Ukrainian Developer of LockerGoga, MegaCortex and Nefilim Ransomware Sentenced to 12 Years and Nine Months
A 52-year-old Ukrainian national has been sentenced by the Zurich District Court to 12 years and nine months in prison for developing ransomware used in targeted attacks against multiple companies.
The court established that the man was the lead developer of the LockerGoga, MegaCortex and Nefilim encryption tools, although he was not the organizer of the criminal groups that deployed them. The malware was used against organizations in dozens of countries, with total damages from the examined incidents estimated at roughly 100 million Swiss francs.
One of the most prominent victims was Swiss train manufacturer Stadler Rail. In 2020 attackers stole approximately 500 GB of confidential data and demanded $6 million. The company refused to pay. Other affected entities included climate equipment supplier Meier Tobler and banking software developer Crealogix.
The defendant maintained that he had been engaged in ordinary information-security consulting and did not know how his code would be used. However, investigators recovered ransom-demand templates together with the malware source code, which the court found highly incriminating.
The man has been held in pre-trial detention since October 2021. His arrest formed part of a broader international investigation into ransomware operations that struck more than 1,800 citizens and organizations across 71 countries. After serving his sentence he will be prohibited from entering Switzerland for ten years. The verdict is not yet final and may be appealed.

Russian Ransomware Groups INC and The Gentlemen Deploy AI-Driven Phantom Framework for Fully Automated Attacks
SOCRadar researchers have disclosed the Phantom framework, an AI-powered autonomous ransomware attack platform operated by members linked to the INC and The Gentlemen groups. The system uses commercial large language models routed through OpenRouter to scan 7,158 edge devices, steal 535 administrator accounts, and compromise 4,140 endpoints. AI agents autonomously generate custom encryption binaries, craft personalized ransom demands based on stolen financial data, and write kernel drivers to disable EDR solutions before encryption. The framework runs on 32 custom MCP servers that give the AI direct access to scanning, credential abuse, financial analysis, and anti-detection tooling. Human operators only supply target prompts and approve final actions while the AI executes the entire kill chain. Phantom Agent v3.1 implants masquerade as Windows Update components and communicate over encrypted channels with randomized polling intervals. The discovery reveals a mature Ransomware-as-a-Service model that lowers the barrier for other criminal groups to conduct large-scale AI-automated extortion.
Creator of Ransomware Forum Ramp4u Hands Over 1.5 Billion Rubles to Russian Law Enforcement
A darknet researcher known as exkgb has published an analysis of the ransomware forum Ramp4u.io, revealing that its founder cooperated with authorities by transferring 1.5 billion rubles. The report follows the author's earlier coverage of the Exploit forum administration, which drew significant reader interest with only a 6% bounce rate. Ramp4u is described as a dedicated ransomware marketplace operating on the dark web. The article positions the forum as a key platform in the ransomware ecosystem and notes the unusual cooperation with security forces. exkgb continues to monitor and document major darknet platforms for the cybersecurity community.
Ransomware Attack on SoftBank's IDCF Cloud Encrypts 3.6PB in 7 Minutes as Operations Team Misses Alerts for 7 Hours
SoftBank subsidiary IDC Frontier suffered a ransomware attack on its IDCF Cloud East Japan Region 1 that encrypted 3.6PB of primary storage across 239 hypervisors and 225 datastores in just seven minutes. Attackers also destroyed 554,153 snapshots, eliminating 41.5PB of backup capacity and leaving 495 enterprise and government customers without recoverable data from the provider. Operations staff spent the next seven hours repeatedly rebooting already-encrypted virtual machines and resetting console passwords while failing to locate any of the 225 RECOVER-INFO.txt ransom notes left in datastore root directories. The intrusion was only confirmed after the threat actors directly defaced the vCenter management console with the message “IDCF CLOUD INFRASTRUCTURE SEIZED”. The incident highlights critical gaps in asset inventory, log monitoring, and incident response procedures rather than any zero-day exploit. No ransom was paid; the provider instead focused on public updates while advising customers to rely on their own off-site backups.
WannaCry Ransomware: How EternalBlue Turned One Infection Into a Global Epidemic
On 12 May 2017, the WannaCry ransomware worm rapidly infected more than 230,000 computers across at least 150 countries by exploiting the unpatched SMBv1 vulnerability with the EternalBlue exploit. The malware combined remote code execution via EternalBlue with file encryption and ransom demands in Bitcoin, affecting hospitals, manufacturers, and government organizations worldwide. Microsoft had released the MS17-010 patch two months earlier, yet many systems remained vulnerable due to delayed deployment in large environments. WannaCry scanned both local subnets and random public IPv4 addresses in parallel threads, allowing infected machines to autonomously discover and compromise new targets without user interaction. Security researcher Marcus Hutchins halted the initial wave by registering a hardcoded kill-switch domain, though later variants removed this check. The incident demonstrated how a known, patchable flaw combined with worm-like propagation could produce worldwide operational disruption.
