Forensic narrative

@alxlpsc disclosed on medium that MetaMask has serious privacy leaks. The vulnerability mainly uses MetaMask to automatically load NFT image URLs. Basic attack idea: the attacker can set the URI of the NFT to a server URL that he can control, and transfer the NFT to the target account; when the user logs in to MetaMask, MetaMask will automatically scan the NFT owned by the account, and initiate a pointer to The HTTP request to the attacker's server; the attacker can obtain the victim's IP information from the access log. Attack method (per SlowMist): Information Leakage. Reported loss: -.
