This week we discuss some aspects of iOS v11, the emergence of browser hijack cryptocurrency mining, new information about the Equifax hack, Google security research and Gmail improvements, breaking DKIM without breaking it, concerns over many servers in small routers and aging unpatched motherboard EFI firmware, a new privacy leakage bug in IE, a bit of miscellany, some long-awaited closing the loop feedback from our listeners, and a close look at a beautiful piece of work by Moxie & Co on Signal.

We invite you to read our show notes.
