HN Cloud on the 24th released the results of 2025 cyberattack detections analyzed through its mobile app security service "HN AppGuard (AppGuard)."
HN AppGuard is a cloud-based protection service that provides fraud detection and security threat response for Android- and iOS-based mobile apps, offering professional security features such as code obfuscation, memory tampering prevention, and app integrity verification.
According to HN Cloud, from January to September 2025, a total of 1.09 billion cyberattacks were detected across some 1,400 apps that adopted HN AppGuard, a 1.5-fold increase from the same period a year earlier (740 million).
The attack type that accounted for the largest share this year was "emulator," with 221 million detections, or 20.1% of the total. This is a 23% increase from a year earlier. Detections of "macro (auto click)" surged 93% to 191.5 million, and "tampering" attacks that attempted memory manipulation or code modification rose 90% to 162.9 million.
HN Cloud analyzed that the commercialization and sophistication of cheating tools have lowered the entry barrier to cyberattacks, which is the main reason for the increase in attacks. The company projected that such attacks will become even more frequent going forward.
Even so, it said many clients are improving security vulnerabilities and blocking attacks through HN AppGuard. HN AppGuard is software as a service (SaaS) that allows immediate application of the latest security features without server setup or separate installation, and more than 80% of clients maintain long-term use.
An HN Cloud official said, "As security incidents and mobile app abusing cases increase at home and abroad, interest in HN AppGuard is growing," and added, "Through continuous updates and powerful SaaS security features, we will help solve mobile security problems faced by clients in various sectors, including gaming, finance, and the public sector."
