Edmodo

Edmodo operates as an education platform that provides online services for learning and classroom interaction. The company’s headquarters is situated in the United States of America. As a digital service, it is accessed through web browsers and mobile applications by individuals seeking to share resources and manage academic activities.

In April 2017, a security incident occurred when a hacker obtained millions of user account details from Edmodo’s systems. The compromised information included usernames, email addresses, and passwords that had been hashed using the bcrypt algorithm with unique salts. Reports indicated that the breach affected roughly seventy‑seven million accounts, with about half of those records containing email addresses. The stolen dataset was subsequently advertised for sale on a dark web marketplace at a price exceeding one thousand dollars. Independent verification of the breach’s validity was carried out by attempting to reuse exposed email addresses during new account registrations, which confirmed that the data corresponded to active user profiles.

Following the discovery, Edmodo publicly acknowledged the incident and launched an internal investigation to determine the scope and cause of the unauthorized access. The organization stated that protecting user privacy remained a top priority and that it would take steps to strengthen its security measures. No further details about ownership, parent companies, or subsidiary relationships were disclosed in the available sources.
