Apple devices also affected from chip vulnerabilities

Washington, Jan. 5: Amid a frantic rush to patch a computer security flaw, experts struggled on Thursday to determine the impact of a newly discovered vulnerability which could affect billions of devices worldwide.

Cybersecurity researchers called for computer systems to urgently install updates a day after the release of details of the so-called Spectre and Meltdown vulnerabilities affecting the chips powering most modern PCs and many mobile devices. Researchers on Wednesday published details of the flaw, which unlike many other vulnerabilities stems from the chip itself and how it safeguards private data stored on computers and networks.

The researchers at Google showed how a hacker could exploit the flaw to get passwords, encryption codes and more, even though there have been no reports of any attacks using the same vulnerability. “The full extent of this class of attack is still under investigation and we are working with security researchers and other browser vendors to fully understand the threat and fixes,” said Mozilla researcher Luke Wagner in a blog post.

The revelations “attack the foundational modern computer building block capability that enforces protection of the (operating system),” said Steve Grobman, chief technology officer at security firm McAfee.

“Businesses and consumers should update operating systems and apply patches as soon as they become available.”

Chipmaking giant Intel — the focus of the first reports on the flaw — said the company and its partners “have made significant progress in deploying updates” to mitigate any threats.

“Intel expects to have issued updates for more than 90 per cent 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.”But John Bambenek, a Fidelis security researcher who works with the SANS Internet Storm Center, warned that it may be too soon to know the extent of the problem. “This bug is probably worth its name and logo considering the pervasive nature of the vulnerability,” Mr Bambenek said.

Apple said, “All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time.”
