Intel and Microsoft unveiled a new version of the vulnerabilities for Spectre and Meltdown on Monday, which revealed a vulnerability in the chips assembled in hundreds of millions of computers and mobile devices.
Intel calls the new grade “Option 4”. Although this latest version uses most of the vulnerabilities found in January, it uses a different method to extract confidential information, the company said.
Spectrum and Meltdown continued to be pursued by companies such as Intel, AMD, and Arm, which released chips with flaws for everything from computers and laptops to mobile devices. Vulnerabilities that allow hackers to read sensitive information about your processor have affected hundreds of millions of chips over the past twenty years. While companies such as Microsoft, Intel, and Apple released fixes of these bugs, the fixes did not always work that efficiently and sometimes caused problems to the computer.
Hackers often scan vulnerabilities on the Internet that allow them to attack. For example, the WannaCry ransomware attack was used on Windows computers, which specifically affected the owners who never used the Microsoft patch.
But even after Intel and other companies corrected the first strain, researchers expected new changes in initial susceptibility. In January, Simon Segars, Arm CEO anticipated that a bug like Spectre is likely to happen again. The announcement of Monday is the newest example of companies witnessing an ongoing security challenge.
The company said that this vulnerability was not recognized by hackers and it will issue a full solution to this vulnerability in the coming weeks. Intel vice president for security Leslie Culbertson said in an article that Intel has already made the update available to software vendors and software vendors.
“It is important to note that this method depends on how malicious programs are performed locally,” Arm said in the message.
Researchers of Project Zero from Google, who discovered the first vulnerabilities, reported a problem in February to Intel, Arm, and AMD. The team also rated it as an average risk.
