Serpent Stealer is a lightweight, .NET-based malware that targets sensitive information, including login credentials and cryptocurrency wallet details. It operates by extracting data from browsers and applications and uses Discord webhooks for data exfiltration. Known for its stealth, Serpent Stealer can bypass security mechanisms such as Windows UAC and virtual machine detection.
Serpent Stealer is delivered as a 64-bit portable executable, designed to evade detection through sophisticated checks for virtual machines, debuggers, and specific usernames. Once active, it harvests data from web browsers, cryptocurrency wallets, and other applications. The malware then transmits the stolen data to the attacker via Discord webhooks, leveraging this platform's infrastructure to mask its activity.
Distribution and Stealth Mechanisms
First identified in October 2023, Serpent Stealer has been promoted on underground forums, where it is marketed with builder tools and customer support. Its distribution often occurs via phishing campaigns or bundled with other malicious software. The use of Discord webhooks not only aids in exfiltration but also adds a layer of obfuscation, making the malware more challenging to detect in network traffic.
Impact and Threat Landscape
Serpent Stealer represents a growing class of stealer-type malware that poses significant risks to both individuals and organizations. By targeting login credentials, cryptocurrency wallets, and other sensitive data, it has the potential to facilitate financial fraud and account takeovers. Its stealth features and user-friendly deployment tools underscore the evolving capabilities of modern malware.
