Here’s how: Download CleanMyMac and install it on your Mac. A new piece of Mac-targeted malware has entered the wild, say security researchers with ParetoLogic. Dubbed OSX/Jahlav-C, the software is currently associated with a website called PornTube, and is described as a Trojan concealing itself as an ActiveX object needed to run video. The approach is so.

1. Adobe Flash Player Dmg Virus
2. Mac Media Player Update Virus
3. Downloading Flash Player

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 Its certificate has already been revoked by Apple, but it's good to be aware of your enemies.

Oct 09, 2011 I have tried downloading at least 15 times. I have completely uninstalled version 3 as well and that did nothing to fix it. I have also tried this on both my MacBook Pro and my Mac Pro, both with the same results. Called netflix and they gave me a number to call Microsoft. How to remove 'Adobe Flash Player' is out of date' from Mac? What is 'Adobe Flash Player' is out of date'? When visited, this deceptive website displays a pop-up window suggesting that the version of installed Adobe Flash Player is out of date and encouraging to download, and install the latest one. Malware + Recommended + Security News. Mac Users Attacked Again by Fake Adobe Flash Update. Posted on April 12th, 2016 by Graham Cluley Mac users are once again being urged to exercise caution when installing updates to Adobe Flash Player, after a fake update was discovered infecting computers.

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:

Adobe Flash Player Dmg Virus

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.

1. Launch Finder.
2. Select Applications.
3. Open your Utilities folder.
4. Double-click on Keychain Access.
5. Select the certificate named Adobe Flash Player installer with the signed certificate issued to Addy Symonds.
6. Right or Control + click on the Certificate.
7. Select Delete Certificate from the drop down options.
8. 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. You can protect yourself from attacks if you stay safe.

If you do end up with malware on your Mac, take a moment to relax and know that everything will be O.K. You can remove malware on your own, but if it seems too difficult for you to tackle, you can talk to Apple support. Someone will be able to help you.
