Biggest technology companies battle to resolve major security flaw
ll 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.
Almost 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 centers for executing computer programs 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. US giant Intel, as well as its rivals AMD and ARM, have started installing updates. ■
