Introduction

Exalyze, a powerful threat intelligence tool developed by ExaTrack, has introduced a groundbreaking update to its search engine. This enhancement allows analysts to automatically extract and cross-reference IP addresses, domains, and URLs across malware samples, significantly improving cyber threat intelligence (CTI) workflows. By enabling one-click searches for shared network indicators, security professionals can quickly uncover hidden connections between malicious campaigns.

Learning Objectives

  • Understand how Exalyze’s new search feature enhances threat intelligence gathering.
  • Learn how to leverage IP/domain searches to track C&C servers and malware campaigns.
  • Discover practical techniques for analyzing shared network indicators in malware samples.

You Should Know

1. Searching for Shared C&C Servers in Exalyze

Command/Code Snippet:

exalyze search --ip 46.166.161.93

Step-by-Step Guide:

  1. Navigate to Exalyze.io and log in.
  2. Upload or select a malware sample (e.g., SystemBC sample).

3. Exalyze will automatically extract embedded IPs/domains.

  1. Click the search icon next to an IP (e.g., 46.166.161.93).
  2. Review all samples associated with that IP to identify linked threats.

Why This Matters:

This feature helps analysts track malware infrastructure, revealing if multiple campaigns share the same C&C server.

2. Extracting Domains from Malware Configurations

Command/Code Snippet (YARA Rule):

rule extract_c2_domains { 
strings: 
$c2 = /([a-zA-Z0-9-]+.)+[a-zA-Z]{2,}/ 
condition: 
$c2 
}

Step-by-Step Guide:

  1. Use a sandbox or static analysis tool to extract malware configs.
  2. Apply the YARA rule to identify embedded C2 domains.
  3. Input discovered domains into Exalyze for cross-sample analysis.

Why This Matters:

Automating domain extraction speeds up IoC (Indicator of Compromise) enrichment.

3. Bulk Querying IPs via Exalyze API

Command/Code Snippet (Python):

import requests

api_key = "YOUR_API_KEY" 
ip_list = ["46.166.161.93", "192.168.1.1"]

for ip in ip_list: 
response = requests.get(f"https://api.exalyze.io/v1/search?ip={ip}&key={api_key}") 
print(response.json())

Step-by-Step Guide:

1. Obtain an API key from Exalyze.

  1. Use the script to query multiple IPs programmatically.

3. Analyze results for connections between malware samples.

Why This Matters:

Automating IP lookups allows large-scale threat correlation.

4. Detecting Fast-Flux Domains in Exalyze

Command/Code Snippet (Bash):

whois example.com | grep "Name Server"

Step-by-Step Guide:

1. Identify suspicious domains in Exalyze’s search results.

  1. Run `whois` to check for frequently changing name servers (fast-flux).
  2. Correlate findings with other malware samples in Exalyze.

Why This Matters:

Fast-flux domains often indicate resilient botnet infrastructure.

5. Hardening Cloud Logs Against C2 Communications

Command/Code Snippet (AWS CLI):

aws guardduty create-filter --action ARCHIVE --finding-criteria '{"Criterion": {"service.action.networkConnectionAction.remoteIpDetails.ipAddressV4": {"Eq": ["46.166.161.93"]}}}'

Step-by-Step Guide:

1. Use Exalyze to identify malicious IPs.

  1. Block them in AWS GuardDuty or other cloud security tools.

3. Monitor logs for further communication attempts.

Why This Matters:

Proactively blocking known C2 IPs reduces breach risks.

What Undercode Say

  • Key Takeaway 1: Exalyze’s update transforms manual CTI processes into automated, scalable investigations.
  • Key Takeaway 2: Cross-referencing network indicators exposes hidden relationships between malware families.

Analysis:

Exalyze’s new feature addresses a critical gap in threat intelligence—efficiently linking disparate malware samples via shared infrastructure. By reducing the time needed to pivot on IoCs, security teams can respond faster to emerging threats. Future integrations with SIEMs and EDR platforms could further streamline threat hunting.

Prediction

As cybercriminals increasingly reuse infrastructure, tools like Exalyze will become essential for proactive defense. Expect AI-driven correlation engines to further automate threat detection, making real-time CTI the new standard.
