  • Meltdown & Spectre: Intel Security Flaw Puts Smartphones & Computers At Risk!

News that computer security experts have discovered two major security flaws in Intel chips that could allow hackers to steal the entire memory contents of a computer have hit the company's shares.

Amazon said in a statement that "all but a small number" of its Amazon Web Services cloud servers "are already protected", and that the remainder would be updated and shielded by Wednesday night.

The researchers that uncovered Spectre write, "As it is not easy to fix, it will haunt us for quite some time". According to an SEC filing, the holdings that Krzanich sold in November - 245,743 shares of stock he owned outright and 644,135 shares he got from exercising his options - were divested under just such a trading plan.

Earlier Wednesday, Tatu Ylonen, security researcher at SSH Communications Security, noted that the flaw, if exploited, could allow hackers to gain access to private data, including passwords, banking data and encrypted or classified information.

We have seen Equifax being attacked, Deloitte has also fallen victim, and WannaCry and Petya became an epidemic to thousands of businesses across continents.

"By 2020, effectively, unless something changes, cybercrime will be responsible for more than the loss of one Twin Tower every year, on an ongoing basis".

"All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time", Apple said in a statement. Meanwhile, Spectre affects some chips in smartphones, tablets and computers powered by Intel, ARM and AMD. He also denied reports that the vulnerability was a flaw, or that it was specific to Intel. For example, an unauthorized party may read sensitive information in the system's memory such as passwords, encryption keys, or sensitive information open in applications.

The vast majority of Google products (including products that run Google operating systems like Android) already have a fix for the exploit in place. Researcher Daniel Gross of the Austrian Graz University of Technology, one of Meltdown's founders, along with Google analyst Jan Horn, said that "this is probably the worst problem in a central processing unit that has ever been found".

The researchers said Apple Inc and Microsoft Corp had patches ready for users for desktop computers affected by Meltdown. Google revealed that the problem had been known to manufacturers since the summer of 2017.

Google researchers discovered the bugs 'Meltdown' and 'Spectre' as essential functions of Intel's hardware. It advised customers to update on their end as well. With Intel processors in this situation, additional page tables were generated, but inaccessible to the program in user mode. These efforts focus on implementing kernel page-table isolation, or KPTI, which splits page tables (currently shared between kernel space and user space) into two sets of data, one for each side. "However, Intel is making this statement today because of the current inaccurate media reports". Meltdown flaw can be fixed by a patch which builds a stronger wall of protection around the kernel. Cyber war. And that 'cyber' could soon turn physical on data centres.

The cloud giant reassured users that the remaining instances will be completed in the next several hours, with associated instance maintenance notifications.

Common ways to do this are to offer 'packs' that claim to solve all your different device issues which contain everything from system malware to bitcoin mining software. Linux kernel 4.14.11 patches this vulnerability and is available now.
