Ransomware Attack on GWF Frankenwein by RA Group

Company Profile

GWF Frankenwein, officially known as Winzergemeinschaft Franken eG (GWF), is a prominent cooperative of over 2,100 winegrowers based in Kitzingen, Germany. Founded in 1959, GWF specializes in the production and distribution of high-quality wines, including a variety of Franconian white and red wines. The cooperative is one of the six largest of its kind in Germany, leveraging the mild climate and mineral-rich soils of regions between Spessart and Steigerwald, Saaletal, and Tauberfranken.

Details of the Ransomware Attack

The cyberattack on GWF Frankenwein's website,, was orchestrated by a ransomware group known as RA Group. Utilizing sophisticated ransomware derived from the leaked Babuk code, the attackers managed to exfiltrate approximately 18 GB of sensitive data. This data breach included critical legal, financial, and employee documents, posing a severe threat to the privacy and security of the company and its stakeholders.

RA Group's Modus Operandi

RA Group, emerging in the cybercrime scene in May 2023, has quickly established itself by targeting a variety of sectors across Eastern Asia, Europe, and the United States. The group is known for its double extortion tactic; not only does it encrypt the victim's files, making them inaccessible, but it also threatens to publish the stolen data unless a ransom is paid. This method increases the likelihood of compliance from the victims.

The ransomware used by RA Group, identifiable by the ".GAGUP" file extension, employs advanced cryptographic techniques such as curve25519 and the eSTREAM cipher hc-128 algorithm. The group's initial penetration methods likely include exploiting vulnerabilities in publicly exposed systems, using stolen remote access credentials, or purchasing access from other cybercrime syndicates.

Potential Vulnerabilities at GWF Frankenwein

While specific vulnerabilities that were exploited in this attack are not detailed, common entry points for such ransomware attacks include insufficiently secured remote access points, outdated software systems, and the lack of robust multi-factor authentication mechanisms. For a company like GWF Frankenwein, which engages heavily in online commerce and digital marketing, ensuring the security of their IT infrastructure is crucial to safeguard against such sophisticated cyber threats.


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.
