Beware of Malicious ChatGPT Apps That Record User Actions and Steal Sensitive Data
The rapid advancement of artificial intelligence has introduced unforeseen security challenges, notably the emergence of malicious applications impersonating legitimate AI tools like ChatGPT. Cybercriminals are exploiting the widespread popularity of ChatGPT by distributing counterfeit mobile applications designed to harvest sensitive user data and monitor digital activities without consent.
The Rise of Counterfeit ChatGPT Applications
Recent security analyses have uncovered sophisticated malicious apps masquerading as authentic ChatGPT interfaces. These fraudulent applications have infiltrated third-party app stores, targeting users seeking convenient access to AI-powered chatbots. By employing convincing branding techniques that mirror genuine ChatGPT interfaces—including recognizable logos and functional designs—these trojanized apps deceive users into believing they are interacting with legitimate software.
Once installed, these applications execute hidden surveillance routines while maintaining the appearance of functional AI assistants. This deceptive approach has led to millions of unsuspecting users worldwide downloading unofficial AI applications from unverified sources, thereby compromising their devices with embedded spyware.
Technical Analysis of Malicious ChatGPT Clones
Security researchers, including analysts from Appknox, have identified these malicious ChatGPT clones during comprehensive mobile security research examining AI-themed applications across various distribution platforms. Their findings reveal that threat actors are leveraging the trust associated with the ChatGPT brand to compromise user devices.
The analysis indicates that these counterfeit applications implement full malware frameworks capable of persistent surveillance and credential theft. Technical examinations have shown that network communications are masked through domain fronting using legitimate cloud infrastructure from providers like Amazon Web Services and Google Cloud. This sophisticated obfuscation technique allows malicious traffic to blend seamlessly with normal communications, effectively evading security detection mechanisms.
Infection Mechanism and Data Exfiltration
The deployment of malware begins with convincing app store listings featuring polished graphics and descriptions that promise enhanced ChatGPT functionality. Upon installation, these malicious applications request extensive permissions, including access to SMS messages, contact databases, call logs, and account credentials. These requests are designed to appear legitimate, thereby masking the true surveillance capabilities of the applications.
Further analysis has revealed code obfuscation techniques using tools like the Ijiami packer to encrypt malicious payloads. Decompiled packages have been found to contain folders labeled “secondary-program-dex-jars,” housing executables that decrypt after installation—a characteristic signature of trojan loaders.
The malware maintains persistence through embedded native libraries, ensuring that background execution continues even after users close the application interface. Network logs have demonstrated systematic exfiltration targeting one-time passwords, banking verification codes, and address book contents. Stolen credentials enable attackers to intercept multi-factor authentication processes and infiltrate corporate systems. Researchers have noted that these techniques parallel established spyware families, including Triout and AndroRAT.
Broader Implications and Related Threats
The exploitation of ChatGPT’s popularity is not limited to counterfeit mobile applications. Similar tactics have been observed in other domains:
– Malicious Chrome Extensions: Threat actors have been distributing malicious Chrome extensions masquerading as legitimate AI tools. These deceptive extensions target users seeking convenient access to services like ChatGPT, Claude, Perplexity, and Meta Llama, creating significant security risks for unsuspecting individuals and organizations. These fake extensions initially appear functional, allowing users to type prompts directly into the Chrome search bar, creating an illusion of legitimacy while secretly executing malicious operations in the background.

– Malicious PyPI Packages: A sophisticated supply chain attack targeting the Python Package Index (PyPI) involved malicious packages masquerading as AI chatbot tools to distribute a modified version of the JarkaStealer malware. These packages, named ‘gptplus’ and ‘claudeai-eng,’ cleverly mimicked tools for working with popular AI language models ChatGPT and Claude. Upon importing these packages, a hidden process would execute Base64-encoded data, downloading a JAR file containing JarkaStealer, capable of stealing browser data, capturing screenshots, collecting system information, and extracting session data from various applications.

– NodeStealer Malware: Facebook identified NodeStealer, a newly discovered malware that steals browser cookies, enabling threat actors to gain illicit access to various accounts on the platform, including Gmail and Outlook. This malware is distributed as a Windows executable file disguised as a PDF or Excel document, and upon deployment, it uses Node.js’ auto-launch module to append a fresh registry key to the victim’s device.

Recommendations for Users
To protect against these emerging threats, users are advised to:
1. Download Applications from Official Sources: Only install applications from official app stores and verify the developer’s authenticity before downloading.
2. Review App Permissions: Carefully examine the permissions requested by applications. Be cautious of apps requesting access to sensitive information without a clear need.
3. Keep Software Updated: Regularly update your operating system and applications to patch known vulnerabilities.
4. Use Reputable Security Software: Install and maintain up-to-date antivirus and anti-malware software to detect and prevent malicious activities.
5. Stay Informed: Keep abreast of the latest cybersecurity threats and trends to recognize potential risks.
By exercising caution and adhering to these best practices, users can mitigate the risks associated with malicious applications and safeguard their personal information from unauthorized access.
