Discord is a free online chat application where you can share data in text, audio and video formats. Due to its lightweight nature and flexibility, it is really popular among gamers.
Unfortunately, hackers can use Discord to spread malware. The most common type of malware in Discord is the Remote Access Trojan (RAT). Hackers usually distribute them via malicious links. When RATs are injected into your device, they gain administrative rights and can track your actions, steal data and manipulate your device. They can also install additional malware or make your computer part of the botnet for further virus dissemination.
Webhooks allow third parties to send messages to a Discord channel. Hackers can use them to create URLs to send messages. Webhooks are a popular method to withdraw data from a hacked user device. A hacker can sync webhooks with a corrupted system and extract the stolen data via Discord.
There are different forms of Discord malware, and each has its own way of spreading and infecting your devices.
This attack is particularly difficult to detect. Antivirus software will probably not recognize the corrupt code. However, if Discord detects that someone modified the files while it's updating, it warns the user and asks whether to continue to run the client. You can also check files manually for suspicious additions. You can find lots of info online on what to look for.
Spidey Bot is one of the most common type of corrupted Discord file. One way to check whether you have it is by opening the %AppData%\Discord\[version]\modules\discord_modules\index.js and %AppData%\Discord\[version]\modules\discord_desktop_core\index.js folders and checking how many lines of code they have. If there is more than one line, then the files have been compromised. At this point, however, the only remedy is to reinstall Discord and secure your Discord account or device.
Only download Discord from official sources or websites. This will minimize the possibility of getting a copy of Discord with malicious code.
As with most social apps, Discord can also be a source for malware. Even though the filtering of malicious files and warning users if they encounter one, improve Discord security, the platform does not recognize all of them – especially new ones.
Users may also upload a file to Discord and then use its link to share it externally. Even users with no Discord account can download it. Moreover, even if someone deletes the file from Discord or removed their account, the platform still stores it in its content delivery network. So no one can trace the original uploader of file with just a Discord download URL.
