    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.
      People come in all shapes and sizes, and their ability to grasp rises and falls with professional standing and life stage. It's just how things are.

      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.

      Arrrr!! but sadly us 'normals' are on the decline, normality as checking the road three times before crossing was once a very normal and very sensible thing to do. 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.

      Also, for some reason, most spam (for me) originates from Gmail. I tried setting up a rule to exclude any mail from Gmail, but that backfired. I now create a rule for each jerk who sends their trap-laden tripe my way.

    Excellent video! Bravo for educating internet users how to do these checks.
    On Apple Mac Mail there is a little drop down arrow right of the sender Name, clicking on it reveals the original address, so this is easy to do without hitting reply as suggested in the video.

    As mailserver admin, overall a solid video.
    I do think it's a bit...weird to show the "X% of domains use SPF" statistic when the absolute majority of domains have never and never will send mails. Most people outsource their mails to providers nowadays, because, as you've shown brilliantly in this video, email is a pain.

    Possibly the best attempt at an explanation I've seen trying to bring the subject down to a general computer-user level, although I expect plenty of heads will still explode :-)
    Not perfect mind you, there's some nitpicking to be had in the weeds, but nothing of consequence for your viewers.
    I was impressed that generally when I heard something and went "ahhh, that's a problem/wrong because..." within a minute or two you had covered that case.

    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.

    • @LootFragg

      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.

    A great tip for everyone is when you get a email that claims it's from Paypal or something they will always address you with the name you put in the account not your email address which is Another clear hint it's not from the actual company I noticed that from some Paypal emails when trying to sell something

    • @AlDunbar

      Agreed, salutations like "dear customer" and "dear client" are basically code for "we have no idea who you are"
      That said, I recently received a fake email that addresses me by my actual name. I knew it to be fake as it purportedly came from a company that would have no reason to know either my email address ot my name.
      Lesson learned: don't assume I am. Skeptical enough.

    • @LootFragg
      @LootFragg Před rokem

      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.

  • @fleckzeck5012

    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).

People can just wire thousands of moneys without any safety in place and they do so at the behest of someone mailing them to do so? I am on the wrong side of this.

    One thing I found is Outlook will reveal the URL a control (like a button) is linked to by hovering over the control. Outlook will then print the URL on the status line.

One of the signs is a very slow or overloaded CPU even though you are not running many programs.
