Leveraging ANY.RUN Threat Intelligence data from the past 30 days, an in-depth analysis reveals threat actors using multiple domains to orchestrate ClickFix social engineering attacks, distributing associated malware. The JSON threat intelligence data was converted to CSV format for ingestion into Azure Data Explorer (ADX), enabling advanced querying and correlation of indicators.

Key Findings:

  • Multiple domains used in ClickFix attacks
  • Malware variants deployed from these domains
  • Enhanced visibility into adversarial infrastructure

You Should Know:

1. Extracting & Analyzing Threat Intelligence Data

To replicate this analysis, follow these steps:

Convert JSON to CSV (Python)

import json 
import csv

with open('threat_intel.json', 'r') as f: 
data = json.load(f)

with open('threat_intel.csv', 'w', newline='') as f: 
writer = csv.writer(f) 
writer.writerow(data[bash].keys())  Header 
for entry in data: 
writer.writerow(entry.values())

ADX Query for ClickFix Domains

ThreatIntelligence 
| where DomainName matches regex @"clickfix..(com|net|org)" 
| summarize MalwareCount=count() by DomainName, MalwareType 
| sort by MalwareCount desc

2. Detecting Malware in Your Network

Use these PowerShell & Linux commands to check for malicious activity:

Windows (PowerShell)

Get-NetTCPConnection | Where-Object {$<em>.RemoteAddress -match "malicious-domain.com"} 
Get-Process | Where-Object { $</em>.Path -like "clickfix" } | Stop-Process -Force

Linux (Bash)

netstat -tulnp | grep "malicious-domain.com" 
lsof -i | grep "clickfix" 
ps aux | grep -i "suspicious_process" | awk '{print $2}' | xargs kill -9

3. Blocking Malicious Domains via Firewall

Windows (Firewall Rule)

New-NetFirewallRule -DisplayName "Block ClickFix Domains" -Direction Outbound -Action Block -RemoteAddress "malicious-domain.com"

Linux (iptables)

sudo iptables -A OUTPUT -d malicious-domain.com -j DROP

What Undercode Say

The ClickFix attack demonstrates how threat actors exploit social engineering to distribute malware. By converting threat intelligence into structured formats (CSV) and analyzing it in ADX, defenders gain actionable insights into adversary infrastructure. Proactive measures like firewall rules, process monitoring, and network analysis help mitigate risks.

Prediction

As ClickFix attacks evolve, we may see:

  • More obfuscated domains (e.g., typosquatting)
  • Increased use of fileless malware
  • AI-driven phishing lures

Expected Output:

  • Domains & malware variants list
  • ADX queries for threat hunting
  • Defensive PowerShell/Linux commands
