from the will-it-detect-windows-installers? dept.

Arthur T Knackerbracket has found the following story:

Hey, Linux fans! Microsoft has got your back over fileless threats. Assuming you've bought into the whole Azure Security Center thing.

Hot on the heels of a similar release for Windows (if by "hot" you mean "nearly 18 months after") comes a preview aimed at detecting that breed of malware that inserts itself into memory before attempting to hide its tracks.

[...] Microsoft's detection feature scans the memory of all processes for the tell-tale footprint of a fileless toolkit, shrieking a warning in the Azure Security Center along with some details of the nasty. An admin can then decide what action to take (and what further investigation is needed).

The scan, according to the Windows giant, is not invasive and the "vast majority" take less than five seconds to run. More importantly for the those fearful of slurpage, memory analysis is performed on the host itself and the results only contain "security-relevant metadata and details of suspicious payloads".

      I thought that it meant "Expertise in Windows". Where Windows and Malware are interchangeable and equivalent terms.

      Don't get a PC that is infected with Windows.

      Linux is a many splendored thing.
      Linux is all you need.
      Linux lifts us up where we belong.

        Depends on what version of Linux you're using. So far, I'd say the anti-systemd OSes are doing pretty great. While the whole systemd thing seems to be dragging previously top distributions down.

        Unlike file-based attacks, fileless malware does not leverage traditional executable files. Fileless attacks abuse tools built-in to the operating system to carry out attacks. Essentially, Windows is turned against itself.

        So, let me get this strait, a Windows solution, for linux, to Windows turning against itself?
        -

        I think it behooves every linux admin to refuse to run any software that protects Windows from itself, or any virus or malware scanners for Microsoft virii or malwares, and to serve as much of these "nasties" as feasible, to help end Windows as soon as possible. From orbit. It's the only way to be sure.

          While I don't disagree with your sentiment, I feel I should point out that the article is Windows-centric, which is why it is phrased as it is.

          I don't see how fileless malware designed for Windows would work on linux well enough to propagate. But I don't have difficulty believing that there is linux equivalents to this class of malware, so I can see value in this kind of software.

            Well, most Windows-based malware these days seems to be "ransomware", where they lock up your files and get you to send them BTC to decrypt them.

            So, more accurately, one is something you pay for up-front, the other is free at first, but charges you later.

      A great business model is to sell the cure for the problem you created. Exclude, or at least be a gatekeeper for competing anti-malware products.

      Also, have you heard of: Microsoft Defender ATP for Linux? [microsoft.com]

      CAUTION: Running other third-party endpoint protection products alongside Microsoft Defender ATP for Linux is likely to cause performance problems and unpredictable system errors.

      Prerequisites

              Access to the Microsoft Defender Security Center portal
              Beginner-level experience in Linux and BASH scripting
              Administrative privileges on the device (in case of manual deployment)

      I think their marketing should have named it: Microsoft Maginot Line Defender

      You don't need to do that. If your sheep are sick, they aren't going to get your chickens sick, because pretty much no virus can cross species (genuses? families?) like that. It's the same with Windows and Linux; you don't have to worry about any Windows crap infecting Linux. (However, it is possible that Microsoft the company could engineer something specifically to target Linux... but you segregating Windows from it won't affect this.)

    If my linux server had a virus...

    I would expect the virus to use less resources than any bloated microsoft program.

    I also would expect less information would be stolen by hackers than microsoft's "telemetry."

    And to top it all off, I can get a virus for free.... not pay on ongoing license fee to microsoft.

    Unit 8200 Offers New Malware Removal Tool for Linux!

    Headline from the future: New Bug discovered in Linux was used since 2020

    Does this mean there is an actual threat here, like you might get an attachment that could infect you even if no file is downloaded?

    And without Azur-, Unit 8200, we have no defenses?
