"All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time," Apple -- whose devices are usually regarded as secure -- said in a post on an online support page on Thursday.

Amost all microprocessors produced over the past 10 years by Intel, AMD and ARM are affected. No PC or mobile device can function without the miniature components that are effectively nerve centres for executing computer programmes and apps.

And that is what distinguishes them from previous security alerts that have tended to involve software rather than hardware.

In theory, Spectre and Meltdown could enable a user to "access kernel level memory access, exposing critical information that would be stored there, like system passwords," said Chris Morales, head of security analytics at Vectra.

Luke Wagner, a software engineer at Mozilla, wrote on a security blog that it was "possible to use similar techniques from web content to read private information".

Effectively, all electronic devices manufactured all around the world in recent years contain potentially vulnerable chips.

The biggest names in the sector, including Amazon, Google, Microsoft and Mozilla, are now rushing out updates and patches to eliminate the flaw.

Intel says it has made quick progress with updating vulnerable chips© Provided by AFP Intel says it has made quick progress with updating vulnerable chips US giant Intel, as well as its rivals AMD and ARM, have started installing updates.

In a statement on Thurday, Intel said it and its partners "have made significant progress in deploying updates" to mitigate any threats.

"Intel expects to have issued updates for more than 90 percent of processor products introduced within the past five years," an Intel statement said.

"In addition, many operating system vendors, public cloud service providers, device manufacturers and others have indicated that they have already updated their products and services."

Apple, for its part, advised only getting apps from its online App Store which vets programmes for safety, and said it has already released some "mitigations" to protect against the exploit and planned to release a defensive update for Safari on macOS and iOS in the coming days.

Intel reveals chip design flaw that could have allowed hackers to access hidden info

  Intel reveals chip design flaw that could have allowed hackers to access hidden info Hardware and software manufacturers including Apple and Microsoft began pushing out patches that protected against attacks making use of the flaw. The flaw, which Intel dubbed a side-channel analysis attack,  was discovered "months ago" Intel CEO Brian Krzanich said on CNBC Wednesday. The discovery was made by researchers at Google's Project Zero security group, which reported it to the affected companies. The vulnerabilities undermine some of the most fundamental security constraints employed by modern computers, said Craig Young, a researcher at computer security company Tripwire.

Difficult to exploit?

But some experts believe that the only real "fix" in some cases would be replacing the chip itself, which would be a huge issue for the computing industry.

That said, the experts concede that hacking the chips would require a very high level of technical expertise and the risks were therefore limited.

The US Computer Emergency Readiness Team (CERT) said that it was "not aware of any active exploitation at this time."

In Germany, the BSI Federal Office for Information Security, similarly found no evidence of any "active exploitation" of the flaw, but still sector players to protect themselves "as quickly as possible."

In addition to the security flaw, Intel found itself in hot water Friday over the announcement that its chief executive had sold some of his shares in the company.

According to the specialist magazine Solutions Numeriques, Intel was aware of the existence of the security flaw in its chips at the end of November. But in the fourth quarter of last year, CEO Brian Krzanich sold nearly 900,000 shares, halving his stake in the company, according to Bloomberg.

A company spokesman told Bloomberg that the sale had nothing to do with the issue of the security flaw, insisting that Krzanich had exercised options according to a pre-set timetable agreed long before.

Intel shares lost nearly two percent to close at $44.43 on Thursday, after already dropping 3.4 percent the day before.

Finnish firm detects new Intel security flaw .
A new security flaw has been found in Intel hardware which could enable hackers to access corporate laptops remotely, Finnish cybersecurity specialist F-Secure said on Friday. F-Secure said in a statement that the flaw had nothing to do with the "Spectre" and "Meltdown" vulnerabilities recently found in the micro-chips that are used in almost all computers, tablets and smartphones today.
