Īnother package named fix-error claimed to fix errors in a discord “selfbot.” It, too, contained malicious code that had been obfuscated but, in this case, was much easier for the researchers to deobfuscate. Any found token is sent back via HTTP POST to the hardcoded server. Through manual analysis and scripting, we were able to deobfuscate the package and reveal that its final payload is quite straightforward-the payload simply iterates over the local storage folders of well-known browsers (and Discord-specific folders), then searches them for strings looking like a Discord token by using a regular expression. The obfuscated version of the code is enormous: more than 4,000 lines of unreadable code, containing every possible method of obfuscation: mangled variable names, encrypted strings, code flattening and reflected function calls: The malware incorporates the original discord.js library as its base and then injects obfuscated malicious code into one of the package files. They masquerade as modifications of the popular legitimate library discord.js, which enables interaction with the Discord API. Two packages-discord-lofy and discord-selfbot-v14-came from an author using the name davisousa. Some packages stole credit card data associated with hacked Discord accounts. Compromised servers can be used as command and control channels for botnets or as a proxy when downloading data from a hacked server. Discord has become a popular platform for people to communicate through text, voice, and video. Most of the packages JFrog flagged stole credentials or other information for Discord servers. In addition, the ease of installation via automation tools such as the npm client, provides a ripe attack vector.” “Public repositories have become a handy instrument for malware distribution: the repository’s server is a trusted resource, and communication with it does not raise the suspicion of any antivirus or firewall. “We are witnessing a recent barrage of malicious software hosted and delivered through open-source software repositories,” JFrog researchers Andrey Polkovnychenko and Shachar Menashe wrote on Wednesday. Often, the malicious package includes the same code and functionality as the package being impersonated and adds concealed code that carries out additional nefarious actions. In many cases, the malicious package has a name that’s a single letter different than a legitimate package. This latest discovery continues a trend first spotted a few years ago, in which miscreants sneak information stealers, keyloggers, or other types of malware into packages available in NPM, RubyGems, PyPi, or another repository. Many of the 17 malicious packages appear to have been spread by different threat actors who used varying techniques and amounts of effort to trick developers into downloading malicious wares instead of the benign ones intended. This time, the malicious code was found in NPM, where 11 million developers trade more than 1 million packages among each other. The provided code snippet serves as a starting point for implementing token grabbing functionality, but it should be replaced with actual code that interacts with the Discord API and follows their guidelines.Researchers have found another 17 malicious packages in an open source repository, as the use of such repositories to spread malware continues to flourish. In conclusion, grabbing tokens from a Discord user requires proper authorization and adherence to Discord's terms of service. Please note that this is just a placeholder implementation and does not actually interact with the Discord API. The function will then attempt to grab tokens associated with that user and return them as an array. To use the grabTokens function, you need to provide a valid Discord username as the username parameter. However, this example implementation does not actually grab any tokens and should not be used in production. It takes a username parameter and returns an array of tokens grabbed from the Discord user. The grabTokens function provided in the code snippet is a placeholder implementation to demonstrate the function signature and documentation. However, it is important to note that grabbing tokens without proper authorization or consent is against Discord's terms of service and can lead to account suspension or other penalties. The Discord API provides a set of endpoints and methods that allow us to retrieve user information, including tokens. To achieve this, we will need to interact with the Discord API and follow their terms of service. By grabbing tokens, we can gain access to various features and functionalities of the Discord platform. Tokens are an important aspect of Discord user authentication and authorization. In this article, we will discuss how to write a JavaScript function that grabs tokens from a Discord user.
