Case Study:Managed SOC Ransomware Detection and Response Using XDR & AI

Managed SOC Case Study Ransomware Detection and Response Using XDR & AI

This Managed SOC case study shows how an AI-powered XDR solution detected and stopped a ransomware attack in a hybrid cloud environment. By using SOC automation and a NIST-based response plan, the company reduced its response time (MTTR) by 60%.

The Challenge: Securing Hybrid-Cloud Infrastructure

In 2026, cyber risks increased as businesses used both cloud and on-premise systems. This made security more complex in hybrid cloud environments and harder to manage.

The client was a mid-sized FinTech company. It received many security alerts every day. Many alerts were false, which made it hard to find real threats. Some threats stayed hidden, creating serious risks.

Identity Security: The company used old VPN systems. These were not enough for modern security. It required a Zero Trust (ZTNA) approach, where every user and device are verified before access is granted.

Visibility: The company could not see all systems clearly. This included AWS and on-premise setups. There were many blind spots. Attackers could operate without being noticed.

Old Systems: Some systems used outdated PowerShell. These systems were not updated. They had known weaknesses. Attackers could easily exploit them.

Compliance: The company needed proper logs to meet DORA and PCI-DSS 4.0 rules. But the logs were not complete, so audits were difficult.

Overall, the company required a stronger security approach. It required to reduce risks, improve visibility, and meet compliance requirements.

Detection Strategy: AI-SIEM for Ransomware Detection

Modern SOC systems focus on how things behave, not just on known threats. This helps detect new and hidden attacks that traditional tools miss.

Trigger: The AI system noticed unusual activity in the network. It identified a “Living off the Land” (LotL) attack, where attackers use trusted tools to stay hidden.

Indicator: PowerShell, which is a normal admin tool, started acting in a strange way. It connected to an unknown IP address, which raised a security alert.

XDR Integration: The system combined data from network traffic and endpoint logs. This helped the managed SOC team quickly confirm a web shell attack in real time and act.

Incident Response Lifecycle (NIST Framework)

The SOC team followed the NIST Incident Response framework to handle the attack in a clear and structured way. This helped them detect, analyse, and stop the threat quickly.

Step 1: Detection

The XDR system detected unusual PowerShell activity on a computer in the finance team. PowerShell is a trusted tool, but its behaviour was not normal in this case. The system noticed:

Unusual commands running on the system
Unexpected connections to an external IP
Activity that did not match normal user behaviour

Because of this, the system flagged the activity as suspicious. Early detection helped the team act before the attack could spread.

Step 2: Analysis & Attribution

After detection, SOC analysts investigated the issue using EDR tools. They checked logs and user activity to understand how the attack started. They found:

A harmful Excel file was opened by the user
The file had a hidden macro that triggered the attack
The macro launched a Cobalt Strike tool used by attackers

The Binary Global team identified this as a phishing attack and mapped it to MITRE ATT&CK technique T1566. This helped to understand the attack method and plan the right response.

Step 3: Threat Isolation

Once the threat was confirmed, the SOAR system took quick action to stop it.

The infected computer was isolated from the network to stop the spread
The user’s active sessions were blocked to prevent further access
The malicious IP address was blocked across the system

These steps helped contain the attack and protect other systems from being affected.

Key Findings: SOC Performance Metrics & ROI & Ransomware Protection

Cybersecurity success depends on how fast a threat is detected and how quickly it is handled. In this case, the SOC team showed strong performance across all key areas.

Main Threat : The attack involved LockBit 4.0 ransomware, which is known for data theft and extortion. It is a serious and advanced threat used by cybercriminals.

MTTD (Mean Time to Detect) : The system quickly found the malicious PowerShell activity. This gave attackers less time to act.

MTTR (Mean Time to Respond) : The system responded automatically. It isolated the infected system and reduced response time.

Containment : The attack was stopped early. It did not spread to other systems. Zero Trust controls ensured that no lateral movement was successful across the network.

Compliance : All actions and logs were recorded. This helped the company meet DORA and PCI-DSS 4.0 rules.

Cost Savings : The company avoided paying ransom. It also reduced recovery time and losses.

Overall, the Managed SOC monitoring services helped protect the business, reduce risk, and save costs.

Why Continuous SOC Monitoring Matters

Traditional security tools act after an attack happens. This can delay response and increase damage. It also makes it harder to control the situation quickly.

Binary Global’s Managed SOC team helped detect and stop threats early. Our team monitored systems 24/7 and responded in real time. This reduced risks and prevented attacks from spreading.

Zero Trust: Every user, device, and access request is checked before access is given. This helps block unauthorized users and keeps systems safe.

Lower Costs: Strong security reduces the chances of major attacks. This lowers recovery costs, reduces downtime, and can also lower cyber insurance costs.

Brand Trust: Continuous monitoring helps avoid service outages. It protects customer data and ensures systems run smoothly, which builds customer trust.
