Wanelo Breach

In December 2018, Wanelo, a digital shopping platform, experienced a data breach affecting approximately 23 million user accounts. The compromised data included email addresses, passwords stored as either MD5 or bcrypt hashes, names, physical addresses, and IP addresses. The breach was discovered in April 2019 when the data was found for sale on dark web marketplaces.
The hacker known as "Gnosticplayers" claimed responsibility for this breach, along with attacks on 44 other firms. Gnosticplayers has been known to sell large quantities of stolen data on dark web marketplaces, contributing to a series of significant data breaches during that period.
