Gab Data Breach

What happened

In February 2021, the alt-tech social network service Gab suffered a data breach. The incident exposed almost 70GB of data including 4M user accounts, a small number of private chat logs and a list of public groups and public posts made to the service. Only a small number of accounts included email addresses and / or passwords stored as bcrypt hashes with a total of 66.5k unique email addresses being exposed across the corpus of data.

Exposed data

Recommended actions

• Change your Gab password immediately, and update it anywhere you reused the same password.
• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing Gab — attackers weaponise breach data quickly.
• Check whether your email address appears in this breach on haveibeenpwned.com.
