Analyst: Security Arsenal Intel Unit
Threat Actor Profile — DRAGONFORCE
DRAGONFORCE operates as a aggressive Ransomware-as-a-Service (RaaS) entity, recently observed pivoting from strictly industrial targets to a broader "spray and pray" approach affecting professional services and healthcare.
- Aliases: DragonForce (no confirmed rebrands yet, but tactics mirror defunct Twisted Spider operations).
- Model: RaaS with affiliate network. Affiliates handle initial access; core team develops encryption.
- Ransom Demands: $500,000 to $5,000,000 USD, typically demanding 10-20% of annual revenue based on stolen financials.
- Initial Access: Heavily reliant on external remote services. Dominant vectors include ConnectWise ScreenConnect exploitation, Microsoft Exchange vulnerabilities, and unsecured RDP/VPN endpoints.
- Extortion Strategy: Double extortion. Victims are posted to the leak site immediately after the timer expires (usually 3-5 days).
- Dwell Time: Short (average 3-7 days). The group moves rapidly from initial access to exfiltration to encryption.
Current Campaign Analysis
DRAGONFORCE executed a significant mass-posting event on 2026-05-27, listing 15 victims across diverse geographies. This indicates a high-volume exploitation phase, likely leveraging the ConnectWise ScreenConnect (CVE-2024-1708) vulnerability which surged in exploitation following its CISA KEV addition in April.
Targeted Sectors
The attack footprint has broadened from traditional manufacturing to:
- Transportation & Logistics: High-value targets (e.g., President Container Group).
- Technology: Software and IT services (e.g., Northbridge, Nemd).
- Agriculture/Food: Critical infrastructure disruption (e.g., Dunasgroen, Pieralisi).
- Healthcare: Ramos Rheumatology (US).
Geographic Concentration
- Primary: United Kingdom (GB), Canada (CA), Netherlands (NL).
- Secondary: United States (US), Singapore (SG), Italy (IT), Germany (DE).
Victim Profile
- Size: Mid-Market to Upper-Mid-Market ($50M - $1B revenue).
- Infrastructure: Heavy reliance on on-premise Exchange servers and remote access tools (ScreenConnect) is evident based on the exploited CVEs.
Observed Patterns & CVE Connection
The rapid-fire posting of 15 victims in 24 hours suggests automated deployment following successful exploitation of:
- CVE-2024-1708 (ConnectWise ScreenConnect): Likely entry point for Technology and Business Services victims.
- CVE-2025-52691 / CVE-2026-23760 (SmarterTools SmarterMail): Probable vector for the Consumer Services and Ag/Food sectors running mail gateways.
- CVE-2026-20131 (Cisco Secure Firewall): Potential bypass for network perimeter controls in larger logistics entities.

Incident Response Priorities
T-Minus Detection Checklist (Pre-Encryption)
- Check ScreenConnect Logs: Review
ScreenConnect_<WebSite>_Log.txtfor URI anomalies on 2026-04-28 to present. - Exchange IIS Logs: Hunt for
POSTrequests to/ecp/or/owa/containing deserialization payloads. - MFA Audits: Identify any accounts that recently bypassed MFA or logged in from new geolocations (NE, SG, NL).
Critical Assets for Exfiltration
DRAGONFORCE focuses on data that disrupts operations:
- Logistics manifests and shipment schedules (Transportation sector).
- Source code and IP repositories (Technology sector).
- Patient records (Healthcare).
Containment Actions
- Isolate: Immediately disconnect internet-facing Exchange and ScreenConnect servers from the internal network.
- Disable: Disable local administrator accounts on endpoints.
- Suspend: Suspend integration accounts used for EDI/logistics data transfer.
Hardening Recommendations
Immediate (24 Hours)
- Patch Critical CVEs: Apply patches for CVE-2024-1708 (ScreenConnect) and CVE-2026-23760 (SmarterMail) immediately.
- Block Access: Restrict access to
/Setupand/Loginpaths on ScreenConnect interfaces to known IP ranges via WAF. - MFA Enforcement: Enforce hardware-token based MFA for all remote access (VPN/RDP) and cloud email admin consoles.
Short-Term (2 Weeks)
- Network Segmentation: Move Exchange and Remote Access tools to a dedicated DMZ with strict egress filtering.
- EDR Deployment: Ensure EDR coverage is 100% on critical servers, specifically monitoring for
PsExecandWMIexecution. - Backup Integrity: Perform a restore test of your most recent offline backup.
