Radar2中的ASM模式搜索

问题描述

我想在radare2中搜索该类型的ASM模式

pop,mov,mov

这是三个连续的指令：第一个以 pop 开头，第二个以 mov 开头，第三个也是。

存在一本有关Radare2（https://github.com/radareorg/radare2/issues/13322）的相关问题，并说“在/ c中实现了它的通俗易懂”，但是搜索加密材料现在需要/c。 / p>

我正在Linux上使用radare2 4.5.0。

解决方法

这可以通过 /ad 实现（使用 4.5.0 和 5.0.1 版测试）：

r2 /bin/ls
> "/ad pop;mov;mov"
0x00009b40   # 7: pop rbp; mov rsi,r13; mov rdi,r12
0x00009bb8   # 7: pop rbp; mov rsi,r12
0x00009c38   # 7: pop rbp; mov rsi,r12
0x00009d40   # 7: pop rbp; mov rsi,r12
0x0000a120   # 19: pop r12; mov byte [rip + 0x1832c],0; mov dword [rip + 0x1817e],0
0x0000a120   # 18: pop rsp; mov byte [rip + 0x1832c],0
0x000120f1   # 9: pop rcx; mov rcx,qword [rbx]; mov edx,2

注意：命令周围的引号 (") 是必需的，因为radare2 还使用分号来链接命令。

供参考（radare2 5.0.1）：

> /a?
Usage: /a[?] [arg]  Search for assembly instructions matching given properties
| /a push rbp           Assemble given instruction and search the bytes
| /a1 [number]          Find valid assembly generated by changing only the nth byte
| /aI                   Search for infinite loop instructions (jmp $$)
| /aa mov eax           Linearly find aproximated assembly (case insensitive strstr)
| /ac mov eax           Same as /aa,but case-sensitive
| /ad[/*j] push;mov     Match ins1 followed by ins2 in linear disasm
| /ad/ ins1;ins2        Search for regex instruction 'ins1' followed by regex 'ins2'
| /ad/a instr           Search for every byte instruction that matches regexp 'instr'
| /ae esil              Search for esil expressions matching substring
| /af[l] family         Search for instruction of specific family (afl=list
| /ai[j] 0x300 [0x500]  Find all the instructions using that immediate (in range)
| /al                   Same as aoml,list all opcodes
| /am opcode            Search for specific instructions of specific mnemonic
| /ao instr             Search for instruction 'instr' (in all offsets)
