It’s an open-source system versus Microsoft’s proprietary interface, for one. The Bash shell is very popular with developers and programmers.

Contrast that to Unix-based systems like Mac OSX and Ubuntu, which by default use an input system called the Bash shell – the thing you see any time you open the application Terminal.

What does that mean, practically speaking? For years, if you were interested in command-line control of your Windows computer, you could use Powershell or the Command Prompt – the same basic command-line system that Microsoft has been using since the pre-Windows days of MS-DOS.

That’s like a turducken of operating systems. Microsoft partnered with Canonical, the company that develops the popular Linux operating system distribution Ubuntu, to create a full-fledged Linux/Ubuntu subsystem (essentially Ubuntu 14.04 LTS) inside of Windows 10.

If anyone can compare my md5deep results to a legit version of 6.4 and offer any illumination on what's changed, we would appreciate the assistance.This past summer, Microsoft released its “Anniversary Update” for Windows 10. It included a lot of the business-as-usual sort of operating system updates: enhanced security, improved integration with mobile devices, updates to Microsoft’s “virtual assistant” Cortana (who is totally not named after a video game AI character who went rampant and is currently trying to destroy all biological life in the known universe, because what company would possibly tempt fate like that?) “NO I WILL NOT OPEN ANOTHER INCOGNITO WINDOW FOR YOU, FILTH”īut possibly the biggest under-the-radar change to Windows 10 was the introduction of Bash on Ubuntu on Windows.

But could this simply be an error in diagnosis - or were both of our copies of Xcode 6.4 hacked with XcodeGhost? Could the failed signatures be caused by another attacker? Could Apple's digital signature process have loopholes and failure modes that we're only now discovering? We have no way of answering any of these questions at this point. My friend is frantically updating his version of Xcode and checking his apps. Once he started the process, he found out that spctl calls his version of Xcode bad, too. To see if I could pinpoint which file is bad, I compared my md5deep results with a fellow Mac developer who's also still running version 6.4. You can look at the hash values of my files here.

I used the forensics software md5deep to check out my Xcode.app directory. This will tell you a bit about the digital signature on Xcode:Ĭodesign -display -verbose=4 /Applications/Xcode.app It's possible to find out a bit more by using the command-line utility codesign. Which resource? I don't know and the verbose option won't help me. Applications/Xcode.app: a sealed resource is missing or invalid Apple says these are the only acceptable answers: Spctl -assess -verbose /Applications/Xcode.appĭespite the fact that you'll be using the so-called verbose option, the answer doesn't contain much information. The command-line utility spctl will check the digital signature on applications. I recommend checking your own copy of Xcode using the method recommended by Apple. But I haven't uploaded any new versions in months. I have never downloaded any copy of Xcode from anywhere except Apple servers.īeginning yesterday, I've contected Apple multiple times and the company has not responded.Īpple has not notified me that it has removed any of my apps from the App Store, so I'm assuming the ones I've compiled are fine for now. Well, I tried validating my copy of Xcode using Apple’s validation method, and the results were alarming - the Xcode 6.4 copy on my Mac, installed on July 8, 2015, at 12:24 p.m.

Yesterday morning, Apple sent out an email to developers advising them that Apple had “removed apps from the App Store that were built with a counterfeit version of Xcode, which had the potential to cause harm to customers.”Īpple also suggested, as Fahmida Rashid reported Monday, that counterfeit copies of Xcode downloaded from third-party servers, not Apple’s, were responsible for creating the malware-infected apps. Concurrent with the email, a post on the Apple developer blog appeared suggesting that developers validate their copy of Xcode to ensure it wasn’t a counterfeit copy spewing XcodeGhost malware.
