Protect your credentials from stealthy cyber threats
Cyberattacks aren’t just targeting large corporations anymore. Today, cybercriminals are coming after everyone. They’re using a specific type of malware called infostealers to quietly grab usernames, passwords, browser data, and login tokens from personal and business devices.
In fact, a recent report by Fortinet reveals that more than 1.7 billion credentials were stolen in 2024 alone. These were not old leaks — they were pulled directly from infected devices using active malware.
Credential Theft Is Now a Business
The rise of infostealer malware has changed the way hackers operate. Instead of launching large-scale data breaches, attackers are going after individuals. Their tools can extract browser passwords, email logins, crypto wallets, and even MFA (multi-factor authentication) session tokens — all without raising suspicion.
Once collected, this stolen information is sold on the dark web. Initial Access Brokers (IABs) bundle these logs and sell them to cybercriminal groups. This includes ransomware gangs looking for easy access to company systems.
Infostealers such as Redline, Vidar, and Racoon have become popular tools for this purpose. These programs are easy to use, widely available, and extremely effective.
How Infostealers Work
Infostealer malware is often spread through phishing emails, fake browser extensions, or cracked software. After being installed, it quietly searches your device for saved logins, autofill data, cookies, and session tokens. Many also hunt for FTP credentials, digital wallets, and cloud logins.
Even if you use multi-factor authentication, you might not be safe. Stolen session cookies allow attackers to hijack accounts without needing your password or a verification code.
Once the data is gathered, it’s uploaded to a remote server. From there, the attacker may use it themselves or sell it to others. The logs usually include IP addresses, device info, and complete credential sets — giving attackers everything they need.
How to Stay Safe from Infostealers
1. Use a Password Manager Instead of Your Browser
Most infostealers target browser-stored passwords. That’s why you should never rely on your browser to save logins. Instead, use a secure password manager like NordPass or 1Password. These tools store your credentials in an encrypted vault, away from prying eyes.
They also offer breach monitoring, password health checks, and secure sharing — all essential features in today’s threat landscape.
2. Enable Multi-Factor Authentication (MFA)
Even though MFA isn’t foolproof, it still adds a strong second layer of defense. Use an authenticator app or biometric method rather than SMS. Services like Okta or Microsoft Authenticator are great options.
Make sure MFA is turned on for your email, banking apps, cloud services, and work accounts.
3. Stay Away from Suspicious Downloads
Infostealers often disguise themselves as legitimate software. Avoid downloading cracked apps or plugins from unknown sources. Always use official websites or trusted app stores. Also, beware of phishing emails and fake popups that ask you to install updates or reset passwords.
To enhance your protection, install a reputable antivirus program. Consider options like Bitdefender, CrowdStrike, or Microsoft Defender for Business.
4. Keep Your Software Updated
Hackers take advantage of outdated software to spread malware. Regular updates fix security holes that cybercriminals might exploit. So, turn on automatic updates for your operating system, browser, and security apps.
Using patch management tools like NinjaOne or ManageEngine can also help businesses stay protected across all devices.
5. Use a Personal Data Removal Service
Your personal information is likely scattered across hundreds of websites. Data brokers collect and sell it — and attackers use it to launch targeted scams. That’s why services like Incogni and DeleteMe are useful. They scan the web, find your exposed data, and request its removal.
While no service can erase everything, they dramatically reduce your exposure — and that’s a major win for privacy and cybersecurity.
Final Thoughts
The massive leak of over 1.7 billion credentials proves one thing: cybercriminals don’t need a data breach to steal your passwords. All it takes is a single click on a malicious link or download.
By practicing smart cybersecurity habits and using trusted tools, you can stay several steps ahead of infostealers. Don’t wait until your credentials are up for sale. Take action today.
