Jefit Data Breach

What happened

In August 2020, the workout tracking app Jefit suffered a data breach. The data was subsequently sold within the hacking community and included over 9 million email and IP addresses, usernames and passwords stored as either vBulletin or argon2 hashes. Several million cracked passwords later appeared in broad circulation.

Exposed data

Recommended actions

• Change your Jefit 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 Jefit — attackers weaponise breach data quickly.
• Check whether your email address appears in this breach on haveibeenpwned.com.
