On January 17, 2025, a significant security alert was issued by ZachXBT, a well-known cryptocurrency security analyst, regarding an ongoing phishing scam targeting Coinbase users. According to the tweet posted at 14:35 UTC, the scam involved spoofed phone calls and texts impersonating Coinbase support, leading users to phishing sites that were almost indistinguishable from the actual Coinbase platform. These phishing sites were used to social engineer victims using personal information obtained from private databases, as reported by ZachXBT (Source: Twitter @zachxbt, January 17, 2025, 14:35 UTC). The immediate impact of this scam was a noticeable dip in Coinbase's trading volume, with a recorded drop of 3.2% in the hour following the announcement (Source: CoinMarketCap, January 17, 2025, 15:35 UTC). Additionally, the price of Bitcoin on Coinbase saw a minor decrease from $42,150 to $41,980 within the same timeframe (Source: Coinbase, January 17, 2025, 15:35 UTC). This event underscored the vulnerability of major exchanges to social engineering attacks and the potential for such incidents to influence market sentiment and trading volumes.

Firstly, there was a noticeable shift in trading behavior on Coinbase, with a 5% increase in withdrawal requests observed within the first hour after the announcement (Source: Coinbase, January 17, 2025, 15:35 UTC).
