I'm trying to develop an alphanumeric payload that needs to do a JMP -600 bytes...
Anyone got any ideas how to do this with only alpha numeric chars?
'eb' and 'e9' are obviously out of the question...
Think "encoding/decoding" and "self-modifying".Anyone got any ideas how to do this with only alpha numeric chars?

EICAR.COM has been doing it for more than decade to get its INT (cd) op-
codes executed, so this is hardly revolutionary new territory...
Beyond that, I'd be extremely surprised if someone hasn't written
tutorials on doing alphanumeric-only payloads, if not even provided
toolkits to take arbitrary code and "ASCII-fy" it.
