⛓ Divide and Rule — AMSI Bypass

By spliiting well known PowerShell scripts, e.g. an AMSI Bypass, we can directly bypass Windows Defender or get at least the line, where the detection occurs. Outcome: Several AMSI Bypasses and two scripts:

- One to split PowerShell snippets in multiple lines
- A second script to run all the files in an Oneliner, XOR obfuscated
