Summary

Hide ▲

The Coruna iOS exploit campaign spread through watering-hole and fake finance/crypto lures, extending reach from iPhone users to crypto users. UNC6353 used the framework against compromised Ukrainian websites in summer 2025, and UNC6691 later tied it to fake gambling and crypto sites in late 2025. The shift matters because the same exploit kit was reused across espionage and financial theft operations, broadening the risk to ordinary mobile users. The kit also selected exploit chains by device fingerprint and could stop when Lockdown Mode or private browsing was enabled.

    Coruna iOS exploit kit linked to espionage and crypto theft

    Initial Disclosure

    Coruna is a previously undocumented iOS exploit kit with 23 exploits and five full exploit chains that affected iOS 13.0 through 17.2.1 and included CVE-2024-23222. GTIG first observed related activity in February 2025, later saw UNC6353 use the same framework in summer 2025 watering-hole attacks against iPhone users visiting compromised Ukrainian websites, and attributed late-2025 activity on fake Chinese gambling and crypto websites to UNC6691. Google added identified sites and domains to Safe Browsing and recommended updating iOS or enabling Lockdown Mode.
