back to article Don't open that WhatsApp message, Microsoft warns

Be careful what you click on. Miscreants are abusing WhatsApp messages in a multi-stage attack that delivers malicious Microsoft Installer (MSI) packages, allowing criminals to control victims' machines and access all of their data. The campaign began in late February, we're told, and the attack chain starts with a WhatsApp …

    Employee training tops the list ????

    No, actually, it doesn't. Installing a sane email system, one which doesn't provide the flaw of directly running programs arriving by email, has got to take priority.

    Failing that, setting options to prevent the running of such programs has got to be possible.

    Saying "training tops the list" is unjustly to transfer the blame for the situation from Microsoft to the users.

      What "flaw of directly running programs arriving by email" are you on about? There isn't one. The sender has to trick the user into running them manually.

      And options to prevent people executing them manually? Yes, the IT department can do that and have been able to for years. Not Microsoft, the local admins who have the control over what users are allowed to do. Either they haven't because users sometimes need to execute unknown things, in which case you have to train users, or they haven't but have no reason not to, in which case you have to train IT employees.

        Normal email systems, such as most users use, just block VBS out-of-hand.

        As a programmer, I found it annoying that most email systems would block even something as harmless as raw c code - not executable in any sane common user environment - but I've got to wonder if WhatsApp is sanitized at all?

          I fondly remember being able, decades ago, to be able to run some extremely amusing Display Postscript on NeXT beasties, that did things like melt the users screen (visually) when they opened emails. Highly amusing to my tiny mind at the time. That got fixed, bu MS as you say did have a wee problem for a while

      I’m sorry, but this is a nonsense.

      Employee training is absolutely the single best strategy to assist in preventing malware and social engineering attacks.

      Where I work it’s taken incredibly seriously.

      Everyone gets training and there’s periodic fake scam email tests. We have an extra button in our email software to report dodgy emails.

      The detection rate by staff has increased from around 55% to nearly 90% in 2 years.

      We’ve also all had to go through multiple sets of security training depending on role and some of these have been intense and very educational.

    Surely an advanced professional operating system wouldn't allow a user to overwrite system files without providing the system manager's credentials ?

        ..or click [Yes] if you're running as a user with Administrator privileges. That's common in home environments but I'd hope far less common in the business world where a decent IT department is available.

    I wasn't even aware Whatsapp existed for Windows PCs. I just assumed it was a mobile app and they have a web version.

    1. doublelayer Silver badge

      It won't work unless you've first set up one of the mobile versions, but you can use it from the desktop clients as well. It's surprisingly common for business communication internationally, and I'm guessing that's why the desktop version is used so much.

      1. I ain't Spartacus Gold badge

        We're starting to use Whatsapp quite a bit at work. I think it's because people on site aren't always being given a company mobile, so if you email them they don't get it until they can get to their laptop - which might be in the site office or even at home. But with Whatsapp they can send you a photo of the broken kit from wherever it is, and they can read the datasheet or manuals you send them back. it's not quite gone far enough that I've installed it on my PC - but I can see that happening, if I end up using it as much as one of my colleagues.

        We're even looking at the possibility of connecting Whatsapp to our CRM system - so we can send people copies of quotes.

    2. AndrueC Silver badge

      You have to attach it to an existing mobile account and it's clearly subservient to that. Also since last year it has been updatedchanged to use the Electron framework and has a number of rough edges. The user experience can be quite clunky now.

          that's the US Enshitification of this site. Downvote any post that uses this sort of term.

        2. Sub 20 Pilot

          Anyone who sends me any message with ''reach out'' or other such nonsense in it gets the message binned.

          I look after a small catch all email account for our volunteer first response team and I get a load from companies trying to sell us stuff, which is parasitic enough but when they are full of buzzword bullshite it automatically puts those twats off my purchasing list.

          In my professional role I have to deal with a lot of contracts managers who love the wanker-speak so I put them right at the start. I inform them pretty bluntly in the next site meeting that if they want me to read their emails they write in Welsh or English, hell even French if they want but no text speak, no wanky marketing buzzwords. I have done this for years, responding to mangled messages with trendy (at the time) txt abbreviations in a professional email with a blunt return email asking them to send it in a recognised language if they needed a response. I am pretty fortunate that I can do this as these people need my input.

          If more people did this it would remove most of the abomination of marketing speak. Worst people by far are those that have a huge linkedin presence and loudly state so in their email sig. Tossers.

      If it was written by a human, the term is grandiloquent.

      But it was never even looked at by a human before release. It is pure AI. The goal of this kind of missive is to make the merely plausible sound like the best thing since sliced bread. Unfortunately for the idiots using it, what it really does is make said idiot sound like a complete wanker (as noted by the OP), even though they never even bothered to read it, much less write it.

      I hear this so much every day. Levverage this. Levverage that. I don't massively mind Americans doing this but when I hear supposedly intelligent Brits doing it, it makes my skin crawl. We don't have levvers here. We call them levers. And the verb is to lever.

      Americans can pronounce it how they wish; nothing wrong with that. But leverage is still a noun.

      Getting this wrong just makes you look like a sheep who didn't pay attention at school.

      As for "on-premise", don't get me started.

      Re: WhatsApp?

      I don't trust Meta not to use WhatsApp to illegally acquire data on any device it's installed on. They have already been caught doing it at least once (when they transferred contact lists from WhatsApp to Facebook). In the EU, all we have is their pinky promise that they won't do it again, and outside EU there's not even that.

      I don't trust them, a business certainly shouldn't trust them, and providing a service, internal or external, only through a system that requires ceding personal data to a third party, ought to be straight up illegal.
