Coinbase users lose $46 million in two weeks
As cryptocurrency prices climb, so too does scam activity, with Coinbase users reportedly losing over $46 million in suspected phishing scams over the past two weeks.
Blockchain investigator ZachXBT raised the alarm on March 28, revealing a string of high-value thefts, including a single incident involving 400 Bitcoin (BTC)—worth approximately $34.9 million—from one Coinbase-linked wallet, reports Cointelegraph.
Sophisticated Phishing Tactics on the Rise
According to ZachXBT, scammers are deploying increasingly sophisticated tactics such as address poisoning and wallet spoofing, in which victims are tricked into sending crypto to fraudulent addresses that closely resemble legitimate ones.
“It is suspected a Coinbase user was scammed yesterday for 400.099 BTC,” ZachXBT wrote in a Telegram post, adding that the total stolen from Coinbase-linked wallets in March has now exceeded $46 million.
The scams follow a troubling pattern observed across the industry, where fraudsters impersonate major brands or platforms to deceive users into handing over credentials or transferring funds.
Coinbase Responds: “Do Not Share Private Information”
In response to the allegations, Jaclyn Sales, director of communications at Coinbase, confirmed that the company is investigating the reported thefts. She reiterated Coinbase’s stance on user security:
“Coinbase will never call you or ask for your login credentials, API key or two-factor authentication codes. We will also never ask you to transfer funds.”
Sales warned users not to respond to anyone claiming to represent Coinbase who requests such information.
Coinbase Among the Most Impersonated Brands
Scammers have long targeted the Coinbase brand, leveraging its reputation to gain the trust of unsuspecting users. In June 2024, Cointelegraph reported that Coinbase was the most impersonated crypto brand, though tech giant Meta faced over 25 times as many impersonation attempts overall.
As the third-largest centralized crypto exchange, with over $1.6 billion in daily trading volume, Coinbase remains a high-profile target for bad actors seeking to exploit inexperienced or off-guard investors.
How Users Can Protect Themselves
In a recent security advisory, Coinbase urged users to take several steps to safeguard their funds: • Use a dedicated email account for crypto activities. • Enable two-factor authentication (2FA). • Set up an address allowlist to limit withdrawals to pre-approved addresses. • Utilize Coinbase Vault for added protection of long-term holdings.
As phishing schemes grow more sophisticated and widespread, crypto users—especially those on high-traffic platforms like Coinbase—are reminded to stay vigilant and treat unsolicited communications with extreme caution.
