Beware of Fake ChatGPT Apps That Spy on Users and Steal Sensitive Data

The proliferation of artificial intelligence applications has created unprecedented opportunities for cybercriminals to exploit user trust through deceptive mobile apps.Mobile app stores today are flooded with hundreds of lookalike applications claiming to offer ChatGPT, DALL·E, and other AI services.Security researchers have discovered that beneath polished logos and promises of advanced functionality lies a dangerous reality: not all clones are benign.Some serve as harmless API wrappers, others function as adware monetization schemes, and the most dangerous variants conceal sophisticated spyware capable of comprehensive device surveillance and credential theft.Recent security analysis reveals that brand impersonation has become the newest attack vector targeting both consumers and enterprises relying on mobile AI applications.According to SensorTower’s 2025 State of Mobile Report, AI-related mobile applications collectively generated 17 billion downloads in 2024, representing approximately 13 percent of all global app downloads.This explosive growth has attracted opportunistic developers who clone interfaces and branding of legitimate AI tools to deceive unsuspecting users.The threat landscape extends beyond simple imitation, encompassing a spectrum of malicious activities ranging from invasive data collection to full-featured malware frameworks capable of hijacking devices and stealing authentication credentials.The Three Tiers of Mobile App ThreatsSecurity researchers have identified distinct categories of cloned AI applications, each presenting varying levels of risk to users and organizations.The first tier comprises unofficial wrappers that transparently connect to genuine APIs without deception. While these applications present minimal security risks, they still raise concerns regarding privacy and brand confusion among end users.Examples include ChatGPT wrapper applications that openly acknowledge their unofficial status while providing legitimate access to OpenAI’s services.The second tier encompasses brand impersonators that exploit recognizable logos and interfaces to generate advertising revenue.A detailed technical analysis examined an application falsely branded as “DALL·E 3 AI Image Generator” hosted on third-party app stores.Despite presenting itself as an OpenAI product with claims of AI-powered image generation capabilities, the application contained no legitimate functionality whatsoever.Instead, the malicious app established exclusive network connections to advertising and analytics services including Adjust, AppsFlyer, Unity Ads, and Bigo Ads.Technical inspection revealed the package name deliberately mimicked OpenAI’s branding, contained embedded Gmail addresses and API keys, and was hastily assembled from template code.The application essentially functioned as a commercial parasite, monetizing user data and ad impressions through elaborate deception.WhatsApp Plus and Trojan FrameworksThe third and most dangerous tier represents fully-weaponized malware frameworks designed for comprehensive surveillance and credential theft.Security analysis of an application disguised as “WhatsApp Plus,” an unauthorized messenger variant, revealed a critical-level threat employing sophisticated obfuscation techniques.The malware utilized fraudulent certificates rather than legitimate Meta signing keys and employed the Ijiami packer, a tool commonly used by malware authors to encrypt malicious code.Upon installation, hidden executables within a folder named “secondary-program-dex-jars” remain dormant until decrypted and loaded, a characteristic hallmark of trojan loader functionality.Once activated, the WhatsApp Plus malware silently requests extensive device permissions enabling access to contacts, SMS messages, call logs, and account information.These privileges allow attackers to intercept one-time passwords, scrape address books, and impersonate victims within messaging applications.Embedded native libraries maintain persistent background execution long after application closure.Network analysis confirmed the malware employs domain fronting techniques, masking malicious traffic behind legitimate Amazon Web Services and Google Cloud endpoints—a sophisticated evasion method previously observed in spyware families including Triout and AndroRAT.The proliferation of deceptive AI applications poses significant risks to organizational security posture, regulatory compliance, and brand integrity.Enterprises must implement continuous monitoring solutions capable of detecting cloned applications across global app stores, conducting automated vulnerability assessments, and providing real-time security visibility.Security teams require unified platforms delivering contextual remediation guidance and integrated ticketing systems enabling rapid threat response.As mobile AI adoption accelerates, organizations cannot afford to rely solely on traditional app vetting mechanisms—proactive, continuous monitoring represents the only effective defense against evolving post-launch threats.Follow us on Google News, LinkedIn, and X to Get Instant Updates and Set GBH as a Preferred Source in Google.
