PowerSchool’s filings with state attorneys common and communications from breached faculties, nevertheless, recommend that thousands and thousands of individuals seemingly had private data stolen within the information breach. 

In a submitting with the Texas lawyer common, PowerSchool confirmed that just about 800,000 state residents had information stolen.

PowerSchool hasn’t mentioned what sorts of information had been stolen 

Not solely can we not understand how many individuals had been affected, however we additionally don’t understand how a lot or what sorts of information had been accessed throughout the breach.

The corporate’s incident web page additionally states that stolen information might have included Social Safety numbers and medical information, however says that “on account of variations in buyer necessities, the knowledge exfiltrated for any given particular person diversified throughout our buyer base.”

The hacker behind the info breach is just not but recognized

One of many greatest unknowns in regards to the PowerSchool cyberattack is who was accountable. The corporate has been in communication with the hacker however has refused to disclose their id, if recognized. CyberSteward, the Canadian incident response group that PowerSchool labored with to barter, didn’t reply to TechCrunch’s questions.

CrowdStrike’s forensic report leaves questions unanswered

One new element within the CrowdStrike report is {that a} hacker had entry to PowerSchool’s community between August 16, 2024, and September 17, 2024. 

The entry was gained utilizing the identical compromised credentials utilized in December’s breach, and the hacker accessed PowerSchool’s PowerSource, the identical buyer help portal compromised in December to realize entry to PowerSchool’s faculty data system.

CrowdStrike mentioned, nevertheless, that there’s not sufficient proof to conclude this is similar menace actor liable for December’s breach on account of inadequate logs.
