Tips to secure crypto-asset wallets

Hackers may send emails, SMS or social media messages that appear to come from a legitimate source, such as a crypto-asset exchange platform or wallet service provider. These messages prompt users to click on a malicious link or provide their login credentials.

Brute force attacks use automated programs to systematically try all possible password combinations until finding the correct one. Weak or commonly used passwords are particularly vulnerable to this type of attack.

A keylogger is malicious software that records all keyboard strokes, including passwords, recovery phrases, and sensitive information. These programs can be installed through malicious downloads or compromised websites.

Hackers can inject malicious code into websites or applications to compromise digital wallets. This code can intercept transactions, modify destination addresses, or steal login credentials.

Security flaws in wallet applications or operating systems can be exploited by hackers to access crypto-assets. It is essential to keep all software up to date with the latest security patches.

Loss of recovery phrases, sending funds to the wrong address, or inadvertently sharing sensitive information are common errors that can lead to irreversible loss of crypto-assets.

**Hardware wallets**: Ledger, Trezor - These physical devices store your private keys offline, offering maximum protection against cyberattacks.

**Paper wallets**: For backup, print your private keys and store them in a safe place. Be cautious of prying eyes during creation.

**Software wallets**: Metamask, Trust Wallet - Use them only for small amounts or frequent transactions, as they are more vulnerable to online attacks.

Create passwords of at least **16 characters** including uppercase, lowercase, numbers, and symbols. Never use the same password for multiple accounts. Consider using a secure password manager to manage your credentials.

Two-factor authentication adds an extra layer of security by requiring a temporary code in addition to your password. Prefer authentication apps (Google Authenticator, Authy) over SMS which can be intercepted.

Systematically install security updates for your operating systems, browsers, and wallet applications. These updates often fix critical vulnerabilities that could be exploited by hackers.

Never click on suspicious links in emails, SMS, or social media messages. Always verify website URLs before logging in. Hackers often create fraudulent sites that look like legitimate platforms.

Don't keep all your crypto-assets in a single wallet. Distribute them across multiple wallets (hardware wallet for long-term storage, software wallet for regular transactions) to limit risks in case of compromise.

For maximum security and regulatory compliance, use a professional custody service provider like GOin, AMF-licensed and ISO 27001:2022 certified. We offer a secure infrastructure with asset segregation, MPC-CMP protocol, and 24/7 continuous monitoring.
