What is an Infostealer?
An infostealer is a type of malware designed to stealthily extract sensitive information from infected devices. It operates in the background, collecting data such as login credentials, financial details, and personal information, which hackers can then use for identity theft, financial fraud, or selling on the dark web. These infections often spread through phishing emails, malicious downloads, or exploited vulnerabilities.

What to Do If You’ve Been Compromised
If the check reveals infostealer infections on your domain:
- Reset Credentials: Immediately change passwords and revoke access for any compromised accounts or systems.
- Enhance Security Protocols: Implement multi-factor authentication (MFA) across all company accounts and services.
- Scan and Monitor: Run thorough security scans on all devices and monitor network activity for ongoing threats.
Preventive Measures
To protect your company’s domain from future infostealer infections:
- Educate Employees: Train staff to recognize phishing attempts and avoid suspicious links or attachments.
- Use Strong Authentication: Enforce unique, complex passwords and consider password managers for secure storage.
- Keep Systems Updated: Regularly patch software and operating systems to close security gaps.
- Deploy Security Tools: Install advanced antivirus and endpoint detection software to identify and block malware.
Don’t Store Sensitive Data Insecurely
Avoid storing credentials or sensitive information in easily accessible locations like browsers or unsecured files, as these are prime targets for infostealers. Instead, use dedicated, encrypted tools like enterprise-grade password managers to maintain strong security hygiene.
