Ransomware Alert: RADIX Falls Victim to Sarcoma Group 🛡️
In a new development on the cybercrime front, the notorious Sarcoma ransomware group has reportedly compromised RADIX, a digital infrastructure service provider, adding them to their list of victims. The breach was reported by ThreatMon, a threat intelligence platform, via their Ransomware Monitoring service on June 19, 2025, at 05:15 UTC+3.
Shared through a brief but impactful social media update, ThreatMon revealed that the Sarcoma group had updated its victim roster on dark web leak sites — an act that typically follows a successful encryption and data exfiltration attack. This inclusion signals that RADIX may be under pressure to pay a ransom or face public data exposure.
The incident is part of a larger trend observed across the cybersecurity landscape, where advanced ransomware operators are targeting infrastructure companies, cloud services, and critical SaaS vendors. Sarcoma, while not as widely known as other groups like LockBit or BlackCat, has been steadily increasing its footprint in 2025.
What Undercode Say: Deconstructing the RADIX Ransomware Hit 🔍
Who Is Sarcoma?
Sarcoma is a relatively new but dangerous ransomware group active in 2024–2025, with behavior patterns mimicking professional threat actor syndicates. Known for its stealthy infiltration methods and data-leak extortion tactics, Sarcoma prefers to target organizations with weak segmentation, poor endpoint security, and unpatched software.
Their modus operandi often includes double extortion — encrypting systems and threatening to leak stolen data unless ransom demands are met.
Why RADIX?
RADIX is known for offering infrastructure and cloud services, potentially making it a high-value target for threat actors looking to cause broad disruption. Such companies often manage networks or data for third-party clients, so breaching them means access to a wider digital ecosystem.
Sarcoma’s interest in RADIX likely stems from:
A possible vulnerability in
Inadequate endpoint detection or response systems.
High-value datasets housed within the RADIX infrastructure.
The Cyber Kill Chain: Possible Phases
- Reconnaissance – Gathering intel about RADIX infrastructure via OSINT or phishing campaigns.
- Weaponization – Delivering payload via malicious email or vulnerable port exploit.
- Delivery & Exploitation – Possibly via remote desktop protocol (RDP) or exposed APIs.
4. Installation – Installing ransomware binaries silently.
- Command and Control (C2) – Exfiltrating data and maintaining remote access.
- Actions on Objectives – Encryption and data exfiltration with a threat of public exposure.
Implications of the Breach
Business Interruption: RADIX’s clients may experience service outages or data unavailability.
Reputational Damage: Trust erosion among enterprise partners and potential customer churn.
Compliance Risks: Possible violations of GDPR or other data protection frameworks.
Broader Trend in 2025
Ransomware attacks have shown a marked increase in targeting infrastructure-as-a-service (IaaS) providers. These companies host environments for other businesses, making them ideal attack vectors for cascading impact.
Threat actors are leveraging:
AI-driven malware variants.
Zero-day exploits in widely-used platforms.
Blockchain-based communication channels for anonymity.
Sarcoma’s activity is a wake-up call for infrastructure service providers to review their cyber posture, adopt zero-trust principles, and enforce strict access controls.
✅ Fact Checker Results
Sarcoma’s activity on the dark web is confirmed by ThreatMon’s threat intelligence data.
RADIX’s inclusion as a victim aligns with known Sarcoma group tactics.
Ransomware patterns match the double extortion methods typical of advanced threat groups.
🔮 Prediction
Based on current ransomware activity and cyber threat intelligence trends, it is highly likely that Sarcoma — and similar groups — will continue targeting cloud infrastructure and SaaS companies through supply-chain attacks and third-party service vulnerabilities.
Organizations like RADIX must prioritize:
Advanced threat detection systems
Real-time monitoring
Data backup strategies
to stay ahead of these evolving digital threats.
