Reporting highlighted ongoing Android malware activity spanning banking trojans, spyware, backdoors, and data stealers, with campaigns relying on social engineering, fake apps, stealthy persistence, and evasion techniques that can bypass signature-based defenses. The write-up emphasizes that mobile threats increasingly use dynamic payload delivery and credential/financial data theft, reinforcing the need for stronger mobile security controls such as behavior-based monitoring, careful app sourcing, least-privilege permissions, and timely patching.
Separate analysis described the rise of AI-driven scraping against mobile apps, where attackers target the mobile API surface rather than the UI, leveraging the structured nature of API responses (e.g., predictable endpoints and clean JSON). The post outlines a common workflow—downloading an Android APK, reverse engineering it to extract endpoints and auth flows, and using runtime instrumentation in emulators or rooted devices with tools such as JADX, Frida, Ghidra, and APKTool—to automate data extraction at scale, highlighting that server-side systems often over-trust the client app and that traditional web anti-bot controls may not translate cleanly to mobile.

Zimperium published an overview of the Android threat landscape describing active banking trojans, spyware, backdoors, and data stealers using fake apps, social engineering, persistence, and evasion techniques. The report highlights growing risk to users and recommends safer app sourcing, permission controls, behavior-based monitoring, and prompt patching.
A Security Boulevard analysis says AI-driven automation has moved large-scale scraping from websites to mobile applications, with attackers focusing on mobile API endpoints rather than app user interfaces. It outlines common techniques including APK reverse engineering, runtime instrumentation, and automated replay of API calls to harvest structured data at scale.

Multiple mobile-focused threats were reported spanning **Android banking malware**, **iOS credential-harvesting via App Store listings**, and **Android espionage via trojanized crisis apps**. A new Android banking trojan marketed as **Mirax Bot** was advertised on underground forums as a **Malware-as-a-Service (MaaS)** offering, with claimed capabilities including **700+ app injects**, **Hidden VNC (HVNC)** for stealthy remote control, and features positioned for **account takeover (ATO)** and large-scale financial fraud; researchers noted the feature list is based on seller claims and not yet independently verified. Separately, researchers described **PromptSpy**, characterized as an Android threat that uses **generative-AI techniques** to improve phishing and fraud by generating more convincing social-engineering content and automating deceptive interactions on-device. In parallel, a phishing operation targeted iPhone users by impersonating **ChatGPT** and **Google Gemini** in emails that directed victims to **fraudulent iOS apps hosted on Apple’s App Store**; the apps (including *GeminiAI Advertising* `id6759005662` and *Ads GPT* `id6759514534`) presented a fake **Facebook login** flow to harvest credentials. Another campaign, **RedAlert**, weaponized a trojanized version of Israel’s “Red Alert” emergency app distributed as `RedAlert.apk` via **SMS phishing (smishing)**, pushing victims to sideload the APK; analysis reported the app mimicked the legitimate interface while requesting high-risk permissions (e.g., **SMS**, contacts, precise **GPS**) consistent with covert surveillance and data theft. A separate Kaspersky post focused on consumer guidance for disabling AI assistants and broader privacy concerns, and does not materially add incident-specific threat intelligence to the mobile malware/phishing reporting.

Security researchers reported a sophisticated iPhone exploitation framework dubbed **Coruna** that appears to have originated as a professionally developed, likely government-grade capability and later proliferated to foreign espionage and criminal actors. Analyses cited by Google’s Threat Intelligence Group and mobile security firm iVerify describe **five exploit chains** spanning **20+ vulnerabilities** affecting **iOS 13 through 17.2.1**, enabling delivery via malicious web content for device fingerprinting, remote code execution, and bypass of key iOS mitigations; the tool’s apparent usage trail includes alleged deployment by **Russian intelligence against Ukrainian targets** and subsequent adoption by a cybercrime group for cryptocurrency theft. Separate mobile-threat reporting detailed multiple **Android** campaigns and families emphasizing stealth, persistence, and credential theft. CloudSEK described a **RedAlert** trojanized app impersonating Israel’s Home Front Command alerting application, using a **multi-stage APK/DEX loader chain** (including an `assets/` payload) and UI mimicry while coercing high-risk permissions (e.g., Contacts, SMS, Location) and establishing C2. PolySwarm summarized **PromptSpy**, an Android RAT with VNC-based remote control that integrates **Google Gemini** to generate context-aware UI gesture instructions from screen XML dumps to improve persistence across device variants, distributed via a phishing site impersonating a bank portal and assessed as financially motivated (notably targeting Argentina). Zimperium separately profiled **ZeroDayRAT** as a modular Android spyware platform spread via social engineering and sideloading, supporting surveillance and financial theft (e.g., screen capture, keylogging, credential harvesting), underscoring continued escalation in mobile malware sophistication.

Reporting on mobile threats in 2025 highlighted sustained, high-volume malicious activity against Android devices, with **adware** dominating detections and a large number of **mobile banking Trojans** observed in the wild. Kaspersky’s telemetry-based review cited **14,059,465** blocked attacks involving malware/adware/unwanted software during 2025, **62%** of detections attributed to adware, and **815,000+** malicious installation packages identified, including **255,000** mobile banking Trojan packages; it also noted discovery of notable threats such as the **Keenadu** preinstalled backdoor, reportedly injected at the manufacturing stage by modifying `libandroid_runtime.so` to load into the address space of apps. Separate analysis of the Android **Massiv** malware described an active **mobile banking fraud** campaign delivered via a trojanized **IPTV app**, emphasizing the risk from apps sourced outside official stores. Massiv was reported to request extensive permissions and use **overlay** techniques to capture credentials and manipulate banking sessions, including monitoring user interactions and enabling fraudulent transactions with limited user visibility—reinforcing that mobile banking threats remain a material subset of the broader mobile malware ecosystem described in 2025 trend reporting.
