In October 2025, MyVidster, a video sharing/bookmarking platform, experienced a data breach. The data of almost 4 million users was posted to a public hacking forum. This incident was reported by Have I Been Pwned on October 27, 2025, and is separate from a 2015 breach involving the company.
The confirmed data types exposed in this breach include email addresses, usernames, and in a small number of cases, profile photos. The estimated number of affected individuals is 3.9 million users. Information regarding specific U.S. states affected, SSN, medical, or financial data involvement has not been disclosed.
Details can still emerge as investigations or disclosures continue, and official notices may be delayed.
