One of the biggest thefts involved a phishing signature attack that drained $1.4 million from a single user. The victim unknowingly approved fake requests, allowing attackers to take control of their wallet. These scams manipulate users into signing digital approvals without fully understanding what they’re authorizing.
In another major case, a user lost $700,000 after falling for an address spoofing tactic known as address poisoning. Here, hackers created a fake wallet address closely resembling one the victim had previously used. Unsuspecting, the user sent funds directly to the attacker’s wallet.

These sophisticated tactics mirror concerns raised in broader crypto discussions, such as the Ethereum simplification efforts aimed at making blockchain interactions safer and more user-friendly.
Hackers Turn to AI and Social Engineering
Crypto phishing scams are evolving quickly. Yu Xian, founder of blockchain security firm SlowMist, revealed that attackers are now targeting users through social media platforms like Telegram. Scammers use AI-generated voice messages and customized chats to trick victims.
In one case, hackers hijacked a Telegram account and sent fake voice clips mimicking a victim’s trusted contact. These voice clips were likely produced using AI tools trained on previous voice recordings.
“Don’t trust just one source. When it involves money, always verify through another reliable channel,” warned Xian.
This method echoes a high-profile case where a U.S. citizen lost 3,520 BTC (worth over $330 million) to a complex social engineering scam, which ZachXBT and other blockchain security teams investigated.

Fortunately, blockchain investigators, including ZachXBT and Binance’s security team, successfully froze around $7 million connected to April’s thefts.
CertiK, another leading blockchain security firm, reported that the broader crypto industry suffered $364 million in total losses from hacks, scams, and exploits during April. Around $18.2 million has since been recovered.
These alarming figures emphasize the increasing sophistication of crypto phishing scams. Experts are now urging the industry to invest in better user education, improved wallet security features, and advanced anti-phishing tools to protect users from ever-evolving threats.
Industry Response and Growing Security Awareness
The rise in phishing scams comes at a time when the crypto sector is seeing both increased adoption and regulatory scrutiny. Major developments, such as the Arizona Bitcoin reserve initiative, highlight how governments and institutions are becoming more involved with crypto assets.
At the same time, the ongoing Bitcoin price surge continues to attract new investors, many of whom may not be fully aware of the sophisticated phishing tactics used by cybercriminals.
Market rumors, such as the recent Ripple Circle buyout, also tend to fuel speculative activity, drawing in fresh capital—and unfortunately, new targets for scammers.
As more people enter the crypto space, security education and robust anti-phishing solutions are more critical than ever. Industry leaders are calling for wallet improvements that can detect suspicious transactions and provide clearer warnings to users before they approve any potentially harmful actions.
