Stopping phone based phishing


Hey Greg, I wanted to write the next piece on the rise of phone based phishing/social engineering. This is an often ignored issue but as we saw with the recent Twitter hack, it can serve as a conduit for social engineering. I am arguing that robocalls undermine the trust users have in cellular companies, a trust which is the reason we use them as the second-factor in 2FA. I am going to offer some solutions as well.
