If you’re a Mac user, it’s important to be aware of the growing number of ransomware attacks that are specifically targeting macOS devices. Just like Windows users, you need to take precautions to protect yourself from these threats. Here’s how you can secure your Mac against ransomware attacks.

Defining ransomware

Ransomware is a type of malicious software, or malware, designed to extort money from victims. It works by locking down access to an infected computer’s system and files and demanding payment, typically in a cryptocurrency such as Bitcoin, in return for unlocking the system.

Mac ransomware wreaking havoc

There is a common misconception that Macs are safe from ransomware. But as some recent ransomware attacks show, Macs are no safer than Windows computers from the growing threat of ransomware.

In 2016, a ransomware named KeRanger made waves when it was found to have affected over 7,000 macOS computers. KeRanger managed to bypass Apple’s renowned security protocols by piggybacking on an official BitTorrent client called Transmission.

Meanwhile, in 2017, another ransomware strain targeting Mac was discovered. Called Patcher, this Mac ransomware was disguised as an application for patching programs like Microsoft Office. However, launching Patcher would encrypt user directories and demand payment for a decryption key that would never be provided due to the software’s faulty construction.

And finally, in 2019, the EvilQuest ransomware ran rampant on Mac computers around the world. Even after paying the ransom, EvilQuest victims weren’t able to gain back access to their systems and files

Prevention is key

Taking proactive steps to prevent ransomware from occurring is the best defense you can have. You can start by ensuring that your Mac’s operating system (OS) and applications are updated on a regular basis. Aside from improved system performance, OS updates usually include essential security patches that aim to address the latest security threats.

And to ensure that your data remains safe, perform regular backups and set up firewalls and antivirus software on your Mac. Doing so can significantly reduce the risk of unauthorized access or exposure to damaging malware. Additionally, creating backups can also help you recover important files in the event of a ransomware attack or any other untoward event.

Another essential security tip is to use strong passwords and multifactor authentication (MFA) whenever possible. These security methods can provide an added layer of protection to your data and systems, making it difficult for attackers to gain access to confidential information.

Furthermore, it is important to stay vigilant and aware of phishing emails since these are the most common delivery method for ransomware. If you receive an email from someone you don’t know, or an email you weren’t expecting, avoid clicking on suspicious links or attachments.

What to do in case your Mac gets infected

If you find yourself in the unfortunate situation of having your Mac infected with ransomware, take these steps to protect your data, restore access to files, and remove the malware from your device.

  1. Immediately disconnect from the internet or disable any form of wireless connection to contain the spread of the ransomware.
  2. After that, if possible, back up all of your important files and folders onto an external drive or file storage provider. Make sure not to include any encrypted files in this backup.
  3. Run an antivirus scan on your Mac and delete any detected threats.
  4. Reinstall any deleted apps or replace corrupted system files.
  5. Finally, connect to the internet again and check whether ransomware is still present on your Mac.

It’s also crucial to not pay the ransom fee. Paying the ransom does not guarantee that the attackers will provide you with the decryption key to release your data. Instead, you may explore free ransomware decryption tools online to remove the ransomware from your Mac.

Lastly, with a severe threat like this, it’s best to work with cybersecurity experts. They know all about the latest Mac security threats and will be able to best assess and address the situation, and take the necessary steps to keep your organization safe.

Windows users are often the victims of ransomware attacks. For example, in 2017, WannaCry and Petya ransomware infected hundreds of thousands of Windows PCs around the world. Unfortunately, ransomware strains that specifically target Macs are expected to grow in number as well. If you have a Mac, follow the security best practices below to avoid getting infected.

What is ransomware?

Ransomware is a type of malicious software that holds computer systems hostage via encryption until a ransom is paid. Attackers typically threaten to release the encrypted information to the public or destroy sensitive data if victims don’t pay within a certain deadline. Healthcare and finance organizations, in particular, are more likely to pay the ransom because these organizations tend to be worth a lot of money and have many valuable assets, and can’t afford to lose access to their critical data.

As its name suggests, Mac ransomware is simply ransomware that targets Mac desktops and laptops. And just like other types of ransomware, it is typically distributed via phishing emails.

Types of Mac ransomware

In 2016, the KeRanger ransomware was distributed through the popular BitTorrent app Transmission. KeRanger was signed with an authorized security certificate, allowing it to evade macOS’s built-in security measures and infect more than 7,000 Mac computers.

Meanwhile, the Mac ransomware strain Patcher was discovered in 2017. It disguised itself as a patching app for programs like Microsoft Office. When launched, Patcher would encrypt files in user directories and ask for a Bitcoin ransom. But the ransomware was poorly built, so there was no way to retrieve the decryption key once the ransom was paid.

In 2019, the EvilQuest ransomware encrypted files and forced victims into paying a Bitcoin ransom. Much like Patcher, however, there was no decryption key, leaving those who paid the ransom with nothing.

Ransomware attacks like these can make a resurgence at any time, which is why you need to be prepared in case of an attack.

An ounce of prevention goes a long way

Preventive measures are the best way to keep your Macs safe from ransomware. This involves installing only programs from the official App Store and the latest software patches to defend against the latest threats.

Since phishing emails are the usual delivery method of ransomware, be wary of suspicious links and email attachments. Always be on alert even if the email appears to come from a legitimate company or someone you know.

You must also maintain offline backups and have a disaster recovery plan to keep your business running in the event that ransomware successfully infiltrates your systems.

Responding to ransomware

If your Mac is infected with ransomware, do not pay the ransom fee, as there’s no guarantee that hackers will provide a decryption key and release your data. Instead, use an up-to-date anti-malware program to remove ransomware from your computer. There are also free ransomware decryption tools online that you can use to remove the infection.

If these tools don’t work, contain the spread of the ransomware by disconnecting from the network. Afterwards, run data recovery procedures and immediately seek the help of our cybersecurity experts. We stay abreast of the latest Mac security threats and know just how to keep your business safe.

Although a majority of ransomware attacks usually target Windows PCs, this doesn’t mean Mac users are completely safe. Ransomware attacks for Macs have occurred before, and are growing more widespread over time. So how can you prevent ransomware from infecting your Mac? We’ve compiled some helpful security tips for you.

What is Mac ransomware?

Ransomware is a type of malicious software that holds computer systems hostage until a ransom is paid in gift cards, or cryptocurrency like Bitcoin or Ethereum. It’s typically distributed using phishing emails, but it can also spread via unsecured networks.

When Macs are infected by ransomware, users won’t be able to access their data since it’s encrypted. Ransomware messages may also threaten to release the information to the public or destroy sensitive data if victims don’t pay within a certain deadline. Healthcare and finance organizations, in particular, are more likely to pay the ransom because these organizations tend to have a lot of valuable assets, including money, and can’t afford to lose access to their critical data.

Types of Mac ransomware

In 2016, the KeRanger ransomware was distributed through the popular BitTorrent app Transmission. KeRanger was signed with an authorized security certificate, allowing it to evade macOS’s built-in security measures and infect more than 7,000 Mac computers.

Patcher was another strain of Mac ransomware that was discovered in 2017. This type of ransomware disguised itself as a patching app for programs like Microsoft Office.

You must also maintain offline backups and have a disaster recovery plan to keep your business running in the off chance that ransomware successfully infiltrates your systems.

Responding to ransomware

If your Mac is infected with ransomware, do not pay the ransom fee, as there’s no guarantee that hackers will provide a decryption key and release your data even if you give in to their demands.

Instead, use an up-to-date anti-malware program to remove ransomware from your computer. Cybersecurity experts may also release free ransomware decryptor tools to remove the infection, so keep an eye out for these on the internet. If these programs and tools don’t work, contain the spread of the ransomware by disconnecting from the network and run data recovery procedures, provided you’ve backed up your data in an external hard drive or the cloud.
