A victim has lost over $2 million worth of Tether’s stablecoin ($USDT) in a targeted address poisoning scam involving zero-value transfers.
The incident underscores the increasing complexity of crypto-related scams, with over 18 major attacks recorded in April alone.
According to a report by Web3 security firm Cyvers, the victim was scammed twice within a three-hour period, losing a total of $2.6 million in USDT.
The victim was targeted with an address poisoning scam, a tactic where attackers send zero-value transactions from a wallet address that closely resembles a legitimate one the victim uses or interacts with.
The goal is to trick the victim into accidentally copying and pasting the scammer’s wallet address when making a future transaction.
In this case, the victim first sent $843,000 in USDT to the scammer.
Just three hours later, they mistakenly transferred an additional $1.7 million in USDT to the same fraudulent address.
“We are continuously monitoring such scammers and working to prevent these incidents in real time,” Cyvers stated.
This incident follows a recent warning from Ripple, urging users to stay alert for scams, which often increase during crypto market rallies.
In a blog post, the blockchain company pointed out the growing number of scams involving AI-generated content, including deepfake videos of Ripple CEO Brad Garlinghouse “giving away XRP.”
“These posts include branding and profile pictures that look exactly like what the companies, individuals or government authorities use,” Ripple wrote.
“It’s important to be able to spot which accounts are fake, and which posts are cryptocurrency giveaway scams.”
2025 has been challenging for the crypto industry, with an unsettling number of scams across the sector.
In April alone, 18 major hacks were reported. The most severe involved a fake Bitcoin (BTC) transaction resulting in a loss of $330.7 million.
In February, Dubai-based exchange Bybit suffered a $1.46 billion loss after hackers deployed malware to trick the platform into approving unauthorized transactions.

This theft has been labeled the largest heist in history, surpassing the previous crypto record of $611 million stolen from Poly Network in 2021, most of which was later returned.
It also exceeded Saddam Hussein’s $1 billion looting of Iraq’s Central Bank in 2003.
