一个DumpDex的IDA插件

源码

import idaapi
import struct


def dumpdex(start, len, target):
 rawdex = idaapi.dbg_read_memory(start, len)
 fd = open(target, ‘wb‘)
 fd.write(rawdex)
 fd.close()

def getdexlen(start):
 pos = start + 0x20
 mem = idaapi.dbg_read_memory(pos, 4)
 len = struct.unpack(‘<I‘, mem)[0]
 print ‘len is ‘ + str(hex(len))
 return int(len)


start = AskAddr(0, ‘Input DexFile start in hex: ‘)
print(‘start is ‘ + str(hex(start)))


len = AskLong(getdexlen(start), ‘Input DexFile len in hex: ‘)
target = AskStr(‘/users/boyliang/temp/xx.dex‘, ‘Input the dump file path‘)


if len > 0 and start > 0x0 and target and AskYN(1, ‘start is 0x%0x, len is %d, dump to %s‘ % (start, len, target)) == 1:
 dumpdex(start, len, target)
 print(‘Dump Finish‘)

用法

• 首先shift + f2，调出IDA，选择import，把本脚本导入
• 当动态调试的时候，找到dex的始址，比如断点在dvmDexFileOpenPartial，r0即是dex的始址
• shift + f2，调出脚本，选择本脚本，按UI提示输入即可

注意: 这个小插件目前只支持连续的Dex文件，非连续性的不支持
