Snake Infostealer: A Sophisticated Cyber Threat Targeting Facebook Users

In the ever-evolving landscape of cybersecurity threats, the emergence of the Snake Infostealer poses a significant risk to users, particularly those active on social media platforms like Facebook. This malicious tool, known for its Python-based architecture, has been employed by threat actors to pilfer sensitive information, including credentials, from unsuspecting victims. What sets Snake apart is its utilization of legitimate platforms such as Facebook, Discord, GitHub, and Telegram for propagation and data exfiltration, making it a formidable challenge for cybersecurity professionals to combat.

Details of the Campaign

The Snake Infostealer campaign first came to light in August 2023, with reports surfacing on a social media platform regarding its propagation through seemingly innocuous RAR or ZIP archive files. Upon opening these files, victims unknowingly trigger a series of downloaders, culminating in the execution of the information stealer from a GitLab repository controlled by the threat actor. Security experts have identified three distinct versions of the Snake Infostealer, with the latest variant compiled as an executable through PyInstaller, demonstrating a continuous evolution in the malware’s sophistication.

One of the notable aspects of the Snake Infostealer is its focus on extracting data from various web browsers, including the Vietnamese-centric Cốc Cốc browser, suggesting a targeted approach towards Vietnamese users. The stolen data, which encompasses credentials and cookies, is transmitted via the Telegram Bot API in the form of a ZIP archive. Of particular concern is the malware’s capability to extract cookie information associated with Facebook, indicating an intent to compromise and manipulate user accounts for malicious purposes.

The Snake Infostealer is not an isolated incident but rather part of a concerning trend of information stealers targeting Facebook cookies. Other notable threats in this category include S1deload Stealer, MrTonyScam, NodeStealer, and VietCredCare. These threats underscore the increasing sophistication and diversification of cyberattacks aimed at compromising user accounts and exploiting personal data for nefarious purposes.
