arma_detach.txt

700个脱壳脚本, 可以放在在OD的ollyscript Plugin中.

/*
Armadillo script - detach parent from client - by hipu
tnx to Ricardo for his complete instructions (im just emulating what the man says...)

MAKE SURE ALL BREAKPOINTS ARE DELETED BEFORE EXECUTING THE SCRIPT!!! 

ALSO: since im using the IsDebuggerPresent plugin, i didnt do IsDebuggerPresent patch.
do whatever is needed if u dont use the plugin...
