In today’s digital landscape, cybercriminals are no longer just targeting large corporations; they’re coming after everyone. The rise of infostealer malware has made it easier for these malicious actors to steal sensitive information from ordinary users.
The Alarming Surge of Infostealer Malware
Recent research reveals a shocking 500% increase in infostealer activity over the past year, resulting in the theft of over 1.7 billion credentials. These figures highlight the growing threat posed by infostealers, which are specifically designed to extract sensitive data like usernames, passwords, browser cookies, email logins, and even crypto wallet information from individual devices.
Unlike traditional data breaches that compromise centralized databases, infostealers operate on personal machines, often without the user’s knowledge. This method means that anyone using the internet is at risk, particularly if they have saved passwords or sensitive information on their devices.
The Dark Web Market for Stolen Data
The data collected by infostealers is typically sold on the dark web by initial access brokers. These intermediaries provide compromised credentials to other cybercriminal groups, including those who operate ransomware schemes. Today, users can purchase access to corporate VPNs, admin dashboards, and personal bank accounts with verified functionality, all at region-specific prices.
According to Fortinet’s 2025 Global Threat Landscape Report, the most prevalent infostealers include RedLine, Vidar, and Raccoon. These programs are often distributed through phishing emails, malicious browser extensions, and fake software installers, making it essential for users to be vigilant about their online activities.
The Mechanism of Infostealer Attacks
Once installed on a device, infostealers can quickly scan for saved passwords, autofill records, and other sensitive information stored in local files. They are capable of exfiltrating session tokens and authentication cookies, putting even users who have enabled multifactor authentication (MFA) at risk. With a stolen session token, attackers can bypass MFA, gaining full control of a user’s online session without needing to log in manually.
After collecting the data, infostealers upload it to a command and control server, where it can be used directly by attackers or sold in bundles. These logs often contain extensive information about the victim, including their IP address, geolocation, browser fingerprint, and a complete list of credentials, providing attackers with everything they need for further exploitation.
Protecting Yourself Against Infostealer Malware
As the threat from infostealer malware continues to grow, it is crucial to adopt smart security practices to safeguard your information. Here are five effective strategies to help protect your data:
1. **Utilize a Password Manager:** Rather than relying on your browser to store passwords, consider using a dedicated password manager. Many of them come equipped with a built-in Data Breach Scanner that alerts you if your information has been compromised.
2. **Enable Two-Factor Authentication (2FA):** 2FA adds an extra layer of security by requiring a second form of verification, such as a code from an authentication app. This means that even if your credentials are stolen, attackers cannot access your accounts without the second factor.
3. **Invest in Reliable Antivirus Software:** Strong antivirus software can help protect your devices from infostealer malware, phishing emails, and malicious downloads. Always download software from trusted sources and double-check links before clicking.
4. **Keep Software Up to Date:** Cybercriminals often exploit vulnerabilities in outdated software. Regularly update your operating system, browsers, and security software to ensure you are protected against known threats.
5. **Consider Personal Data Removal Services:** These services can assist in removing your personal information from data broker sites, reducing your risk of identity theft and targeted scams. While not foolproof, they can significantly minimize your online footprint.
Conclusion: Remain Vigilant in a Digital World
The staggering 1.7 billion passwords leaked in 2024 reflect a rapidly evolving cybercrime landscape that preys on unsuspecting users. If you’ve ever saved a password in a browser, downloaded unofficial apps, or clicked on suspicious links, your credentials might already be compromised.
