Data belonging to more than 800,000 United States Postal Service employees has been compromised in a computer network breach.
The breach, discovered in mid-September, is being investigated by the FBI. Remediation of the hack did not begin until this weekend, although planning began immediately, according to the agency.
“Acting too quickly could have caused more data to be compromised,” USPS spokesman David Partenheimer said in a statement.
Names, dates of birth, Social Security numbers, addresses, dates of employment and other information are among the compromised data. According to the agency, employees at all levels were affected, from letter carries to the postmaster general.
However no customer credit card information from online purchases at usps.com or at post offices were exposed.
New security measures were implemented over the weekend to prevent future breaches, Partenheimer said. Enacting the new safeguards caused system outages and slowed the delivery of external email.
Notification of employees began on Monday. USPS is providing free credit-monitoring services for one year.
