United States-based Nokia-owned SAC Wireless has started sending
notification letters to its current and former employees to inform them of
a data breach that might have impacted them.

In a notification letter filed with the Maine Attorney General's Officer,
the  company said personal information of roughly 6500 individuals was
compromised during a ransomware attack that was identified in mid-June.

An investigation launched into the incident, the company says, has revealed
that the attackers first compromised SAC Wireless’ systems on April 13.

The threat actor, known for the use of Conti ransomware, uploaded tools
onto the firm’s cloud storage, and deployed ransomware only two months
later, on June 13, SAC Wireless disclosed.

While the investigation continues, the company says the attackers were able
to exfiltrate large amounts of personal information relating to current and
former SAC Wireless employees.

The compromised data includes names, birth dates, addresses, email
addresses, phone numbers, driver’s license numbers, passport or military ID
numbers, work information, medical history, Social Security Numbers, data
on health insurance policy, license plate numbers, tax return information,
digital signatures, and more.

“To the extent that one of your dependents or beneficiaries was included on
an SAC Wireless health plan, their personal information may also have been
compromised,” the company said.

In addition to taking systems offline to limit the damage incurred by
ransomware, the company provided additional training to employees, improved
network and endpoint monitoring, expanded multi-factor authentication, and
improved threat-hunting and detection capabilities.

The Conti ransomware group claims to have stolen more than 250 GB of data
from SAC Wireless. On their leak site, the cybergang threatens to make the
exfiltrated data public unless Nokia pays the demanded ransom.

Headquartered in Chicago, IL, SAC Wireless was bought by Nokia in 2014. The
company provides wireless network design, deployment, and maintenance
services to telecommunication companies in the United States.
