4 — Working accounts sold again
Verified logins to Netflix, bank, email fetch a premium. Resold individually.
Unique passwords stop it here
If every account has a different password, Step 3 returns nothing usable

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.

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.
