https://browndan648.weebly.com/blog/mac-cleaner-deutsch. A decade-old Windows malware trojan wormed its way into the macOS ecosystem, complete with a signed (likely stolen) Apple developer certificate. The exploit appears as an Adobe Flash Player installer. Once permission is granted, it hides itself deep inside macOS folders. Its certificate has already been revoked by Apple, but it's good to be aware of your enemies.
According to Fox-IT, Snake, a malware framework that has been infecting Windows software since 2008, and more recently Linux, is now targeting Mac.
Now, Fox-IT has identified a version of Snake targeting Mac OS X.As this version contains debug functionalities and was signed on February 21st, 2017 it is likely that the OS X version of Snake is not yet operational.Fox-IT expects that the attackers using Snake will soon use the Mac OS X variant on targets.
Snakes are dangerous and here's why
Similar to the Dok trojan that we heard about earlier this week, Snake popped up with an authenticated developer certificate, which means the Mac's built-in security system, Gatekeeper, would consider it legit and allow the installation process to complete.
It's important to note that Apple has already revoked this fake or stolen developer certificate, so Gatekeeper will block it. However, there is still a slight chance of someone downloading Snake by accident if they've found it through dubious channels. Malwarebytes explains:
Fortunately, Apple revoked the certificate very quickly, so this particular installer is no further danger unless the user is tricked into downloading it via a method that doesn't mark it with a quarantine flag (such as via most torrent apps).
How Snake slithers into your Mac
Just like most malware attacks, Snake doesn't just magically appear on your Mac one day. There isn't someone shooting corrupted files through your ethernet cable directly into your software. Snake has to be welcomed into your operating system by you.
Think of it is a vampire. If you don't invite it into your home, it can't attack you.
The file, named Install Adobe Flash Player.app.zip, will appear to be an Adobe Flash installer (Say what you will about Flash, but there are still a lot of people that have to use it for school or work). From Malwarebytes:
If the app is opened, it will immediately ask for an admin user password, which is typical behavior for a real Flash installer. If such a password is provided, the behavior continues to be consistent with the real thing.
Interestingly, once the installation is complete, Flash is actually installed on the Mac, making it even more difficult to tell that it's a trojan.
How you can protect yourself against Snake
As noted above, the fake/stolen developer certificate that allowed Snake to get a pass from Gatekeeper has already been revoked, so it's likely that, even if you download the zip file and try to open the app, your built-in security program will say, 'Nope Dope!'
But to refresh best practices, if you receive an email with an attachment at all, do some due diligence to make sure it's from a legitimate source. Check the sender address to make sure it is from an address you recognize. Click on the sender's name to view the email address it was sent from to make sure it's not a spoofed email. If you're still unsure, confirm with the sender by texting, calling or sending a separate email asking if the attachment is legit.
Specific to the Snake trojan, avoid downloading any zip files with the name Install Adobe Flash Player.app.zip.
What to do if Snake already bit you
Do you like my snake puns?
If you think you might have managed to accidentally install the Snake trojan onto your Mac, you can find and delete the following files:
/Library/LaunchDaemons/com.adobe.update.plist
/Library/Scripts/installd.sh
/Library/Scripts/queue
/var/tmp/.ur-*
/tmp/.gdm-socket
/tmp/.gdm-selinux
Next, delete the stolen/fake signed Apple Developer certificate.
Launch Finder.
Select Applications.
Open your Utilities folder.
Double-click on Keychain Access.
Select the certificate named Adobe Flash Player installer with the signed certificate issued to Addy Symonds.
Right or Control + click on the Certificate.
Select Delete Certificate from the drop down options.
Select Delete to confirm that you want to delete the certificate.
Lastly, change your administrator password to ensure that you're backdoor is rekeyed so the hackers can't get back in.
Remember best practices for staying safe
It is unlikely, at this point, that Snake will slither through your Mac's backdoor. For one, Apple has revoked the certificate, which makes it nearly impossible to make it through the installation process without you knowing about it.
To reiterate, don't open attachments from unknown sources. Double check the sender email address to make sure it is not spoofed. Don't open suspicious-looking files or give administrator permission to unknown programs. Download imessage to mac. You can protect yourself from attacks if you stay safe.

Got a message that says you have to update Flash Player on Mac? Don’t promptly click the update button. If you are not careful, you can accidentally install adware or malware instead of Flash Player. And that’s not what you need, right?
In this article we’ll show you the best way to check for Flash updates and also give you a comprehensive guide to update Adobe Flash Player for Mac safely. Plus, we’ll tell you how to uninstall it from your computer completely.
What is Flash Player?
For years, Adobe Flash Player has been one of the most popular plug-ins used by web browsers to reproduce videos, web ads, and interactive animations. But now its position is rocked by some security concerns and safer alternative solutions.
Google Chrome and Firefox contain the built-in version of Flash running in the sandboxed mode. This method is safer than running Flash as a plugin. What about Safari, it disables Flash Player by default starting from macOS Sierra. The point is that Apple wants you running on HTML5 — the newer and safer way of browsing the web. It supports the same multimedia elements as Flash but without any security issues.
However, the reality is that you still may need the Adobe Flash Player on your Mac. Many websites will not work if you uninstall it completely. Live streams like BT Sport can only be delivered in Flash, so if you are the BT Sport customer, you’ll want to keep the Flash Player. In addition, a great number of gaming and education sites use Flash and until they implement the HTML5 standards, you’ll need the Flash Player.
Why watch out for Flash updates on Mac?
Adobe is always trying to push its technology further and release the Flash updates to enhance the user experience and security. However, attackers still find the ways to trick you into downloading adware and malware through the popups. That’s why you should know how to protect your Mac against the malicious attacks when you’re trying to update your Adobe Flash for Mac.
Fortunately, it’s easy to make sure that you are installing the real Flash for Mac and are not exposed to the vulnerable software. All you have to do is to be careful and don’t trust the automatic updates.
