In an unexpected twist, a phishing scammer has returned $9.3 million in DAI to a victim, nearly a year after stealing $24 million. The event has stunned the crypto community and raised questions about the motivations behind the return.
The Phishing Attack
Last September, the victim fell for a sophisticated phishing attack, resulting in the loss of $24.2 million in crypto assets, including 9,579 Lido Staked Ether (stETH) and 4,850 Rocket Pool (rETH) tokens. The scammer exploited the "Increase Allowance" feature of ERC-20 tokens, which allows third parties to spend tokens belonging to the owner. This incident highlighted significant vulnerabilities in token approval processes.
The Return of Funds
The scammer, using the Dai (DAI) stablecoin, returned the funds across two transactions. On July 8, $5.23 million was returned, followed by another $4.04 million on July 13, according to Etherscan data. The funds were transferred through an address labeled as Railgun Relay, an intermediary for the privacy protocol.
Scam Sniffer's Discovery
The return of funds was first noticed by Scam Sniffer on July 13. Scam Sniffer also pointed Cointelegraph to an onchain message from the hacker, who reached out to the victim via a different wallet address on July 6, stating, "Hello, I am the guy who took your money. I want to give the money back."
Market Impact and Analysis
The $9.3 million return represents a 38.4% recovery of the stolen funds at the September 6 prices. However, the value of the 14,429 staked-Ether would have been worth $47.5 million at current prices, reflecting the significant price appreciation of crypto assets.
Implications for Crypto Security
This incident underscores the importance of enhanced security measures in the crypto space. Despite the partial recovery, the initial attack exposed critical flaws in token approval mechanisms. Crypto market data platforms like CoinMarketCap have flagged these vulnerabilities, emphasizing the need for robust safeguards against malicious smart contracts.
Ongoing Threats in the Crypto Space
Phishing scams remain a persistent threat in the crypto industry. In 2023, phishing scammers stole nearly $300 million from 324,000 victims, according to Scam Sniffer’s 2023 Wallet Drainers Report. Notorious phishing groups like Inferno Drainer and MS Drainer have collectively stolen over $140 million, with Pink Drainer alone responsible for over $85 million in thefts before shutting down in May.
The return of $9.3 million in DAI by a phishing scammer is an unprecedented event in the crypto world. While it offers a glimmer of hope for victims, it also serves as a stark reminder of the ongoing security challenges in the digital asset space. As the crypto market continues to evolve, so too must the strategies and technologies designed to protect investors and their assets.
