How To Check Macos High Sierra For Malware

Anything from Apple's download servers is an update, and not a full installer for that version of the operating system. The only full upgrade installers are in the Mac App Store, and here is the link to How to upgrade to macOS High Sierra.

Click “Go” and check whether there is any weird looking plists or ones with with garbled/random file name. If you find some, delete ‘em and restart your Mac. Removing all plists with adobe in the name fixed my problem. By the way, a plist file is a settings file, also known as a “properties file,” used by macOS applications.

Sep 26, 2017 Not upgrading to macOS 10.13 High Sierra won't keep you safe from this sort of attack. Wardle said on his blog that the flaw also exists in macOS 10.12 Sierra, and probably on OS X 10.11 El.

Sep 05, 2016 macOS Sierra (10.12) MacRumors attracts a broad audience of both consumers and professionals interested in the latest technologies and products. We also boast an active community focused on purchasing decisions and technical aspects of the iPhone, iPod, iPad, and Mac platforms.

Before you leap from Yosemite, check the specific printer/scanner vendor driver sites to verify if either have High Sierra driver support. Also check with your third-party applications vendor sites that their applications remain compatible with High Sierra, and preferably, are 64-bit applications. Although the vendor sites are the last word on application support, you may find RoaringApps helpful too.

I would also recommend the following:

Download and run the free Malwarebytes for Mac before any upgrade to see if any malware presently exists on your Mac, and if found, can be removed. Subscription for continued realtime features is purely optional.
Boot into Yosemite Recovery (⌘-R) and run Disk Utility First Aid on your startup drive.
Perform one last Time Machine backup before the upgrade.

Security research and former NSA staffer Patrick Wardle says that he will demonstrate on Sunday a set of automated attacks against macOS High Sierra, in which he is able to bypass security checks.

The checks are ones that ask the user to confirm that an app should be granted permission to do things like access contacts or location data …

He was quick to point out that the exploits would not allow an attacker initial access to a Mac. But it would effectively get around Apple’s sandboxing, to allow one malicious app to gain additional permissions.

Wired reports that the exploits rely on what’s known as ‘synthetic clicks,’ in which rogue code mimics a user clicking a button to grant a permission.

At the DefCon hacker conference Sunday in Las Vegas, Wardle plans to present a devious set of automated attacks he’s pulled off against macOS versions as recent as 2017 release High Sierra, capable of so-called synthetic clicks that allow malware to breeze through the permission prompts meant to block it. The result could be malware that, once it has found a way onto a user’s machine, can bypass layers of security to perform tricks like finding the user’s location, stealing their contacts or, with his most surprising and critical technique, taking over the deepest core of the operating system, known as the kernel, to fully control the computer.

“The user interface is that single point of failure,” says Wardle, who now works as a security researcher for Digita Security. “If you have a way to synthetically interact with these alerts, you have a very powerful and generic way to bypass all these security mechanisms.”

Wardle had previously achieved the same thing using accessibility features. Apple issued a patch to block this, and he then discovered a further workaround. Wardle says the greatest risk is that one rogue app can now potentially use this technique to take control of the kernel – something which ought to be impossible.

If malware can use that trick to install a kernel extension, it can often exploit that added code to gain full control of a target machine. Kernel extensions—like drivers in Windows—must be signed by a developer for MacOS to install them. But if an existing signed kernel extension has a security flaw, a piece of malware can install that extension and then exploit its flaw to take control of the kernel.

“A lot of advanced malware really tries to get into the kernel. It’s like god mode,” Wardle says. “If you can infect the kernel, you can see everything, bypass any security mechanism, hide processes, sniff user keystrokes. It’s really game over.”

It appears that the exploits are patched in Mojave.

Apparently this is fixed in Mojave — synthetic events are not allowed in Mojave without user approval for the app that wants to post them. https://t.co/NntzcmB6uo

Some are reporting that Apple also seems to be attempting to block synthetic clicks in macOS 10.13.6, though the extent to which this is successful is as yet unclear. We should learn more on Sunday.
