panic: strings: negative Repeat count

[jamesjguthrie]

Hey,

When trying a number of the example commands including:

Ivy -stageless -Ix64 stageless64.bin -Ix86 stageless32.bin -P Inject -process64 C:\\windows\\system32\\notepad.exe -process32 C:\\windows\\SysWOW64\\notepad.exe -O stageless.js

I get the error:

panic: strings: negative Repeat count

goroutine 1 [running]:
strings.Repeat(0x569f21, 0x4, 0xffffffffffffffff, 0xc00007ed78, 0x40971b)
	/usr/lib/go-1.13/src/strings/strings.go:533 +0x5aa

I'm running v1.12 on Ubuntu 20.04.3 LTS with the dependencies installed per your instructions.

Oh I just noticed that stageless32/64 binaries don't exist. Is your intention that we use a tool like Meterpreter to create those payloads?

stageless is a universal thing, most frameworks can and do stateless. That being you need to do raw shellcode not compiled binaries as the input.

Is this still an issue?
