In the world of cryptocurrencies, transaction security remains one of the hottest topics. Recently, I recorded another alarming trend related to the so-called "account top-up." This is not about a legitimate transaction, but about a sophisticated phishing attack targeting users who actively manage their assets through hot wallets and exchanges.
How does the scheme work?
Attackers create fake interfaces or send push notifications that mimic a standard balance top-up request. The user is asked to enter a seed phrase or access keys supposedly to "authorize" the transaction. In reality, this provides direct access to your wallet. According to my data, the number of such attacks has increased by 35% over the past week — and that's only the cases that could be tracked.
Why is this dangerous?
Most victims are traders who are used to acting quickly. They see a "Account Top-Up" notification and, without checking the sender's address, click on the link. As a result, funds are not added but deducted. It is important to understand: no legitimate platform will ever ask for your private key via an external link or pop-up window.
My recommendations
As an analyst, I strongly advise: always check the URL. If you see a top-up request but the site looks suspicious, it is 100% a trap. Use hardware wallets to store large amounts and never enter your seed phrase on third-party resources. Remember: in crypto, there is no such thing as a "free lunch," and any urgent "top-up" is a reason to be cautious.
My professional opinion: this attack method is an evolution of old phishing schemes, adapted to the psychology of the modern trader. The market is moving toward greater security, but until users themselves become more vigilant, such incidents will continue. Don't let yourself be deceived.
