Ransomware Attack Overview

Frontier Communications was targeted by RansomHub, a cybercrime group, in a ransomware attack. RansomHub claimed to have leaked data of over 2 million customers, including sensitive information such as names, addresses, emails, SSNs, credit scores, dates of birth, and phone numbers. Despite being given a deadline to contact the group, Frontier did not respond, leading to the data leak.

Ransomware Group Profile

RansomHub is an emerging ransomware group operating as a Ransomware-as-a-Service (RaaS) entity. They have attacked various countries and industries, including the US, Brazil, and healthcare-related institutions. RansomHub distinguishes itself by substantiating its claims with data leaks. Their ransomware strains are written in Golang, a language choice that sets them apart in the cyber threat landscape.

Company Vulnerabilities

Telecommunications companies like Frontier Communications are attractive targets for cyber attacks due to the extensive personal information they collect and store. Breaching telecoms enables threat actors to access customer proprietary network information (CPNI) and execute more potent cyber attacks. Additionally, the company's integration of technology and assets from acquisitions may pose cybersecurity challenges.


Recent Ransomware Attacks

The Recent Ransomware Attacks (RRA) site acts as a watchtower, providing you with near real-time ransomware tracking of attacks, groups and their victims. Given threat actors’ overarching, lucrative success so far, ransomware attacks have become the most ubiquitous, and financially and informationally impactful cyber threat to businesses and organizations today.

The site’s data is generated based on hosting choices of real-world threat actors, and a handful of other trackers. While sanitization efforts have been taken, we cannot guarantee 100% accuracy of the data. Attack updates will be made as source data is reported by reputable sources. By viewing, accessing, or using RRA you acknowledge you are doing so at your own risk.
