Windows93 / Myspace93 Data Breach (2021): What Was Exposed & What To Do
The Windows93 / Myspace93 Data Breach (2021) (reported January 1, 2021) exposed Email addresses, IP addresses, Passwords and Usernames belonging to roughly 46K people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
The Windows93 site reported the incident on 1 January 2021. The breach was limited to the Myspace93 subsection and involved the compromise of 46,000 accounts. Attackers obtained server files through exploitation of a beta application. The resulting data set, which contained email addresses, IP addresses, usernames, and plain-text passwords, appeared on public leak sites several months later in June 2021.
How a breach like this happens
Incidents of this type often begin with the discovery of an exposed or insufficiently protected application component, such as a beta feature that retains elevated access to backend systems. Once initial access is obtained, an attacker can retrieve files directly from the server rather than through normal user channels. When credentials are stored in plain text, any files that contain account databases immediately yield usable login information without additional processing.
About Windows93 / Myspace93
Windows93 is a web-based parody project that recreates the appearance and interaction style of older operating systems and social platforms, including a subsection styled after early Myspace. Sites of this kind maintain user accounts to support features such as profile creation, messaging, and content sharing. The data they collect typically includes the identifiers and contact details required for account management and basic site functionality.
What was likely exposed
The records released after the incident list four categories of information: email addresses, IP addresses, usernames, and passwords stored in plain text. No other data types are named in the available reporting. Because the exact contents of the server files have not been independently verified beyond these fields, the full scope of any additional information that may have been present remains unconfirmed.
What's at stake
Plain-text passwords allow anyone who obtains the data set to attempt direct access to the affected accounts and to any other services where users reused the same credentials. Email addresses and IP addresses can be used for targeted follow-on contact or correlation with other data sets. For the organisation, the exposure highlights the consequences of storing authentication data without hashing and of leaving administrative functions accessible through development features.
What to do if you're exposed
Change the password for the affected account and for any other service that used the same password. Enable two-factor authentication where available. Review recent account activity for signs of unauthorised access. Readers can run a free exposure scan of their email address against known breach data to determine whether their information appears in this or other publicly documented incidents.

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.
