Beware scams in the wake of the App Store slip-up

Posted on November 13th, 2015 at 3:17 PM EST

Mac users began to have problems opening apps downloaded from the App Store Wednesday morning. This caused messages that the apps were damaged and would need to be re-downloaded from the App Store.

It turned out that the problem was an expired cryptographic certificate at Apple, used to verify the legitimacy of these apps. Apple didn’t renew it in time, and when it expired, App Store apps failed.

Last week, Bit9 + Carbon Black released a paper stating that five times more malware for OS X has appeared in 2015 than during the previous five years combined.

Introducing Malwarebytes Anti-Malware for Mac

Posted on July 15th, 2015 at 10:09 AM EST

As faithful readers will know, my name is Thomas Reed, and I have been the sole owner of The Safe Mac and creator of the anti-adware program AdwareMedic for a few years now.

In March, I was contacted by Marcin Kleczynski, CEO of Malwarebytes, who expressed interest in the things I had been doing. The timing could not have been better, and I’m pleased to say that AdwareMedic and The Safe Mac are now owned by Malwarebytes, and I’m now the Director of Mac Offerings at Malwarebytes. Given the Malwarebytes philosophy of taking a hard stance against adware and PUPs (Potentially Unwanted Programs), and their commitment to offering free consumer versions of their products, the fit could not have been any better!

I’m excited to announce that, today, we’re rolling out our flagship Mac product: Malwarebytes Anti-Malware for Mac. This is an improved, but still largely familiar, update of AdwareMedic, and it will be free for all consumers. I’m even more excited when I think about plans for the future, which will include rounding out Malwarebytes’ offerings with other Mac products, providing features like efficient real-time protection, anti-exploit protection and enterprise-friendly capabilities.

I think that, together with Malwarebytes, we can make Mac anti-malware software better, and that’s going to be important in the years ahead!

I will also be continuing to write about Mac security issues, as part of a team of other great, award-winning writers, on the Malwarebytes Unpacked blog. Although I won’t be posting new content on The Safe Mac, it won’t be going away; it’s just changing form.

I’m looking forward to working with Malwarebytes to protect and educate Mac users. I hope you’ll join us!
