November 20, San Francisco Apple has released a software update to fix issues that hackers are “actively exploiting” to attack Mac computers with Intel processors.

The tech giant acknowledged two flaws that “may have been actively exploited on Intel-based Mac systems” in a security alert.

They are referred to as “zero day” vulnerabilities. Apple provided a macOS software update (named macOS Sequoia 15.1.1) to address those issues, along with improvements for iPhones and iPads, including those using the outdated iOS 17 software.

“An arbitrary code execution may result from processing maliciously generated online content. The firm said, “Apple is aware of a report that suggests this vulnerability may have been actively exploited on Intel-based Mac systems.”

It also said that enhanced checks were used to remedy the problem. How many Mac users have been attacked and who is responsible for these assaults are yet unknown.

Google’s Threat Analysis Group security experts were the ones who revealed the flaws.

These flaws affect WebKit and JavaScriptCore, the web engines that execute web content and power the Safari browser.

As soon as possible, Apple consumers should upgrade their Macs, iPhones, and iPads.

The tech behemoth Apple warned iPhone owners in at least 98 countries, including India, in July of a possible new mercenary malware assault similar to “Pegasus.”

“You are being targeted by a mercenary spyware attack that is trying to remotely compromise the iPhone associated with your Apple ID,” the Apple alert states.

This assault is “probably targeting you specifically because of who you are or what you do,” the iPhone manufacturer said in the warning.

Selected customers in 92 countries, including those in India, received danger alerts from the tech giant in April of this year. These users may have been the targets of “mercenary spyware” like Pegasus from the NSO Group.
