The cryptocurrency space, while full of opportunities, is not without its dangers. Hackers and imposters are exploiting the anonymity, decentralization, and relative newness of the industry to deploy sophisticated methods of theft. This article explores the main techniques used by these malicious actors and offers practical advice on how to protect yourself from them.

Les Faux Giveaways

Fake giveaways are among the most common scams in the cryptocurrency world. The concept is simple: a hacker pretends to be a celebrity or a well-known company and offers a contest or giveaway promising to double or triple your crypto funds. To participate, you simply send a small amount of money to a given address, with the promise of receiving much more in return. Naturally, the money sent disappears, and you don’t get any feedback.

A fake giveaway can exploit compromised Twitter or YouTube accounts, posting links to perfectly imitable phishing sites. These sites not only collect the funds sent, but can also steal your personal information or private keys.

Fake NFTs and Hidden Malwares

NFTs (Non-Fungible Tokens), while extremely popular, are also used to distribute malware. Some hackers create NFTs that, when purchased or even just viewed, trigger malicious code. This code can empty your wallet or compromise your private keys.

An NFT file may contain a script that, when opened on a platform that supports smart contracts, executes malicious code. For example, this script could add invisible permissions to a smart contract, giving the hacker access to your wallet. An innocent click could cost you dearly.

False Promises of Gains

Scam messages telling you that you’ve “won” a large sum of USDT or another cryptocurrency are common. These messages often redirect you to a site where you’re asked to connect your wallet to “claim” your winnings. But these sites are designed to steal your information or drain your funds.

These scams often use smart contracts that, once allowed to interact with your wallet, can transfer all your assets to the hacker's wallet. A formidable trap and easy to avoid with a little vigilance.

The Imitation Tokens

Creating a token that looks like a popular one but has no real value is another common method. Hackers create these tokens to exchange them for legitimate crypto. These fraudulent tokens sometimes appear in your wallet without you having purchased them, tricking you into exchanging them for valid crypto.

These tokens often mimic the address of a popular token, sometimes changing a single character. If you try to sell or trade them, it can trigger malicious scripts that siphon off your funds. Be careful.

Identity Theft on Telegram

Hackers also use platforms like Telegram to pose as administrators, project team members, or benevolent investors. They offer help or investment advice, but their real intention is to steal your information or funds.

These imposters send links to phishing sites or ask to make a specific transaction that actually transfers your funds to their address. A simple transaction can change everything.

Phishing and Fake Advice

Phishing, a classic hacking technique, has evolved in the cryptocurrency field. Hackers send emails, messages or DMs with links to sites imitating those of well-known exchanges or wallets. Once you enter your information, it is immediately captured by the hacker.

Some phishing sites are so well designed that they almost perfectly copy the interfaces of popular platforms like MetaMask or Binance. Hackers may even use very similar domains to trick users. Don’t be fooled by a familiar interface!

Protecting Yourself from Attacks

• Source Verification: Before entering a giveaway or clicking on a link, always verify the authenticity of the source. Never rely solely on the appearance of an account or site.

• Double Authentication: Use two-factor authentication (2FA) on all your cryptocurrency-related accounts. It’s an extra layer of security that can make all the difference.

• Smart Contract Analysis: Be careful with smart contracts, and never give permission to contracts whose workings you do not fully understand.

• Secure Wallets: Use hardware wallets to store the majority of your funds. Better safe than sorry.

• Awareness: Continually educate yourself on new threats and stay informed about best practices to secure your assets.
