- Vitalik Buterin proposes secret voice alerts to help crypto users silently call police.
- Rising crypto wrench attacks push experts to warn holders against flaunting wealth.
- Address poisoning scams hit 1.33M wallets, causing over $79M in confirmed losses.
Physical attacks targeting crypto holders are increasing, raising concerns about personal safety. Ethereum co-founder Vitalik Buterin has proposed a secret voice alert system that could help victims silently contact authorities during robberies or kidnappings.
Buterin shared the idea on X. He suggested that users create secret words. These phrases could activate emergency alerts through devices such as watches, phones, or smart home systems.
The system would work quietly. A device could recognize the secret phrase and trigger an emergency response. It could automatically call emergency services and share the user’s real-time location.
Buterin said the feature could deter attackers. He explained that criminals may hesitate if they believe police could arrive quickly. The risk of rapid response could disrupt robbery attempts.
“If we create an environment where if you rob someone, there is at least a 20% chance that the police will be on their way immediately,” Buterin wrote. He said attackers would have less time to take anything.
Crypto Crime Shifts From Online to Physical Threats
Physical threats against crypto holders have grown alongside the value of digital assets. Criminals sometimes target individuals believed to hold large crypto balances. These attacks can involve threats or forced transfers.
One recent case involved David Princay, the head of Binance France. Three masked suspects attempted to enter his home. The attackers mistakenly broke into a neighbor’s house instead.
The suspects fled after the mistake. They took two mobile phones during the incident. Police tracked the stolen devices and later arrested the suspects at Lyon Perrache train station.
Another incident occurred in Le Chesnay, France. Criminals disguised as police officers threatened a couple. The victims were forced to transfer about €900,000, or roughly $1 million, in Bitcoin.
Security experts warn that physical coercion is becoming more common. At the Litecoin Summit 2025, Casa co-founder and CTO Jameson Lopp discussed the issue.
There was a concern over “wrench attacks.” This happens when criminals use threats to obtain private keys from users. He recommended that users of cryptocurrencies should limit their exposure.

“Shut up. Stop flaunting your wealth,” Lopp stated during the event. He recommended that users should not flaunt their assets.
Lopp Warns Crypto Users About Safety Risks
He advised that users should use secure methods when making transactions. When making over-the-counter deals, users should do so in public places. This is because meeting with people can expose them to more danger.
He recommended that users should take security measures at home. He stated that simple security measures can prevent criminals from targeting them. He even stated that a dog can serve as a security system for a person.
Another security concern for users is online threats. One form of online threat is Ethereum address poisoning. This happens when criminals send small amounts of digital currencies with wrong addresses.
The victims may end up using a wrong address for their subsequent transactions. This attack was recorded by researchers at 17.37 million between July 2022 and June 2024.
Approximately 1.33 million wallets were targeted in these attacks. The confirmed losses were more than $79 million.
Coinbase refers to this attack as “zero transfer phishing.” The FBI indicates that a shorter wallet address may result in errors. Experts recommend that users store their private keys offline as a way of preventing many cyberattacks.
As both physical and cyber attacks are on the rise, security measures are becoming more necessary for cryptocurrency holders. Buterin’s voice alert system could be a further measure for personal security.
