Alphv Ransomware Attack on Horwitz, Horwitz & Associates

The ransomware group Alphv, also known as Blackcat, has claimed responsibility for an attack on Horwitz, Horwitz & Associates, a law firm based in Illinois. The firm, which specializes in personal injury cases, has been recognized as one of the premier personal injury law firms in the state and has achieved significant victories in catastrophic injury cases.

The attack on Horwitz, Horwitz & Associates is part of a larger campaign by Alphv, which has targeted over 1,000 entities, including Fidelity National Financial, Henry Schein, and Seiko. The group has been particularly active in the healthcare sector, causing significant disruptions to pharmacies and hospitals.

Alphv is known for its advanced social engineering techniques and the use of uniform resource locators (URLs) to live-chat with victims, conveying demands and initiating negotiations. The group often exfiltrates data and extorts victims without deploying ransomware, sometimes deleting data in the process.

The attack on Horwitz, Horwitz & Associates highlights the vulnerability of law firms and other professional services to ransomware attacks. As the legal sector increasingly relies on digital tools and data-driven strategies, firms must prioritize cybersecurity measures to protect sensitive client information and maintain business continuity.


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.
