The Resurgence of Raccoon Stealer: A Closer Look at the Evolved Malware-as-a-Service

Malicious actors are constantly finding new ways to exploit vulnerabilities and compromise sensitive data. Unfortunately, there are also underground criminal services making things easier.

One such instance is the recent return of Raccoon Stealer, a malware-as-a-service (MaaS) that has resurfaced after a 6-month hiatus, as discussed in a recent CyberInt blog. Since its debut in April 2019, Raccoon Stealer has gained notoriety for its affordability and user-friendly interface, making it a favored choice among cybercriminals. 

In this blog post, we delve into details of this revived threat, exploring its distribution methods, capabilities, and the measures organizations can take to defend against it.

Raccoon Stealer: A Brief Overview

Raccoon Stealer emerged on the cybercrime scene in April 2019 as a MaaS, allowing cybercriminals with minimal technical expertise to access and deploy a powerful tool for data theft. Its popularity lies in its cost-effectiveness and ease of use, catering to a wide range of malicious actors seeking to compromise valuable information.

Distribution Strategies: A Lack of Originality

One of the striking features of Raccoon Stealer is its absence of a unique distribution method. Cybercriminals primarily leverage well-established tactics to propagate the malware, including phishing emails, exploit kits, and malicious advertisements. The malware employs a loader to deliver its payload, often camouflaged as legitimate software updates or applications. This familiar approach aids in evading detection, making it imperative for users to remain vigilant when encountering unexpected software downloads.

Capabilities that Spell Danger

Once installed on a victim’s system, Raccoon Stealer exhibits a broad spectrum of capabilities, making it a potent threat to personal and organizational data. Some of its key functionalities include:

• Browser Data Theft: Raccoon Stealer can pilfer sensitive browser data, such as saved passwords, cookies, and autofill information. This enables cybercriminals to gain unauthorized access to various online accounts.
• Cryptocurrency Wallet Theft: Cryptocurrency enthusiasts should be wary, as Raccoon Stealer targets cryptocurrency wallets, potentially leading to significant financial losses for victims.
• System Information Harvesting: The malware is equipped to collect vital system information, providing attackers with insights that could aid in crafting more sophisticated attacks.
• FTP and Email Client Data: Raccoon Stealer extends its reach to FTP client data and email client information. This comprehensive approach underscores the malware’s intent to gather diverse data for exploitation.

The Adaptive Nature of Raccoon Stealer

The developers of Raccoon Stealer have demonstrated a proactive approach to refining their creation. Over time, they have introduced new features, enhanced stealth capabilities, and expanded the scope of data that the malware can harvest. This adaptability renders Raccoon Stealer a persistent and ever-evolving menace in the cybersecurity landscape.

Defending Against Raccoon Stealer and Similar Threats

As organizations brace themselves against the resurgence of Raccoon Stealer, several strategies can fortify their defenses:

1. Regular Software Updates: Keeping all software up to date, from operating systems to applications, can help plug known vulnerabilities that malware often exploits.
2. Employee Education: Providing employees with comprehensive training on recognizing phishing threats and practicing safe online behavior is crucial in thwarting initial infection vectors.
3. Advanced Threat Detection Solutions: Employing robust threat detection solutions bolstered by machine learning and behavioral analysis can identify and mitigate emerging threats like Raccoon Stealer.

The return of Raccoon Stealer serves as a reminder that the threat landscape is dynamic and ever-changing. As this MaaS evolves with new features and capabilities, organizations must adapt their cybersecurity measures to keep up with the pace of innovation in cybercrime. By remaining vigilant, educated, and armed with cutting-edge defenses, businesses can safeguard their sensitive data and ensure a secure digital environment for themselves and their customers.
