In November 2025, Beckett Collectibles experienced a data breach accompanied by website content defacement. The stolen data was later advertised for sale on a prominent hacking forum, with portions subsequently released publicly. The publicly circulating data initially included more than 500k email addresses reportedly belonging to North American customers, before a larger corpus of over 1M addresses was published the following month. The impacted data included names, usernames, phone numbers and physical addresses.
