    Wanna know what you do? Get a font that only has the a-z characters, and also a couple other important ones like 0-9 and some important symbols. Then set a fallback font to make the email address super obviously not latin characters. This is how you COULD do it.

      sorry but I'm the speaker of a language that doesn't use a Latin script so that obviously wouldn't work for me
      so what do I do
      I copy the text, split it into characters using Node.JS and convert them into Unicode codes
      if any of the symbols is greater than 255 then that's obviously not an ASCII character

    • @DeactivatedCharcoal
      @DeactivatedCharcoal 3 роки тому +19

      I use a programing font for normal viewing that makes all characters VERY clearly distinctly different. so Capital O and the number ZERO and Lower Case L and the number ONE can never be confused. When I get a weird email I switch to a special "hand writing / cursive font" that looks really nice (but the author of the font did not do every single font just the standard ASCII. Any non-ASCII jumps out like a sore thumb.

    I've been tracking spammers since the 1990s, and this video definitely covered the bases without getting too hairy for most folk. This can be an intimidating task, so simple straightforward examples are key and should cover most such threats.
    Good coverage of caveats, too. There are so so many angles, and limitations, so those this-but caveats are important. Something can look clean, but still fail the sniff test (BS Meter).
    Great job!

      @@mikeowens6291 no, most email users do not get it. I work with reasonably technical people who have difficulty with some of the concepts. The engineers and senior sysadmins understand, of course, but lots of others can only grasp most of it.
      The lay people, on the other hand, don't even understand the idea of other typesets. They understand that Kanji is clearly different, but visually nearly identical characters mixed with English is a step too far to grasp. Many of these are older folk, often retired, all with degrees of various levels, one even a retired programmer for Wells Fargo.

So often I now see mainly young people with their nose in their mobile who just walk into a road with traffic and then screen and shot at a driver who has had to slam on their breaks and the pedestrians truly believes the driver is in the wrong. The same goes for people reading their emails who now instinctively as they do walking and looking at their mobiles click onto hypertext. Sadly, the day of 'normals, will soon be no more.e

      The idea is to run these checks when you come across something fishy, not for every email you receive.
      Problem is that what's shown here is pretty much all specific to gmail. (Thunderbird is my client software, and it's not even mentioned.) I check the full header when in doubt; it's mostly gibberish but the domains do stick out, and in my experience you'll find the usual suspects (.in .ru .cn .bg etc.) if it's spam or a scam.

      I usually notice the scam content long before I notice the sender is off. I always check for what it is the mail wants me to do and that just removes 99% of mails from the list immediately.
      Also, my mail client shows me the link text if I hover over hyperlinks, so that's a huge thing. If anything points anywhere in a country I don't know, it most certainly is a scam.

One thing BTW, at minute 26 you explain the hash verification, and I am pretty sure is: sender signs hash with sender private key, and receiver verifies with sender public key. That is usually how software binaries are verified by people who download them from open source sites. You can only verify or encrypt with the public key.

    Oh boy. Thumbs up BUT despite your hard work and detailed explanations it's all beyond my understanding. I did learn a few things though, some of them that I actually have the capacity to absorb. I know that people who really know their subject want to pass the information to their audience which results in going into overtime. It's what happens when you know your stuff. It's obvious that you know it. I have screwed up my computer in so many ways and so often (I'm in the middle of screwing up my outlook) that I don't even know how to reverse it or how to fix it, or how I got there in the first place. Although, from videos like yours I've learned to do a couple of things with questionable email. I don't open anything and I block the sender. Mine is just for home use though, and I can imagine that business computers and their email have to be scrutinized. See, I went further than I intended to as well.

      I think the most important thing you can do is be skeptical. Ask twice. If you don't know how to verify something, get someone tech savvy to do it for you.
      It's what I do when people write really scammy-looking mails but it isn't clear whether they're real: I just ring them on the channels I know, asking if the thing is from them. Mails are never urgent. If someone writes a scammy-looking mail, they will have to live with you not responding to it.

    Speaking of similar looking unicode characters. It would be cool if they color coded or used bold/italics for any character outside the ascii range.
    For example: Standard ascii characters would just be black like it usually is and other character would have a color, like red for example.
    Also, it would give you a warning to let you know what it means like "NOTICE: Colored/bolded character(s) detected. Phishers may use this to their advantage.". It would help alot since I have bad vision and the examples you've shown look pretty much the same (The fake 'a' and real one).

    SPF and DKIM do authentication only, they don't provide any enforcement.
    That is what DMARC is for.
    Also, FYI, by default, O365 Enterprise tenants are configured to softfail regardless of what a domain's DMARC record is configured for. You have to enable full DMARC compliance if you want it configured that way.
    From the domain owners perspective, DMARC also provides a statistical and forensic mechanism so you can not only prevent unauthorized senders from using your domain, you can collect statistical information from email relays on the internet that lets you know how many emails "sent" from your domain are legitimate vs spoofed and which email servers are trying to spoof your domain. These statistics enable you to calculate a DMARC compliance rate which can tell you if someone is attempting to use your domain maliciously.

    One of the best defences against such scams is to have several email addresses - one that only your friends and family have, another for your bank, a third for well known suppliers and trusted companies and several throw away ones that you only give out to folk that you don't really trust. (You can make this easy by using forwarding on them, so that you don't have to log on to several servers.) Then when you get an email from "your bank" about an apparent problem with your account (already highly unlikely) and it arrives on one of your throw away addresses, you know immediately that it's fake because you don't use that email address for banking,
