When honey is very cold, it drips in a supremely elegant slow way off the spoon down to the waiting latte: the ants may have time to crawl all the way up you, and out on your suspended arm holding the spoon, and, if they fall while tasting that cold honey, fall into the latte, who is to say if that ant's life was fulfilled, or wasted ?

But stuff that is in the middle category you don’t want to restrict unless there is a clear way to work around it.» Eric Lippert, May 14, 2008

Well, when you consider that we're moving towards AI doing IP, I guess the line gets rather fuzzy.

I and family members have seen a nasty increase in malware emails that most likely will plant a Ransom Virus if the attachment is acted upon. We now get several every week and sometimes several in one day.
One of the most insidious is an email where the sender is spoofed to be Amazon. The "Amazon" message will seem to announce a shipment having been sent. However, there are two tell tale warning signs: 1) It is sent to an email address that only my friends and family know. I use a different email address for Amazon. 2) The message is empty, except for an attached Word document. Amazon never attaches Word documents to their emails. Like I'm going to open such a Word document and run the risk of a malicious macro getting run on my machine. 
The other type will be an empty email from myself to myself. It has an attached zip file that contains a Javascript file. If you look into the message header it is full of Arabic characters and is sent from a domain in Iran. Of course I am in the habit of running Javascripts from unknown sources on my machine.
Now here's the bummer: If I scan these obviously malicious messages with Defender and Malwarebytes, they come up clean! I was wondering if anyone else has had similar experiences?

Next time I get one, I will see if I can get it to you. (I don't think CP will appreciate it, if I sent it to you via their servers.)

I could send you a few - well, could if I wasn't anon. Oh well.
Let me tell you, from what I've dissected from every single one of them, is they go thru about 1 or 2 levels of obfuscation of the code (eval'ing one segment to run another segment that eval's a third), plus a bunch of weird function calls (like calling one function to get a bit of a string, calling another that evals it and returns the result, calling a third to get another piece and multiply it by 5, then calling yet another to take all those pieces as arguments and return a concatenated string of substrings - that kind of stuff), ultimately what resolves/results is a URL that is then queried using an XMLHttpRequest object (aka, AJAX), or something similar - that goes out to some server (ident'd by IP or some domain), grabs an EXE, saves it, and executes it.
It's obvious from all the layers of obfuscation that the code is made this way - likely by some kind of "trojan generator" (which can probably be easily found on the dark web or elsewhere) - to both get by filters for trojans, as well as make it difficult for most people to decipher what is going on if they see the code. Ultimately, none of this is very interesting or unique - it's all a well known form of attack and documented.
Generally, though, that IP/domain has already been disabled, or the EXE has been deleted or wiped, at least in most of the cases I have tried. Only on a very few occasions have I been able to download the executable. In those cases, I try to alert the owner of the IP or domain if I can do a whois or reverse DNS search to know what provider I am dealing with - then I'll send an email to the admin contact or wherever.
I find it funny, though, when I get these emails - I always try to figure them out, hoping someday that what I'll download is a bash script or something similar; you see, my main workstation has been a linux box of one form or another since 1995 or so - and I keep hoping that these guys move on to doing things targeting Macs, Linux, or some other *nix platform, but it hasn't happened yet.
Even if it did run, the worst thing that will happen is that I have to re-image from a backup of my system - big whoop. The upside will be that I will know for certain that the "year of linux on the desktop" has finally arrived, and that linux has "jumped the shark", and I need to move to another obscure platform (maybe BSD? lolz) just to stay ahead of the game.
I'm not holding my breath on that, though - and for that, I am thankful!

For the last month I've also seen a massive increase in these emails and I now also get several a day. Most are easily seen as fakes but some are actually scarily good. Not good enough to convince me to open the attachment, but I'm sure many will be. Some emails appear to be copies of actual invoice emails sent from the alleged source company so everything checks out, the contact numbers, the "from address" and it looks legit. I also feel sorry for the companies that are being spoofed as I saw the rise of these emails on the BBC and they say that the companies being spoofed are being inundated with calls from angry people asking why they are chasing invoices for things they didn't order.

Oh yes, I forgot about the fake invoices. I get those too.

And the fake tax refunds, had one that looked very much like an HMRC mail, but they don't send attachments.
|

HMRC definitely don't send attachments with refunds, that's for sure.
I may not last forever but the mess I leave behind certainly will.

Usually I don't - I mean, U receive a lot of those e-mail but they are egregiusly filtered by Big G spam filter and end up in the Spam folder. I rarely receive spam or phishing between the good e-mails.

Just under 5% of the emails I get are junk: adverts, spam, phishing, and such like - nearly all of which I never see because it goes straight to my "junk mail" folder via the Live Mail rules I have set up. Every now and then I go through and forward phishing mails to the supposed originator.
But so far I've not seen anything like you describe.
I still do regular-and-often backups though!

Probably!
I find that if you have a backup, you probably won't need it. If you don't...

Yup! And having full backups takes fear out of the equation, doesn't it? Knowing you can recover from an attack gives you peace of mind, even if it never happens.

Some of the latest viruses put out by the NSA implant themselves into the firmware of hard drives or bios, so that the machine is ruined. You cannot do a restore and expect to be rid of the virus.

I only get these via one of my email accounts - the one with a bcs.org address. I would have hoped that the BCS (British Computer Society) would have been sufficiently computer savvy to host their emails on a server with decent spam filters.

Don't worry. Letting windows update own your computer and rule your life will solve all your problems.
Oh, wait...
No it won't. It'll just "fix" things that work.
The best process security and peace of mind is, and has always been, "don't do anything stupid".
If you use Outlook (the MS Office version), one trick is to drop suspect files into the "Junk E-mail" folder before opening them. That disables anything that could do a nasty.
But I prefer the "If in doubt, delete" method. Failing to open a genuine e-mail will not add or remove a second to or from your lifespan.

Precisely! Same here. But maintaining good backups does not hurt. Ransom viruses are also spread by hacked "good" websites. There is always the risk of visiting a supposedly safe website that has been hacked.

This is the exact reason why I typically use Firefox with NoScript and AdBlockPlus (extended with my own personal filters). It has made the internet a pretty spartan place and there are some websites that don't even load anymore but I consider any website that will not fulfill its basic purpose without scripts or linking to 12 other sites as poor web design and not worth my time (and by basic purpose, I mean displaying information). If I need the full capabilities of a website, I turn on what is needed or switch over to Chrome. The end result is that I have ultimate control of what web content is allowed to run on my PC.

This is so unnecessary! See this thread:

I am in total agreement with that. All that unnecessary junk steals my bandwidth even if my browser settings block it from being rendered. If I may also play devils advocate, I also understand that many websites depend on advertisements to supply their operating capital BUT the broad spectrum tactics that most ad services utilize, showing you a million ads in hope that you click one, is reliant on quantity and not quality. In my opinion, one or two high-quality, content-targeted ads per page is more than enough. Three dozen ads trying to sell me the latest pharmaceutical product or another product that I have no need for is a waste of money on both ends and does the advertising industry a disservice.
