A technique designed to speed up computer processing has turned out to leave a treasure trove of information for hackers, unsecured in cache memory on each chip.
While it's urging to see that Xbox is unaffected, different sorts of devices from PC to telephones, and web servers, still aren't completely checked. The material defect also lets hackers use code running in a browser to access memory in the attacker's process, potentially exposing customers' passwords and personal information.
But even if the performance impact is inconsequential, AMD could win business simply by not being at the center of this storm.
The latter two companies issued immediate statements concerning the flaws soon after they were revealed, yet Intel was a little slower to react. The assumption here is that further updates may be needed, and that things will only improve over time. Chip makers will have to redesign future processors that will be protected against the exploits and its variants.
When investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
The chipmaker is working with rivals AMD, ARM and others in an industry response to the revelation of serious CPU security flaws disclosed recently. Software-based solutions can act as a stop-gap measure against the threat, but until vendors update their chip designs, Spectre will remain a problem.
November 29, 2017: Krzanich sells more than $39 million worth of Intel stock, in accordance with the revised trading plan adopted just weeks earlier. In a statement to CNBC, AMD explained the difference in architecture between Intel and AMD chipset puts AMD at "zero risks".
As the cloud provider community mobilises to protect users from two long-standing processor-based security flaws, researchers suggest a rip and replace of their underlying CPU hardware may be required to eradicate the risk of exploitation. "This is a flaw that's not at the operating system level; it's at the chip level". Microsoft released a security update for Windows computers to mitigate Meltdown on Wednesday.
Apple already patched the nasty security flaw in its Mac platform last month with the macOS High Sierra 10.13.2 release. "GCP has already been updated to prevent all known vulnerabilities". This means that their processors have a lot more secure procedures when accessing private data on the users' PC compared to Intel.
Despite the patching, the security researchers say the Spectre security flaw, although harder to exploit, is also more difficult to fully patch.
