Secure Your Crypto: OPSEC Tips to Protect Your Assets


  • Operational Security (OPSEC) is an essential process for crypto security, especially when it comes to hardware wallets.
  • Attackers are becoming more sophisticated and as such, there’s a higher risk of cryptocurrency hacks.
  • Securing the signing environment is key to protecting yourself against attackers.

What Is OPSEC?

Operational security, or OPSEC, is a risk management process that involves defining what information you are trying to secure and then taking the practical steps required to achieve that goal. The philosophy behind OPSEC focuses on thinking like your attacker and understanding their potential strategies. It’s especially essential for crypto security when it comes to hardware wallets.

Why Is Crypto Security Important?

As digital assets become more mainstream, attackers look for new ways to exploit users and platforms. The stakes and risk profile will vary from entity to entity, but it’s important for all users to observe best practices for protecting their value — especially in light of the record-breaking $3.8 billion in cryptocurrency stolen during 2022.

Secure Your Signing Environment

When signing transactions, look at your environment and identify anything that could serve as an attack vector — this includes cameras or microphones present on modern laptops and mobile devices as well as Internet of Things (IoT) products such as smart TVs or Alexa devices. To maximize security, power down or even remove these devices from the area of operation altogether if necessary. If you must sign transactions from a public space like an office or cafe, take extra precautions by cleaning out any potential attack vectors first.


Performing good operational security measures is critical when dealing with digital assets — particularly with cryptocurrency key-signing devices like hardware wallets where large sums of money are at stake. Understanding your attacker’s strategies and securing your signing environment should be top priorities when handling cryptocurrencies in order to protect yourself against theft or exploitation attempts.
