How to Protect Your Data from Infostealers?
Cybersecurity threats, such as infostealers, pose daily risks to both individuals and organizations. These malicious programs can steal login credentials, credit card numbers, and other sensitive data. Just one click can result in your data being permanently compromised.

What Are Infostealers?
Infostealers are silent threats that target the data stored on your devices. The most common ways they infiltrate your system include:
- Phishing emails: Links or attachments containing malware.
- Illegally downloaded software: Pirated apps that contain hidden malicious code.
Infostealers operate covertly, without your knowledge. Once they capture sensitive data, they send it to attackers. For individuals, this can mean financial loss or identity theft, while for businesses, it could lead to data breaches, reputational damage, or ransomware attacks.
Simple Steps to Protect Your Data
- Trust only verified emails and attachments. Avoid opening suspicious files from unknown senders.
- Don’t use pirated software. Illegal programs are a common source of hidden spyware.
- Keep software up to date. The security of your devices depends on having the latest security patches.
- Use strong, unique passwords. Simple or reused passwords are easily cracked.
- Be cautious when clicking on links. Don’t open unknown or suspicious links received via email or pop-ups.
Multi-Factor Authentication: A Simple Way to Enhance Protection
A password alone isn’t enough. A powerful tool to prevent stolen credentials is multi-factor authentication (MFA). This involves combining several verification steps (e.g., a password + fingerprint or a one-time code) to protect your accounts more effectively.
- MFA boosts security: Even if an attacker gets your password, the additional verification step stops them.
- Protects sensitive systems: Safeguards both business data and personal accounts.
- Easy to use: Modern authentication methods are quick and user-friendly.
ProID: A Tool for Modern Access Protection in Organizations
ProID platform is a comprehensive product suite designed to secure access and help you:
- Passwordless login – ProID enables password-free login through two-factor authentication based on mobile devices (ownership) and biometric data.
- Support for nameless authentication via QR code, eliminating the risk of login credential theft by infostealers.
- Prevent unauthorized access attempts from the start.
- Protect devices even if lost or stolen – without two-factor verification, the devices remain unusable.
- Create qualified electronic signatures in compliance with eIDAS regulations.
- Cover scenarios linked to physical identity (access to buildings, printers, cafeterias, elevators, and controlling various devices, from medical to manufacturing).
