What happened in the LIGO data breach
According to its notice letter, LIGO engages the accounting firm Ernst and Young LLP ("EY") to provide professional services, and EY obtained certain information from LIGO as part of that engagement. Between March 28 and April 12, 2026, an unauthorized person accessed EY's management platform. The letter states that only EY's platform was accessed and that the unauthorized person did not access LIGO's computer systems.
On August 6, 2026, EY determined that data files it had obtained from LIGO were affected, and that some of those files included personal and financial information for certain individuals. The letter says EY told LIGO on August 7, 2026 that some of its affected files included personal and financial information for certain individuals. Between August 31 and September 2, 2026, EY provided LIGO with specific information indicating which individuals' information was included in the affected files. LIGO's letter is dated October 1, 2026, more than five months after the unauthorized access ended.
The letter says the information that might have been accessed includes the recipient's name, an address, and Social Security number. The Massachusetts filing lists name, address and Social Security number. LIGO is offering 36 months of one-bureau credit monitoring through Financial Shield, with enrollment open until December 30, 2026. Whether LIGO and its vendor took reasonable steps to protect this information is among the issues being evaluated.
