These packages masquerade as legitimate tools for integrating with popular AI models like GPT-4 and Claude AI, enticing users with seemingly functional features. Once installed, they covertly download a file named JavaUpdater.jar from GitHub, which contains the JarkaStealer malware. If the Java Runtime Environment (JRE) is not present on the system, the malware will also download and install it from Dropbox to ensure its payload can execute. This deceptive approach exploits the trust users place in open-source repositories and leverages the widespread interest in AI tools to spread JarkaStealer effectively. Additionally, the malware can infiltrate systems through other common vectors like phishing emails, fake software updates, and malicious ads, further broadening its reach.
