Intel processors revealed another vulnerability


Modern hackers are constantly striving to identifyall new vulnerabilities in computer chips. This is especially true for leading brands with a large market and whose processors diverge around the world. Recently, a message appeared about a new Zombieload v2 virus that violates the security of Intel processors, up to the models of the new Core i9 series.

The Zombieload v2 virus carries out an MDS attack,the mechanism of which became popular in the middle of this year. In this threat, not only server processors are exposed, but also top consumer chips, including Intel Core i9-9900K, which have already received protection from Meltdown.

Zombieload v2 algorithm is based on the use oftransactional memory features that were identified back in 2013 with the introduction of Haswell architecture. Working with memory according to TSX instructions leads to numerous errors, which allows hackers to hack. Using the virus, attackers will be able to steal passwords or other personal information located on the infected computer.

Previous version of Zombieload tracked actionsvictims regardless of the degree of software protection. Zombieload v2 uses the asynchronous TAA mechanism, which causes a conflict between read operations in the processor, which provides the ability to steal data that the processor processes.

Intel experts note that the attack withZombieload v2 is complicated enough to implement. However, cyber security experts drew the attention of users to the possibility of leakage of confidential data from computers running on Intel processors.
