- Ericsson USA confirms third-party data breach
- Sensitive customer data including SSNs and financial information exposed
- The company offers free identity protection services through ID
The US arm of Ericsson has confirmed it suffered a third-party data breach which saw it lose sensitive data on an undisclosed number of its customers.
In a data breach notification letter sent out to affected individuals, Ericsson US said it detected “a suspicious incident” and potential unauthorized access to its systems on April 28, 2025.
The company launched an investigation, brought in third-party security experts, notified the FBI, and also implemented “measures to improve security and minimize the risk of a similar incident occurring in the future,” but it did not elaborate on what those measures were.

Free identity theft protection
The investigation found that the unidentified actors stole a “limited subset” of customer data, but Ericsson US did not detail their nature, other than to say it included people’s names.
It filed multiple data breach notifications with various US Attorney’s Offices and, in its Texas filing, said more than 4,000 people were affected, losing names, addresses, SSNs, driver’s license numbers, ID numbers, financial information, medical information and dates of birth.
“Please note that our service provider has represented to us that they have no evidence of misuse of potentially affected information since the time of the incident,” the letter said.
To mitigate the damage, Ericsson US will offer free identity theft protection to affected individuals through IDX for at least 12 months. The service includes credit monitoring, dark web monitoring, a $1 million identity fraud loss refund policy and a fully managed identity theft recovery service.
Users have until June 9, 2026 to sign up.
As of press time, no threat actors have claimed responsibility for this attack, although given the stature Ericsson US holds in its industry, it’s likely only a matter of time before someone does. Unless, of course, the company has paid a ransom demand – which is highly unlikely.
