Quidd

Quidd, also known as Quidd Marketplace and Quidd Collectibles, is headquartered in the United States of America. The company operates an online collectibles marketplace that facilitates the trading of digital collectibles among its users. This platform serves a global audience interested in licensed pop‑culture items and related virtual goods.

In December 2019, Quidd suffered a security breach that exposed account information for approximately four million users. The compromised data consisted of usernames, email addresses, and passwords that had been protected using the bcrypt hashing algorithm. After the breach, the stolen dataset was privately traded among various hacking groups before eventually surfacing on public forums. Investigations attributed the incident to a threat actor identified as ProTag, who initially offered the stolen data for sale on underground markets. Because bcrypt provides strong resistance to brute‑force attacks, decrypting the passwords was considered highly difficult for the attackers. The robust protection likely reduced the data’s resale value, which in turn contributed to its later release onto public forums. At the time of the breach’s public reporting, Quidd had not issued an official acknowledgment of the incident.

The use of bcrypt for password storage represents a notable security competency within Quidd’s technical infrastructure. No further details about the company’s ownership, parent‑subsidiary relationships, or additional regulatory roles are explicitly documented in the available sources.
