Nova Stealer is a malware operating under the Malware-as-a-Service (MaaS) model, available for a low cost for a 30-day license. It is a modified version of the SnakeLogger malware designed to extract sensitive information from compromised systems. Its distribution primarily occurs through aggressive phishing campaigns targeting sectors such as finance, retail, and IT, especially in regions like Russia. Nova Stealer infiltrates systems via phishing emails disguised as legitimate documents and employs techniques like steganography and process hollowing to evade detection. It can harvest data including saved credentials, keystrokes, clipboard contents, screenshots, cryptocurrency wallet information, and session cookies from platforms like Discord and Steam. The stolen data is transmitted through channels such as SMTP, FTP, or Telegram APIs. The malware's developers offer additional services, including cryptors to bypass antivirus detection, and a Telegram group for promotion and technical support. The MaaS model lowers entry barriers for cybercriminals, enabling those with minimal experience to conduct sophisticated attacks. Organizations are advised to implement strong email security measures, educate employees on phishing recognition, and utilize endpoint detection and response solutions to monitor unusual activities. Regular updates to antivirus software and operating systems are also recommended to mitigate vulnerabilities.
