In November 2024, the South Korean education platform PoinCampus suffered a data breach which was later published to a popular hacking forum. The data included 89k unique email addresses, names and a small number of phone numbers and dates of birth. The data was provided to HIBP by a source who requested it be attributed to "Threat Actor 888".
