Nutec Group Targeted by BianLian Ransomware in Major Data Breach
Company Overview
Nutec Group, a leading provider of industrial heating solutions, has recently become the latest victim of a ransomware attack by the notorious BianLian group. Founded in 1975, Nutec specializes in innovative and efficient thermal solutions for various industries, helping clients manage heating costs, achieve energy savings, and reduce their carbon footprint. With operations in over 50 countries, Nutec is recognized for its commitment to quality and customer-centric services, particularly in sectors like automotive, aerospace, and petrochemicals.
Details of the Attack
In May 2024, Nutec Group experienced a significant cyberattack executed by the BianLian ransomware group. The attackers exfiltrated approximately 204 GB of sensitive data, including business, client, financial, and technical information. This incident is part of BianLian's broader strategy of leveraging data theft for extortion, rather than the traditional encryption-based ransom demands. The stolen data is being used to pressure Nutec into paying a ransom to prevent the public release of this information.
BianLian: A Growing Threat
BianLian, active since mid-2022, has evolved from a banking trojan to a sophisticated ransomware group focusing on data extortion. The group is known for its aggressive tactics, which include gaining access through compromised Remote Desktop Protocol (RDP) credentials, often obtained via phishing or purchased from initial access brokers. Once inside, BianLian uses custom backdoors and remote management tools like TeamViewer and AnyDesk to maintain control over compromised networks. The group also disables antivirus software and modifies system settings to avoid detection.
Vulnerabilities and Impact
The attack on Nutec highlights significant vulnerabilities in cybersecurity practices, particularly in the use of remote access tools and the management of credentials. BianLian's ability to exploit these weaknesses underscores the need for robust cybersecurity measures, such as regular security audits, restricted use of RDP, and comprehensive employee training on recognizing phishing attempts.
Nutec Group now faces the challenging task of mitigating the impact of this breach, safeguarding its data, and reinforcing its cybersecurity defenses to prevent future incidents.

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.
