Chapter 3 – Dynamic Analysis – Techniques and Tooling

The challenges in Chapter 3 focus on automation and dynamic analysis of samples. The answers are as follows:

1. This malware sample does not appear to create a persistence mechanism immediately following execution.
2. The file will write one decoded payload to C:\Users\Public\*.GOF with the SHA256 of 47b1f63e7db1c24ad6f692cf1eb0e92dd6de27a16051f390 f5b441afc5049fea.
3. Checking for alternate data streams via PowerShell reveals no hidden data within our payload.
4. If there were persistence mechanisms or files uncovered by our script(s), we could easily add a pipeline element to Remove-Item or similar in order to automate the removal of files and registry keys. The same could be used with scheduled tasks via Unregister-ScheduledTask.
