comment Null Session Questions
@raven A CS student might well think it's a good question, but that doesn't make the question fit for StackExchange. I'm still not really understanding what you're asking - but I'd take a guess that you want to know whether a locally created named pipe can be accessed remotely via SMB, using the Anonymous logon (null session). Did I get that right?

comment How can I confirm I'm vulnerable to OS X “rootpipe” (CVE-2015-1130)?
Also, check if your filesystem is mounted nosuid.

Did you run id -u to show the effective UID?

comment Email phishing scam asking customers for card details
"Contact gmail" - care to point to where? I'm not sure that they have a generic abuse contact point.

comment Email phishing scam asking customers for card details
First thing: Send out a mass email to your customers explaining that this is happening, warning them NOT to reply to any requests for personal details or financial information via email, and assuring them that you will NEVER ask for such information.

@raven You should keep in mind that StackExchange has very specific question quality requirements, to avoid large numbers of poor questions and answers which drown out the quality content. Don't take it personally.

comment Null Session Questions
@raven I've read your question a number of times, and am familiar with Windows networking and SMB, but still don't understand what you're asking. You've mentioned null sessions a bunch of times, and asked if Windows still "uses them" (which in itself is vague - does it use them for what?), but you haven't been clear about what specific security question you have. Feel free to edit your question (there's an edit button underneath it) to clarify exactly what you're asking.

comment Is VBScript an actual tool to attack users?
I'm too drunk to check right now, but if I remember correctly Chrome, Firefox, and Opera can run VBscript if you enable it.

A lot of browsers also don't run VBScript by default.

comment How does consent.exe know what to display?
Good question. Could you check if the second number is a valid thread ID within the process?

comment Achieving PFS with public key cryptography
It was just a number I pulled from the air that wouldn't cause any tangible harm to security should it be taken literally. Feel free to replace it to fit your security bound.

comment can you know the computer that an email came from?
Are you talking about the sender's IP? Because that is often recorded in the headers, though obviously the sender may use an anonymous mail agent or other anonymising methods (e.g. a proxy, VPN, Tor, etc.) to send the mail.

comment How to convince my management of a physical security risk?
@RoryAlsop FC's talks are never recorded, unfortunately. Makes sense, as he wants to minimise the number of people who know what he looks like.
