Beware of Raccoon Stealer Malware
Raccoon Stealer Malware is a type of information-stealing malware that has been making headlines due to its active distribution and the extensive damage it can cause. It primarily targets sensitive data such as login credentials, credit card details, personal files, and more, making it a serious threat to both individuals and organisations. If you’re concerned about Raccoon Stealer, here’s a comprehensive overview, including how it works, how to protect yourself, and what to do if you are infected.
What is a Raccoon Stealer?
Raccoon Stealer is a malware variant that specializes in stealing personal and sensitive information from infected systems. Once it infects a machine, it gathers a variety of data, including but not limited to:
- Login credentials (e.g., usernames and passwords for websites, applications, and services).
- Financial data (credit card information, banking details).
- Browser data (cookies, saved passwords, browsing history).
- System information (including OS, IP address, and installed software).
- Files from user directories.
It is typically distributed via phishing emails, malicious ads, or infected websites and can be bundled with other malware.
How does Raccoon Stealer Work?

1. Initial Infection
- The most common method of infection is via malicious attachments in phishing emails or links to infected websites.
- Raccoon Stealer can also be distributed through cracked software or malicious software installers that appear to be legitimate applications.
2. Execution and Data Collection
- Once executed on a target system, Raccoon Stealer begins its operation by scanning for sensitive data. It typically focuses on web browsers (for saved passwords, cookies, etc.), email clients, and other common software.
- It can exfiltrate this data in real-time and send it back to a command-and-control (C&C) server managed by cybercriminals.
3. Data Exfiltration
- The malware sends the collected data back to the C&C server, which can then be sold on the dark web or used for other malicious purposes (like identity theft or fraud).
- It may also upload stolen data to cloud storage or FTP servers.
4. Persistence Mechanism
- Raccoon Stealer is designed to evade detection, often employing techniques like file obfuscation data encryption , and to remain hidden from antivirus software and other detection tools.
Signs of Raccoon Stealer Infection
- Unusual System Behavior: If your computer is running slower than usual, there may be a chance of malware running in the background.
- Suspicious Browser Activity: Unexpected logouts or requests for login credentials on websites where you are already logged in.
- Financial Irregularities: Unauthorized transactions or changes to bank accounts or online payments.
- Increased Network Traffic: You might notice higher-than-usual network usage, as the malware is sending collected data to a remote server.
How to protect yourself from Raccoon Stealery?
1. Use Antivirus and Anti-malware Software
- Regularly update your antivirus and anti-malware software to detect and block Raccoon Stealer and other threats.
- Enable real-time protection to prevent the execution of suspicious files.
2. Be Careful with Email Attachments and Links
- Avoid opening attachments or clicking on links from untrusted sources. Phishing emails often impersonate legitimate companies or services to trick users.
- Look out for email irregularities, such as spelling mistakes, suspicious sender addresses, or unexpected requests.
3. Use Strong, Unique Passwords
- Avoid using the same password across multiple sites. Use a password manager to store complex and unique passwords for every site or service.
- Enable two-factor authentication (2FA) for your online accounts, especially for critical services like banking, email, and cloud storage.
4. Regularly Update Software
- Keep Windows, browsers, and other software up to date to patch known vulnerabilities that Raccoon Stealer might exploit.
- Enable automatic updates whenever possible to minimize the risk of missing critical security patches.
5. Avoid Cracked Software or Pirated Content
- Cracked software is a common vector for malware, including Raccoon Stealer. Avoid downloading software from unofficial sources, as it may be bundled with malicious payloads.
6. Implement Endpoint Security
- Use firewalls and other security solutions (e.g., endpoint detection and response (EDR) tools) to protect your devices and network from unauthorized access.
- Monitor and analyze network traffic for signs of unusual activity, which may indicate a breach.
What to do if you are Infected with Raccoon Stealer ?
If you suspect or know that your system is infected with Raccoon Stealer, follow these steps:
1. Disconnect from the Internet
- Immediately disconnect from the network to prevent further exfiltration of data.
2. Run Antivirus/Anti-malware Scans
- Run a full system scan using trusted antivirus or anti-malware software (e.g., Malwarebytes, Bitdefender, or Windows Defender) to detect and remove the malware.
- Use specialized tools like RogueKiller or HitmanPro to remove advanced threats that may be harder to detect.
3. Change Passwords
- Change your passwords for sensitive accounts (banking, email, social media, etc.) from a clean device (not the infected one).
- Ensure that your new passwords are strong and unique.
4. Review Your Financial Transactions
- Check your bank and credit card accounts for unauthorized transactions or suspicious activity.
- Contact your bank immediately if you notice any irregularities.
5. Perform a Full System Restore (Optional)
- If your system is still compromised after cleaning, consider restoring it to a clean backup or reinstalling the operating system.
- Make sure to back up critical files before taking this step to avoid permanent data loss.
6. Monitor for Further Signs of Compromise
- Keep a close eye on any accounts that may have been compromised, and review security logs regularly.
- Consider implementing additional monitoring services for sensitive accounts.
Raccoon Stealer is a significant threat due to its ability to steal a wide range of sensitive information, including login credentials, financial data, and personal files. By adopting strong security practices, such as using antivirus software, practicing safe browsing habits, and enabling multi-factor authentication, you can reduce the risk of infection. In case of an infection, act quickly by disconnecting from the internet, running scans, and changing passwords to mitigate damage.
