From a school system email:
PowerSchool has informed us that they have taken action with the hackers to ensure the unauthorized data was deleted without any further replication or dissemination. They do not anticipate any of the data being shared or made public and are working with cybersecurity experts and law enforcement to ensure ongoing data safety. PowerSchool indicated they will be providing credit monitoring to affected adults and identity protection services to affected minors in accordance with regulatory obligations.
But that is hardly a step toward assuring anything was deleted. Do the criminals really have a reputation at stake for keeping their word? Wouldn't that require we can confirm their identity?
In the FAQ, PowerSchool confirmed that the security incident was not ransomware in nature, but noted that it worked with CyberSteward, a Canadian organization that offers cyber-extortion incident response services, to negotiate with the threat actors responsible for the breach.
This confirms previous reporting that PowerSchool was the target of an extortion-only attack and that it paid a financial sum to prevent the hackers from publishing the stolen data.
