这一行较为可疑 因为Windows默认没有这个东西,说明这就是病毒的模块,地址为0x7fefad10000

下一步去提取密码 python vol.py -f quzheng.vmem windows.hashdump

题干:

寄,突然发现电脑似乎被控制了!

请回答以下问题,答案使用 CBCTF{} 包裹,所有答案均在本题提交框输入

(1)flag.txt

(2)我的用户密码是什么

(3)攻击者尝试使用python弹计算器恶搞我,但是失败了,找找命令中的flag吧

(4)木马文件名

(5)反连地址,例:CBCTF{127.0.0.1:80}

1)直接爆搜flag即可获取结果
2 )python vol.py -f quzheng.vmem windows.hashdump
然后hashcat爆破

3)我们获取到几个碎片:

python -c "eval(bytes.fromhex(‘657865632822613d5f5f6275696c74696
exec("a=builtins.__

s.fromhex(‘657865632822613d5f5f6275696c74696e735f5f2e5f5f646963745f5f5b276279746573275d285b3
exec("a=builtins.dict[‘bytes’]([

初步猜测 这是在试图使用16进制转换的方式绕过明文调用,但是获取到的都不完整。
于是逆向思维查找 ,既然要调用calc 那么一定会存在:
Forensic

所以逆向查找,真的找到了恶意构造的payload:
Forensic

于是提取到了完整的payload:

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'))"

flag_in_cmdline_very_easy]);print=__builtins__.__dict__['eval'];print(__builtins__.__dict__['bytes']([95,95,105,109,112,111,114,116,95,95,40,39,111,115,39,41,46,115,121,115,116,101,109,40,39,99,97,108,99,39,41])))

得到flag

4)5)直接找网络相关调用 发现了有一个奇怪的应用正在建立tcp链接,并且根据之前3)得到的线索,可以发现这个192.168.88.1就是恶意地址。所以得到:

恶意软件 fbf56526tcp.exe  
反链地址 192.168.88.1:8084

CBCTF{has_lots_of_ways_to_get_this_flag}
