Systems, Network, and Administration Podcast. Every two weeks TechSNAP covers the stories that impact those of us in the tech industry, and all of us that follow it. Every episode we dedicate a portion of the show to answer audience questions, discuss best practices, and solving your problems.
Episode 348: Server Neglect
Authors of one of the most infamous botnets of all time get busted, researchers discover keyloggers built into HP Laptops, the major HomeKit flaw no one is talking about, and the new version of FreeNAS packs a lot of features for a point release.
Plus an update on the show and what to expect, and we attempt something TechSNAP could never do as a video production, a live double FreeNAS upgrade!
Mirai IoT Botnet Co-Authors Plead Guilty — Krebs on Security — The U.S. Justice Department on Tuesday unsealed the guilty pleas of two men first identified in January 2017 by KrebsOnSecurity as the likely co-authors of Mirai, a malware strain that remotely enslaves so-called “Internet of Things” devices such as security cameras, routers, and digital video recorders for use in large scale attacks designed to knock Web sites and entire networks offline (including multiple major attacks against this site).
HP keylogger - ZwClose Blog Post — TL;DR: HP had a keylogger in the keyboard driver. The keylogger saved scan codes to a WPP trace. The logging was disabled by default but could be enabled by setting a registry value (UAC required)

Process Doppelgänging Attack — Dubbed ‘Process Doppelgänging‘ by Tal Liberman and Eugene Kogan of EnSilo, the attack was demonstrated during Black Hat Europe 2017 security conference in London earlier today. Doppelgänging, a fileless code injection technique, works in such a manner that an attacker can manipulate the way Windows handles its file transaction process and pass malicious files even if the code is known to be malicious.
Process Doppelgänging - Black Hat Europe 2017 — By using NTFS transactions, we make changes to an executable file that will never actually be committed to disk. We will then use undocumented implementation details of the process loading mechanism to load our modified executable, but not before rolling back the changes we made to the executable. The result of this procedure is creating a process from the modified executable, while deployed security mechanisms in the dark.
