1. Introduction

This document serves as a personal threat model focused on cybersecurity in the area of cryptocurrencies. Its aim is to identify potential threats and vulnerabilities and propose measures to minimize them.

2. Identification of Actors and Assets

Actors

  • Hackers
  • Regulatory Bodies
  • Competitors
  • Close Associates

Assets

  • Crypto Wallet
  • Transaction History
  • Investment Strategy

Actors and Assets: Detailed View

In this part of the threat model, it is crucial to identify in detail the actors who could pose a threat and the assets they might want to compromise. Each actor and asset should be elaborated on, including motivations, capabilities, and methods of attack.

Hackers

  • Motivation: Financial gain, reputational reasons, ideological beliefs
  • Capabilities: Malware, ransomware, phishing attacks
  • Attack Methods: Wallet infiltration, keylogging, SIM swapping

Regulatory Bodies

  • Motivation: Oversight and regulation, ensuring compliance with laws
  • Capabilities: Legal measures, access to public and private databases
  • Attack Methods: Court orders, asset seizure, audits

Competitors

  • Motivation: Gaining competitive advantage, financial gain
  • Capabilities: Industrial espionage, social engineering
  • Attack Methods: Infiltration, misinformation, market manipulation

Close Associates

  • Motivation: Personal interests, possible financial gain
  • Capabilities: Access to personal devices, knowledge of personal information
  • Attack Methods: Using known passwords, accessing unsecured devices

Assets

Crypto Wallet

  • Importance: High
  • Attack Types: Phishing, malware, physical access
  • Mitigations: Hardware wallet, 2FA, strong passwords

Transaction History

  • Importance: Medium
  • Attack Types: IP tracking, exchange compromise
  • Mitigations: Use of VPN, decentralized exchanges

Investment Strategy

  • Importance: Medium to High
  • Attack Types: Social engineering, industrial espionage
  • Mitigations: Limiting information sharing, using encrypted communication

3. Vulnerabilities

Using Online Wallets with Low Security

  • Description: Online wallets are often targeted by attacks, especially if not properly secured.
  • Actors: Hackers, competitors
  • Attack Types: Phishing, brute-force attacks
  • Mitigations: Switching to a hardware wallet, using 2FA

Unsecured Wi-Fi Network

  • Description: Using unsecured Wi-Fi networks can allow attackers easy access to your data.

Insufficient Two-Factor Authentication (2FA)

  • Description: Absence or poor implementation of 2FA can lead to easy access to sensitive data.
  • Actors: Hackers, close associates
  • Attack Types: Brute-force attacks, SIM swapping
  • Mitigations: Activation and proper configuration of 2FA

Insufficient OPSEC (Operational Security)

  • Description: Insufficient OPSEC may include poor handling of passwords, keys, and other sensitive data.
  • Actors: All
  • Attack Types: Social engineering, phishing
  • Mitigations: Cybersecurity education, use of a password manager

4. Attack Vectors

Phishing Attacks

  • Description: Attacks that aim to obtain sensitive information through fraudulent emails or websites.
  • Actors: Hackers, competitors
  • Vulnerabilities: Insufficient OPSEC, using online wallets with low security
  • Mitigations: Cybersecurity education, use of 2FA

Man-in-the-Middle Attacks

  • Description: Attacks where the attacker eavesdrops on or manipulates communication between two parties.
  • Actors: Hackers, regulatory bodies
  • Vulnerabilities: Unsecured Wi-Fi network, outdated software
  • Mitigations: Use of VPN, encryption of communication

Social Engineering

  • Description: Manipulating people to obtain sensitive information or system access.
  • Actors: Competitors, close associates
  • Vulnerabilities: Insufficient OPSEC, insufficient 2FA
  • Mitigations: Cybersecurity education, limiting information sharing

SIM Swapping

  • Description: An attack in which the attacker gains control of the target’s SIM card.
  • Actors: Hackers
  • Vulnerabilities: Insufficient 2FA, insufficient OPSEC
  • Mitigations: Use of hardware-based 2FA, high level of OPSEC

5. Measures

Using a Hardware Wallet

  • Description: Hardware wallets provide a high level of security for storing cryptocurrencies.
  • Actors: Hackers
  • Suitable for: Protecting the crypto wallet
  • How to Implement: Purchase a reputable hardware wallet such as Ledger or Trezor and transfer your cryptocurrencies to it.

Using a VPN

  • Description: A VPN provides anonymity and security when browsing the internet.
  • Actors: Regulatory bodies, hackers
  • Suitable for: Protecting transaction history, securing Wi-Fi
  • How to Implement: Choose a trusted VPN provider and enable it when connecting to the internet.

Activation and Proper Configuration of 2FA

  • Description: Two-factor authentication adds an additional layer of security.
  • Actors: Hackers, close associates
  • Suitable for: Protecting the crypto wallet, securing online accounts
  • How to Implement: Enable 2FA on all important accounts and use an app like Google Authenticator or a hardware key like YubiKey.

Cybersecurity Education
