Thank you very much for a very informative post.
Actually as I have noted on a number of the threads, the malware being used is not a script itself, but has script-like effects. A rather large difference.
Ah, so lets sum up what we know so far.
Even though damages from scripts ARE a pain, and even though malicious scripts ARE acknowledged by the security industry and even though Microsoft are making new features available in Windows 10 to fight these problems - then your present malicious code has nothing to do with these.
The name, judging by the comments it produces, seems to be click-bait.
And as it has only been observed in a few recent targeted attacks, it is not a current pain at all.
But if I'm back by the time Windows 10 is released, I'll add one more video to the marathon.
Ah, so what this suggest is that the company you apparently work for has simply discovered a vulnerability.
Nothing new here.
This happens on every OS on a regular basis and has been happening since the very first OS was written.
The usual chain of events for responsible researchers are to report the newly found vulnerability to the vendor of said OS, Microsoft in this case, it will get verified, patched and all users benefit from the added security.
But since you claim you will be back in a couple of months to retest on Windows 10 RTM, we can conclude that it has not been reported in correct channels.
From your posts we can read you work in the IT industry, you and your employer has seemingly not reported found vulnerability and you have chosen instead to use it to make "funny" YouTube videos ??
Could we please have the name of your employer ??
/ sarcasm on
Because I think every CEO and end user in the world, are bursting with excitement to do business with you, when you are gambling with everyones security just so you can harass various companies in the IT security industry on YouTube.
/ Sarcasm off.
