Gallium

Gallium is an exploit/component name associated with the Coruna iPhone exploitation framework and with the 2023 iOS espionage campaign Operation Triangulation. Reporting in the provided content links Gallium to CVE-2023-38606, described as a hardware-focused weakness used to bypass Apple’s Page Protection Layer (PPL), affecting iOS versions roughly spanning 14.x through 16.6. Google and other reporting state that Coruna reused internal exploits named Photon and Gallium, and that these were previously used as zero-days in Operation Triangulation. Coruna is described as a 23-component iOS exploit toolkit targeting iPhones running iOS 13 through 17.2.1, combining WebKit memory-corruption flaws, sandbox escapes, privilege escalation, and PPL bypasses. In 2025, Coruna was reportedly observed in highly targeted operations, in watering-hole attacks by Russian-linked UNC6353 against Ukrainian iPhone users via compromised Ukrainian websites, and later in financially motivated campaigns by a China-linked cluster, UNC6691, using fraudulent cryptocurrency and finance-themed sites. One mention in the content also states that GALLIUM packed some payloads using different known and custom packers. High-confidence indicators directly mentioned include the exploit name Gallium, its linkage to CVE-2023-38606, and its association with Coruna and Operation Triangulation.
