Massive Data Breach Hits Connex Credit Union: 172,000 Affected with Stolen Personal and Financial Info
August 11, 2025
The breach has affected 172,000 individuals, with personal and financial information stolen by unknown attackers.
The stolen data includes names, account numbers, debit card information, Social Security numbers, and government IDs used for account setup.
Connex Credit Union, one of Connecticut's largest credit unions with over 70,000 members and assets exceeding $1 billion, has reported a significant data breach.
Despite the breach, Connex has stated that there is no evidence of unauthorized access to member accounts or funds.
The breach occurred between June 2 and June 3, 2025, and was discovered on June 3, prompting notifications to affected individuals via U.S. Mail.
It remains unclear who perpetrated the attack or if it was a ransomware incident, as no known threat group has claimed responsibility.
In response to the breach, Connex has issued a scam alert warning members about ongoing phishing attacks where scammers impersonate Connex employees.
Connex's website cautions members about potential scam calls and texts, although the relationship to the breach is still unclear.
This incident follows a series of data breaches linked to the ShinyHunters extortion group, which has employed vishing and social engineering tactics.
Additionally, the insurance sector has faced cybersecurity threats from the Scattered Spider hacker collective, which has recently shifted its focus to aviation and retail sectors.
