Kidnappings and home invasion incidents highlight the need for improved physical security in cryptocurrencies.
There is a lot of information online about how to protect your digital assets, but less written about the physical threats to cryptocurrency and Bitcoin holders. There has been a worrying increase in physical attacks on cryptocurrency holders over the past few years.
The arrest of five Russian nationals in Phuket in February highlights a worrying trend of violent crime targeting cryptocurrency holders. According to local authorities, the suspects kidnapped a Belarusian couple and forced them to transfer about 31 million baht ($901,200) worth of cryptocurrency before releasing them. The incident occurred near the Lorong intersection in Muang District, where the couple were taken away on a motorbike and taken away in a black Hyundai van.
Initial investigations have led to the detention of four people, with two suspects arrested at Phuket Airport while trying to flee the country. A fifth suspect, believed to be the ringleader, was later arrested at a massage parlour on Patong Beach. All five are charged with robbery, coercion and unlawful detention.
This month, two women were arrested in Hong Kong for kidnapping a three-year-old boy and demanding a cryptocurrency ransom of more than HK$5 million. The child was rescued safely, and the suspects were detained for further investigation.
In another notable case, a violent gang in the United States has been convicted of a series of home invasions targeting cryptocurrency holders. The group’s activities, characterized by extreme violence and coercion, involved multiple victims across multiple states. The gang’s actions included threatening victims with physical harm and demanding access to their cryptocurrency holdings.
Another incident involved a cryptocurrency angel investor whose home was broken into earlier this year. The attackers forced them to unlock their Ledger device. The person, who wishes to remain anonymous due to the ongoing investigation, said: CryptoSlate“I never thought this would be an attack vector for me, but now I know it wasn’t.”
As cryptocurrencies become more mainstream, investors and criminals are increasingly looking to exploit the anonymity and ease of transfer inherent in these digital assets. Law enforcement agencies around the world are becoming more vigilant and responsive, but the decentralized and often pseudonymous nature of cryptocurrency trading continues to pose challenges.
Staying safe in cryptocurrency isn’t just about online security.
Cryptocurrency holders are advised to strengthen their security practices, including using multi-signature wallets, maintaining operational security, and limiting disclosure of digital asset holdings. Recent violent incidents have served as a stark reminder of the physical risks associated with digital wealth, prompting a reevaluation of security protocols in the digital age.

“You’re not going to be carrying hundreds of thousands of dollars in cash, and yet so many of you are doing that with Bitcoin. That’s dangerous. As well as Not only for yourself, but also for the rest of us, you are teaching criminals that wrench attacks on Bitcoiners can yield huge ROI.”
A $5 wrench attack is a scenario where an attacker uses physical force or threats (symbolized by a cheap $5 wrench) to force cryptocurrency owners to reveal their private keys or transfer their digital assets. This attack highlights that even the most sophisticated cryptographic security can be bypassed with a simple physical threat.
The $5 wrench attack may seem primitive compared to sophisticated hacking techniques, but it is still a significant concern in the cryptocurrency community, reminding us that comprehensive security must consider both digital and physical threats.
If you own a significant amount of bitcoin or cryptocurrency, be careful about what you share online about your physical location, avoid posting real-time updates or photos that identify your location, and avoid wearing industry-related clothing outside of conferences. Additionally, many hardware wallets allow users to use a separate PIN to unlock other wallets. Setting up a honeytrap wallet with a small amount of digital assets can allow victims to acquiesce to an attacker without giving up most of their holdings.
