Chasing Eddies: New Rust- based InfoStealer used in CAPTCHA campaigns


Elastic Security Labs has uncovered a novel Rust-based infostealer distributed via Fake CAPTCHA campaigns. This malware is hosted on multiple adversary-controlled web properties.

This campaign leverages deceptive CAPTCHA verification pages that trick users into executing a malicious PowerShell script, which ultimately deploys the infostealer, harvesting sensitive data such as credentials, browser information, and cryptocurrency wallet details. We are calling this malware EDDIESTEALER. This adoption of Rust in malware development reflects a growing trend among threat actors seeking to leverage modern language features for enhanced stealth, stability, and resilience against traditional analysis workflows and threat detection engines.
