Kidnappings, Home Invasions Highlight Need for Greater Physical Security in Cryptocurrencies
While there is a lot of information online about protecting your digital assets, less is written about the physical threat to cryptocurrency and Bitcoin holders. In recent years, there has been a worrying increase in physical attacks on cryptocurrency holders.
In February, the arrest of five Russian men in Phuket highlights a worrying trend of violent crimes targeting cryptocurrency holders. According to local authorities, the suspects kidnapped a Belarusian couple, forcing them to transfer about 31 million baht ($901,200) in cryptocurrency before releasing them. The incident occurred near the Lor Rong intersection in Muang district, where the couple was taken in a black Hyundai van after being intercepted on their motorcycle.
Initial investigations led to the arrest of four individuals, with two suspects captured at Phuket Airport while attempting to flee the country. The fifth suspect, believed to be the ringleader, was later arrested at a massage parlor in Patong Beach. All five were charged with robbery, coercion and unlawful detention, among other offences.
This month, in Hong Kong, two women were arrested for allegedly kidnapping a three-year-old boy and demanding a ransom of over HK$5 million in cryptocurrency. The boy was rescued unharmed and the suspects were detained for further investigation.
In another high-profile case, a violent gang in the United States was condemned for a series of home invasions targeting cryptocurrency holders. The group’s activities, characterized by extreme violence and coercion, involved numerous victims in multiple states. The gang’s actions included threatening victims with physical violence and demanding access to their cryptocurrency holdings.
Another incident involved a crypto angel investor who was the victim of a home invasion earlier this year. Attackers forced them to unlock a Ledger device. The person, who wishes to remain anonymous due to the ongoing investigation, told CryptoSlate, “I never thought this would be an attack vector for me, but now I know more.”
As cryptocurrencies become more widespread, they are attracting investors and criminals who seek to exploit the anonymity and ease of transfer that these digital assets offer. Law enforcement agencies around the world are responding with increased vigilance, but the decentralized and often pseudonymous nature of crypto transactions continues to pose challenges.
Cryptocurrency security is not just about online security
Cryptocurrency holders are advised to improve their security practices, including using multi-signature wallets, maintaining operational security, and limiting the disclosure of their digital assets. The recent spate of violent incidents serves as a stark reminder of the physical risks associated with digital wealth, prompting a reevaluation of security protocols in the digital age.

“You wouldn’t walk around with hundreds of thousands of dollars in cash on you. Yet many of you do that with your bitcoin. This is a danger not only to yourselves, but to the rest of us, because it’s teaching criminals that wrench attacks on Bitcoiners have a great ROI.”
The $5 Wrench attack refers to a scenario in which an attacker uses physical force or threats (symbolized by a $5 wrench) to coerce a cryptocurrency owner into revealing their private keys or transferring their digital assets. This attack highlights that simple physical intimidation can bypass even the most sophisticated cryptographic security.
While the $5 wrench attack may seem primitive compared to sophisticated hacking techniques, it remains a significant concern in the crypto community. It reminds us that comprehensive security must consider both digital and physical threats.
If you hold significant amounts of Bitcoin or cryptocurrency, we recommend that you be careful about what you share online that relates to your physical location, do not post 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 separate PINs to unlock different wallets. Setting up a honeytrap wallet containing negligible digital assets could allow victims to comply with attackers without giving up the majority of their holdings.
