Racoon Stealer is a low-severity information-stealing malware campaign primarily classified as a keylogger and infostealer. It operates by leveraging multiple attack techniques consistent with the MITRE ATT&CK framework, including spearphishing attachments (T1193) to deliver the payload, execution via PowerShell (T1086) and command-line interface (T1059), and use of commonly used ports (T1043) for communication. The malware performs remote file copying (T1105) to exfiltrate data and compresses collected information (T1002) before sending it over its command and control (C2) channels (T1041). Automated collection techniques (T1119) and gathering data from the local system (T1005) are also employed to maximize data theft. Despite the absence of known exploits in the wild and a low severity rating, Racoon Stealer poses a risk by stealthily harvesting sensitive information such as credentials, personal data, and potentially financial information. The use of PowerShell and command-line interfaces indicates an ability to evade traditional detection methods, while spearphishing remains the primary infection vector, relying on user interaction to open malicious attachments. The campaign's technical details suggest moderate threat level but limited analysis data is available, indicating a need for further investigation and monitoring.

For European organizations, Racoon Stealer can lead to significant confidentiality breaches, especially if credentials or sensitive corporate data are exfiltrated. This can result in unauthorized access to internal systems, financial fraud, intellectual property theft, and reputational damage. Sectors with high-value data such as finance, healthcare, and government institutions are particularly at risk. The malware's use of common ports and PowerShell execution can bypass some network defenses, making detection challenging. Additionally, the spearphishing vector exploits human factors, which remain a persistent vulnerability. While the campaign is rated low severity, successful infections can cascade into more severe incidents if attackers leverage stolen credentials for lateral movement or further exploitation. European organizations with less mature email security and endpoint detection capabilities may face higher risks. The impact is compounded by the potential for data privacy violations under GDPR, leading to regulatory penalties and loss of customer trust.

To mitigate Racoon Stealer, European organizations should implement targeted measures beyond generic advice: 1) Enhance email security by deploying advanced anti-phishing solutions that analyze attachments and links for malicious content, including sandboxing and attachment detonation. 2) Enforce strict PowerShell logging and restrict execution policies to allow only signed scripts or block PowerShell usage where unnecessary. 3) Monitor network traffic for unusual activity on commonly used ports and implement network segmentation to limit lateral movement. 4) Deploy endpoint detection and response (EDR) tools capable of detecting command-line and script-based attacks. 5) Conduct regular user awareness training focused on spearphishing recognition and safe handling of email attachments. 6) Implement multi-factor authentication (MFA) to reduce the impact of credential theft. 7) Regularly audit and update incident response plans to include scenarios involving infostealers and credential theft. 8) Use data loss prevention (DLP) solutions to detect and block unauthorized data exfiltration attempts. These focused controls will reduce the likelihood of successful infection and limit the damage caused by Racoon Stealer.
