Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the PowerSchool breach identified under incident ID INSPOW1778179137.
The analysis begins with a detailed overview of PowerSchool's information like the linkedin page: https://www.linkedin.com/company/powerschool-group-llc, the number of followers: 159772, the industry type: E-Learning Providers and the number of employees: 3504 employees
After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 100 and after the incident was 100 with a difference of 0 which is could be a good indicator of the severity and impact of the incident.
In the next step of the video, we will analyze in more details the incident and the impact it had on PowerSchool and their customers.
Wake County Public Schools recently reported "North Carolina Data Breaches Surge, Including Major Education Sector Attacks", a noteworthy cybersecurity incident.
North Carolina has seen a surge in data breaches, with the state’s Department of Justice (NCDOJ) reporting 2,349 incidents in 2025 impacting over nine million residents.
The disruption is felt across the environment, affecting Canvas (Instructure) and PowerSchool, and exposing student and staff data, millions of records, with nearly millions records at risk, plus an estimated financial loss of $431.6 million (statewide losses in 2024).
In response, and began remediation that includes MFA implementation, network segmentation and regular backups.
The case underscores how teams are taking away lessons such as Educational institutions are prime targets due to sensitive data and reliance on third-party vendors. Lack of MFA and vendor security gaps are critical vulnerabilities. Phishing is a major attack vector, necessitating training and simulations, and recommending next steps like Implement multi-factor authentication (MFA), Conduct phishing simulation training and Address vendor security gaps.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
MITRE ATT&CK® Correlation Analysis
Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Phishing (T1566) with high confidence (90%), supported by evidence indicating majority of these breaches stem from hacking and phishing attacks, Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), supported by evidence indicating canvas, a statewide learning management system operated by Instructure, and Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating lack of multi-factor authentication (MFA) in PowerSchool attack. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate confidence (60%), supported by evidence indicating lack of MFA enabled credential-based attacks and Unsecured Credentials: Credentials in Files (T1552.006) with moderate confidence (50%), supported by evidence indicating third-party vendor vulnerabilities in educational systems. Under the Lateral Movement tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate to high confidence (70%), supported by evidence indicating breach via Canvas and PowerSchool systems. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating student and staff data, millions of records compromised and Data from Information Repositories (T1213) with moderate to high confidence (80%), supported by evidence indicating canvas and PowerSchool systems store vast amounts of sensitive data. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating data breaches impacting over nine million residents and Transfer Data to Cloud Account (T1537) with moderate confidence (60%), supported by evidence indicating cybercriminals targeting sensitive data for extortion or resale. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate to high confidence (70%), supported by evidence indicating type such as Ransomware, ransom paid in PowerSchool incident and Defacement (T1491) with lower confidence (40%), supported by evidence indicating disruption to educational institutions. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (60%), supported by evidence indicating lack of MFA and vendor security gaps. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
