Ransomware Group Inc Claims Attack on Kansas Utility Provider Rainbow Communications
In November 2025, ransomware group Inc took responsibility for a cyberattack on Rainbow Communications, a rural phone and internet provider serving northeast Kansas. The incident, disclosed by Rainbow on November 16, caused service disruptions for customers before full restoration by November 19.
Inc claimed to have stolen 200 GB of data, including accounting, HR, and customer records, and posted sample documents on its leak site as proof. Rainbow has not confirmed the breach, and key details—such as the number of affected individuals, ransom demands, or the attack vector—remain undisclosed.
Inc, active since July 2023, specializes in spear phishing and exploiting software vulnerabilities, encrypting systems while exfiltrating data. In 2025 alone, the group has claimed 54 confirmed attacks, including recent breaches at Valley View Independent School District (68 GB stolen) and Persante Health Care. An additional 289 unconfirmed claims this year suggest broader targeting.
The attack on Rainbow adds to a growing trend of ransomware incidents against U.S. utilities. In 2025, researchers documented three confirmed attacks on private utility firms and four on government providers, including breaches by Qilin, RansomHub, BlackSuit, and Clop. These incidents risk disrupting billing, communications, and service delivery, with potential fallout including extended downtime and fraud risks for customers.
Rainbow Communications, based in Everest, Kansas, serves over 20 communities in the region, including Atchison, Hiawatha, and Sabetha. The full scope of the breach’s impact remains unclear pending further investigation.
