“Microsoft has added support for the /Qspectre flag to Visual C++ which currently enables some narrow compile-time static analysis to identify at-risk code sequences related to CVE-2017-5753 and insert speculation barrier instructions. This flag has been used to rebuild at-risk code in Windows and was released with our January 2018 security updates. It is important to note, however, that the Visual C++ compiler cannot guarantee complete coverage for CVE-2017-5753 which means instances of this vulnerability may still exist.’

Retpoline = “Return Trampoline”

“That’s because when using return operations, any associated speculative execution will 'bounce' endlessly.”

UndertheWire.tech - powershell wargame


PSRemoting -https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/enable-psremoting?view=powershell-6



Caveats:Network connection you’re on must be set to “private”, not public

WinRM service has to be enabled on both the local and remote hosts (at least, I think so --brbr)
