McGraw-Hill suffered a data breach due to a Salesforce misconfiguration, resulting in unauthorized access to internal data. The compromised information was limited and non-sensitive, not affecting customer databases or internal systems. ShinyHunters, the notorious group behind the extortion threat, claimed to have obtained 45 million Salesforce records containing personally identifiable information (PII). McGraw-Hill has secured affected webpages and is working closely with Salesforce to strengthen protections. The incident highlights the importance of robust security measures and ongoing vigilance in the face of evolving cyber threats.
The news industry has witnessed numerous high-profile data breaches in recent years, with companies like Rockstar Games and Hims & Hers falling victim to the malicious activities of extortion groups. The latest casualty is McGraw-Hill, a prominent education company that offers textbooks, digital learning platforms, and K-12 school and university systems. In an April 2026 statement, the company revealed that hackers exploited a Salesforce misconfiguration, resulting in unauthorized access to internal data.
McGraw-Hill assured the public that the breach did not affect its Salesforce accounts, customer databases, or internal systems, indicating that the compromised information was limited and non-sensitive. The company's spokesperson stated, "McGraw-Hill recently identified unauthorized access to a limited set of data from a webpage hosted by Salesforce on its platform. This activity appears to be part of a broader issue involving a misconfiguration within Salesforce’s environment that has impacted multiple organizations that work with Salesforce."
The statement further clarified that the exposed information did not contain Social Security numbers (SSNs), financial account information, or student data from McGraw-Hill's educational platforms. The company emphasized its commitment to protecting sensitive information, stating, "Importantly, this did not involve unauthorized access to McGrow-Hill’s Salesforce accounts, customer databases, courseware, or internal systems."
The incident gained attention following an extortion threat from the notorious group ShinyHunters. The organization announced on its dark-web portal that it had obtained 45 million Salesforce records containing personally identifiable information (PII), contradicting McGraw-Hill's claim that the compromised data was not sensitive in nature. ShinyHunters threatened to leak the stolen data unless a ransom is paid.
McGraw-Hill swiftly secured the affected webpages after detecting unauthorized activity, and it has been working closely with Salesforce to strengthen protections and ensure the issue is fully addressed. The company's proactive response underscores its dedication to safeguarding sensitive information and upholding cybersecurity standards.
The incident serves as a reminder of the importance of robust security measures and ongoing vigilance in the face of evolving cyber threats. As organizations continue to navigate the complexities of data protection, it is essential for companies like McGraw-Hill to prioritize cybersecurity protocols and invest in comprehensive security solutions.
In recent months, ShinyHunters has carried out several high-profile breaches targeting prominent organizations such as Rockstar Games, Hims & Hers, the European Commission, Telus Digital, Wynn Resorts, Canada Goose, Match Group, Panera Bread, and CarGurus. The group's brazen tactics have raised concerns among cybersecurity experts and business leaders alike.
The breach of Infinite Campus in March further highlights the growing threat landscape and the need for companies to maintain robust security protocols. As organizations strive to protect sensitive information, they must remain vigilant and proactive in addressing emerging threats.
In conclusion, McGraw-Hill's data breach serves as a wake-up call for businesses to reassess their cybersecurity posture. The incident underscores the importance of investing in comprehensive security solutions and prioritizing ongoing vigilance in the face of evolving cyber threats.
McGraw-Hill has confirmed a data breach following an extortion threat from ShinyHunters, but assures that the compromised information is limited and non-sensitive. The company has secured affected webpages and is working closely with Salesforce to strengthen protections.
