Analyzing Ransomware Payment Wallets

Overview

Cybersecurity skill for analyzing ransomware payment wallets. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "analyzing ransomware payment wallets"

• "Traces ransomware cryptocurrency payment flows using blockchain analysis tools s"

• An organization has been hit by ransomware and the ransom note contains a Bitcoin or cryptocurrency wallet address that needs investigation

• Law enforcement or incident responders need to trace where ransom payments flowed after the victim paid

• Threat intelligence analysts are attributing ransomware campaigns by clustering payment infrastructure across incidents

• Investigators need to determine if a ransomware group is reusing wallet infrastructure across multiple victims

• Compliance or legal teams need evidence of fund flows for prosecution, sanctions enforcement, or insurance claims

Do not use this skill for live payment interception or to interact directly with ransomware operators. All analysis should be passive and read-only against public blockchain data.

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Python 3.8+ with requests, json, and hashlib libraries
• Access to blockchain explorer APIs (blockchain.com, WalletExplorer.com, Blockstream.info)
• Familiarity with Bitcoin transaction model (UTXOs, inputs, outputs, change addresses)
• Understanding of common obfuscation techniques (mixers, tumblers, peel chains, cross-chain swaps)
• Optional: Chainalysis Reactor license for enterprise-grade cluster analysis
• Optional: OXT.me for advanced transaction graph visualization

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    : ,
}

 () -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
