CVE-2025-5086 (Dassault DELMIA Apriso Deserialization Flaw) — Targeted by Ransomware Operators

 


Executive Summary

CyberDudeBivash Threat Intel is monitoring CVE-2025-5086, a critical deserialization of untrusted data vulnerability in Dassault Systèmes DELMIA Apriso (2020–2025). Rated CVSS 9.0 (Critical), this flaw allows remote code execution (RCE) under certain conditions.

 The vulnerability is already included in CISA’s Known Exploited Vulnerabilities (KEV) Catalog, with reports of ransomware affiliates exploiting it to deploy payloads in industrial control and manufacturing environments.

Background: Why DELMIA Apriso Matters

Dassault DELMIA Apriso is a manufacturing operations management (MOM) platform used globally in:

  • Industrial control systems (ICS)

  • Smart factories & supply chains

  • Manufacturing Execution Systems (MES)

Because of its position in production and logistics workflows, compromise of Apriso can lead to:

  • Disruption of production lines

  • Data exfiltration of intellectual property (IP)

  • Ransomware-enforced downtime

Vulnerability Overview

  • CVE ID: CVE-2025-5086

  • Component: Apriso deserialization engine

  • Type: Deserialization of untrusted data

  • Impact: Remote Code Execution (RCE)

  • Severity: CVSS v3.1 = 9.0 (Critical)

  • Exploit status: Actively exploited, listed in CISA KEV Catalog

Exploitation by Ransomware Operators

Threat intel sources indicate ransomware groups are:

  1. Scanning exposed Apriso endpoints.

  2. Injecting crafted serialized payloads to gain execution.

  3. Deploying persistence & lateral movement tools.

  4. Exfiltrating sensitive production data before encryption.

 This aligns with double extortion tactics (encrypt + leak).

CVSS Breakdown

  • Attack Vector (AV): Network

  • Attack Complexity (AC): Low

  • Privileges Required (PR): None (remote unauthenticated possible)

  • User Interaction (UI): None

  • Confidentiality Impact (C): High

  • Integrity Impact (I): High

  • Availability Impact (A): High

Final Score: 9.0 (Critical)

Defensive Strategies

1. Apply Vendor Patches

  • Dassault Systèmes has released security updates.

  • Organizations must upgrade Apriso instances immediately.

2. Network Hardening

  • Do not expose Apriso endpoints directly to the Internet.

  • Place Apriso behind VPN or Zero Trust gateways.

  • Restrict access to known corporate IPs.

3. Monitor Indicators of Compromise (IoCs)

  • Look for anomalous serialized payloads in network logs.

  • Watch for unexpected process creation on Apriso servers.

  • Monitor C2 traffic patterns associated with ransomware families.

4. Backup & Resilience

  • Maintain offline immutable backups.

  • Test disaster recovery playbooks regularly.

SOC Hunting & Detection

  • SIEM rule: Alert on unexpected execution in Apriso processes.

  • EDR/XDR: Monitor for privilege escalation attempts via deserialization chains.

  • Threat intel feeds: Subscribe to CyberDudeBivash Threat Intel updates for IoCs.

CyberDudeBivash Recommendations

  • Treat CVE-2025-5086 as urgent, patch immediately.

  • Monitor for ransomware activity targeting Apriso.

  • Integrate Zero Trust, MFA, and network segmentation.

  • Use CyberDudeBivash defense playbooks for incident response.

Gentlemen Ransomware: SMB Phishing, Advanced Evasion, and Global Impact — CyberDudeBivash Threat Analysis

  Executive Summary The Gentlemen Ransomware group has quickly evolved into one of the most dangerous cybercrime collectives in 2025. First spotted in August 2025 , the group has targeted victims across 17+ countries with a strong focus on SMBs (small- and medium-sized businesses) . Their attack chain starts with phishing lures and ends with full-scale ransomware deployment that cripples organizations. CyberDudeBivash assesses that Gentlemen Ransomware’s tactics—including the abuse of signed drivers, PsExec-based lateral movement, and domain admin escalation —make it a critical threat for SMBs that often lack robust cyber defenses. Attack Lifecycle 1. Initial Access via Phishing Crafted phishing emails impersonating vendors, payroll systems, and invoice alerts. Credential harvesting via fake Microsoft 365 login pages . Exploitation of exposed services with weak authentication. 2. Reconnaissance & Scanning Use of Advanced IP Scanner to map networks. ...
