Sax LLP, a top-ranked US accounting firm, has begun notifying over 220,000 individuals that sensitive personal data was compromised in a cyberattack that went undisclosed for more than 16 months. Based in New Jersey, Sax is a top 100 accounting and advisory company with an annual revenue exceeding $100 million. The firm revealed that it had detected a network intrusion on 7 August 2024, and the investigation took well over a year to identify contact information for the impacted individuals.

According to Sax, the compromised information varies for each individual but can include name, date of birth, SSN, driver’s licence or state identification number, and passport number. The company is offering impacted individuals 12 months of free credit monitoring, dark web monitoring, credit protection, and identity restoration services.
