Lumen Technologies Data Breach Class Action

At Console & Associates, our data breach lawyers are closely examining the recent Lumen Technologies data breach. This data breach was disclosed following a cyber security incident at Lumen Technologies, which may have affected numerous individuals, potentially exposing sensitive personal identifiable information.

What Happened?

A recent report from the Montana Attorney General's website states that the Lumen Technologies data breach occurred due to a cyber security incident. According to the filing, Lumen first detected potential security issues on January 17, 2025, prompting action to secure their network and launch an investigation.

The investigation revealed that unauthorized access to the company's computer systems occurred over a nearly three-week period, between November 15, 2024, and December 4, 2024. During this timeframe, an unauthorized party was able to access and potentially extract files containing confidential consumer information from Lumen's network infrastructure.

While the public notice filed with the Montana Attorney General does not specify the exact categories of compromised data, Lumen has indicated that sensitive consumer information was accessed during the breach. The company conducted a comprehensive review of the affected files to identify which individuals had their information exposed and what specific data elements were compromised for each person.

Data breach letters were sent out by Lumen Technologies on March 6, 2025, informing affected individuals about the nature of the incident and the specific types of personal information that may have been compromised in their particular case.
