Dubsmash Data Breach

What happened

In December 2018, the video messaging service Dubsmash suffered a data breach. The incident exposed 162 million unique email addresses alongside usernames and PBKDF2 password hashes. In 2019, the data appeared listed for sale on a dark web marketplace (along with several other large breaches) and subsequently began circulating more broadly.

Exposed data

Recommended actions

• Change your Dubsmash 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 Dubsmash — attackers weaponise breach data quickly.
• Stay alert for smishing (SMS phishing) and SIM-swap attempts using your phone number.
• Check whether your email address appears in this breach on haveibeenpwned.com.
