New wave of digital attacks: how to protect your crypto assets from emerging threats

The blockchain security company SlowMist recently released the results of its research on security incidents in Q1 2025, revealing a concerning landscape for cryptocurrency users. The report highlights two critical threats: a significant resurgence of malicious programs and increasingly sophisticated fraud techniques that exploit browser predictive behavior.

The “history poisoning” method: how hackers compromise the autocomplete function

One of the most insidious techniques identified by SlowMist is called “browser history poisoning.” This attack works in a sophisticated way: criminals pre-insert fake web addresses into the browser history through various channels such as misleading ads, social media redirects, or fraudulent banners.

When the user later manually types the legitimate domain name of an official platform, the browser’s autocomplete feature suggests the poisoned domain previously saved. The result? The user is involuntarily redirected to a counterfeit site, built with an interface almost identical to the original. This is not user error but deliberate manipulation of the browser’s autocomplete system.

According to the report, victims confirmed they entered the correct web address, yet the browser still auto-completed with a false name, leading them directly to sophisticated phishing pages.

The rise of malware threats: when downloads hide dangers

Meanwhile, SlowMist has documented a significant increase in malware attacks targeting personal devices. Attackers distribute malicious code mainly through three channels: well-crafted phishing links, private messages received via social networks that appear to come from trusted sources, and files disguised as “useful resources” or “trading tools.”

Once the malware infects the device, the risk to personal data and especially to cryptocurrency wallets becomes extremely serious. Attackers can directly access private keys or steal login credentials for trading platforms.

Defensive strategies: how to protect your digital resources

SlowMist recommends a series of cautious behaviors for users. First of all, do not blindly rely on the browser’s autocomplete suggestions, especially when accessing sensitive financial platforms. A much safer practice is to save bookmarks of official platforms and always access them through these, bypassing the browser’s prediction system.

Secondly, it is essential to exercise extreme caution with files and links from unknown or unverified sources, even if they seem legitimate. Before downloading anything, verify the sender’s identity and the source’s reputation.

The key message is that security in the world of cryptocurrencies requires constant awareness: every action, every click, every download represents a potential entry point for criminals. Vigilance remains the most effective defense.
