Can malware affect your Mac?

Malware creators will target anyone and everyone, including Mac users. So even though Apple computers are less vulnerable than Windows PCs, they are not completely impervious to cyberattacks. Read on to find out the different threats you should protect your Mac against, as well as signs that your computer has been compromised.

What are the threats that can affect your Mac?

There are several forms of malware that hit Apple products, and their effects can range from ones that are merely annoying to downright destructive.

  1. Adware – These are unwanted programs that bombard users with pop-up advertisements. Some malicious adware piggyback spyware like keyloggers and keyboard sniffers onto their deployment protocols, allowing them to record your typing habits and monitor your browsing behavior.
  2. Sniffers – These are usually designed to detect certain words on a web page and in a person’s typing pattern in order to trigger the keylogger. For instance, when you type your password, sniffers can activate the keylogger to copy the information you type and steal your login details.
  3. Trojan horses – These can infect both Macs and PCs, and they are often deployed through fake software installers or unsecured updates. They parade as legitimate software that actually contain a nasty surprise once installed. A notorious Trojan horse for Macs is the MacDownloader, which attempts to steal personal data stored in iCloud Keychain.
  4. Macro viruses – These attack computers by running a code that can take screenshots, format hard drives, corrupt files, deliver more malware, and access webcams and microphones. They are triggered when a user opens an infected macros-enabled file, hence the name.
  5. Ransomware – Macs managed to hold off ransomware for a while, but nowadays, even they can be vulnerable to it. KeRanger was one of the first big ransomware outbreaks in Macs. After remotely encrypting the computer and hibernating for three days, KeRanger would issue a .txt file containing instructions for decryption in return for one bitcoin.

Telltale signs your Mac is infected

Now that you know what kinds of malware your Mac could be affected with, here are some ways to tell if your computer is infected with one:

  1. Pop-up ads – If you’re seeing more pop-ups on your computer than usual, your computer is probably infected. An unusual amount of banner ads and pop-ups may mean that your computer is due for an update and/or a virus scan.
  2. Slowness – Mac users fear one thing above all: the spinning wheel of death. This little rainbow-colored spinning cursor wheel indicates that the computer is having trouble processing at usual speeds. This slowness can often be caused by overwhelming requests from simultaneous processes — likely of dubious origin — running in the background.
  3. Browser issues – Viruses sometimes do weird things to Safari or Google Chrome such as change its homepage or redirect a preset landing page to a site you’ve never seen before. If your browser starts behaving oddly, crashes regularly, or is often unresponsive, your Mac might have a virus.

Computer security is a matter of importance no matter what operating system you use. Reach out to our experts for an assessment of your network today.

Cybersecurity terminology you need to know

Do IT security terms like “phishing” and “intrusion protection” sound extremely foreign to you? If so, it’s time you familiarize yourself with these and other common cybersecurity terms. By learning these basic concepts, you’ll be more aware of the depth and scope of online dangers and, hopefully, be better prepared to deal with them.

Malware

For a long time, the phrase “computer virus” was misused to refer to every type of attack that intended to harm or hurt computers and networks. The more appropriate term for these harmful programs and files would be "malicious software" or "malware." Whereas a virus is a specific type of malware that is designed to replicate itself, any software created for the purpose of destroying or unfairly accessing networks and data should be referred to as malware.

Ransomware

Don't let all other cyberthreats ending in -ware confuse you; they are all just subcategories of malware. Currently, one of the most popular of these is “ransomware,” which is malware that encrypts valuable data until a ransom is paid.

Intrusion prevention system (IPS)

There are several ways to safeguard your network from malware, but an IPS is quickly becoming one of the nonnegotiables. An IPS sits inside your company’s firewall and looks for suspicious and malicious activity that can be halted before it can exploit or take advantage of a known vulnerability.

Social engineering

Not all types of malware rely solely on fancy computer programming. Experts agree that the majority of attacks require some form of “social engineering” to succeed. Social engineering is the act of tricking people, rather than computers, into revealing sensitive or protected information. For cybercriminals, complicated software is totally unnecessary if they can just convince potential victims that they’re a security professional who needs the victims’ password to secure their account.

Phishing

Despite often relying on face-to-face interactions, social engineering does occasionally employ more technical methods. Phishing is the act of defrauding people using an app or a website that impersonates a trustworthy or often well-known business in an attempt to obtain confidential information. Just because you received an email that says it’s from the IRS doesn’t mean that it is. Don’t take such emails at face value — always verify the source, especially if the emails are requesting your sensitive data.

Antivirus

Antivirus software is often misunderstood as a way to comprehensively secure your computers and workstations. These applications are just one piece of the cybersecurity puzzle and can only scan the drives on which they are installed for signs of well-known malware variants.

Zero-day attacks

Malware is most dangerous when it has been released but not yet discovered by cybersecurity experts. When a vulnerability is found within a piece of software, vendors will release an update to fix the gap in security. However, if cyberattackers release a piece of malware that has never been seen before, and if that malware exploits one of these holes before the vulnerability is addressed, it is called a zero-day attack.

Patch

When software developers discover a security vulnerability in their programming, they usually release a small file to update and “patch” this gap. Patches are essential to keeping your network secure from the vultures lurking on the internet. By checking for and installing patches as often as possible, you keep your software protected from the latest malware.

Redundant data

When antivirus software, patches, and intrusion prevention fail to keep your information secure, there’s only one thing that will: quarantined off-site storage. Duplicating your data offline and storing it somewhere other than your business’s workspace ensures that if there is a malware infection, you’re equipped with backups.

Keep ransomware out of your Android device with these tips

More and more organizations are using mobile devices to conduct various business processes, from staying in touch with customers and partners to performing financial transactions. This fact is not lost on cybercriminals — they’re launching ransomware to get into Android devices and hold the data on these devices hostage in exchange for large sums of money. Learn more about mobile ransomware and its risks, as well as some ways by which you can defend against it.

How does mobile ransomware work?

Android users may unwittingly download mobile apps riddled with ransomware from third-party app stores or even legitimate ones such as Google Play Store. Once these apps are installed, the ransomware is launched, locking the device and encrypting the data it contains. The victim may see a ransom note on the screen demanding payment in Bitcoin or some other cryptocurrency in exchange for unlocking the device or the decryption key.

One specific ransomware strain detected in late 2020 locks a mobile device’s screen and prevents the user from dismissing the ransom note, which looks like a message from the police. The note tells the user that they committed a crime and must pay a fine — a technique that cybercriminals have been using to make their victims panic, making the latter more likely to pay up.

What should you do if your Android device is infected?

Just as with ransomware that affects computers, there’s no guarantee that paying the ransom will restore access to the device and/or encrypted data. This is why cybersecurity and law enforcement professionals advise against giving in to cybercriminals’ demands.

Instead, they recommend that you immediately disconnect the infected smartphone or tablet from your business’s Wi-Fi or home network and other devices it’s connected to. This will prevent further infections within your network.

Next, report the incident to your in-house IT staff or managed services provider, who can help you find out what type of ransomware you’re dealing with. They can then figure out the best way to remove the ransomware and help you regain control of your device and everything in it.

How do you protect your business from mobile ransomware?

Remind your employees to download from official app stores only; they should never download from third-party app stores and websites, as well as online forums. Additionally, make sure they turn on Google’s security system, Verify Apps, which scans apps for potential threats before these can be installed. They can do this on their Android devices by going to Settings > Security > Verify Apps, and enabling “Scan device for security threats.”

Also, ensure that all your employees’ mobile devices have antivirus software installed on them, and that it’s always kept up to date.

Finally, back up important files on mobile devices to either a USB drive, a computer, or any cloud-based storage service. This way, your staff won’t lose valuable data if they need to reset their smartphone or tablet.

Configuring Windows 10 on your laptop

If you just bought a new laptop, then it probably has Microsoft’s Windows 10 operating system pre-installed. Windows 10 is packed with some interesting features you can fully maximize by following these tips.

1. Set up how your device checks for updates

Your new laptop should check for updates automatically, but you can also do this manually. Just click the gear icon above the Start button to go to Settings, choose Update & Security > Windows Update, and then click Check for updates. You can also type “updates” into the search box and click Check for updates.

2. Choose a restore point

If something goes wrong with your laptop, you can save a lot of time if you have a restore point, which is a backup of your entire operating system. To set up a restore point, type "restore" into the search bar and click Create a restore point. You’ll be taken to the System Protection tab of the System Properties window.

From there, you can choose what you want to be included in the backup. Click the Configure button to apply your choices. Enable “Turn on system protection” if it’s not already on. You can choose how much disk space to reserve, usually no more than 2% or 3%.

3. Pick a power plan

If you want to prolong your laptop’s battery life, you can choose from Windows 10’s Power Saver, High Performance, and Balanced power plans. Type power plan in the search button and choose either “Edit power plan” or “Choose a power plan.” Choosing the Edit power plan option allows you to set when the laptop display will be automatically turned off and when to put it to sleep. When you pick “Choose a power plan,” it will take you to a page where you can create and customize your plan.

The default recommended plan is Balanced, but if you want to create your own, click on the "Create a power plan" option on the left part of the screen. You can choose from three options depending on how you plan to use your laptop: Balanced, Power Saver, and High Performance. After selecting your preferred plan, click on the Next button to set the display and sleep settings for your laptop. Once done, click on the Create button and you're good to go.

4. App installation tolerance level

To restrict which apps can be installed on your laptop, go to Settings > Apps > Apps & features and choose whether to permit installations from only the Windows Store, any app installations (with a warning), or unrestricted app installations.

5. Remove bloatware

Vendors package new laptops with bundled apps and software, which are mostly unnecessary and unwanted programs called bloatware.

Windows 10 offers an easy way to see which apps are installed on your new laptop and a quick way to uninstall those you don’t need. Head to Settings > Apps > Apps & features and peruse the list. If you don’t want an app and are 100% certain that your computer doesn’t need it, click the Uninstall button.

6. Anti-ransomware

Ransomware is a form of malicious software (malware) that locks all your data until you pay a ransom to hackers.

To minimize the risk of ransomware attacks, type “Windows Security” into the search bar at the bottom of your screen, click it, and go to “Virus & threat protection”. Here, you’ll be able to enable a new option called “Controlled folder access,” which protects you against ransomware attacks. By default, the Desktop, Documents, Music, Pictures, and Videos folders are protected, but you can add other folders too.

There are myriad ways Windows 10 can be configured for optimization and security. This article barely scratches the surface of Window 10’s security and efficiency settings. Call us today for a quick chat with one of our Microsoft experts about taking your operating system to the next level.
