PetFlow Data Breach (2017)

If you are a customer of PetFlow, here’s what’s now in circulation.

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.
