Researchers at Cyble, reported about the new ransomware family AXLocker, which not only encrypts victims' files and demands ransom payment, but is also capable of stealing the Discord accounts of infected users. When users enter their credentials and login to the Discord account, the platform sends back an authentication token saved on the computer, which then can be used for API requests that retrieve information about accounts or to log in as a user. Threat actors steal these tokens so that they take over the account and use them for malicious attacks. Moreover, Discord is used by many of the NFT platforms and cryptocurrency groups, so if the threat actor is able to steal a moderator token, he can conduct a scam and steal funds. Further, when Cyble analyzed AXLocker, it was found that, like ransomware, there is nothing particularly sophisticated about the malware used, and when executed it targets certain types of file extensions by excluding specific folders. Also, AXLocker uses the AES algorithm for encryption, but doesn't change filename extensions on the encrypted files so that they can keep their normal names. Additionally, AXLocker, using a webhook URL, sends a victim ID, system details, data stored in browsers, and Discord tokens to the threat actors' Discord channel. Moreover, AXLocker performs the scanning of the probable directories to extract tokens where it uses regular expressions. Finally, a pop-up window appears on the victim's system with a ransom note which informs them about the encryption of the file and how they can contact the threat actor to purchase a decryptor.
