Last week we listed the top 10 mobile security blogs that have made an impact on our security best practices and I’m sure to yours as well. Over the last few years, we have seen an alarming increase in security breaches that has changed the way we look at cyber security. The total number of data records compromised from the high-profile breaches of 2015 amounted to more than 175 million records.

I’m an avid security enthusiast who has been constantly keeping a tab on the latest things happening in the security space. This week I want to share my list of the top 17 mobile security experts who have and still are making significant impacts to the cyber security ecosystem.

Recently, he and his fellow cybersecurity researcher Collin Mulliner claimed that every iPhone in this world can be hijacked by sending one simple message. He wrote a book with Dino Dai Zovi “The Mac Hacker’s Handbook” and I recommend you to read his book, if you want your MAC OS to be secured in a better way. Regardless of what people think, Charlie tops my list of mobile security experts.People make money by building new things, and the faster they can do it, the better @0xcharlie Click To Tweet
