检测内存中的 Soft-Ice
概述:
有 Soft-ICE
在内存中可不大好玩,以下指令是检测 Soft-ICE
的,不要问为什么,这些都是 Soft-ICE 自己检测自己用的。
汇编编程示例:
code segment
assume cs:code,ds:code
org 100h
start:
mov ax,0911h
;exit command
mov dx,offset d_exit
mov si,4647h
mov di,4a4dh
int 3
xor ax,ax
;check s-ice
mov si,4746h
mov di,4a4dh
int 3
cmp si,4647h
jz found_sice
xor ax,ax
;check s-ice
mov si,4647h
mov di,4a4dh
int 3
cmp si,4647h
jnz found_sice
mov ah,9
mov dx,offset d_ok
int 21h
int 20h
found_sice:
mov ah,9
mov dx,offset d_sice
int 21h
int 20h
d_ok db 'OK,
passed...',0dh,0ah,24h
d_sice db 'I found S-ICE in memory, so
Bye-bye !',0dh,0ah,24h
d_exit db 'exit',0dh,0
code ends
end start
