Facebook Data Leaks: Scraped Records, Exposed Databases and What to Do

Data leaks involving Facebook have a particular character. Many were not the result of hackers breaking into the company’s core systems. Instead, researchers found large collections of user information, such as profile IDs, names and phone numbers, sitting in unsecured databases or posted on hacker forums. Reports in late 2019 described a database with more than 267 million user IDs and phone numbers. Later reports described larger collections, including a 2021 data set with hundreds of millions of records posted for free. Whatever the exact count, the pattern teaches an important lesson: data that is public or loosely protected on a platform can be collected at scale, and once collected it travels. This guide explains how such leaks happen, why phone numbers are the crown jewel, what risks follow and how to protect yourself. For the platform’s wider practices, see what happens to your data on Facebook.

1. What was reported

In December 2019, a security researcher identified an online database containing more than 267 million Facebook user IDs, phone numbers and names. Security firm Comparitech reported that the database also appeared on a hacker forum as a downloadable file, that most affected users appeared to be in the United States and that the data was probably collected through illicit scraping or the abuse of an interface. The database was later taken down, but copies may have circulated. A subsequent report in March 2020 described a related set of roughly 300 million records. In 2021, a data set said to include about 533 million users’ details was posted publicly.

We summarize these as reported by researchers at the time. Numbers and details evolved, and the company has described the data sets as the result of scraping and has said that vulnerabilities were fixed. For current facts, rely on the latest official statements and reputable reporting.

2. How leaks like this happen

Scraping

Automated tools can collect public profile information at huge scale. If your profile shows your name, photo, city, workplace or friends list, a scraper can capture it. Combined with phone-number lookup features, scrapers can match numbers to profiles.

Interface abuse

Features that let people find others by phone number or email can be abused by sending large numbers of requests and recording the results. Companies change these features over time, but data collected earlier remains.

Unsecured databases

Sometimes the person or company that collected the data stores it carelessly, leaving it open to anyone with the address. Researchers find such databases regularly, and so do criminals.

Third-party apps

Apps with broad permissions can collect and expose data. See Facebook apps collect and sell personal information.

3. Why phone numbers matter

A phone number is now an identifier. It is used for account recovery, two-factor authentication, payments and contact tracing across services. A leaked number tied to a name allows:

Targeted phishing and text scams that mention your name or social profile.
SIM swap attempts, where a criminal convinces a carrier to move your number to their device in order to intercept codes.
Account recovery attacks on services that use the number.
Profile linking with people-search records, which then reveal addresses and relatives.
Harassment, including repeated calls and messages.

Our guide to how to remove your phone number from the internet covers the broker side, and removing old phone numbers helps with outdated listings.

4. Who is at risk

Anyone with a public profile, a phone number attached to an account or friends who were scraped is potentially included. People with public job information or large friend lists are easier to profile. People whose numbers appear in many places, such as business listings or contact forms, are especially exposed. If you are unsure, assume your profile data may be in circulation and act accordingly.

5. What to do now

Check for exposure

Use a breach notification service to check your email address and, where supported, your phone number. A hit shows that your information appears in a known data set. No hit does not prove safety.

Tighten Facebook settings

Limit who can find you by phone number or email, hide your friends list, restrict profile details to friends and turn off public search engine indexing where offered. See how to use Facebook privacy settings and managing privacy on Facebook.

Protect your phone number

Ask your carrier for a port-out PIN or number lock, use an authenticator app instead of text messages for two-factor authentication and avoid publishing your number.

Expect phishing and verify

Treat unexpected messages with suspicion. Do not click links or share codes. Report scams at reportfraud.ftc.gov.

Review account security

Use unique passwords and two-factor authentication. Check recent logins.

Remove public listings

A leaked phone number is more dangerous when matched to an address. Opt out of people-search sites using official pages such as Spokeo, the PeopleConnect suppression center and That’s Them. California residents can use DROP at privacy.ca.gov/drop; registered brokers began processing on August 1, 2026 and repeat every 45 days.

Consider a credit freeze

If other identifiers were exposed in other incidents, a freeze adds protection. See what is a credit freeze.

6. What the statistics suggest

The FBI’s Internet Crime Complaint Center received 67,456 personal data breach complaints in 2025, with reported losses of $1.31 billion, and 31,675 identity theft complaints with $185.8 million in reported losses (ic3.gov). The Federal Trade Commission received about 3 million fraud reports (ftc.gov). These numbers do not attribute any case to a Facebook data set, but they show the environment in which leaked phone numbers and names get used.

7. Lessons for every platform

The point is not unique to one company. Any platform with public profiles and a contact-lookup feature can be scraped. Practical lessons:

Share the minimum in public profiles.
Do not rely on obscurity: assume public means collectible.
Treat your phone number as sensitive and avoid using it as a public handle.
Prefer authenticator apps or passkeys to text-message codes.
Use different email addresses and aliases for different services.
Review contact-discovery settings on every platform you use.

See Google and Facebook as personal data hoarders for a broader perspective.

8. Timeline: responding to a platform leak

When	Action
Day 1	Check exposure, tighten settings, enable stronger authentication
Day 2	Add a port-out PIN, review recent logins
Week 1	Remove broker listings, watch for phishing
Month 1	Re-check listings, review credit reports
Ongoing	Treat unexpected messages with skepticism

9. What a leaked profile record is actually used for

A scraped profile record is rarely used on its own. Criminals join it with other leaked data: a phone number from one dump, a home address from a people-search listing, a password from an older breach. The joined profile makes impersonation calls, SIM-swap attempts and tailored phishing far more believable. That is why the phone number and email address in a leak matter more than the name. They are the keys that unlock account recovery flows.

The practical response is layered. Turn on app-based two-factor authentication rather than text-message codes. Use unique passwords in a manager. Place a free credit freeze, and report any misuse at IdentityTheft.gov. Then shrink the other half of the profile by removing the address and relatives listings that brokers publish, which our data removal guide walks through step by step. A leak you cannot undo; the data brokers’ copy of you, you can.

10. How to tell if a leak affects you today

Search your email address and phone number in a reputable breach-notification service, then check the platform’s own account-security page for alerts. If you see a match, change that password, review logged-in devices and revoke unknown app permissions. Treat any unexpected call or message that quotes your personal details as hostile until you verify it through an official number you look up yourself.

11. Three scenarios and what to do

Scenario 1: You receive a text that mentions your name and profile. Do not click. Delete and report. Your data may be in a leaked set.

Scenario 2: You find your number on a people-search page. Opt out and check for other numbers listed.

Scenario 3: Your phone suddenly loses service. Contact your carrier immediately in case of a SIM swap, and secure email and financial accounts.
