Introduction
In the ever-evolving world of cyber threats, the VanHelsing ransomware group has emerged in 2025 as one of the most aggressive and technically sophisticated adversaries. Within just a few months of surfacing, this group has orchestrated attacks across multiple platforms and geographies, leaving a trail of encrypted systems and exposed data. In response, AttackIQ has built a simulation framework to emulate VanHelsing’s tactics, giving cybersecurity teams a valuable tool to prepare for and defend against this evolving threat.
VanHelsing’s Rapid Rise and AttackIQ’s Tactical Emulation
Launched in March 2025, VanHelsing quickly gained infamy for its Ransomware-as-a-Service (RaaS) model. It targets a broad range of systems including Windows, Linux, BSD, ARM-based devices, and VMware ESXi, demonstrating a rare versatility in ransomware operations. The malware’s Windows variant is particularly dangerous, developed in C++ and secured with advanced cryptographic schemes like Curve25519 and ChaCha20. It also brands its attacks by appending “.vanhelsing” to encrypted files.
VanHelsing uses a double-extortion tactic. It steals data before encrypting it, then threatens to leak that data unless a ransom is paid. So far, five confirmed victims have been identified in the US, France, Italy, and Australia. For three of them, stolen data has already been posted publicly.
The group’s affiliate program is designed like a startup business: a \$5,000 deposit grants access to a portal where partners manage victims and payments, keeping 80% of ransom profits. This streamlined backend further accelerates the spread and complexity of attacks.
To counter this rising threat, AttackIQ has developed a comprehensive attack graph based on behavioral insights from CheckPoint’s March 23, 2025 report. The simulation mimics VanHelsing’s tactics, from initial breach and reconnaissance to file encryption and lateral movement, giving organizations a powerful new way to test their defenses.
The ransomware’s methods include using Windows API calls to avoid detection, such as IsDebuggerPresent, and locale checks to avoid targeting unintended victims. For system profiling, it uses GetEnvironmentStrings and GetNativeSystemInfo, and it deletes Volume Shadow Copies to block data recovery using commands like wmic shadowcopy delete.
Later stages involve scanning for network shares and executing payloads using CreateProcessA, eventually encrypting files with proprietary cryptographic tools. The goal is to paralyze operations and increase pressure on victims to pay.
AttackIQ’s simulation doesn’t just replicate these tactics; it lets organizations stress-test their security controls. It identifies critical intervention points, such as blocking initial tool ingress and monitoring shadow copy deletions. These strategies align with the MITRE ATT\&CK framework and support broader recommendations around intrusion prevention, robust backups, and access management.
By using this emulation platform, companies can proactively adapt their defenses and validate readiness against one of today’s most advanced threats.
What Undercode Say:
VanHelsing’s emergence as a multi-platform ransomware powerhouse is not just a warning sign but a turning point in how threats are developing in 2025. This group represents the new generation of threat actors — highly organized, financially motivated, and tech-savvy enough to bypass traditional defenses with ease.
What makes VanHelsing especially dangerous is its seamless integration of advanced cryptography, anti-analysis techniques, and aggressive affiliate expansion. Unlike amateur ransomware groups of the past, this one operates like a decentralized tech firm, complete with a user-friendly backend for partners, profit sharing models, and targeted regional avoidance mechanisms. These are not just hackers — they are entrepreneurs of chaos.
AttackIQ’s simulation is an essential step in flipping the script. It empowers defenders to move from reactive defense to proactive validation. By mapping each stage of the VanHelsing kill chain, security teams gain the insight needed to detect early indicators and implement hardening strategies in time. For example, the deletion of shadow copies is a red flag that should immediately trigger alerts and backup enforcement protocols.
Equally concerning is VanHelsing’s focus on cross-platform capability. Many organizations still maintain a patchwork of operating systems — Windows servers alongside Linux machines, with legacy BSD boxes and cloud-based ARM architectures. VanHelsing’s ability to compromise this diversity increases the overall blast radius, especially in hybrid infrastructure setups.
The affiliate model cannot be overlooked either. It lowers the bar for cybercriminal entry, enabling lesser-skilled actors to launch full-scale ransomware operations using rented tools. The low-cost, high-reward model is attracting a surge of new players to the cybercrime arena.
AttackIQ’s work, aligned with MITRE ATT\&CK and supported by real-world telemetry, allows defenders to test their detection logic against actual TTPs. The takeaway here is simple: emulate what adversaries do, not what we think they do. That distinction is what transforms threat intelligence into operational resilience.
For any organization serious about cyber defense, integrating attack simulations like this isn’t optional anymore. It’s a necessity. Continuous validation, red-teaming, and automated security assessments must now become part of the standard cybersecurity playbook. If the attackers are evolving daily, so should the defenders.
VanHelsing is only the beginning. Its success will inspire clones and competitors. The security industry must recognize this moment as a call to arms — not for fear, but for preparation. And tools like AttackIQ’s simulation platform could be the difference between recovery and ruin.

Prediction
Given its advanced capabilities and business-savvy RaaS model, VanHelsing is likely to expand its reach and sophistication over the next 6–12 months. More affiliates will join, driven by high rewards and low entry barriers. Expect new variants targeting mobile devices and cloud-native environments, along with potential integrations of AI-driven evasion techniques. Organizations must prioritize threat emulation and behavioral defense if they hope to keep up.
