This module is a port of the Equation Group ETERNALBLUE exploit, part of the FuzzBunch toolkit released by Shadow Brokers. There is a buffer overflow memmove operation in Srv!SrvOs2FeaToNt. The size is calculated in Srv!SrvOs2FeaListSizeToNt, with mathematical error where a DWORD is subtracted into a WORD. The kernel pool is groomed so that overflow is well laid-out to overwrite an SMBv1 buffer. Actual RIP hijack is later completed in

Uses information disclosure to determine if MS17-010 has been patched or not. Specifically, it connects to the IPC$ tree and attempts a transaction on FID 0. If the status returned is "STATUS_INSUFF_SERVER_RESOURCES", the machine does not have the MS17-010 patch. If the machine is missing the MS17-010 patch, the module will check for an existing DoublePulsar (ring 0 shellcode/malware) infection. This module does not require valid SMB
