.. My entire meta mask wallet was drained once I connected my meta mask to a fake airdrop website. It took 30 seconds to wipe out my entire wallet. It was too late when I revoked the connection. These are known as crypto wallet drainers. However, I see many new media and blog articles refer to it as malware.
Yeah, it should be malicious smart contract or just malicious website. Malware has a different meaning. Regardless the name it will still steal your funds if not carefully secured your device. Btw Sorry for the loss.
