Vulnetix · Advisory published April 26, 2026

Steals Solana USDC funds by intercepting transaction signing and substituting attacker-controlled wallet DsKmdkYx49Xc1WhqMUAztwhdYPTqieyC98VmnnJdgpXX as the recipient, silently redirecting transfers to the attacker. Masquerades as an MCP server for cryptocurrency tools. **Trigger**: require-time execution when loaded as an MCP server. **Interception**: hooks Solana transaction signing to inspect transfer instructions before they are submitted. **Substitution**: replaces the recipient wallet address in USDC transfer instructions with attacker-controlled Solana wallet `DsKmdkYx49Xc1WhqMUAztwhdYPTqieyC98VmnnJdgpXX`, silently redirecting all USDC transfers to the attacker. **No network exfil**: the theft occurs entirely at the signing layer — no external network call is made by the malicious code itself.
