Threats tagged 'jsceal'

JSCeal is a sophisticated cryptocurrency-focused stealer malware delivered as compiled V8 bytecode executed by a bundled Node.js runtime. It employs multiple layers of JavaScript obfuscation and encryption, including RC4 and AES-256-CBC, to protect its payload. The malware's capabilities include keylogging, browser credential theft, cryptocurrency collection, HTTPS traffic interception via a local man-in-the-middle proxy, and session replay using stolen cookies. Recent variants target macOS and newer V8 versions, showing active development. Check Point Research developed a fully static deobfuscation pipeline to analyze JSCeal without executing it, enabling detailed understanding of its behavior. The toolkit is publicly available and supports analysis of multiple samples.

A sophisticated malware campaign called JSCEAL is targeting cryptocurrency users through fake apps impersonating popular trading platforms. The attackers use malicious ads to lure victims into downloading installers that deploy a multi-stage infection chain. This includes PowerShell scripts for profiling and a final payload of compiled JavaScript (JSC) files executed via Node.js. The JSCEAL malware steals crypto-related data and credentials while employing advanced evasion techniques. The campaign has potentially reached millions of users across multiple countries, primarily targeting the cryptocurrency and financial sectors.
