Crypto-assets are stored in wallets. You can either manage your own wallets or use a service provider like GOin.
Risks
The crypto-assets in your wallets are exposed to various risks, the main ones being:
-
Phishing attacks
Hackers can send emails, SMS or messages on social networks that appear to come from a legitimate source, such as a crypto-asset exchange platform or a wallet service provider. These messages encourage users to click on a malicious link or provide their login information.
-
Brute force attacks
Hackers can try to guess your password or passphrase using brute force software. This is especially risky if you use a weak or easy-to-guess password.
-
Keylogger attacks
A keylogger is a type of malware that records all the keystrokes you type on your keyboard. This can include your passwords, passphrases, and other sensitive information.
-
Code injection attacks
Hackers can inject malicious code into a website or application that you use to access your wallet. This code can allow them to steal your funds or take control of your wallet.
-
Software vulnerability attacks
Wallet software may contain vulnerabilities that can be exploited by hackers. It is important to keep your wallet software up to date with the latest security patches.
-
Human errors
Human errors, such as losing your passphrase or sending funds to the wrong address, can also lead to the loss of your funds.
Advices
-
Choose secure wallets for your personal management
- Hardware wallets. Store your private keys offline, making them inaccessible to hackers. They are recommended for long-term storage of your crypto-assets or if their value is significant. The most well-known are Ledger* and Trezor*.
- Paper wallets. Print your private keys on paper and keep them in a secure place, such as a safe. If a malicious person recovers this paper wallet, they will have instant access to your crypto-assets.
- Software wallets. Choose a reputable wallet with advanced security features. When the value of your crypto-assets is significant, we recommend using this type of wallet only in addition to a hardware wallet to store the crypto-assets needed for your daily transactions. The most well-known are Metamask* and Trust Wallet*.
-
Use a strong and unique password
Your password should be at least 16 characters long and a combination of uppercase and lowercase letters, numbers, and symbols. Do not use the same password for other online accounts.
-
Enable two-factor authentication (2FA)
2FA adds an extra layer of security by requiring you to provide an additional code besides your password when logging in.
-
Be careful with links and websites
Never click on a link in an unsolicited email or message, even if it appears to come from a legitimate source. Always check the URL of the website before entering your information.
-
Keep your software up to date
Install the latest security patches as soon as they are available.
-
Back up your passphrase
Your passphrase is the key to your wallet. It is important to store it in a safe and offline place. Never share it with anyone.
-
Be aware of scams
There are many scams related to crypto-assets. Be wary of offers that seem too good to be true (e.g. a message offering to multiply your crypto-assets by sending them to a specific wallet).
-
Diversify
Do not put all your crypto-assets in the same wallet. This limits the impact in case of theft or loss of one of your wallets.
-
Engage a qualified service provider
You can delegate the custody of your crypto-assets to a service provider like GOin, which, as part of its custody services, implements a set of procedures and policies to manage those risks.
