A new cybercrime tool called ErrTraffic has emerged, simplifying malware dissemination through deceptive fake error messages that prompt users to address non-existent issues. The attacks begin on compromised websites, where users encounter distorted text and pop-ups suggesting a browser update or font installation. Clicking the provided button copies a command to the clipboard, instructing users to paste it into PowerShell, which triggers the malware infection. ErrTraffic automates this process, requiring minimal investment for attackers to access a control panel and scripted payload delivery. It operates via JavaScript injection, adapting to the user's operating system and browser to display tailored messages. This method effectively bypasses traditional malware defenses, achieving high conversion rates, with nearly 60% of users following through with the instructions. Infected devices may deploy infostealers or banking trojans, with the system designed to evade law enforcement by excluding certain regions. To mitigate risks, users should avoid copying commands from websites, trust built-in update notifications, use robust antivirus software, and regularly remove personal information from data broker sites.
