New security flaw in Intel chips called ZombieLoad could affect millions

New security flaw in Intel chips called ZombieLoad could affect millions

Yesterday, Intel disclosed a new attack on its processor dubbed "ZombieLoad", following in the footsteps of last year's "Spectre" and "Meltdown" security snafu.

It affects most Intel processors released since 2011. Unfortunately for Intel, a new issue has now popped up, known as "Zombieload", which has a similar effect to Meltdown, creating a backdoor into PCs via the CPU.

On Tuesday, Intel and a group of cybersecurity researchers published details on four new potential chip attacks that exploit the same "speculative execution" process, which is used to improve CPU performance, that was central to Meltdown and Spectre. The RIDL attack would leak information from different security buffers inside the Intel processors, while an attack called Fallout would allow an adversary to read data recently written by an operating system.

Taken together, the three exploits against four vulnerabilities cover processors dating back to 2008.

He has a history of performing special investigations - in 2008 he was assigned by Attorney General Michael B. Several other media outlets also reported Durham has been tapped to lead the inquiry.

'Even if home users used their browsers to visit a website with an advert or other content with a malware Java programme, the hacker could still steal information, ' the researchers say. Alongside Intel, major tech companies such as Apple, Google, Microsoft, and Mozilla have begun to work on patches for their products. The official reference number for Zombieload is CVE-2019-12130 and the latest Intel microcode update puts protections in place to mitigate the issue. The vulnerabilities also open the door for attackers to nab passwords, sensitive documents and encryption keys directly from a CPU. So, always keep your system updated with the latest security patches in order to stay protected from the vulnerability.

Security researchers have revealed the Zombieload Attack to the public.

Microarchitectural Data Sampling (MDS) vulnerabilities are hard to exploit and are classified as low to medium severity according to the Common Vulnerability Scoring System (CVSS).

KitGuru Says: The unveiling of Zombieload/MDS comes at an unfortunate time, as Computex is right around the corner and Intel is due to release new CPUs very soon.
