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).

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.
