The personal information of thousands of Marines, sailors and civilians, including bank account numbers, was compromised in a major data spillage emanating from U.S. Marine Corps Forces Reserve.
Roughly 21,426 people were impacted when an unencrypted email with an attachment containing personal confidential information was sent to the wrong email distribution list Monday morning.
The compromised attachment included highly sensitive data such as truncated social security numbers, bank electronic funds transfer and bank routing numbers, truncated credit card information, mailing address, residential address and emergency contact information, Maj. Andrew Aranda, spokesman for Marine Forces Reserve said in a command release.
That email was a roster sent out by the Defense Travel System, or DTS, Marine Corps Times has learned. DTS is a Defense Department system that assists military and civilian defense personnel with travel itineraries and settling expenses from official authorized trips.
“It was very quickly noticed and email recall procedures were implemented to reduce the number of accounts that received it,” Aranda said.
The email containing the data was sent within the usmc.mil official unclassified Marine domain, but also to some civilian accounts.
Personal information can be used by criminals or entities to steal identities, commit bank and credit fraud, or phishing schemes.
