Denver Fiber Internet Provider Faces Dismissed Data Breach Lawsuit On June 25, 2026, a customer of a Denver-based fiber internet provider voluntarily dismissed a proposed class action lawsuit in the U.S. District Court for the District of Colorado. The suit had alleged that the company failed to safeguard customers' sensitive personal data during a cyberattack and delayed notifying affected individuals for five months. The case centered on claims that the provider’s inadequate security measures led to the exposure of customer information, with plaintiffs arguing that the prolonged notification period exacerbated potential harm. No further details on the breach’s scope or the number of impacted customers were disclosed. The dismissal follows a growing trend of legal challenges against companies over data security practices, particularly in cases involving delayed breach disclosures. The outcome leaves unresolved questions about the provider’s handling of the incident and its compliance with data protection standards.

WideOpenWest (WOW!) experienced a significant breach in early 2025 when Arkana Ransomware exfiltrated two extensive databases containing approximately 403,000 and 2.2 million customer records respectively. The threat actors also gained unauthorized control over critical backend infrastructure, including WOW!’s AppianCloud and Symphonica platforms. The ransomware operation follows a three-phase extortion model comprising Ransom, Sale, and Leak stages, each designed to maximize pressure on victims to comply with their demands.
