Connex Credit Union Data Breach Affects 172,000 Members in Connecticut

Connex Credit Union, one of Connecticut's largest with over $1 billion in assets and more than 70,000 members, experienced a data breach in early June 2025 that exposed sensitive personal and financial information of approximately 172,000 members across multiple states. The breach, discovered on June 3, involved unauthorized access to files containing names, account numbers, Social Security numbers, debit card information, and government IDs, although Connex stated there is no evidence that member accounts or funds were accessed or compromised. The credit union promptly notified affected members starting August 7, offering 12 to 24 months of complimentary credit monitoring and identity protection services and warning members about ongoing phishing scams impersonating Connex employees. Connex engaged independent experts to investigate the incident and has emphasized its commitment to securing its network and assisting affected members. The breach has prompted legal interest, with attorneys seeking affected individuals to explore the possibility of a class action lawsuit for damages resulting from the incident. Despite the significant breach, no ransomware or extortion demands have been reported in connection with this cyberattack.
