29,000 Cambridge Subscribers Compromised: The INC Ransom Attack That Knocked Out Harvard and MIT's Backup Alert Layer
On November 26, 2025, Cambridge Public Safety agencies announced that the CodeRED emergency notification platform — used by Cambridge, Harvard, and MIT as the municipal-level alert backup layer — had been hit by a ransomware attack claimed by the INC Ransom group. More than 29,000 Cambridge residents were enrolled in CodeRED, and the breach exposed names, phone numbers, email addresses, and passwords. Cambridge ran its own alerting infrastructure for two weeks while CodeRED was offline; the system was restored on December 11, 2025 on a new platform with all passwords forcibly reset.
