Hacked Launcher Minecraft

[Silvana Fleischacker]

Ihave found recently that Modded Minecraft versions 1.19+ crash with the use of 3rd party launchers such as Curseforge Launcher, ATLauncher and even when testing mods in MCreator. It refuses to open and returns an exit code of 1. I have tried deleting certain files, changing Java versions and attempting to update graphics drivers, all to no avail. Note that it doesn't matter what mods are installed. Even with none, it still fails to start. I can still play forge 1.19+ with the regular launcher and by downloading mods manually. I would greatly appreciate if I were to get help on this!

Paint_Ninja, I am sorry for not getting back sooner. I would like to tell you that it worked! I can now play modded minecraft once again. However, then it didn't work, but i just simply cleared and updated the drivers again. However, this happens often, so I've now checked "Download Drivers and Software when available" in AMD Software Adrenaline Edition. I would like to know if this is going to update drivers automatically, and prevent me from manually having to update them every few days myself. Again, thanks a tone for helping me out, it means alot!

I believe the option in amd software downloads it and then notifies you to install the update. Manually checking in amd software every few months or so would help you know for sure if it's fully automatic or not.

Hello again, I just want to say that I have "check for updates" set to automatic, and I have "download drivers and software" set to enabled, but still, after a few days the stoftware goes out of date and I'm forced to download them again manually. It's really tedious, and inconvenient to download them every few days. I want to add that no notification came up during those few days notifying me of any update. I checked AMD Software daily, and it said I was up to date. However, just today, Minecraft crashed once again and AMD Software failed to open, signaling that I had to clean and reinstall the graphics drivers.

The forum that you linked only provides steps for Windows 10, which I don't have. I've Windows 11. The tutorial says I need to run a program called Group Policy Edit, which I don't have (Only available on Windows 10 Pro it said), but now that I know that windows updates are downgrading the drivers, I'm going to try to research that for Windows 11, thanks again!

Am I correct in saying that selecting the "No" Option in device installation settings (to stop Windows from automatically downloading Manufacturers app, etc) will solve it? I've looked at a lot of tutorials about this, and this seems to be a common option.

ATLauncher is a simple and easy to use Minecraft Launcher which contains 155 modpacks for you to choose from, as well as the ability to browse and install packs from other platforms including CurseForge, Modrinth and Technic.

So why not take a look at the different packs that are available or just download ATLauncher and give a try yourself. If you're still unsure about us, then visit our about page to get a list of features.

Currently there are known issues with logging into Microsoft accounts. Check Downdetector for user reports of the issue.

This issue is intermittent over the last week, and affects all launchers and websites that use Minecraft services, including the vanilla launcher and minecraft.net.

This issue is at Microsoft/Mojang's end and is not something that ATLauncher or individuals themselves encountering issues can fix.

Some people have had luck using a VPN set to another country in order to login, but other than that all that you can do if you face login issues is to keep trying, logins start and stop working constantly, so just keep trying.

Again, please note that ATLauncher staff cannot do anything about this, please have some patience and just keep trying the above. Our support cannot do anything to fix this and will just direct you to the above.

Thanks

Unfortunately there is another exploit going around the modded Minecraft community at the moment.

This is an RCE which allows bad actors to run code remotely on your computer when connected on the same server as them.

The scope at the moment seems to mostly affect mods on 1.7 and 1.12 but may also occur on other Minecraft versions, there is still work going on to find a full list of mods and affected versions. If you play singleplayer only you don't have anything to worry about, only if you play online on public servers.

Due to the nature of this being a remote code execution exploit, any attacker on the same server as you could've run any code on your computer, so as such there's no way to tell if you've been affected or what code was run.

The best course of action currently if you play older modpacks on 1.7/1.12 is to simply not join any public servers unprotected and to add this mod to your instances to protect yourself from the exploit.

More information about the exploit and affected mods and solutions can be found at

There is a thread in our Discord if you have any questions.

NOTE: We posted this on our Discord when it happened, but forgot to post to our News feed, so if you already got the ping from our Discord about this issue, this is the same issue, not a new one.

The situation seems to have relaxed a bit, the details on the malware and what it does is known (again if you're interested take a look at this GitHub repo) and we have tools available to detect if you're infected:

- CurseForge Infected mods detection tool

- NekoDetector

Both these tools will detect for any traces of the malware on your PC or within your modded Minecraft installations (be sure to scan your entire drives, or at least your user folder and any folders where you run Minecraft from).

Several platforms have come out and confirmed that they've scanned and removed all traces (if there were any) of the malware from their sites:

- ATLauncher: All clear to install and use ATLauncher modpacks

- CurseForge: All clear to install and use CurseForge modpacks and install and use CurseForge mods

- Modrinth: All clear to install and use Modrinth modpacks and install and use Modrinth mods

- Technic: All clear to install and use Technic official modpacks. Non official modpacks were not verified as they use external download sources, so if you plan on installing a third party pack from Technic, you should be cautious and scan after downloading.

Make sure that you have scanned your system using the tools mentioned above before installing or playing Minecraft.

ATLauncher will be investigating how we can detect for and warn against this type of attack going forward, including checking not only for this specific type of malware, but also checking for changes to your mods since downloading. Keep an eye out for more updates on that in the coming week or two.

As always, if you have any concerns or questions, please reach out in #malware-incident channel in our Discord.

There is currently an ongoing incident within the Minecraft modding community where malware has been found to be included in some Minecraft mods (and bukkit plugins) on CurseForge. This included being included in some modpacks.

There are some smart people going through and finding out what the malware does, but at a high level it looks like it steals authentication credentials for Minecraft/Microsoft accounts that are logged into various launchers (not including ATLauncher), as well as stealing browser cookies and discord tokens as well as other things.

It self replicates itself, injecting a payload into any Minecraft mods in your system so that it can spread, and that's believed to be how it got onto CurseForge, unknowingly uploaded after the devs machines were infected.

Due to the fact that it can replicate itself into mods, it's highly likely that anyone who has been infected with the malware now has it injected into the mods on their system.

You can check if you're infected by using the detector tools released by CurseForge here.

The situation is still very much ongoing, and we'll be looking to place mitigations in place within the launcher to check for the presence of these infected mods as well as at the system level if you're infected. Will be looking to roll that out soon, again some smart people are looking into mitigations and what can be done to detect and remove the malware.

While more information is still being found out, for now the recommendation is to still not download any mods from anywhere which includes CurseForge, Modrinth and from any other sources, including friends.

If you have any questions or more information, please visit us in Discord in the #malware-incident channel.

Mojang have announced that on September 19th they will turn off login for unmigrated accounts. This will mean you'll no longer be able to login and play Minecraft.

We will remove legacy unmigrated account login from the launcher once Mojang have confirmed to have turned the login servers off.

If you still haven't migrated your account, please make sure you do so now so you don't lose access. If you're having troubles migrating or need help, take a look at Mojang's migration FAQ page.

When I try to connect to servers or join up on lan worlds in Minecraft it says "Failed to Login : Invalid session (Try restarting your game)". Multiplayer used to work fine but now keeps coming up with this error. Can anybody help?

Just as the error says your session ID, what you log in with, is invalid. This usually happens when you log in to your account and then have a new instance of minecraft and log in again without closing down the old one. The old session ID is invalidated as soon as the new connection is made. This will give you the error above when you attempt to log into a server as it will only have the new Session ID.
