The Growing Threat of Cybercrime

In today’s digital landscape, cybercriminals are no longer just targeting large corporations. The shift in tactics has resulted in an alarming surge in attacks on everyday internet users. At the forefront of this alarming trend is a type of malware known as infostealers, which are designed to silently siphon off sensitive information, including passwords, browser data, and login tokens.

A Disturbing Surge in Credential Theft

Recent findings from cybersecurity researchers at Fortinet reveal that the problem has escalated dramatically, with infostealer activity skyrocketing by 500% in just one year. In 2024 alone, over 1.7 billion new credentials were harvested, not merely from past breaches, but through ongoing infections on personal devices. This staggering increase underscores the urgent need for users to be aware of their vulnerabilities.

Understanding Infostealers

Infostealers are malicious programs specifically crafted to extract confidential information from individual machines rather than large centralized databases. They operate unnoticed, compromising end-user devices without raising any alarms. Unlike traditional data breaches, which often involve hacking into corporate servers, infostealers infiltrate personal computers and mobile devices, quietly collecting sensitive data.

After harvesting this information, the data is typically sold on the dark web by initial access brokers. These intermediaries trade compromised credentials and access tokens with other cybercriminal organizations, including ransomware operators. The marketplace for these stolen credentials has matured significantly, allowing access to anything from corporate VPNs to personal bank accounts, often with verified functionality.

The Alarming Statistics

Fortinet’s 2025 Global Threat Landscape Report highlights a staggering 500% increase in credential logs due to infostealer infections over the past year. Among the most dangerous infostealers identified are RedLine, Vidar, and Raccoon, which are prevalent in the underground market.

How Infostealers Operate

Infostealers commonly find their way onto devices through various means such as phishing emails, malicious browser extensions, counterfeit software installers, or pirated applications. Once installed, they scan the device for any stored credentials, including saved passwords, autofill data, and local files. Many infostealers also target digital wallets, FTP credentials, and cloud service logins.

A critical concern is that these malicious programs can exfiltrate session tokens and authentication cookies, rendering even users who employ multifactor authentication vulnerable. With a stolen session token, an attacker can bypass multifactor authentication entirely and take control of the session without needing to log in manually.

Protecting Your Data: Essential Strategies

As infostealer malware continues to pose a significant risk, it’s vital to adopt a combination of smart security practices and reliable tools. Here are five effective strategies to safeguard your information:

1. Utilize a Password Manager:
– Infostealers often target saved passwords in web browsers. Using a dedicated password manager can provide enhanced security. Look for one that includes a built-in Data Breach Scanner to identify if your information has been compromised.

2. Enable Two-Factor Authentication (2FA):
– Adding an extra layer of security through 2FA can significantly enhance your defense. Even if your credentials are stolen, 2FA requires a second form of verification, making it much harder for attackers to gain access.

3. Invest in Robust Antivirus Software:
– Strong antivirus software is essential for protecting your devices from malware. Be cautious with downloads from untrusted sources and always verify links before clicking. This can help catch phishing attempts and malicious software before they compromise your security.

4. Keep Software Updated:
– Regularly updating your operating system, browsers, and security software is crucial. Cybercriminals often exploit outdated software to deliver malware, so enabling automatic updates is a wise choice.

5. Consider a Personal Data Removal Service:
– These services assist in removing your personal information from data broker sites, significantly reducing your risk of identity theft and targeted scams. While they may come with a cost, the peace of mind they provide can be invaluable.

The Reality of Credential Leaks

The staggering figure of 1.7 billion leaked passwords in 2024 highlights a disturbing trend in the cybercrime economy. This crisis is fueled by unsuspecting users who may have unknowingly saved passwords in browsers, downloaded unofficial applications, or clicked on dubious links. The tools for cybercrime are more accessible than ever, and the implications for individuals can be devastating.

Who Should Bear the Responsibility?

As we navigate this complex landscape of cybersecurity threats, it raises an important question: Who should primarily be responsible for protecting personal and organizational data from cyber threats? Should it be individual users, companies, software providers, or government agencies? We invite you to share your thoughts on this critical issue.
