17 Data Breach

What happened

In April 2016, customer data obtained from the streaming app known as "17" appeared listed for sale on a Tor hidden service marketplace. The data contained over 4 million unique email addresses along with IP addresses, usernames and passwords stored as unsalted MD5 hashes.

Exposed data

Recommended actions

• Change your 17 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 17 — attackers weaponise breach data quickly.
• Check whether your email address appears in this breach on haveibeenpwned.com.
