Hey Mac Users: Get Your Guard Up!
There was a recent news article about a 28-year-old man who allegedly hacked into thousands of computers. Federal prosecutors say he created malware that enabled him to remotely access and turn on the cameras and microphones of the computers.
His malware program is named Fruitfly. It was found in both PCs and Macs. The article reported that many cybersecurity researchers were surprised it was on so many Macs. Why surprised? Because there are far more Windows PCs in the world, so most hackers don't target Macs.
However, as I and my other tech colleagues on island well know, there is plenty of malware out there aimed at Macs. We've seen it and removed it.
The cited article reports a 270 percent increase last year in new strains of malware for Macs.
So what can Mac users do to better protect their systems? Here are some suggestions, most of which pertain to Windows PCs too.
- The primary shield is you. Be careful which sites you visit, which links you click, who you let on your computer, which programs you install, etc.
- Back up all important data frequently, preferably online. For local backup to external hard drive you can use Time Machine. For online backup I recommend Mozy.com (it's free for up to 2 GB backup).
- Make sure to install all Apple updates when they're issued.
- Create an admin account, password protect it, and demote your usual account to standard user level, and password protect it.
- Install anti-malware software. A good free program is Bitdefender, or Malwarebytes. For a paid program, I recommend ESET Cyber Security. If you suspect you're already infected, you can run a scan with the free Malwarebytes program, then download, install, and scan with Bitdefender or ESET as well. [disclosure: I'm reseller of ESET]
- Make sure you are behind a hardware firewall on your network and update it. (This usually means your router.)
- Enable the Mac OS X firewall.
- If you have children using a Mac, enable Parental Controls.
- If you're a mobile professional (using a MacBook) I suggest enabling FileVault, which encrypts your files. And enable Find My Mac.
- Keep up with Mac-specific security news.

The Myth of the Impervious Mac
What's the issue?
Conventional thinking in computer user land - and rightly so for awhile now - is that Macs are unlikely to be infected by viruses.
That thinking must now change.
I can attest to working on four infected Macs in the last week prior to writing this article (June 2015). Mac users must start being more Internet-security savvy and protect their computers with security software and best practices.
Why is this happening?
The infections I cleaned up targeted browser weak points and/or enticed the users to download software - social networking type of exploits.
In one case the client I helped had downloaded software that launched a webpage prompting her to call a number for tech support. When someone with a thick foreign accent at a call center answered, she was immediately suspicious. When that person asked to remotely connect to her computer, she hung up. Then she called for our help to remove the infection.
Another client was not so fortunate. She fell for the scam and allowed them remote access to her computer. After she realized the danger and disconnected the remote tech, she called us. I removed 51 infections on her Mac, including some Trojan viruses.
How to not fall victim to tech support scams?
In one of my previous blog posts, linked here, I explained how to be careful about requesting computer tech support. Be suspicious of anyone offering tech support online or calling you. And be very careful about downloading software on your computer. When in doubt, don't do it, or at least spend some time researching it.
I recommend taking these protective measures on your Mac:
- Back up all important data at once and do so frequently.
- Make sure you have all Apple updates installed, and keep up with doing this.
- Try using Firefox instead of Safari and keep it updated.
- Create an admin account on your Mac, password protect it, then demote your usual account to standard user level and password protect it.
- Install an antivirus program like Sophos, Avast, or AVG and scan you entire Mac; do the scan weekly, or at least monthly.
- Make sure you are behind a hardware firewall in your home or business network.
- Keep up with Mac-specific security news.
Here are some additional Mac-specific security tips, which are a little more techie, such as enabling the Firewall and turning on Vault (to encrypt).
In Sum
Sorry to say it, but Mac users can no longer relax in thinking that Windows systems are the focal point for hackers. It's open season on everyone now. Be careful, and protect yourself the best you can. It's all we can really do, except for limiting computer use on the Internet, which of course, is an option given how much we use our smartphones these days for web and email. I wrote on this subject in this blog post.
Update 5/27/16... here's a post that references the hows and whys of Mac infections...
