New Android Trojans Target Over 800 Apps
Security researchers at Zimperium have identified four new Android trojans — RecruitRat, SaferRat, Astrinox and Massiv — that target banking and social-media applications. The trojans together aim at credentials and transaction theft across more than 800 apps. The malware can actively hide on infected devices (for example by replacing app icons with transparent images), remain dormant to evade initial scans, download additional payloads later, and hide malicious code inside ZIP structures. Researchers observed distribution vectors including fake job portals and illegal streaming sites; one trojan mimics the HR service Hirex. Users are advised to avoid sideloading apps from unknown websites and to use official app stores such as Google Play or trusted alternatives like F‑Droid.
A multi‑trojan campaign affecting over 800 apps is a notable security incident that can harm user trust in mobile apps and app stores and may increase fraud and credential theft risks; however it is not directly a major industry policy or platform change.

AI-powered Android malware Rathat discovered requiring factory reset
Security researchers at Zimperium uncovered a new Android malware named 'Rathat' that disguises itself as legitimate apps, including a fake Google Chrome. It tricks users into granting accessibility permissions, then enables Wireless Debugging to gain ADB shell access, installing an AI agent that coordinates malicious actions such as stealing banking credentials, intercepting SMS, and capturing screen activity. The malware operates stealthily, evades uninstallation, and can wipe the device if detected. Over 162 infected apps have been found, primarily targeting Chinese payment apps like WeChat Pay and Alipay, but it poses a global threat. Google states that Play Store protections can detect Rathat, advising users to install only from official sources. Infected devices require a factory reset to remove the malware.
AI Godfather Hinton Urges FDA-Style Approval for AI Models
Nobel laureate Geoffrey Hinton, often called the 'Godfather of AI', recommends that AI models undergo an approval process similar to that of drugs before release. In a podcast, he suggested that AI companies should have to convince a regulatory authority of their products' safety, akin to the FDA's process, which he notes is costly and time-consuming. This comes amid warnings from Hinton, Yoshua Bengio, and 20 other AI experts about a possible 'intelligence explosion' where AI systems improve themselves, risking humanity's control. Hinton argues that exponential progress could lead to a drastic worsening within one or two years. His call for stricter regulation contrasts with the current US approach, which relies on self-regulation rather than binding rules, despite a letter from 1,400 researchers and requests from major AI companies like Anthropic and OpenAI for more oversight.
AI Fashion Advisor Prompt for ChatGPT and Claude
Prompt engineer Susanne Renate Schneider has developed a detailed prompt that turns AI tools like ChatGPT and Claude into personal fashion advisors. The prompt instructs the AI to avoid judgments on attractiveness or health, instead focusing on recommendations for cuts, fabrics, and colors based on user input such as size, favorite outfits, and occasions. Users can optionally upload photos, with caution advised regarding data privacy. The AI is instructed to ask up to ten clarifying questions and then produce a personalized style guide. The approach could serve as a foundation for a digital wardrobe. The prompt was shared in the t3n MeisterPrompter podcast.
