What Caused the Ally Bank Data Breach?

The Ally Bank data breach was only recently announced, and more information is expected in the near future. However, Ally Bank’s filing with the Attorney General of Massachusetts provides some important information on what led up to the breach. According to this source, on April 23, 2024, Ally Bank learned that an unauthorized party was able to access personal information belonging to certain customers.

While the Ally Bank data breach letter is brief, it appears that the incident stemmed from an incident at one of the bank’s third-party vendors. Once Ally Bank learned about the incident, it followed up with the vendor to ensure that the matter was investigated.

Ultimately, Ally Bank was able to confirm that the confidential information of certain Ally Bank customers was subject to unauthorized access.

After learning that sensitive consumer data was accessible to an unauthorized party, Ally Bank reviewed the compromised files to determine what information was leaked and which consumers were impacted. While the breached information varies depending on the individual, it may include your name, Social Security number, date of birth, and auto account number.

On May 23, 2024, Ally Bank sent out data breach letters to anyone who was affected by the recent data security incident. These letters should provide victims with a list of what information belonging to them was compromised.
