Data Exfiltration Blocking in a Ransomware Attack with eScan EDR

Introduction

Protect Your Data From Ransomware – It is imperative for businesses today. These days, cybercriminals don’t only
encrypt files, but steal data prior to starting the attack. This is known as data exfiltration, and
it’s hitting epidemic levels.

Now the question is, how do you prevent data theft before it gets too late?
eScan Endpoint Detection and Response (EDR) detects, blocks, and prevents data exfiltration before
a ransomware can hold your business to ransom.

So, let us decode this and learn how eScan helps you with data security.

Data Exfiltration Risks

Hackers have evolved. They don’t simply encrypt your files and ask for a ransom; they first exfiltrate the valuable
business data. That means your sensitive data has already fallen into the wrong hands and remains compromised,
even if you restore from backups. That’s a scary thought.

How Do Hackers Get Your Data?

They use a varied method of procedures, including:

• Command and Control (C2) Communication – Where hackers send stolen data back to their own remote servers.
• Insider Threats – Threats in-house where an employee can be untrustworthy or an account gets compromised
  and feeds protected files.
• Phishing & Credential Theft – Email hacks compromise login details and gain unauthorized access.
• Data Transfer Encryption – Criminals can hide stolen data in encrypted traffic, making it difficult to detect.

What Happens When Data Is Stolen?

• The Ransom Demands Go Up – Hackers threaten to publish your data if you don’t pay.
• Regulatory Fines – A data breach can lead to legal trouble and massive fines.
• Damage to Business Reputation – Customer trust is hard to regain.

That’s why preventing data exfiltration is so essential. And that’s where eScan EDR comes to the rescue.

eScan Defense

eScan EDR provides multi-layered protection to block ransomware and prevent data from being stolen. Here’s how it
protects your business:

1. Real-Time Threat Monitoring

eScan performs a continuous scan for suspicious activity, tracking file movements, unusual data transfers, and
unauthorized access attempts to identify threats before they become problems.

• Detects anomalous network behavior
• Identifies unauthorized access to sensitive files
• Detects outbound data exfiltration attempts

2. Data Loss Prevention (DLP)

Business-critical data loss prevention is a key eScan feature ensuring such malicious activities do not occur in
your network. eScan prevents:

• Transferring files without authorization via USB, email, or cloud
• Moving and copying sensitive data outside protected environments

When ransomware attempts to disperse information, eScan captures it live.

3. Network Traffic Analysis

Hackers send stolen data out through networks. eScan’s Network Intrusion Detection (NID) system
monitors and prevents:

• Suspicious outbound connections
• Irregular transmission of data to unknown servers
• Exfiltrated data obfuscated by encrypted malware traffic

In case of suspicious activity, eScan breaks off the connection with the Internet.

4. Detecting Ransomware Based on Behavior

Standard antivirus solutions only detect already-known threats. eScan EDR goes even further with AI-based behavior tracking.
Instead of relying solely on signatures, it identifies:

• Attempts to encrypt data without permission
• Unexpected access of critical files by processes
• Applications initiating mass file transfers without authorization

This prevents ransomware from locking you out of your data or attempting to steal it.

5. Network Security & Endpoint Security & Access Control

Hackers primarily target endpoints (laptops, servers, employee workstations). eScan EDR protects them by:

• Restricting sensitive file access (only authorized personnel can edit/copy data)
• Preventing the use of malicious USB devices that can exfiltrate data
• Blocking unauthorized apps from running on corporate devices

eScan prevents insider threats, leaks, and external breaches by securing endpoints.

6. Zero Trust Security Policy

eScan implements a Zero Trust concept. This means:

• Nobody gets in without clearing a background check
• All file transfers are inspected
• Security checks apply to legitimate users as well

This approach prevents hackers from masquerading as insiders, mitigating data theft risks.

7. Automated Incident Response

Ransomware moves fast. eScan responds rapidly with automated response tactics, including:

• Instant threat isolation – compromised devices are immediately severed from the network
• Automatic rollback of malicious changes – restoring systems without downtime
• Isolating infected files before they cause damage

This ensures that you don’t have to halt your business operations.

Conclusion

Ransomware Data Protection is more than just backups and encryption; it is about preventing data theft
before an attack occurs. Stolen data leads to ransom demands, legal implications, and reputational damage.

When it comes to providing protection against ransomware and preventing data exfiltration, eScan EDR
employs multi-layered security to implement real-time security measures. With capabilities ranging from network
monitoring to endpoint lockdown, eScan is designed to secure your sensitive business information.

Cyber threats are evolving rapidly. With eScan EDR, you can keep your business one step ahead.
