  • Record status: Developing record. Reviewed August 9, 2026; updated as evidence emerges.

What happened

Exploitation of a private beta application to view and download server files, including a Myspace93 password file. [1]

Impact

Myspace93 account records containing email and IP addresses, usernames, and passwords stored without encryption. [2]

Documented data types include:

  • Contact information — Email addresses listed by HIBP; the operator’s statement focuses on the password file rather than enumerating all record fields. [1][2]
  • IP addresses — IP addresses listed by HIBP. [1][2]
  • Usernames and account identifiers — Usernames listed by HIBP. [1][2]
  • Account credentials — Passwords stored without encryption according to the operator and described as plaintext by HIBP. [1][2]

A cited record reports 46,105 records (Unique email addresses in HIBP’s verified corpus; distinct from the operator’s approximate more-than-45,000-password-file statement and not a person count; as of 2026-05-21). [1][2]

Timeline

  1. Documented event

    Month-only January 2021 event represented by the first day because the schema stores dates; neither source establishes January 1 as the actual day.

Threat Group & Attack Vector

Windows93’s operator said trusted community members exploited a private beta application to display private server files and created a program to download the server. [1]

The operator said the Myspace93 credentials taken in January were leaked in June and were then used to access an administrator account and inject content. [1]

The operator removed the beta application, implemented a mandatory password change for pre-February 2021 accounts, shut down major social services temporarily, began notifying affected users, and started encrypting remaining account credentials. [1]

Actors

  • No threat actor group has been identified in the reviewed public evidence.

TTPs

  • No specific MITRE ATT&CK technique is currently mapped for this case.

Response

The operator said the downloaded material included Windows93 source files and an unencrypted file containing passwords for more than 45,000 Myspace93 users. HIBP marked the Windows93 incident record verified and not fabricated. No access path, attribution, scale, or recovery detail is inferred beyond the cited claims. [1][2]
