A cybersecurity specialist has developed the world's first ransomware that integrates directly into a computer's central processing unit, making it virtually invisible to antivirus programs and extremely difficult to remove.

A Revolution in Malicious Software
Cybersecurity expert Christiaan Beek from Rapid7 has achieved a breakthrough in malware research by creating the first-ever sample of ransomware that integrates directly into a computer's central processing unit (CPU). This discovery marks a turning point in the evolution of cyber threats.
An Unprecedented Threat
The distinctive feature of this development is that malware operating at the processor level is virtually impossible to detect with existing antivirus solutions. Moreover, such a virus persists in the system even after completely replacing the drive containing the operating system—the traditional method used to eliminate complex infections.
History and Technical Aspects
While malware operating at the processor microcode level has previously existed in the form of UEFI firmware rootkits, this is the first time a researcher has successfully implemented ransomware in this format—one of the most dangerous and financially motivated types of malicious software.
The idea to create such a virus came to Beek after studying vulnerabilities in AMD Zen processors. These vulnerabilities theoretically allow attackers to:
- Load malicious microcode directly into the CPU
- Bypass hardware encryption mechanisms
- Modify processor behavior at will
Development Background
Interestingly, such ideas are not new to the cybercriminal community. In 2022, fragments of correspondence from the Conti hacking group were made public, where the possibility of creating processor-level malware was discussed. However, as far as the expert community knows, they never developed a working solution.
"If they were working on this several years ago, I'm willing to bet that some of them at some point will have enough smarts to start creating this thing," noted Christiaan Beek, explaining his decision not to publish the source code of his development, despite characterizing his sample as "amazing."
The Scale of the Ransomware Problem
The emergence of such advanced threats is particularly concerning against the backdrop of ransomware's growing impact on the global economy. According to a recent study conducted by Veeam Software, approximately three-quarters of enterprises in America, Europe, and Australia encountered ransomware attacks of varying severity over the past year.
Implications for Cybersecurity
The emergence of ransomware capable of integrating directly into processors marks a new stage in the confrontation between cybersecurity specialists and malicious actors. Such threats require the development of fundamentally new protection methods that operate at the hardware level.
Processor manufacturers and security system developers will need to find ways to protect against this new category of threats, which may become reality in the near future, given the continuously growing financial motivation of cybercriminals and their pursuit of increasingly sophisticated attack methods.
