Malware found on some new Apple M1 Macs mystifies experts

Hackers appear to have wasted little time in targeting Apple’s recently launched Mac computers featuring its new M1 chip.

Colorado-based security firm Red Canary says it has discovered malware on nearly 30,000 Mac computers globally, though experts are currently trying to work out its precise purpose.

The malware, dubbed “Silver Sparrow,” is described as a “previously undetected strain,” though another version of it had Intel-made equipment in its sights, according to Red Canary.

According to Arstechnica, researchers have discovered that the mysterious malware is set up to check a control server once an hour. It does this to determine if there are any new commands for the malware to run. But up to now, no commands or payloads appear to have been delivered to the infected computers, leaving experts wondering what may be coming down the track.

The malicious software also incorporates a self-destruct capability that, if and when directed, enables it to remove itself from a computer.

Red Canary says that according to data provided by California-based security firm Malwarebytes, Silver Sparrow had infected 29,139 Mac computers in 153 countries as of February 17, with cases mainly concentrated in the U.S., Canada, U.K., France, and Germany.

Given what it currently knows, Red Canary says the malware presents a “reasonably serious threat” to infected Mac computers.

“Though we haven’t observed Silver Sparrow delivering additional malicious payloads yet, its forward-looking M1 chip compatibility, global reach, relatively high infection rate, and operational maturity suggest Silver Sparrow is a reasonably serious threat, uniquely positioned to deliver a potentially impactful payload at a moment’s notice,” Red Canary said in a blog post detailing what it knows so far about the malware.

It added: “The ultimate goal of this malware is a mystery. We have no way of knowing with certainty what payload would be distributed by the malware, if a payload has already been delivered and removed, or if the adversary has a future timeline for distribution. Based on data shared with us by Malwarebytes, the nearly 30,000 affected hosts have not downloaded what would be the next or final payload.”

The company’s post shares details about how it was able to detect Silver Sparrow using checks that can also uncover other MacOS threats.

Many people may still be of the belief that Apple-made computers don’t get malware. This, of course, isn’t true, and so Mac owners should be certain they have the proper protections in place to ensure their machines have the best chance of keeping hackers at bay.

UPDATE: Apple has reportedly taken steps to prevent additional Mac computers from being infected with the malware.

New MacBooks are coming, but they aren’t worth waiting for

Ah, yes -- the eternal question MacBook buyers have: Is it worth waiting?

On the surface, it might seem like it. After all, we're at the beginning of a new chip refresh cycle, with Apple launching the M3 in November. But if you're looking at buying any of the available MacBooks, I'd say you're in a good spot to buy one that's currently available and not regret your choices come next year.

I’m finally ready to stop recommending Apple’s cheapest MacBook

Apple’s MacBook lineup is a bit all over the place at the moment. It’s full of fantastic machines that trounce the competition, yet picking the right Mac for you has never been more confusing. But amid all the uncertainty, one thing is for sure: I can finally stop recommending the M1 MacBook Air.

For years now, the M1 MacBook Air has been a great choice for anyone looking to dip their toes into the world of Apple laptops. But three years after its launch, it’s no longer looking like the solid purchase it used to be.

I’m a laptop reviewer. Here’s why I still use a laptop from 2021

I'm pretty much always using a new laptop as my daily driver -- whichever one that I'm testing for review. And in 2023 alone, I've reviewed almost 40 machines, ranging from near-budget machines with solid performance and impressive features all the way up to innovative devices like the HP Spectre Foldable PC.

But occasionally, there's a lull in new releases, which gives me a chance to do a gut check. Which laptop do I return to as my primary work machine? To my own surprise, it's none of the flashy new releases from 2023. It's a laptop from way back in 2021 that remains my favorite. Not coincidentally, it's the only laptop I've purchased myself in years. That laptop is the first-gen Apple MacBook Pro 14, and it's held up so well against the competition that I still haven't felt compelled to replace it. Here's why.
