- Ericsson US confirms third-party data breach
- Sensitive customer data, including SSNs and exposed financial information
- The company offers free identity protection services through an ID document
Ericsson’s US arm has confirmed it suffered a third-party data breach that caused it to lose sensitive data on an undisclosed number of its customers.
In a data breach notification letter sent to affected individuals, Ericsson US said it spotted “a suspicious event” and potentially 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 strengthen security and minimize the risk of a similar incident occurring in the future,” but it did not specify what those measures were.

Free identity theft protection
The investigation showed that the unidentified actors stole a “limited subset” of customer data, but Ericsson US did not detail what it was, only saying it included people’s names.
She filed multiple data breach notifications with different U.S. Attorney General’s offices, and in her Texas filing she said more than 4,000 people were affected, losing their names, addresses, Social Security numbers, driver’s license numbers, identification numbers, financial information, medical information and dates of birth.
“Please note that our service provider has told 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 services to affected individuals, through IDX, for at least 12 months. The service includes credit monitoring, dark web monitoring, a $1 million lost identity refund policy, and a fully managed identity theft recovery service.
Users have until June 9, 2026 to register.
As of press time, no malicious actor has taken responsibility for this attack, although given the status Ericsson US enjoys in its industry, it is likely only a matter of time before someone does. Unless, of course, the company paid a ransom demand – which is very unlikely.
