Harvard University has confirmed a data breach involving its alumni and donor database, following a phone phishing attack that has raised concerns about cybersecurity at elite institutions.
Harvard University has reported a significant data breach affecting its alumni and donor database, marking the second cybersecurity incident at the institution in recent months. The breach was the result of a phone phishing attack that compromised sensitive information related to alumni, donors, faculty, and some students.
Elite universities, including Harvard, Princeton, and Columbia, invest heavily in research, talent, and digital infrastructure. However, these institutions have increasingly become targets for cybercriminals seeking access to vast databases filled with personal information and donation records. Recent months have seen a troubling pattern of breaches across Ivy League campuses, highlighting vulnerabilities in their cybersecurity measures.
In a notification posted on its website, Harvard confirmed that an unauthorized party accessed information systems used by Alumni Affairs and Development. The breach occurred after an individual was tricked into providing access through a phone-based phishing attack. “On Tuesday, November 18, 2025, Harvard University discovered that information systems used by Alumni Affairs and Development were accessed by an unauthorized party as a result of a phone-based phishing attack,” the university stated. “The University acted immediately to remove the attacker’s access to our systems and prevent further unauthorized access.”
The compromised data includes personal contact details, donation histories, and other records integral to the university’s fundraising and alumni operations. Given that Harvard routinely raises over a billion dollars annually, the exposed database is considered one of its most valuable assets, making the breach particularly concerning.
This incident follows an earlier investigation in October, when Harvard looked into reports of its data being involved in a broader hacking campaign targeting Oracle customers. This earlier warning underscored the university’s high-risk status, and the latest breach further confirms the need for enhanced cybersecurity measures.
Harvard is not alone in facing these challenges. Other Ivy League institutions have reported similar incidents in quick succession. On November 15, Princeton disclosed that one of its databases, linked to alumni, donors, students, and community members, had been compromised. Additionally, the University of Pennsylvania reported unauthorized access to its information systems related to development and alumni activities on October 31. Columbia University has faced even larger repercussions, with a breach in June exposing personal data of approximately 870,000 individuals, including students and applicants.
These repeated attacks illustrate how universities have become predictable targets for cybercriminals. They store sensitive information, including identities, addresses, financial records, and donor information, within sprawling IT systems. A single mistake, such as a weak password or a convincing phone call, can create an entry point for attackers.
As these incidents continue to unfold, it is clear that universities must strengthen their defenses and adopt more proactive monitoring strategies. While it is impossible to completely prevent breaches, individuals can take steps to protect their own information. Implementing two-factor authentication (2FA) adds an extra layer of security to accounts, making it more difficult for attackers to gain access even if they acquire a password.
Using a password manager can also help create and store strong, unique passwords for each site, preventing a single compromised password from unlocking multiple accounts. Additionally, individuals should regularly check if their email addresses have been exposed in past breaches and change any reused passwords immediately if a match is found.
In light of these ongoing threats, it is advisable to limit the amount of personal information shared publicly and consider utilizing data removal services to monitor and erase personal information from the internet. While no service can guarantee complete removal, these services can help reduce the risk of identity theft and make it more challenging for attackers to target individuals.
As the landscape of cyber threats continues to evolve, universities like Harvard must adapt to protect the sensitive data they hold. The recent breach serves as a reminder of the vulnerabilities that persist even within the most well-funded institutions. Until stronger defenses are implemented, it is likely that more incidents will occur, prompting further investigations and raising questions about the security of personal data shared with these universities.
