FormBook is categorized as malware, specifically spyware, with the capability to extract files and data from the user's device, apps, and even capture keystrokes and clipboard content. Additionally, it can intercept data entered by users, including information from web forms and login pages, prior to encryption.
FormBook, also known as xLoader, is a malicious software categorized as spyware, designed with the insidious purpose of infiltrating devices to pilfer files and data from various applications. Its damaging potential encompasses malware infections, file corruption and loss, stolen keystrokes, system performance issues, network connectivity problems, unauthorized access, and data theft.
The spyware operates across multiple platforms, including Windows, macOS, and Linux. It manifests through various symptoms such as unusual system performance degradation, frequent network connectivity issues, unexpected file corruption and loss, keystrokes and clipboard data interception, unauthorized access to sensitive information, and incidents of data theft.
FormBook functions by capturing screenshots and transmitting the acquired information back to the attacker. As a Malware-as-a-Service (MaaS), FormBook can have numerous variants, making it a versatile and adaptable threat.
If infected, it is crucial to take immediate action. Isolate the infected device from the network to prevent further spread, run a Gridinsoft Anti-Malware scan to detect and remove FormBook, review system logs for any suspicious activity, and identify compromised files. Additionally, restoring affected files and data from backups taken before the infection is recommended.
Preventing FormBook infections requires proactive measures. Regularly updating the operating system and software to patch vulnerabilities is essential. Employing a robust antivirus/anti-malware solution and keeping it up to date adds an extra layer of defense. Implementing intrusion detection and prevention systems helps identify and block malicious activities, while application whitelisting controls the execution of programs on the system. Monitoring network traffic for unusual patterns and connections is another crucial step in maintaining cybersecurity.
