Security researchers have discovered a previously undetected piece of malware affecting Mac users around the world, including the new M1-powered Macs. Red Canary researchers say that this 'Silver Sparrow' malware forces infected Macs to check a control sever once per hour, but the actual threat remains a mystery.

As reported by Ars Technica, the researchers have yet to observe an actual 'delivery of any payload' on the infected machines. Therefore, the ultimate goal of this malware is unknown.

The malware also comes with its own 'self-destruct' mechanism, but there's no evidence that it has yet been used. Silver Sparrow has been found found on 29,139 macOS endpoints around the world:

Malware for the M1 Macs are like London buses. You wait ages for one, then two come along at the same time. Well, 'the same time' might be pushing it a little, since malware outbreaks - if. Malware authors interested in backdoors will often try to set up a server on an unused port to listen out for connections. A good example of this is the recent Zoom vulnerability, which forced the company to push out an emergency patch in an attempt to address a zero-day vulnerability for Mac users. Zoom have been running a hidden server on. QSearch Mac Virus. QSearch virus on Mac is what lots of describe as a web browser hijacking application or undesirable program. Such applications intend to attack Google Chrome, Mozilla Firefox, Safari, Opera and also various other browsers to alter their default search to QSearch.
The malicious binary is more mysterious still, because it uses the macOS Installer JavaScript API to execute commands. That makes it hard to analyze installation package contents or the way that package uses the JavaScript commands.

Its use of Amazon Web Services and the Akamai content delivery network ensures the command infrastructure works reliably and also makes blocking the servers harder.
The Silver Sparrow malware also runs natively on Apple's M1 chip. This makes it the second piece of malware discovered that is optimized for Apple Silicon, with the first coming earlier this week. This doesn't mean that M1 Macs are specifically targeted, but the malware can equally affect M1 Macs and Intel Macs.

Optimization for the M1 chip combined with things like the infection rate and maturity is what worries Red Canary researchers:
'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. Given these causes for concern, in the spirit of transparency, we wanted to share everything we know with the broader infosec industry sooner rather than later.'
Again, so far researchers haven't yet found that the binary does anything — but it's a threat that looms. You can read more on the Red Canary blog post right here.
