Malware and tooling in Vexy Ransomware hits Mega Velocity
Malware and tooling: Vexy ESXi Locker, Vexy Linux Locker, Vexy Windows Locker, Tor hidden service control panel
Vexy Ransomware, an emerging Rust-based Ransomware-as-a-Service (RaaS) group first observed in September 2026, has claimed the compromise of Mega Velocity (MEGA VELOCITY PVT LTD), a New Delhi-based software publishing and IT services provider. The group claims exfiltration of 46.68 GB of data and has posted the victim on its Tor leak site as part of a double-extortion campaign. Vexy has rapidly accumulated 7-10 published victims across India, the Americas, and multiple sectors since early September 2026, operating a low-barrier affiliate program ($200 BTC invite fee) with cross-platform lockers for Windows, Linux, and ESXi.
How Vexy Ransomware hits Mega Velocity works
Vexy Ransomware emerged in early September 2026 as a new Ransomware-as-a-Service (RaaS) operation, first advertised on dark web cybercrime forums by a threat actor using the handle 'vexys'. The program was published by 'ReHub' with affiliate rules effective September 2, 2026. Vexy targets affiliates with a low $200 one-time Bitcoin entry fee and offer lockers written in Rust for Windows, Linux, and ESXi VMware environments.
The Windows locker uses AES-256 for bulk file encryption with RSA key wrapping, targets local disks and network shares (SMB), terminates specified services and processes (likely database, backup, and email services to unlock files for encryption), wipes free space after encryption, and self-deletes after execution. It also delivers ransom notes via network printers and customizes desktop wallpaper/icons. The Linux locker provides equivalent capabilities including SMB/NFS network share encryption. The ESXi locker performs stealth encryption of VM datastores, terminates VMware services, and clears event logs before self-deletion.
Affiliates access a Tor onion-based control panel featuring build configuration, real-time analytics, client communication/negotiation tools, 24/7 support, and a multilingual interface. Communication is available via qTox. The group maintains a Tor leak site at vaxytsr3chimdz6siwaqi2lvxxwfkxvffkpwyanr2llequ2hkm56jvqd.onion where victim data is published as part of its double-extortion model.
On September 5, 2026, Vexy claimed Mega Velocity (megavelocity.net), a New Delhi-based private technology company incorporated in 2013 providing software development, maintenance, web design, and Internet/hosting services (CIN: U72200DL2013PTC249231; directors: Deepak Kumar Singh and Aartee Aggarwal). The group alleges exfiltration of 46.68 GB of data. The breach was discovered approximately 1 hour and 10 minutes after the claimed attack time. This was Vexy's 6th published victim per the ThreatCluster ransomware leak-site dataset.
Vexy has shown rapid expansion with victims in India (Annapurna Fashion, Palsana Enviro, Mega Velocity), Brazil (Engefitas), Ecuador (McDonald's Ecuador franchise), and the United States (Sancity Soft Touch), spanning manufacturing, hospitality/food service, retail/e-commerce, environmental services, and IT/technology sectors. India is the most targeted country with at least 4 victims. The group's Tor leak site has shown intermittent availability (~50% uptime), consistent with an emerging operation.
Initial access vectors for Vexy intrusions have not been publicly documented as of this analysis. No specific CVEs, phishing campaigns, or vulnerability exploits have been attributed to the group. The Rust codebase aligns with a broader industry trend toward memory-safe, cross-compilable ransomware that resists reverse engineering (paralleling DeadLock, Kyber, and other Rust-based ransomware families). No public decryptor, full reverse-engineering report, YARA rules, Sigma rules, or Snort signatures have been published for Vexy as of September 6, 2026.

Affected products and versions in Vexy Ransomware hits Mega Velocity
- Mega Velocity — Corporate IT Infrastructure
Vulnerable versions: megavelocity.net systems
Remediation for Vexy Ransomware hits Mega Velocity
Immediate actions
- Isolate affected systems from the network to prevent lateral spread
- Identify and block Tor exit nodes and known onion service access at network perimeter
- Scan for Vexy ransomware indicators: service/process termination events, shadow copy deletion, and free space wiping activity
- Preserve forensic data including event logs, memory captures, and encrypted file samples
- Reset all credentials for accounts that may have been compromised
- Engage incident response team for containment and eradication
Workarounds
- Restrict SMB (port 445) and NFS (port 2049) traffic to only necessary systems
- Monitor for wevtutil or equivalent event log clearing commands on critical systems
- Enable verbose process creation logging (Event ID 4688) with command-line auditing
- Deploy PowerShell logging and script block logging across Windows estate
- Restrict printer access for unauthorized network-based print jobs
Longer-term hardening
- Implement behavioral detection rules for Rust-based ransomware patterns including mass file encryption with uncommon extensions
- Deploy EDR with service/process termination monitoring and alerting
- Implement network segmentation to restrict SMB and NFS share access to authorized systems only
- Deploy Tor network detection and alerting at perimeter gateways
- Establish air-gapped backup strategy with immutable storage
- Implement VM-level snapshots and backup verification for ESXi environments
