OPSEC is a systematic process of identifying, analyzing, and protecting sensitive information that could be exploited by adversaries. In the context of crypto, OPSEC is crucial for several reasons:
- Protecting your digital assets: With the increasing value and popularity of cryptocurrencies, cybercriminals are constantly looking for ways to steal digital assets. Implementing robust OPSEC measures can help safeguard your funds from theft and unauthorized access.
- Ensuring privacy: Privacy is a key feature of many cryptocurrencies, and maintaining proper OPSEC can help protect your transactional and personal information from being exposed to malicious actors.
- Preventing targeted attacks: Individuals and organizations with significant cryptocurrency holdings may become targets for phishing, ransomware, and other types of cyber attacks. Strong OPSEC practices can reduce the risk of falling victim to these threats.

A hardware wallet is a physical device that securely stores your private keys offline.

Enable Two-Factor Authentication (2FA)
Enable 2FA on all your accounts, including email, exchanges, and wallets. 2FA requires an additional verification step, such as a code sent to your mobile device, or an app on your phone, making it harder for cybercriminals to gain access to your accounts. Using YubiKey is one of the best and safest 2FA around that adds an extra level of protection. The YubiKey 5 Series is a hardware-based authentication solution that provides superior defense against account takeovers and enables compliance.

Use Unique Email Addresses and Strong and Unique Passwords
Create strong, unique passwords for each of your accounts. Avoid using common words, phrases, or patterns. Instead, use a combination of upper and lowercase letters, numbers, and special characters. Consider using a password manager to generate and store your passwords securely. The password manager I use and recommend is Last Pass. It’s an easy and safe way to store all your passwords. You can also add a level of protection by using a unique email for each account. Protonmail is by far the best email service that I have tried. You can create unique email addresses but they are all sent to the same inbox making it more convenient. It’s Also end-to-end encryption and zero-access encryption to secure your communications.

Beware of Phishing Attacks
Be cautious when clicking on links or downloading attachments from unknown sources. Cybercriminals often use phishing emails and websites to trick users into revealing sensitive information or installing malware. Always verify the legitimacy of the source before proceeding. If you hover over any link in the email with the mouse and it will show you the link connected to it. Make sure it’s the actual link before clicking on it. A lot of business are starting to implement anti-phishing email systems where you choose a personal pin number that will appear on the email so you know it’s from them. So take the time to sign up for that extra level of protection.
