Hackers target US firms in FastJson RCE zero-day attacks
July 27, 2026
Back to all postsRecent cyberattacks, known as FastJson Remote Code Execution (RCE) zero-day attacks, have targeted U.S. companies. These attacks exploit a vulnerability in the popular Java library, FastJson, which is used for handling JSON data. The vulnerability allows hackers to run malicious code on affected systems, potentially leading to data breaches and system takeovers. Given that many Canadian businesses use FastJson, this issue poses a significant risk to our local SMBs and IT managers. It underscores the importance of keeping software up-to-date, implementing robust security measures, and being vigilant against emerging threats.
