In March 2021, the mobile parking app service ParkMobile suffered a data breach which exposed 21 million customers' personal data. The impacted data included email addresses, names, phone numbers, vehicle licence plates and passwords stored as bcrypt hashes. The following month, the data appeared on a public hacking forum where it was extensively redistributed.

In May 2017, the education platform Edmodo was hacked resulting in the exposure of 77 million records comprised of over 43 million unique customer email addresses. The data was consequently published to a popular hacking forum and made freely available. The records in the breach included usernames, email addresses and bcrypt hashes of passwords.

In approximately January 2013, the Pokémon forum PokeCommunity suffered a data breach that impacted 330k users. The attack led to the exposure of data including Usernames, Email addresses, IP Addresses and Passwords stored as vBulletin hashes.

In mid-2019, news broke of an alleged LiveJournal data breach. This followed multiple reports of credential abuse against Dreamwidth beginning in 2018, a fork of LiveJournal with a significant crossover in user base. The breach allegedly dates back to 2017 and contains 26M unique usernames and email addresses (both of which have been confirmed to exist on LiveJournal) alongside plain text passwords. An archive of the data was subsequently shared on a popular hacking forum in May 2020 and redistributed broadly.
