Microsoft Finds 'Raspberry Robin' Worm in Hundreds of Windows Networks (bleepingcomputer.com) 61

"Microsoft says that a recently spotted Windows worm has been found on the networks of hundreds of organizations from various industry sectors," reports BleepingComputer.

The "Raspberry Robin" malware (first spotted in September) spreads through USB devices with a malicious .LNK file Although Microsoft observed the malware connecting to addresses on the Tor network, the threat actors are yet to exploit the access they gained to their victims' networks. This is in spite of the fact that they could easily escalate their attacks given that the malware can bypass User Account Control (UAC) on infected systems using legitimate Windows tools. Microsoft shared this info in a private threat intelligence advisory sent to Microsoft Defender for Endpoint subscribers and seen by BleepingComputer....

Once the USB device is attached and the user clicks the link, the worm spawns a msiexec process using cmd .exe to launch a malicious file stored on the infected drive. It infects new Windows devices, communicates with its command and control servers (C2), and executes malicious payloads...

Microsoft has tagged this campaign as high-risk, given that the attackers could download and deploy additional malware within the victims' networks and escalate their privileges at any time.

  • How is autorun handled in new Windows versions? Older versions had the genius idea of automatically starting an executable that was on a flash drive with no user interaction and this "feature" survived multiple Windows versions. Did they finally kill it in Win11?

      The user has to manually launch the shortcut per TFA (they call it a "link" though, sigh... presumably because it's a .lnk file) in order for the initial infection to occur.

        Yes, I find it interesting that the press shows the user needs to manually do something for this Windows malware to get activated.

        But when they report on Linux malware you get "OMG, Linux is bad", hiding the fact the user not only need to run the object locally but needs to have root access. On Linux you need to jump through loops to get the malware installed. A fact the press loves to ignore.

        • There have been remote holes in Linux distributions (and assorted, bundled software) and there have been privilege escalation holes, and they have been combined to remotely get root. It's presumably more newsworthy when Linux is being exploited because it happens less often, so I take any imbalance in reporting as a compliment.

    Serious question. There's a lot of bitching about bypassing privileges and UAC, because that's frankly easy with five minutes on google if you have hardware level access. Security wise, UAC is very much a lowest possible friction, while being pretty high on user annoyance.

    So does anyone use UAC for security purposes other than limiting potential system damage from ignorant users? If so, why?

      Use full user/admin separation (a seperate admin account, that you never use for user stuff). This is the mode you should use on ANY os (Linux, MacOS, etc) even though they all seem to push you to the one account mode (very bad security). I have been doing this since Windows NT. It solved all the annoying issues of Windows Vista (which is basically Windows 7 with the UAC set to max protection). It will solve the issues with the UAC in the same way (if you are really anal about not running user programs as

        Yes, that is the "do the security right, fuck your usability" way of doing things.

        Thing is, for pretty much everyone in the world, usability is the primary concern, while security is secondary. Notably, this is true for everyone in a field that isn't of their expertise. You probably don't wrap your car's key fob in a faraday cage, and don't harden your windows and doors to extreme degree and purchase specialist locks that are genuinely hard to pick and drill out, because those are not your areas of expertis

    • I've only ever disabled UAC once, back when Vista first came out and an old game wouldn't start properly because of it. I re-enabled UAC later after the upgrade to Win 7, and haven't disabled it since. Many developers tend to be good about abiding by UAC's requirements and have been for sometime. For me, it's a good measure of whether or not an application's developer has done the bare minimum of modern security practices, and whether or not I should use their stuff in the future.

        And then you go home to crappy locks that can be picked in less than a minute, use key fobs for your vehicle that can be extended to open your vehicle without depositing them in a faraday cage when you come home, don't harden your doors and windows against forced ingress and so on.

            It's funny to me that you list a horrific real world setup and then demonstrate the exact kind of apathy for that security that you talk about in that field.

            Which is exactly my point. You don't actually care about security in the field you don't quite understand. You care about usability in everything but the field you understand however. Because your time is actually important to you universally.

            • No I do care. I cannot afford it. My lack of finances and legal ownership does not allow me to avail myself of greater physical security, but that doesn't mean that I lack interest / understanding in it. If you say otherwise, then that's you shoving words in my mouth. Perhaps you should take an interest in what others are telling you. After all security is only as good as it's weakest link.
              • by Luckyo ( 1726890 )

                It doesn't cost much to put your key fob in a small faraday cage. It costs very little to harden your doors to entry as well. If you do it yourself, it's easily less than 100 EUR even at crazy costs of a peripheral nation like mine.

                And yet, you make an appeal to costs in the field that you don't understand, underlying your utter lack of understanding of said field.

                • It doesn't cost much to put your key fob in a small faraday cage

                  Maybe I wasn't clear. I just said, the receiver inside the car doesn't work. In that regard it's better than your Faraday cage because the car will never respond to any fob. Not mine nor anyone else's.

                  I said, I do not own the building. Considering you're quoting Euros, I assume you don't live in the US. FYI: It's illegal where I live to make such modifications to property you don't own. (To a lesser extent, It's also against the terms of my lease.) If I were to do otherwise, I would be hauled in front of

    • So does anyone use UAC for security purposes other than limiting potential system damage from ignorant users? If so, why?

      Because ignorant users aren't the only thing which can execute a payload. Software exploits can as well, and when that payload triggers silently on your UAC disabled account (no different to being stupid enough to run Linux as root) you're owned. On the other hand UAC gives you a fighting chance.

        Almost all "Game As A Service" games nowadays shower you in UAC prompts the moment you start them, due to anti-cheat software. And then there are launchers that are even more fucked up (Looking at you uPlay) and have to ask more than once.

        So if you game a lot, you see that popup... A lot...

        • by Luckyo ( 1726890 )

          Best part is, it will sometimes crash something within UAC. I've seen cases where it needed a hard reboot because the system got locked by UAC prompt, but UAC prompt failed to go in front of the game on the screen and even keyboard shortcuts wouldn't work because it wasn't the element in focus.

        So basically if you don't download porn.exe, you're fine. Which is my original point. UAC offers some protection for incompetent user from himself. It offers little to nothing to a power user.

        P.S. UAC will shower you in those prompts if you play games, or run software that updates frequently.

        It is. It is known that users cannot deal competently deal with such warnings. It has been known for decades. It has been known that the right way to do this is to _not_ offer auto-run and to make users work for it if they want to run something from an external medium.

          And the minute administrators figure out how to turn autorun off, Microsoft changes the mechanism to bypass those settings. Watch them change the policy key you have to use (NOTE - you can use the policy registry tree, most even work on Windows Home).

        I am sure the USB drive is also set to use autorun to run the link. Using USB devices is a security problem anyway. It is more complicated, but use a usb CD/DVD drive to boot rescue utiliies and install an OS (as you can guarantee it is read only). The read-only switch on a usb stick is just a suggestion (like it is on floppy drives). Although a USB drive could be built that enforces the read-only switch (even if the computer wants to ignore it) - personally, this should be the standard.
        • by EvilSS ( 557649 )
          You can't autorun from a USB. They changed that back in Win7 and patched it out in XP and Vista. It will prompt the user if they want to run it (and we are talking users here so...) but it won't automatically run it like it would on a CD in the past. AFAIK there is no way to configure Windows to do it.
