New Data: How ChangeNOW Helps Traders Swap in Just 1 Minute

Google’s Threat Intelligence Group (GTIG) is warning that a “new and powerful” 
iOS exploit kit, dubbed Coruna by its developers has been deployed on fake 
finance and crypto websites designed to lure iPhone users into visiting pages 
that can silently deliver exploits. For crypto holders, the risk is blunt: 
GTIG’s analysis shows the campaigns ultimately focused on harvesting seed 
phrases and wallet data from popular mobile apps. Coruna targets Apple devices 
running iOS 13.0 through iOS 17.2.1, bundling five full exploit chains and 23 
exploits. GTIG says it recovered the kit after tracking its evolution across 
2025, from early use by a customer of a commercial surveillance company, to 
“watering hole” attacks on compromised Ukrainian websites, and finally to 
broad-scale distribution via Chinese-language scam sites tied to a financially 
motivated actor it tracks as UNC6691. A Crypto Lure Designed For iPhones In 
the scam-wave phase, GTIG says it observed the JavaScript framework behind 
Coruna deployed across a “very large set” of fake Chinese websites largely 
themed around finance. One example cited by GTIG is a fake WEEX-branded crypto 
exchange page that tried to push visitors onto an iOS device—after which a 
hidden iFrame would be injected to deliver the exploit kit “regardless of 
their geolocation.” Related Reading: CFTC Chair Says Crypto Perps Approval Is 
Close — Why This Is Huge For Hyperliquid? The delivery mechanics matter 
because they blur the line between traditional phishing and outright device 
compromise: in GTIG’s telling, simply arriving on the booby-trapped page from 
a vulnerable iPhone was enough to begin the chain. The framework fingerprints 
the device to identify model and iOS version, then loads the appropriate 
WebKit remote code execution exploit and a pointer authentication (PAC) 
bypass. GTIG tied one WebKit RCE it recovered to CVE-2024-23222, noting it was 
addressed by Apple in iOS 17.3 on Jan. 22, 2024. At the end of the chain, GTIG 
says Coruna drops a stager it calls PlasmaLoader (tracked as PLASMAGRID) and 
describes it as focused less on classic surveillance features and more on 
stealing financial information. According to GTIG, the payload can decode QR 
codes from images stored on the device and scan text blobs for BIP39 word 
sequences, along with keywords such as “backup phrase” and “bank account”, 
including in Apple Memos, which it can then exfiltrate. Related Reading: 
Crypto’s Quietest Month In Nearly A Year — But Hackers Haven’t Gone Away The 
payload is also modular. GTIG says it can pull down and run additional modules 
remotely, and that many of the identified modules are designed to hook 
functions and exfiltrate sensitive information from common crypto wallet 
apps—among them MetaMask, Trust Wallet, Uniswap’s wallet, Phantom, Exodus, and 
TON ecosystem wallets such as Tonkeeper. The broader arc was also flagged by 
mobile security firm iVerify, which published its own findings around the same 
time as GTIG’s report. “And that’s exactly what happened again here, but on 
mobile devices. Phone OEMs do as good a job as anyone can do…” What Crypto 
Users Can Do Now Google says Coruna “is not effective against the latest 
version of iOS,” and urges users to update. If updating isn’t possible, GTIG 
recommends enabling Apple’s Lockdown Mode. GTIG also says it added the 
identified websites and domains to Google Safe Browsing to help reduce further 
exposure. For crypto-native users, the immediate takeaway is practical: mobile 
wallets sit at the intersection of high-value assets and high-frequency web 
traffic, which makes “visit-to-compromise” campaigns uniquely dangerous. 
GTIG’s reporting suggests the scam funnel wasn’t just about getting victims to 
connect wallets, it was about getting them onto the right device, on the right 
iOS version, so exploitation could do the rest. At press time, the total 
crypto market cap stood at $2.45 trillion. Featured image created with DALL.E,
