PetFlow Data Breach

What happened

In December 2017, the pet care delivery service PetFlow suffered a data breach which consequently appeared for sale on a dark web marketplace. Almost 1M accounts were impacted and exposed email addresses and passwords stored as unsalted MD5 hashes.

Exposed data

Recommended actions

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