The 'Error Code: B4259F' pop-ups are fraudulent error messages that can expose your PC to threat-related attacks or redirect you to con artists. Malware researchers have had confirmation of these attacks originating from multiple Web domains and recommend keeping strong browser security features available to block them on contact.

The Error Code Delivered to Your PC with Larcenous Intent

While modern Windows releases manage to reduce the instances of the once-prolific 'Blue Screen of Death,' these error screens are seeing new life in the campaigns of various threat authors and con artists. The 'Error Code: B4259F' pop-ups are one of the latest expressions of this attack methodology, most recently dated in April of 2016. In the past, malware experts have connected the 'Error Code: B4259F' pop-ups to a range of corrupted websites, including p6c8n08h2bkyaty80enw.com, menrljufr3nvxyhwxx.com, and rewards2016.com. Other PC security institutions have yet to categorize most of these websites as being unsafe.

These websites may launch the 'Error Code: B4259F' pop-ups with standard HTML content, displaying fake system alerts based on real Windows error codes. They also may include additional prompts not found in real BSODs: asking that you avoid restarting your machine while recommending a 'technical support' phone number. Like the websites launching the 'Error Code: B4259F' pop-ups, the phone numbers associated with these attacks have been rotating, potentially preventing bogus databases and other blacklist resources from classifying them appropriately.

Calling the number delivering itself through the 'Error Code: B4259F' pop-ups places the victim in the hands of a fake PC support technician. Although the outcomes of these scenarios may vary with the actions of the individuals involved, malware experts often see consequences including loss of sensitive information or cash transfers for fake technical support services. Bank account information, personal identity information, and credit card details are the most common targets for phishing tactics like the 'Error Code: B4259F' pop-ups.

Keeping the Worst of the Web's Code out of Your Browser

Based on past patterns, the 'Error Code: B4259F' pop-ups are at the greatest risk of harming PC users on Windows installations, with observable preferences for targeting Internet Explorer and other, Windows-based browsers. Up to this article's writing, malware researchers have seen no correlations between exposure to the 'Error Code: B4259F' pop-ups and contact with advanced, script-based attacks, such as exploit kits that could download threats onto your PC. However, the wide variety of sites and rotating content related to the 'Error Code: B4259F' pop-ups campaign makes the future introduction of such threats entirely possible.

Occasional, unintended contact with corrupted websites may occur through hijacked advertising networks. Blocking some plugins and script-based Web content, disabling pop-ups, and having browser-based security software can help prevent a browser hijacking from turning into encounters with the 'Error Code: B4259F' pop-ups. Web surfers who accidentally load sites related to the 'Error Code: B4259F' pop-ups or similar phishing tactics should close their browsers and launch appropriate anti-malware scans immediately.

The most meaningful risk of a phishing attack like the 'Error Code: B4259F' pop-ups always is the possibility of you giving money or information to fraudsters. When in doubt, malware experts recommend withholding potentially exploitable information from a third-party, especially one being endorsed by pop-ups imitating Windows warnings that don't belong in your browser.
