Abstract
Attackers are starting to move on from simple attacks, mainly because users are starting to figure out that the free adult entertainment or chat app shouldn’t be sending SMS messages to expensive numbers. They’re leveraging techniques from PC malware like server-side polymorphism, vulnerability exploits, botnets and network updates, and preemptive/direct attacks against security software.
It’s not all that bad. Attackers aren’t going out of their way to discover their own vulnerabilities or writing their own exploits. They’re happy to repurpose the work done by legitimate developers, security researchers and the rooting community.
If the malware has gotten trickier, what are those tricks? We’ll look at portions of code (bytecode/decompiled Java source & disassemblies) from in the wild mobile malware and show how earlier research is adapted by attackers.

Here is a summarized version of the content:
The speaker is discussing the benefits of using PowerShell, CScripts. They mention PSC X, which is a collection of scripts that can be used to manage Office 365 and NTFS security. The speaker also highlights the usefulness of the start and stop transcript commands in PowerShell, which allow users to record their commands and output for later reference.
The speaker then explains some fundamental concepts in PowerShell, such as:
- Everything is an object, which can be manipulated using pipelines.
- Variables are prefixed with a dollar sign ($) and can be named anything except for special variables like
_and$true. - The pipeline concept allows users to chain multiple commands together.
The speaker then moves on to discuss file permissions in PowerShell, stating that they can be painful to work with. They demonstrate how to use the Get-Acl and Set-Acl cmdlets to manage permissions, but note that these commands can be cumbersome to use. The speaker suggests scripting these tasks to make them easier to perform.
Finally, the speaker mentions a PowerShell module created by Raymond Andre from Microsoft that simplifies working with file permissions. They demonstrate how to use this module to set permissions on a folder.
