  • Pieces0310 also shows how he bypasses a Win10 logon password using Lazesoft’s Recover My Password. I can’t recall if I figured out a way around the Win10 LiveID passwords, might have to put that on the research list. If anyone has a way to extract the cached password/hash then let me know.

  • On this week’s Digital Forensics Survival podcast, Michael talks about the strings command/executable and its various uses. One time I found this command particularly useful was for a plist that stored data outside of the regular XML tags, so when viewed with a plist viewer critical information wasn’t shown.

  • Steve Whalen at Sumuri reassures the community that Paladin will remain free/donation supported.
    A Message to SUMURI’s Customers from CEO Steve Whalen

  • Dave/Karit has released his presentation from DefCon 2017 on GPS Spoofing & controlling NTP time. This could have a great application for dealing with iPhones whose batteries have died. For those that don’t know, this resets the time to Unix epoch and occasionally you can turn on an iPhone and it’ll tell you there are x million minutes until you can enter the password – even with the correct password, there’s little that you can do. I really should find an iPhone to test this on and see if when it connects to the network if it automatically fixes the date/time.

  • Patrick Wardle shared his presentation from Blackhat/Defcon 2017 on OSX/FruitFly malware analysis

  • I also released the first “This Month In 4n6” podcast during the week. It’s a quick summary of the happenings of the last month, I don’t know if I’ll expand it further than that, but it’s meant to be for the people that don’t want to read through the thousands of words I write each week. It’s in this feed so I’m not sure why I’m mentioning it again. You can find it on iTunes.
