Hackers have improved their browser attack: how to protect your cryptocurrencies from the new threat

SlowMist, a company specializing in blockchain ecosystem security, recently released a detailed analysis of cyber threats faced by users in late 2025. The research results revealed a troubling trend: malicious actors have adapted their attack methods, making them much more complex and sophisticated. Researchers highlighted two main directions hackers use to compromise user wallets.

The Latest “Browser History Poisoning” Technique: How Hackers Deceive You

One of the most dangerous methods developed by hackers is called “browser history poisoning.” This complex scheme exploits the autofill feature to redirect users to fake websites.

The attack mechanism works as follows: even if you carefully enter the correct official service address, your browser may automatically suggest and redirect you to a counterfeit site. This happens because malicious actors pre-infect the browser history by loading fake domains through ads, social media redirects, or highly convincing fake links. As a result, the fake domain becomes embedded in the autofill system.

The SlowMist report emphasizes: this is not user error. The browser simply operates according to its logic, offering the most frequently visited addresses. When you try to revisit the official site, the system recognizes the previously “poisoned” address and automatically suggests it.

The outcome is particularly dangerous because the phishing site you are redirected to is almost identical to the original. Users instinctively enter their credentials, unaware that they have fallen into a hacker’s trap.

The Return of Malicious Software Attack Waves

Alongside the development of phishing methods, there is a significant increase in malicious software activity targeting users’ computers. Hackers install malware covertly, using classic attack vectors:

• Phishing hyperlinks embedded in messages or ads
• Private messages on social media appearing as official notifications
• Files disguised as utilities, tools, or download resources

When a device is compromised by such software, user data—especially private keys and wallet credentials—are at serious risk. Malicious software often acts as spyware, intercepting keystrokes and accessing sensitive information.

How to Protect Yourself from Hackers: Practical Security Tips

SlowMist recommends users take several critical measures:

First, never rely solely on the browser’s autofill feature, especially when accessing cryptocurrency platforms. Use your own bookmarks containing only verified links, and always access sites through them instead of typing addresses into the search bar.

Second, exercise maximum caution with files and links from unknown sources. If you are unsure of a file’s origin, it is better not to download it.

Third, regularly check your browser history and delete suspicious entries. Some browsers offer security data clearing features.

While it is impossible to be completely safe from hackers, following these rules significantly reduces the risk of compromising your cryptocurrency assets and personal data.
