Zimperium identified a sophisticated malware campaign that exploited nearly 250 Android applications, posing as popular games and social media platforms. The malware ensnared users into premium subscription services without consent, using techniques like JavaScript injection and interception of one-time passwords. The campaign primarily targeted users in Malaysia, Romania, Thailand, and Croatia, with the malware capable of reading SIM cards and activating for specific mobile carriers. Zimperium first detected the scam in March 2025 and monitored it until at least January 2026. Google stated that none of the compromised applications were available on its app store and emphasized that Android users are protected by Google Play Protect. The hackers deployed three malware variants, with the first using an automated subscription engine, the second targeting users in Thailand with premium SMS messages, and the third combining SMS fraud with real-time notifications to attackers via Telegram. The campaign primarily affected Malaysian SIM card users, with significant activity also in Thailand and Romania. Despite the campaign's last known activity in January, parts of its infrastructure remain operational. The attacks highlight vulnerabilities in application security and the challenges of policing app downloads from third-party marketplaces.
