Modern Processors Discovered to be Vulnerable to New Attacks

The new study by researchers from Graz University of Technology and CISPA Helmholtz Center for Information Security shows that today affecting almost all modern processors revealed a security vulnerability. The study published by the researchers also explained how hackers obtained sensitive information.

Also from this link According to the research you can access, attacks based on microarchitecture are actually attacks in the kernel. due to user space being 'dereferenced' it was happening. This is the attacks not only the latest generation Intel processors, but also ARM, IBM and AMD Processors such as This means it may be vulnerable to attacks.

Wrong precautions were taken as a result of wrong conclusions:

According to the study, this vulnerability is Meltdown And Foreshadow It was the vulnerability that made attacks against modern processors such as possible. Therefore, hardware manufacturers actually close the security vulnerability with the precautions and updates they install on their systems. they couldn't close it, because the real source of the problem was misunderstood.

The researchers who published the study made a statement to The Hacker News. According to that statement, researchers for more than 4 years In published academic articles, the causes of the problem were not fully understood, which led to wrong measures being taken.

According to the results of the study, with the emergence of the real reason behind the attacks, new side channel attack It also emerged spontaneously. To demonstrate the impact of these attacks, researchers used a process running on an Intel Core i7-6500 U processor. a confidential transaction managed to transfer data.

However, according to the study, some attacks occur in internet browsers. With the use of JavaScript It could be done remotely. According to researchers, in order to prevent these attacks, processors such as 'repoline' should be installed. Spectre-BTB risk mitigation needs to be activated.
