Texas Dow Employees Credit Union reports MOVEit related breach 1.5 years after the incident

Take action: It's unfathomable how or why the third-party vendor did not report the incident earlier, given the massive size of the incident during 2023. If you receive an incident report from a vendor a year after the incident, stop using that vendor immediately. They can't be trusted.

The Texas Dow Employees Credit Union (TDECU) is reporting a data breach from May 2023, related to the MOVEit Transfer software that exposed the personal information of 500,474 members.

The breach, part of a larger global attack of vulnerability in MOVEit software that started in June 2023, was only discovered by TDECU on July 30, 2024. The incident involved a third-party vendor that facilitated data transfers for the credit union.

During the breach, attackers accessed and potentially exfiltrated sensitive member data, including:

  • Full names
  • Dates of birth
  • Social Security numbers
  • Bank/financial account numbers
  • Credit/debit card numbers
  • Driver’s licenses/government IDs
  • Taxpayer identification numbers

TDECU claims that there is no current evidence of identity or financial fraud related to this breach. The massive delay in detecting the breach—over a year—raises concerns about prolonged exposure and the potential for future risks like identity theft or financial fraud.
