Experience targeted web-fraud protection with 詐欺ウォール Internet SagiWall, developed by BB Softservice corp., designed to block phishing, fake stores, and one-click scam pages. The app integrates a Safari extension plus an AI-and-heuristics Triple Detection Engine that flags suspicious pages in real time. It also offers an in-app secure browser, contextual warnings in Safari, and automatic blacklist updates. Intended for Japanese online shoppers, elderly users, and family devices, it reduces successful social-engineering attacks on iPhone users.

How the app detects Japanese web scams

Triple Detection Engine combines blacklist matching, heuristic analysis, and machine learning to identify fraudulent pages, with an emphasis on Japanese-language phishing, fake e-commerce, and one-click billing scams. The engine inspects site structure and behavior, matches known bad URLs, and raises alerts when billing flows or page elements look suspicious. That approach addresses site-based fraud that bypasses file-focused antivirus scanners.

Minimal impact on device performance during background checks

The tool runs as a Safari content blocker and a background service, and the developer designed it to keep battery and CPU use low. Protection is applied without switching apps by using the browser extension, although extension functionality requires iOS 15 or later. Using the app's secure browser keeps detection activity separate from the main browsing thread, which helps maintain normal browsing responsiveness.

Safety measures reduce accidental exposure to phishing pages

Miyabull displays a prominent warning screen when a site is flagged and offers a dedicated secure browser to isolate risky sessions. Automatic updates to the blacklist and detection logic help the app adapt to new scams. Integration with a national carrier ecosystem increases distribution and support for many users inside that network, which can simplify deployment for customers tied to those services.

No specialist knowledge required for basic protection

Enable the Safari extension to activate blocking and rely on clear, binary warning screens that guide less technical users, such as older adults. Users note the browser-level integration and explicit alerts make it straightforward to avoid risky links. For everyday use the app emphasizes simple blocking decisions rather than requiring detailed configuration, which suits households where a technical administrator is not available.

A practical choice with device-count trade-offs

Miyabull is a practical option for iPhone users in Japan who need site-level fraud blocking for social-engineering attacks. Allocate a single license across critical family devices, since a license typically covers up to three devices. Main caveat: larger households require extra device planning. Assign protection first to the most at-risk phones, such as older family members and frequent online shoppers.
