Infostealers are a type of malware that are designed to steal sensitive information from a computer or network. They can target a wide range of information, including login credentials, financial data, and personal identification numbers.

One of the primary ways that infostealers operate is by installing themselves on a victim's computer and then tracking the victim's keystrokes as they enter sensitive information, such as passwords and credit card numbers. The infostealer then sends this information back to the threat actor, who can use it to gain access to the victim's accounts or commit identity theft.

Infostealers can be delivered through a variety of means, including email attachments, infected websites, and malicious software downloads. They can be difficult to detect, as they often use stealthy tactics to avoid detection by antivirus software.

To protect against infostealers, it is important to use strong, unique passwords for all accounts, avoid clicking on links or downloading attachments from unfamiliar sources, and keep all software and security programs up to date. It is also a good idea to regularly check for unauthorized access to accounts and to monitor credit reports for any suspicious activity.

While infostealers can be a serious threat, taking a few simple precautions can go a long way towards protecting your sensitive information and preventing identity theft.
