Description

In November Princeton University’s donor database was breached, exposing email addresses, phone numbers, street addresses, and information about donations. This occurred less than a month after those claiming responsibility for a breach at the University of Pennsylvania released thousands of files including memos about donors. The breach at Princeton was reported by the Chronicle of Philanthropy in January 2026. Princeton declined to discuss its data breach or the methods it is using to rebuild trust.

The breach exposed personal data of donors, raising concerns about trust and future giving. According to a BBB Wise Giving Alliance survey cited in the article, 28% of donors said they would not donate again if their data were stolen. Fifty‑two percent said they would hold off donating until they were satisfied the issue had been resolved. Research by Christoph Schiller indicated that organizations suffering a data breach could experience reputational harm lasting up to four years. The article notes that such breaches can undermine fundraising and damage relationships with supporters.

Princeton did not publicly detail its response, but experts consulted by the Chronicle outlined steps nonprofits can take to rebuild trust. These steps include following applicable state data privacy laws, issuing a sincere and genuine apology, being transparent about what went wrong and how it will be fixed, targeting messaging to those most affected by the breach, engaging with media to cover efforts to address the breach, providing ongoing updates with specific benchmarks such as timelines for new systems or investigation reports, improving security through software, backups, cybersecurity insurance, and staff training, and maintaining long‑term engagement to demonstrate improved data protection. Because Princeton declined to discuss its actions, the specifics of what it actually undertook remain unspecified.
