Scammers will stop at nothing when it comes to stealing cryptocurrency. Some try to sell scarce mining equipment, others lure victims with gifts from cryptoexchanges or Elon Musk himself, or even post screenshots on public platforms with passwords for cryptowallets and collect “fees” from cryptoinvestors enticed by the prospect of a free lunch. Today we tell you about a new giveaway scam and underscore once again why the seed phrase for your cryptowallet must be guarded with your life.
Free money
As is often the case, it all starts with an e-mail. The brains behind this scheme chose as bait an offer to take part in a juicy giveaway of cryptocurrency: Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Tron (TRX) or Ripple (XRP). A total of $800 million no less was at stake! The overly generous scammers were kind enough to provide a simple three-point guide for those wanting to get their free cryptocurrency, plus a link to the “promotion” website.
Let’s take a look at the e-mail. It is signed by the support team of a certain Crypto Community: an association of cryptoenthusiasts, one might think. However, the domain in the sender’s e-mail address has nothing to do with any kind of crypto at all. That does not inspire confidence. The message text is slapdash, and full of errors and typos. The scammers are likely counting on the victim being so taken aback by the nine-figure sum that everything else will slip under the radar.
Phishing e-mail inviting the recipient to take part in a cryptocurrency giveaway
Clicking the link takes the user to a phishing site. Its domain bears no relation to the sender’s address, and in the minimalist design there is no mention at all of any Crypto Community.
At this point, the victim is asked to specify the wallet they want the funds transferred to. The criminals covered all the most common wallets: Blockchain.com, Trust Wallet, MetaMask, Coinbase, Binance, Crypto.com, and Exodus. But users of more exotic wallets have not been forgotten: for them, an Other Wallets button has been provided. User-friendly, isn’t it?
The victim is invited to choose a cryptowallet for the promised transfer of tokens
Now for the most interesting part: to get the coveted tokens, the user must enter a secret series of words, aka – a seed phrase. As soon as they fill in the fields and click the Next button, a notification appears on the screen that everything was successful and the cryptocurrency will be in the lucky winner’s account within 24 hours.
Interestingly, the website has no checks: even if random words or even numerals (which cannot be part of a seed phrase at all) are entered instead, the site still reports a successful transfer. Of course, if the real seed phrase is typed in, far from receiving winnings, the victim will likely be relieved of all their savings.
Any sequence of words and numbers will produce a “successful” transfer
Seed phrase, or the key to all doors
The scammers rely on the fact that people are usually very protective of their private key, which immediately opens access to the cryptowallet; but many do not realize their seed phrase is also top-secret, and think nothing of entering it on a website in anticipation of a reward.
In actual fact, the seed phrase is no less valuable. With it, an attacker can generate a new private key and thus gain access to the victim’s wallet. In other words, the seed phrase effectively affords the same opportunities to pillage your savings as the private key. This means you should protect the former from prying eyes and ears as carefully as the latter.
How to protect your cryptofinances
To wrap up, a few tips to avoid falling victim to cryptoscams:
- Keep your seed phrase secret. Never reveal it to anyone, and enter it only to recover access to your wallet. Do not store the seed phrase in public file-sharing services, or send it via instant messaging apps or by e-mail.
- Do not click on links in e-mails about giveaways, gift payouts, account suspensions or bank account closures. Such e-mails are most likely from cybercriminals. Read our checklist to learn how to spot online scammers.
- Use a reliable security solution that warns you in good time about phishing pages and prevents you from handing over sensitive information to the bad guys.
