Fake Apps: A New Threat to Mobile Users

Cybersecurity researchers have uncovered a sophisticated mobile malware campaign targeting both Android and iOS platforms. This campaign, codenamed SarangTrap by Zimperium zLabs, utilizes fake dating, social networking, cloud storage, and car service apps to steal sensitive personal data from unsuspecting users. The primary focus of this extensive campaign appears to be users in South Korea, but the threat is relevant to mobile users across Asia.

The Scope of SarangTrap

The SarangTrap campaign is notable for its cross-platform reach, affecting both Android and iOS devices. This extensive operation involves:
