Code obfuscation makes it difficult to analyze and counter the insidious threat.

Security researchers at SonicWall have recently discovered a new piece of malware that targets Gmail accounts. Dubbed MalAgent.AutoITBot, the malware is distributed as an executable file named "File.exe" and uses a variety of tactics to compromise user data, including intercepting clipboard data, recording keystrokes, and potentially taking control of input devices.

Once launched, MalAgent.AutoITBot attempts to open the Gmail login page using the popular browsers: Microsoft Edge, Google Chrome, and Mozilla Firefox. However, the software's capabilities go far beyond accessing email accounts.

The main purpose of this bot is to steal data and manipulate the system. It is capable of recording keystrokes, reading clipboard contents, and even controlling keyboard and mouse input. These capabilities allow the malware to collect sensitive information such as usernames, passwords, and other important data.

In addition, MalAgent.AutoITBot can reboot or shut down the infected device, run processes on behalf of other users, and block user input when debugging tools are detected. This anti-analysis feature makes it difficult to understand malware and develop defenses, making it a major challenge for cybersecurity professionals.

Analysis of the program by the SonicWall team showed that the file was heavily obfuscated and used several network libraries with unclear identifiers. This confusion makes it difficult to understand the exact actions and intentions of malware.

After extracting the script, the researchers found commands that directed browsers to Gmail login pages via "accounts.google.com". However, the malware doesn't stop there: it also includes links to log in to popular social networks. This approach suggests that the bot is designed to steal credentials from a wide variety of online services, not just Gmail.

Particularly disturbing is MalAgent.AutoITBot's ability to run multiple processes undetected. For example, when Firefox is launched, the malware creates a hidden page in parallel while trying to establish a network connection. This stealthy behavior allows the virus to operate undetected, making it difficult for both users and traditional antivirus solutions to detect and neutralize.

Given all these possibilities, MalAgent.AutoITBot poses a serious threat to both private users and organizations. Its ability to steal credentials and manipulate system functions underscores the importance of being careful with files of unknown origin.
