Spyware for mac pro#
And buying that latest MacBook Pro on a Black Friday deal would mean nothing in an instant. With all the intelligence around us today, literally any time you might be hit with the next cyber-attack. Just because Apple has an iron grip-type security status, it doesn’t mean hackers or scammers cannot break into it. Last year, Wardle, working with security researcher Peter Dantini, found a sample of Shlayer that had been accidentally notarized by Apple, a process where developers submit their apps to Apple for security checks so the apps can run on millions of Macs unhindered.Security is probably the last element we think of investing in when it comes to having a Mac.īelieve it or not: Just like Windows, Apple is as much prone to having malware or viruses. It’s not the first time Shlayer has evaded macOS’ defenses. Wardle has also published a Python script that will help users detect any past exploitation. “The most interesting thing about this variant is that the author has taken an old version of it and modified it slightly in order to bypass security features on macOS,” said Bradley. “The version of Shlayer that uses this technique does so to evade built-in malware scanning, and to launch without additional ‘Are you sure’ prompts to the user,” he said. “It’s often installed by tricking users into downloading fake application installers or updaters,” said Bradley. Shlayer is an adware that intercepts encrypted web traffic - including HTTPS-enabled sites - and injects its own ads, making fraudulent ad money for the operators. Further analysis leads us to believe that the developers of the malware discovered the zero-day and adjusted their malware to use it, in early 2021.”
“One of our detections alerted us to this new variant, and upon closer inspection we discovered its use of this bypass to allow it to be installed without an end user prompt. Shlayer is known to be one of the most abundant pieces of malware on macOS so we’ve developed a variety of detections for its many variants, and we closely track its evolution,” Bradley told TechCrunch. “The malware we uncovered using this technique is an updated version of Shlayer, a family of malware that was first discovered in 2018. Jamf also published a technical blog post about the malware. Jamf detections lead Jaron Bradley confirmed that a sample of the Shlayer malware family exploiting the bug was captured in early January, several months prior to Owens’ discovery.

With knowledge of how the bug works, Wardle asked Mac security company Jamf to see if there was any evidence that the bug had been exploited prior to Owens’ discovery.

“The update will now result in the correct classification of applications as bundles and ensure that untrusted, unnotarized applications will (yet again) be blocked, and thus the user protected,” he told TechCrunch.
Wardle described the bug as rendering macOS’ security features as “wholly moot.” He confirmed that Apple’s security updates have fixed the bug.

But Owens found that taking out this property file and building the bundle with a particular structure could trick macOS into opening the bundle - and running the code inside - without triggering any warnings. In simple terms, macOS apps aren’t a single file but a bundle of different files that the app needs to work, including a property list file that tells the application where the files it depends on are located. The bug meant that macOS was misclassifying certain app bundles and skipping security checks, allowing Owens’ proof-of-concept app to run unimpeded.
In a technical blog post today, Wardle explained that the vulnerability triggers due to a logic bug in macOS’ underlying code. Owens asked Mac security researcher Patrick Wardle to investigate how - and why - the bug works. Apple also patched earlier macOS versions to prevent abuse, and pushed out updated rules to XProtect, macOS’ in-built anti-malware engine, to block malware from exploiting the vulnerability.

The proof-of-concept app disguised as a harmless document running on an unpatched macOS machine.
