Hey, gamers and alt-right trolls -- a new Discord piece of malware is coming to get ya!
Called "Spidey Bot" by its discoverers, the Windows malware injects itself into Discord's code and steals your username, email address, IP address, phone number and Discord user token.
The malware also copies the first 50 characters of your Windows clipboard, which might contain your password if you've copied and pasted it recently, and creates a "backdoor" so that more malware can be installed. Macs don't seem to be affected.
If you're not familiar with Discord, it's chat software often used by PC gamers that has also been picked up lately by people who've been kicked off Reddit and Twitter for particularly unsavory comments.
It's not totally clear yet how the Discord malware gets on your machine. Malware researcher Vitali Kremez suspects it's being passed around in Discord chats as cheats for Roblox and other games. Kremez told Bleeping Computer two files names he'd seen were "Blueface Reward Claimer.exe" and "Synapse X.exe".
Unfortunately, you won't be able to tell if your Discord application is infected. [UPDATE: It turns out you can -- see the end of this story.] Even if you do, you'll have to delete the Discord software and reinstall it to make sure you're clean. All you can do is make sure you're running the best antivirus software, which should block the malware.
Discord itself doesn't seem to be too helpful in responding to user concerns.
Unfortunately, there's not much any app can do to prevent something like this. However, you should always be cautious about clicking strange links and even more suspicious of downloading unknown software from unverified sources. Doing so could lead to things like this.October 24, 2019
Hi there, and sorry for the scare. This isn't actually an issue with the code, but it is on the user end. To protect yourself from this don't click on untrusted links and do not download and run programs from sources you do not know or trust.October 24, 2019
Sorry for the confusion there, this isn't a vulnerability. This is done by installing another program that modifies Discord on your computer. As long as you don't download any unknown or untrusted programs you should be a-okay!October 24, 2019
But sadly, Discord is right. There's not that much the software maker can do from its end at the moment, except maybe to tell people to access Discord on their phone or gaming console instead of on a PC or Mac.
UPDATE: Bleeping Computer updated its own article on Spidey Bot with a method by which Discord users can check to see if their Discord desktop installations have been infected.
Spidey Bot targets only two files in the Discord application folder:
Open each of these files in Notepad. Each should have only a single line of code. If either has more than one line, your Discord build is compromised and should be uninstalled.
Bleeping Computer also proposed that Discord perform a file-integrity check every time the application is launched to prevent against further compromise. That feature doesn't seem to exist in the application right now, but it wouldn't be hard to add in a future software update.
