PLASMAGRID

Also known asplasmagrid

PLASMAGRID is a designation associated with infrastructure used to operate the Coruna iOS exploit kit, a large-scale exploitation framework targeting Apple iPhone users. Coruna has been observed since February 2025 and has been described as comprising multiple exploit chains spanning numerous individual exploits affecting iOS 13 through 17.2.1. Activity linked to this infrastructure has included delivery through watering-hole compromises, scam and crypto-draining websites, and themed lure pages, indicating broad and opportunistic deployment rather than a single narrowly scoped campaign. PLASMAGRID-associated infrastructure has been tied to command-and-control and exploit delivery operations. Reported infrastructure traits include distinctive web-response patterns and Cloudflare-fronted hosting behavior that enabled clustering of suspected servers. Delivery activity has included dropper pages that load JavaScript components, initialize communications with backend API endpoints, and render hidden iframe content to trigger exploit delivery. Additional linked lure infrastructure has used topical themes, including Iran war-related messaging, while earlier observed operations included compromised Ukrainian websites and Chinese scam sites. The available reporting supports PLASMAGRID as an infrastructure cluster or operational label connected to exploitation and post-delivery control of Coruna rather than a clearly attributed nation-state or formally named intrusion set. The observed use cases span surveillance-related deployment, watering-hole exploitation, and financially themed scam ecosystems, so a single actor identity, origin, or dominant motivation cannot be established with high confidence from the available facts alone.

Aye-Coruna: Tracing the iOS Exploit Kit from Ukraine to Iran War Lures | Validin

Activity cluster operating Coruna-related command-and-control (C2) infrastructure for an iOS exploit kit campaign. The content describes large-scale infrastructure mapping via historical DNS and HTTP response fingerprinting, with C2 domains often using Cloudflare, returning distinctive small (e.g., 32-byte) responses and ‘404 Not Found’ banners, and being linked to exploit delivery (dropper) pages that load offscreen iframes and initialize ‘LaSDK’ to contact C2 endpoints (e.g., https://<domain>/x).
