The primary scam method used is called Rainbow Drainer, where a fake airdrop is organized to trick victims into verifying transactions and inadvertently granting control of their wallets to the attackers. Leveraging technology to prevent wallets from reflecting the changed balances, hackers managed to steal 2.14 million USD from 2,189 wallets using this method.
Another prevalent scam method is called Node Drainer, where scammers utilize a Christmas campaign for a phishing attack. This form of attack yielded over 2 million USD from 1,700 individuals within a two-week span during the holiday season.
Notably, Scam Sniffer reported that one attacker's wallet stole 1 million USD, and subsequently, they swapped USDC for ETH through AllBridge.
Unlike Ethereum, where most hacks occur due to approval-related issues, on Solana, fraudulent schemes mainly involve deceiving users into making direct transfers. Although Solana supports transaction simulation, hackers are increasingly employing sophisticated tactics to circumvent regulations and make victims more susceptible to traps.
In addition to individual users' wallets, blockchain platforms are also in the crosshairs of hackers, but this requires more complex attack techniques. According to De.Fi's report, the crypto industry witnessed a loss of 1.95 billion USD due to scams, hacks, and security attacks in 2023.
