Cops Hijack Botnet, Remotely Wipe Malware From 850,000 Computers (vice.com) 79

French police, with help from an antivirus firm, took control of a server that was used by cybercriminals to spread a worm programmed to mine cryptocurrency from more than 850,000 computers. Once in control of the server, the police remotely removed the malware from those computers. Motherboard reports: Antivirus firm Avast, which helped France's National Gendarmerie cybercrime center, announced the operation on Wednesday. Avast said that they found that the command and control server, which was located in France, had a design flaw in its protocol that made it possible to remove the malware without "making the victims execute any extra code," as the company explained in its lengthy report.

Cybersecurity firms such as Avast, as well as Trend Micro, had been tracking the worm, called Retadup, since last spring. Most of the infected computers were used by the malware authors to mine the cryptocurrency Monero, but in some cases it was also used to push ransomware and password-stealing malware, according to Avast. As the antivirus firm reported, most Retadup victims were in South America, with Peru, Venezuela, Bolivia and Mexico at the top of the list.

      this, and given the fact that the only 100% reliable way to 'disinfect' any compromised device is resetting it to factory settings, i wonder what such a 'remote removal' procedure would accomplish. this malware must have been utterly trivial to even consider this as something worth trying. i hope they at least sent notifications to all affected too. this all sounds really weird.

          Even executing a single command on a computer without permission is a crime in many jurisdictions. It really does not matter what they did for that. Of course, they could have committed multiple additional crimes along the lines of your description.

              are you aware that it's pretty trivial to have hardened os images ready that can be restored in a blink, and that backups exist?

              once a system is compromised you can't really trust it anymore except in the most trivial cases. it is pretty hard to figure out how deep the intrusion has gone. every sane security expert or sysadmin will prescribe a prompt reinstall (probably after quarantine and research). home users can be fine with their flashy antivirus swearing in nice colored fonts that the threat has been

          • Factory reset computers are sorely lacking in the months or years of acquired security updates as well as the system configuration to secure it, like (in Windows) having Remote Registry enabled in services or Cortana , among many other things. And slightly older systems before Defender was part of Windows, if we're talking about Windows, had no factory installed anti-virus. But even with other OSes, the lack of updates is problem enough.

      • given the fact that the only 100% reliable way to 'disinfect' any compromised device is resetting it to factory settings

        Sounds like killing the patient to prevent the spread of an infectious disease. A factory reset is only necessary if you have no idea what you are dealing with. In this case, they probably had a very good idea of the nature of the payload, and were able to disable it without such drastic measures.

    • I am wondering how this can be legal.

      Oh, that's easy. If the police do this, it is a priori legal.

        That is probably what they want everybody to believe. But there are still some nations that are not police states (yet). In addition, this was the _French_ police. Whatever they do in, say, the US, the UK or some other (proto-) police states, is very much not legal there unless they have special permissions from the local police.

        Microsoft has informed every user about this and has permission via the TOU. The French police has just as much right to do anything like that outside of France as you or me.

            The deleting is an accident. These do happen. Unless there is gross negligence (good luck proving that, all of MS is basically gross negligence...), what MS has by the TOU and your acceptance of them is permission access your computer and to change files for the purpose of updates and security fixes.

    • I'm not sure that's true. A parallel could be drawn to litter. Or to a foreign object in the body. If you get shot and are unconscious, the medical professionals will go ahead and take the bullet out of your body, without even asking! How rude!

      On the other hand, if they did any damage while they were in there, you could sue.

      • by gweihir ( 88907 )

        Emergency powers like these are created by specific laws. Yes, medical professionals have the right to make decisions in your best interest if you cannot. Anybody directly helping in an emergency has them. For example you may always legally drag somebody unconscious for a burning building and you may even hurt them to some degree in that process if it is unavoidable. But there are limits. If I have a DNR (Do Not Resuscitate) Order in place, then medical professionals are not allowed to save me, for example.

    • They probably committed crimes in multiple countries as a result of their actions. However, part of law enforcement is enforcement. The justice system doesn't go after every crime; many cases are simply dropped. In most of the places where these crimes happened, that's likely what will happen: the justice system will decide not to pursue it.

      If any of these countries has a particular beef with France, they might think to use their legal system to retaliate, but many of these are smaller countries with not

      I accept that it is a bit of a grey area but I suspect their logic goes something like this:

      They are not removing the 'software' without the owner's permission. The owner, or more specifically the relevant software on the owner's computer, connected to their (by virtue of force majeure) server and requested instructions. That the instructions now say "delete yourself" rather than "perform a DDOS on 192.168.0.1" is immaterial to the fact that the owner did, albeit blindly, make the request, and hence granted

        a) The real bomb is actually in the jurisdiction of the cops that will take it away (or more likely blow it up remotely, along with your living room)
        b) Because of a) there are specific laws in existence that say they are allowed.

    Given that I'm accepting this story as a generally true and accurate account of what happened, I'm going to say this: I'm delighted that for once the police weren't just a bunch of low-brow, power-tripping thugs more interested in night-sticking non-violent environment activists than going up against violence-friendly, white supremacist skinheads. Brains and heart in the right place, and a minimum of violence. This is a good thing.

    This is what law enforcement should be all about.
