The XWorm malware is identified as a threat from the Remote Access Trojan (RAT) category. RATs are specifically designed to enable unauthorized access and control of a victim's computer by cybercriminals. With the use of RATs, attackers can remotely monitor and observe user activities, pilfer sensitive data, and execute a wide range of malicious operations on the compromised system, depending on their specific goals. According to researchers, the XWorm RAT is offered for sale by its developers at a price point of $400.

The XWorm RAT Can Steal a Wide Range of Sensitive Information

XWorm RAT possesses an extensive array of capabilities that make it a highly sophisticated and dangerous threat in the hands of cybercriminals. One of its primary functionalities is the ability to steal valuable system information from the victim's computer stealthily. The RAT can steal sensitive data from popular browsers. XWorm can extract passwords, cookies, credit card details, bookmarks, downloads, keywords, and browsing history from Chromium browsers. Similarly, it can pilfer passwords, cookies, bookmarks, and history from Firefox browsers, greatly compromising the security of the victim's online activities.

Moreover, XWorm's capabilities encompass targeting a variety of applications and services. It can steal Telegram session data, Discord tokens, WiFi passwords, Metamask and FileZilla data. Additionally, XWorm can access the Registry Editor, log keystrokes, run ransomware to encrypt files and demand a ransom, and manipulate clipboard data, services and processes.

Beyond information theft, XWorm has the capability to execute files, granting attackers the power to run various malicious programs and payloads on the compromised system. Additionally, the Trojan can gain unauthorized access to the victim's webcam and microphone, posing a significant invasion of privacy and allowing attackers to monitor the victim's activities. XWorm's reach extends even further as it can open URLs, execute shell commands, and manage files, effectively giving attackers complete control over the victim's computer.

The attackers can even use XWorm to enable or disable critical system components and features such as User Account Control (UAC), Registry Editor, Task Manager, Firewall and system updates. The ability to invoke the Blue Screen of Death (BSoD) adds another layer of disruption and potential damage to the victim's system.

The XWorm RAT Could Be Used to Deliver Ransomware Payloads on the Breached Devices

One significant capability of XWorm is its ability to conduct ransomware attacks. Ransomware is threatening software that encrypts files, making them inaccessible without a specific decryption key. Subsequently, XWorm's operators can demand payment from the victim in exchange for providing the necessary decryption software to regain access to the encrypted files.

In addition, XWorm has been observed being utilized by cybercriminals for clipboard hijacking. This technique involves malware monitoring and intercepting data copied to a victim's clipboard, with a specific focus on replacing cryptocurrency wallet addresses. For instance, if a victim copies a Bitcoin, Ethereum, or other cryptocurrency wallet address, XWorm detects the data and replaces it with a wallet address owned by the cybercriminals. Consequently, victims unwittingly send their funds to the hackers' wallet instead of the intended recipient's address.

The expansive range of malicious capabilities observed in the XWorm RAT also includes a keylogging functionality. Keylogging involves the harmful process of clandestinely capturing and recording all keyboard inputs made by a user on an infected system. This means that passwords, login credentials, sensitive messages, and other personal information are surreptitiously recorded and transmitted to the attacker's Command and Control server.
