Infinite Campus data breach: 137K accounts exposed
Severity: medium · Patch status: no-fix-needed · Since 2026-06-15
In March 2026, the student information system Infinite Campus was targeted in a ShinyHunters "pay or leak" extortion campaign. The group subsequently published data they alleged was taken from Infinite Campus, containing 137k unique email addresses along with names, phone numbers, physical addresses and support tickets. Infinite Campus subsequently sent notifications, advising that the exposed data largely consisted of "names and contact information for school staff" and that "the majority is directory information commonly found on school websites". Exposed data: email addresses, employers, job titles, names, phone numbers, physical addresses, support tickets, usernames. The breach dates from Mar 18, 2026; Have I Been Pwned loaded it on Jun 15, 2026.
What to do
- If you had a Infinite Campus account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
