To prevent being infected by Mac malware of any sort, pay close attention to the dialogue boxes that pop up on your screen. "As Apple has revoked the certificate, the malicious application will no longer run on macOS (unless of course, the attackers re-sign it with another certificate)," wrote Wardle in his blog post. For now, you're safe from it on Big Sur, but that may change. That's what Apple has done with the GoSearch22 adware. That doesn't block malware from being installed - a developer ID is easy to buy or steal - but it does mean that Apple can revoke the developer's certificate, effectively blocking the software. "Several industry-leading AV engines (who readily detected the x86_64 version) failed to flag the malicious arm64 binary," wrote Wardle.Īll software that runs on macOS Big Sur needs to be digitally "signed" by a registered Apple software developer. Wardle uploaded samples of both to VirusTotal, and as of this writing, 16 antivirus engines caught the x86-64 version, 14 the ARM64 one. What's more concerning is that while many of the best Mac antivirus programs catch the regular version of GoSearch22, fewer detect the M1-coded version. You do want to make sure it's not on your Mac, however.

But there's no evidence yet that GoSearch22 does steal data or result in more malware being installed on Macs.

One online malware-removal guide notes that GoSearch22 is similar to adware that "tend to be designed to collect browsing data" and may display ads that can "download and/or install unwanted apps by executing certain scripts." "Its main goal, objective, seems to be related to financial gain via ads, search results, etc."

"It seems like fairly vanilla adware," Wardle told Motherboard's Lorenzo Franceschi-Bicchierai. And it's a fat binary with code for both x86-64 and ARM64 chips, indicating it was created to run on Macs rather than iOS devices. It's a derivation of the older Pirrit adware, first spotted in 2016 and still plaguing Macs. He got more than 200 results, but most were for iOS jailbreaking software that was built to run on both older and newer iPhone/iPad chips. So he searched in the online VirusTotal database for malware that met all the right parameters.Īmong other things, it had to be written for macOS or iOS, contain ARM64 instructions, support more than one chip architecture, be digitally "signed" by an Apple developer and be detected as malware by at least two antivirus engines. Wardle wondered if any known malware was secretly using fat binaries that hadn't yet been spotted.

"Malware authors have now joined the ranks of developers (re)compiling their code to ARM64 to gain natively binary compatibility with Apple's latest hardware." "I figured it would make sense that (eventually) we'd see malware built to execute natively on Apple new M1 systems," Wardle wrote in a blog post this past weekend. GoSearch 22 has been known of for a couple of months, but until independent Mac security researcher Patrick Wardle had a look at its code, it wasn't clear that a second version had been created to run natively on the M1 processor.

Plus: Windows 10 just stole the best macOS feature - but there's a catch.

Anyone can hack your Mac unless you patch it now - here's how.

For the moment, its installation is blocked on the most recent versions of macOS, yet that could change. It often comes secretly bundled with free online software. The malware, called GoSearch 22, is adware that hijacks browser search results, injects ads and might possibly also steal data.
