Six Weeks of Inactivity and 37 Years of History Lost: Cyberattack Forces German Textile Firm ZEGO into Bankruptcy

A devastating cyberattack has forced the long-established German textile company ZEGO Textilveredelungszentrum into bankruptcy proceedings after nearly six weeks without production, effectively ending 37 years of operations.

The Bavarian firm, which specialized in the finishing and processing of fabrics for the automotive industry, manufacturers of workwear, and producers of technical textiles, was unable to withstand the financial consequences of the prolonged shutdown.

The attack occurred on 29 March 2026 and brought production to a near-complete halt for almost six weeks. Company leadership explored multiple avenues to offset losses and keep the business afloat, but the extended downtime created an overwhelming financial burden that proved impossible to overcome.

Managing Director Johannes Zenglein described the move to seek creditor protection as one of the most painful decisions in the company’s history, stating that the attack had so severely damaged ZEGO’s financial position that continuing operations without insolvency proceedings was no longer viable.

The company has not disclosed the nature of the attack. It remains unknown whether the perpetrators used ransomware, who was responsible, or whether any customer or employee data was accessed. Management has only confirmed that the production stoppage itself placed the enterprise on the verge of closure.

The initiation of bankruptcy proceedings does not necessarily mean the final liquidation of ZEGO. The company intends to maintain production activities while insolvency administrators search for ways to restructure the business, protect jobs, and retain clients and suppliers.

Cyberattacks have previously disrupted factories and production lines, yet companies rarely acknowledge that operational downtime was the direct cause of their collapse. One of the most prominent examples is the bankruptcy of British logistics provider KNP Logistics, which operated for 158 years until attackers gained access via an employee password, encrypted systems, and left more than 700 people without work. Payment of the ransom failed to save the enterprise.

IT Elements 2026 Conference: Ransomware Accounts for 69% of Incidents as Businesses Struggle with Backup Protection and AI Workloads

The fourth IT Elements conference opened in Moscow on September 9, focusing on business continuity after cyberattacks, infrastructure failures, and ransomware incidents. Jet CSIRT data showed that ransomware was responsible for 69% of confirmed incidents in the first half of 2026, with the majority occurring in the second quarter. Experts discussed the challenges of protecting backup copies from compromise, the frequent gap between stated RTO targets and real-world recovery times, and decision-making processes during major outages. The event also covered corporate AI agents, stressing the need for strong Data Governance, Data Quality, and DataOps practices to avoid unreliable model outputs. Research from Jet Infosystems and AC IKS revealed that over 30% of companies have already allocated dedicated network segments for AI workloads, with power demands reaching 80-200 kW per rack. On the networking track, testing of Eltex and EcoRouter devices showed adequate performance in standard scenarios but highlighted the lack of a universal domestic solution. The conference concluded with discussions on workforce changes, noting that AI is altering career paths for junior specialists and increasing demand for professionals who understand business context and can critically evaluate model results.

Ransomware Operators Linked to The Gentlemen Deploy TukTuk C2 Framework for Espionage and Credential Theft

Operators associated with the ransomware group The Gentlemen have adopted a new command-and-control framework called TukTuk to steal credentials, monitor compromised systems, and prepare environments for ransomware deployment. The framework was discovered on a server that also hosted tools for disabling EDR solutions, research on vulnerable drivers, and data apparently stolen from two large organizations. TukTuk includes agents for both Windows and Linux, along with its own backend and management panel that allows remote command execution, file transfers, screen capture, and device tracking through a single interface. One notable feature displays a fake Windows Security window on the victim's machine to capture entered credentials and send them directly to the attackers' panel. Researchers identified a DLL sideloading technique that abuses the legitimate Greenshot.exe executable to load a malicious log4net.dll library and launch the TukTuk agent. The server also contained EDRKiller, WarsawKiller, and UnknownKiller tools, plus materials on BYOVD attacks that leverage vulnerable legitimate drivers to gain kernel access and interfere with security products.

The Evolution of Ransomware: From 1989 Floppy Disks to Multi-Million Dollar Extortion Empires

Ransomware has transformed dramatically since its origins in 1989, when evolutionary biologist Joseph Popp mailed AIDS-themed floppy disks demanding $189 via Panamanian mail. Early experiments like GPCode and Archiveus introduced stronger cryptography by the mid-2000s, while Reveton and CryptoLocker in 2012-2013 combined psychological pressure, Gameover Zeus botnets, and Bitcoin payments. Major incidents such as WannaCry, NotPetya, and attacks on Colonial Pipeline and JBS Foods demonstrated global reach and state-level involvement. Modern groups like REvil, LockBit, Maze, and Akira refined double extortion, Ransomware-as-a-Service models, access brokers, and virtualization targeting. Law enforcement operations have disrupted infrastructure repeatedly, yet the market fragments and regenerates with new brands. The core business model remains resilient due to easy initial access, layered extortion tactics, and victims' operational dependencies.

Ragnarök: F6 Investigates VantaCore Ransomware Attacks and Suspected Thor Rebrand

F6's Digital Forensics Laboratory has identified a new ransomware group called VantaCore that has struck at least seven Russian organizations with multimillion-dollar ransom demands. Researchers assess VantaCore as a rebrand of the previously known pro-Ukrainian Thor group, part of a broader consolidation among such actors in 2025–2026. The group abandoned LockBit 3 Black and Babuk in favor of its own VantaCore ransomware built on similar foundations, while deploying custom tools including VantaCoreLoader, VantaCoreRAT, and the SnowKiller BYOVD utility. VantaCore maintains a Tor-based data leak site launched no later than June 2026 and uses double and triple extortion tactics, selling or publicly releasing stolen data after encryption. Initial access relies on exposed RDP, VPN, public application vulnerabilities, and compromised partner credentials, followed by lateral movement via legitimate accounts and SMB/RDP. The group disables security products, clears logs, and destroys backups using Bootice before deploying its ChaCha20/X25519 ransomware via manual RDP sessions or automated loaders.
