Rhysida Ransomware Gang Attacks Lumberton Independent School District
The Rhysida ransomware gang has attacked Lumberton Independent School District. The Lumberton Independent School District (Lumberton ISD) is a public school district located in Lumberton, Texas, United States. It serves the educational needs of students residing in Lumberton and its surrounding areas. Lumberton ISD is responsible for providing K-12 education to the students within its designated boundaries.
Rhysida posted Lumberton Independent School District to its data leak site on July 27th but provided no further details. The Rhysida ransomware group emerged in May 2023 and introduced a victim support chat portal on the TOR network. They present themselves as a "cybersecurity team" and claim to be helping their victims by targeting their systems and exposing potential security issues.
Methods of Attack
Rhysida deploys its ransomware through various methods, including Cobalt Strike or similar frameworks, as well as phishing campaigns. Analysis of Rhysida ransomware samples suggests that the group is still in the early stages of development. The ransomware lacks certain standard features in contemporary ransomware, such as VSS removal. However, the group follows the practices of modern multi-extortion groups by threatening to distribute the stolen data publicly.
Execution and Ransom Process
Upon execution, Rhysida displays a cmd.exe window and scans all files on local drives. Victims are instructed to contact the attackers using the TOR-based portal and their unique identifier provided in the ransom notes. The group only accepts payment in Bitcoin (BTC) and provides victims with instructions on purchasing and using BTC through the victim portal. Victims are also given an additional form on the payment portal to provide authentication and contact details to the attackers.
The Rhysida ransom notes are written as PDF documents and placed in the affected folders on the targeted drives.
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.
