BUG BOY Mac OS
Increased security
The first day Kroc's cash register rang up $366.12. Today the company racks up about $50 million a day in sales in more than 12,000 outlets worldwide, and for the past ten years a new store has opened somewhere around the world an average of every fifteen hours. The double-decker Big Mac was introduced in 1968, the brain-child of a local. Mouthwatering perfection starts with two 100% pure beef patties and Big Mac® sauce sandwiched between a sesame seed bun. It’s topped off with pickles, crisp shredded lettuce, finely chopped onion and American cheese for a 100% beef burger with a taste like no other.
McDonald's family of Big Mac sandwiches is growing with two new additions. Feedback Assistant for Developers. Developer feedback is vital to making the Apple ecosystem even better. With Feedback Assistant available on iPhone, iPad, Mac, and the web, it’s easy to submit effective bug reports and request enhancements to APIs and tools. In Apple’s early days, their laptops were often a tough sell, because many Windows-only programs didn’t have functional equivalents for the Apple OS X operating system. But now that most software is web-based, and most developers have Mac-friendly versions of their applications, MacBooks are for everyone.
High Sierra is an update of MacOS which focuses mostly on back-end developments and a higher level of user security. As such, this operating system lays a foundation for future upgrades.
Stay safe
In essence, High Sierra took what was good with Sierra and developed it into a more comprehensive software.
High Sierra emphasizes the already-existing benefits of MacOS previous system, Sierra. There are few bells and whistles, but the changes are noticeable and positive. The Apple file system is the most significant feature it brought. It enables the storage and encryption of a large number of files. Thus, it boosts performance and helps manage device memory issues.
Apple also introduced new formats for video and photos in this version. These formats compress data - that’s a benefit as files can get huge with ever-rising resolutions. They added support for virtual reality headsets as well.
Besides that, when it comes to Safari, Mac search engine, there are some notable improvements with the update. The users can now control annoying auto-play videos, prevent tracking, and more. There are also notification controls, and you will experience a boost in performance, too.
The most noticeable changes took place in Apple’s Photo App, though. It went through a total revamp both visually in its interface and terms of tools and functions available. Many other discreet changes happened all over the system.
Where can you run this program?
If you’re running Sierra on your Mac, you will be able to run this one as well.
Is there a better alternative?
Yes. Mojave, the newest version of MacOS, brought even more improved features to the table. However, if you can’t run it on your device, this is the second best.
Our take
High Sierra is not the shiniest upgrade Apple brought, but it’s one that sets the stage for new upgrades to come. Even out of that context, it’s a great operating system.
Should you download it?
Yes, if your device can support it. The new options and better security settings are worth getting.
Highs
- Improved storage
- Smaller image and video sizes
- Handy Safari updates
- Upgraded security
Lows
- Apps require updates for compatibility
- Siri produces questionable results

Apple has fixed a zero-day vulnerability in macOS exploited in the wild by Shlayer malware to bypass Apple's File Quarantine, Gatekeeper, and Notarization security checks and download second-stage malicious payloads.
Shlayer's creators have managed to get their malicious payloads through Apple's automated notarizing process before.
If they pass this automated security check, macOS apps are allowed by Gatekeeper—a macOS security feature that verifies if downloaded apps have been checked for known malicious content—to run on the system.
In the past, Shlayer also used a two-year-old technique to escalate privileges and disable macOS' Gatekeeper to run unsigned second-stage payloads in a campaign detected by Carbon Black’s Threat Analysis Unit.
Zero-day exploited in the wild to deploy malware
The Jamf Protect detection team discovered that starting January 2021, the Shlayer threat actors created unsigned and unnotarized Shlayer samples have begun exploiting a zero-day vulnerability (tracked as CVE-2021-30657), discovered and reported to Apple by security engineer Cedric Owens.
As revealed by security researcher Patrick Wardle, this now fixed bug takes advantage of a logic flaw in the way Gatekeeper checked if app bundles were notarized to run on fully-patched macOS systems.
Wardle added that 'this flaw can result in the misclassification of certain applications, and thus would cause the policy engine to skip essential security logic such as alerting the user and blocking the untrusted application.'
Unlike previous variants that required victims to right-click and then open the installer script, recent malware variants abusing this zero-day and distributed using poisoned search engine results and compromised websites can be launched by double-clicking.
Today, Apple has released a security update to fix the vulnerability in macOS Big Sur 11.3 and block malware campaigns actively abusing it.
Users are now alerted that malicious apps 'cannot be opened because the developer cannot be identified' and advised to eject the mounted disk image because it may contain malware.
The Shlayer macOS malware
Shlayer is a multi-stage trojan that attacked over 10% of all Macs, according to a Kaspersky report from January 2020.
Intego's research team spotted Shlayer for the first time in a malware campaign in February 2018, camouflaged as a fake Adobe Flash Player installer just as many other malware families targeting macOS users.
Bug Boy Mac Os Update
Unlike original variants, which were pushed via torrent sites, new Shlayer samples are now spread via fake update pop-ups shown on hijacked domains or clones of legitimate sites, or in far-reaching malvertising campaigns plaguing legitimate websites.
After infecting a Mac, Shlayer installs the mitmdump proxy software and a trusted certificate to analyze and modify HTTPS traffic, allowing it to monitor the victims' browser traffic or inject ads and malicious scripts in visited sites.
Even worse, this technique allows the malware to alter encrypted traffic, such as online banking and secure email.
While Shlayer's creators currently only deploy only adware as a secondary payload, they can quickly switch to more dangerous payloads such as ransomware or wipers at any time.
One more zero-day exploited in the wild fixed today
Today, the company another WebKit Storage zero-day bug exploited in the wild, tracked as CVE-2021-30661, and impacting iOS and watchOS devices by improving memory management.
The vulnerability allows attackers to execute arbitrary code after tricking targets into opening a maliciously crafted website on their devices.
The list of affected devices includes those running:
- Apple Watch Series 3 and later
- iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation)
Bug Boy Mac Os X
In total, with today's security updates for macOS and iOS bugs exploited in the wild, Apple has addressed nine zero-days since November.
The company patched three other iOS zero-days—a remote code execution bug (CVE-2020-27930), a kernel memory leak (CVE-2020-27950), and a kernel privilege escalation flaw (CVE-2020-27932)—affecting iPhone, iPad, and iPod devices in November.
In January, Apple fixed a race condition bug in the iOS kernel (tracked as CVE-2021-1782) and two WebKit security flaws (tracked as CVE-2021-1870 and CVE-2021-1871).
