According to an email sent to affected students and workers, the gang gained access to an employee’s Salesforce account on March 18th. To minimize the impact, the compromised account was immediately shut down.

“That evening, the unauthorized actor, claiming to be part of a group known for targeting the Salesforce accounts of hundreds of companies, contacted Infinite Campus, demanding payment in exchange for the destruction of the Salesforce data they claimed to possess. Infinite Campus has not, and will not, engage with the unauthorized actor,” the email stated.

Charlie Kratsch, Founder and CEO of Infinite Campus, told the media that the Infinite Campus Salesforce instance was accessed, which contained the names and contact information of school staff members.

ShinyHunters, on the other hand, claimed to have stolen Salesforce records containing personally identifiable information (PII) and other internal corporate data. Members of the gang gave Infinite Campus until March 25th to come up with the ransom demand.

“This is a final warning to reach out by March 25th, 2026, before we leak, along with several annoying (digital) problems that’ll come your way. Make the right decision, don’t be the next headline,” ShinyHunters warned.

According to Troy Hunt, a cybersecurity researcher from Australia and creator of the Have I Been Pwned database, the ransomware extortion group has published the data that it exfiltrated.
