A list of alleged attendees from the Roblox Developers Conferences held between 2017 and 2020 was circulated on a forum in July 2023. The material contained 4,000 unique email addresses together with names, usernames, dates of birth, phone numbers, physical addresses, IP addresses and T-shirt sizes. The incident was reported on 18 December 2020.

What happened

The records were presented as attendee information from multiple Roblox developer events spanning 2017 to 2020. Public reporting states that the data set included 4,000 distinct email addresses along with the additional fields listed above. No further details on the original acquisition method, exact date of any intrusion, or total volume of files have been disclosed.

How a breach like this happens

Incidents involving conference or event registration data commonly begin with unauthorised access to an online registration platform, a third-party service provider, or an internal database that was not fully decommissioned after the event. Once obtained, the material can be copied and later shared on forums or other channels without the knowledge of the original organisation. Timing between the initial access and any public circulation can vary from months to years, and the precise vector is often not confirmed in public statements.

About Roblox Developer Conference (2023)

Roblox Developer Conference events bring together creators, programmers and partners who build experiences on the Roblox platform. Such gatherings collect registration details that routinely include contact information, account identifiers and limited personal descriptors such as clothing sizes for merchandise distribution. A compromise of these records is consequential because the affected individuals are often independent developers whose professional and personal contact data can remain relevant long after the event concludes.

What was likely exposed

The circulated list is reported to contain clothing sizes, dates of birth, email addresses, IP addresses, names, phone numbers, physical addresses and usernames. No confirmation has been issued on whether additional fields such as passwords, payment details or internal notes were also present. Exact contents beyond the fields already named remain unconfirmed.

The real-world impact

Individuals whose details appear in the material may receive unsolicited contact at the listed email addresses, phone numbers or physical addresses. Dates of birth and usernames can be used to link accounts across services, while IP addresses recorded at the time may assist in mapping prior online activity. For the organisation, the circulation of older event data underscores the long-term retention risks associated with registration records even after the events themselves have ended.

What to do if you're exposed

Review any email accounts associated with the listed addresses for unexpected login attempts and enable multi-factor authentication where available. Monitor phone and postal contact points for unusual messages. Individuals can run a free exposure scan of their email address against known breach data sets to determine whether their information appears in additional records.

Verified breach. Breach data provided in part by Have I Been Pwned, used under CC BY 4.0.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.

Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
