Your MacBook is your prized possession that holds all your private data, and you want to guard it at all costs. Hackers are infamous for breaking into systems, and as a cautious user, you may wonder whether your Mac is safe. The following is what you should know about your MacBook’s security.
So, can your MacBook get hacked? A MacBook can be hacked by exploiting vulnerabilities that have not been updated with the latest security patches or where Apple have not become aware of a vulnerability and it is being actively exploited like a zero day vulnerability.
Although Apple’s macOS is known for its robust security measures, no system is impervious to cyber threats, and user behavior often determines vulnerability. Phishing attacks, malware, vulnerabilities in macOS to insecure network connections can compromise even the most secure systems. Protecting your MacBook involves regular updates, secure browsing habits, and using trusted security software.
While macOS comes with built-in security features such as Gatekeeper, which restricts the software that can be installed, and XProtect, an invisible antivirus program, these systems are not infallible. Cybercriminals continually find new ways to exploit vulnerabilities, and even the most secure systems can fall victim if users are not vigilant. For example, a user may inadvertently download malware disguised as a legitimate app or click on a phishing link that installs harmful software.
Expanding on the user behavior aspect, it’s essential to consider the role of secure browsing habits and proactive measures. Regularly updating your software ensures you have the latest security patches. Utilizing strong, unique passwords and enabling two-factor authentication adds another layer of protection.
Also, it’s recommended to download apps only from trusted sources like the Mac App Store. Be skeptical of email attachments and links from unknown sources. Finally, consider a reputable third-party antivirus program for an additional security layer.
Apple fortifies all its MacBooks security systems to minimize the chances of being hacked by locking out hackers, making attacks rare. Apple invests heavily in firewalls and anti-virus systems, making hacking challenging and time-consuming. Although there have been some reported cases over the years, Apple can quickly detect and contain any MacBook vulnerabilities.
A hacker can try to infiltrate your MacBook, but the chances are slim, unlike on other devices. One of the most impressive qualities of Apple products is the manufacturers’ focus on making them secure, whether you are using an iPhone, iPad, or iMac. However, hackers often target laptops, and many worry that malicious users can find exploits and leave an open door for data access.
The following vulnerabilities were found in macOS and required Apple to quickly create and deliver security patches:
- Gatekeeper Bypass Vulnerability (CVE-2019-1457)
- Zoom Vulnerability
- KeySteal Daemon
- Root Bug Vulnerability (CVE-2017-13872)
- Thunderstrike and Thunderstrike 2 (CVE-2014-4498)
- ShellShock (Bash bug) (CVE-2014-6271, CVE-2014-7169)
The Gatekeeper Bypass Vulnerability allowed malicious applications to bypass Apple’s Gatekeeper security feature, which is designed to ensure only trusted software is run on Mac systems. It was discovered by a security researcher and patched by Apple in late 2019.
The Zoom Vulnerability in the Zoom video conferencing app for MacOS was discovered that allowed any website to forcibly join a user to a Zoom call, with their video camera activated, without the user’s permission.
The KeySteal Daemon allowed attackers to steal passwords from a Mac’s keychain without needing admin access. It could potentially give attackers access to online account logins, credit card information, and other sensitive information.
The Root Bug Vulnerability was discovered that allowed anyone to gain root access to a MacOS system by entering “root” as the username with no password in the system preferences panel. This was a serious vulnerability that was quickly patched by Apple.
The Thunderstrike and Thunderstrike 2 vulnerabilities were discovered in 2014 and could allow attackers to infect Apple’s EFI (Extensible Firmware Interface) boot ROM through the Thunderbolt ports.
The ShellShock (Bash bug) was a serious vulnerability that affected Unix-based systems, including MacOS. It allowed an attacker to execute commands on an affected system.
The MacBook is not immune to hacking, but unlike other PC operating systems, the chances are relatively lower. Apple works tirelessly to prevent this from happening, explaining why the attacks are rare.
The T1 and T2 chips and Apple’s anti-virus techniques effectively shut out hackers due to the hassle involved. However, there have been some confirmed cases over the years, although Apple usually steps in swiftly to patch all the vulnerabilities before exploitation.
Apple is famous for its dedication to protecting users and their devices, as you can tell by the lengths it goes to make hacking challenging. One of the working technologies that Apple uses in MacOS is the Gatekeeper.
Its principle is to verify applications before the system downloads them, ensuring that the MacBook only runs legitimate software. It reduces the chances of unknowingly introducing malware to the device.
Additionally, Apple has an in-built XProtect, and the T1 and T2 chips have heightened security. With such firewalls, the chances of hacking are slim since, even brilliant attackers would consider the process too tasking.
On the downside, the Mac is still vulnerable to hacking, although not as much as other operating systems. Once in a while, experts identify some loopholes that hackers can use, known as 0-day vulnerabilities or back doors.
The security personnel in Apple work relentlessly to identify any loophole and inform Apple for another team to seal the vulnerabilities. Luckily, they rarely occur, but Apple must work fast before attackers use them to their advantage and access your Mac.
One way to restore security is by releasing operating system updates, which users must accept to keep their MacBook secure.
Therefore, always updating your software whenever updates are available is essential. For instance, updates helped Apple solve some vulnerabilities that made headlines in 2018.
Apple rapidly resolved the “Specter” and “Meltdown” in the Mac processors through system enhancements before they could affect users. The experts immediately patched the holes and restored Mac’s security. Another frequently asked question about Macs is how secure the camera is.
Since 2019, with the release of macOS Catalina, Apple has ascertained that the MacBook’s camera is secure. The users are safe from related attacks because Apple included the permission feature before screen recording or running a video or mic.
Also, you will see a green flash next to the camera whenever it is operating. Besides infiltrating the system to obtain sensitive data, the camera is another lucrative avenue for attackers.
There are various ways for hackers to obtain personal information once a backdoor is used without your consent. Moreover, a malicious user can install a system that detects the keys you enter into your MacBook and record the buttons you need for your password while at it.
Therefore, when in contact with your computer, it will be effortless to gain access. Another risk is that they can use spyware to take control of your video and microphone, listening to and watching everything you do.
Fortunately, the Catalina update helped seal such vulnerabilities. On the contrary, there were some reported issues with Zoom where attackers resorted to including users in calls without their consent and turning on their cameras.
However, Apple solved this issue, and there are no such cases anymore. Ultimately, Apple may invest heavily in sealing all the cracks, but sometimes hackers still find a way to infiltrate.
It is best to know the possible forms of attacks on your MacBook to stay safe.
