The frequency of kidnap-and-ransom attempts targeting prominent cryptocurrency executives has surged in recent years. Often called “$5 wrench attacks” in crypto circles, these attempts to extract millions have prompted governments and the private sector to step up protections.
Policymakers in France are developing safeguards, including a prevention platform announced at Paris Blockchain Week, while insurers are offering bespoke kidnap-and-ransom (K&R) coverage that includes awareness and prevention training. As attacks rise, wealthy crypto holders and executives are adopting new personal security measures.
Why crypto execs are targets
Ransoming wealthy crypto holders is not new. A Github repository maintained by early Bitcoin adopter Jameson Lopp has recorded at least 316 physical attacks since 2014. Different attack vectors — impersonation, home invasion, kidnapping — were already topics of public talks by practitioners like Rigel Walsh in 2019.
Lopp’s data shows 79 ransom attacks in 2025, and media have reported 27 attacks on crypto holders so far in 2026. While such crimes affect other wealthy individuals, several features of the crypto world increase vulnerability:
– Rapid wealth accumulation: Some individuals go “from zero to hundreds of billions of net worth in weeks or months,” leaving many without established personal risk infrastructure.
– Openness and sociability: The industry’s informal culture — executives from competing firms socializing together — can reduce privacy and increase exposure.
– Liquidity of crypto: Despite sanctions and monitoring, stolen crypto can still be laundered and cashed out through the right channels, making it an attractive target for criminals, including state-linked hacking groups.
Geography and legal factors also matter. France — and Paris in particular — has become a hotspot for ransom attacks, eclipsing other regions, according to security professionals. High-profile incidents include the 2025 kidnapping and ransom of Ledger co-founder David Balland. Some local laws, such as public entrepreneur registries listing names and addresses, have been cited as exacerbating the risk. Paris’s status as a global attraction concentrates visiting wealth and raises exposure for high-net-worth visitors.
Rising security spending and measures
Crypto executives have significantly increased spending on personal security. In 2024, Coinbase reportedly spent $6.2 million on executive protection for CEO Brian Armstrong — more than the combined security costs of executives at several major financial and tech firms. Ledger co-founder Eric Larchevêque has said he pays over $50,000 a month for security for himself and his family, has installed cameras and weapons at home, and has lobbied for executives to be allowed to carry firearms.
At Paris Blockchain Week, French authorities announced a prevention platform intended to improve coordination; thousands have already signed up. Police presence at the conference was notable, and some attendees received police escorts through the city.
Insurers and brokers respond
Insurance brokers and specialists have seen a surge in demand for K&R and related coverage. Brokers report that conversations about kidnap and ransom have gone from rare to ubiquitous among crypto clients. Companies like Relm Insurance and specialist brokers in the U.K. say clients are requesting K&R policies that combine financial protection with security expertise.
These products typically include:
– Remuneration of funds if a ransom must be paid.
– Access to security specialists and crisis consultants.
– Training and education focused on avoidance: what to say or not say, how to engage, and practical routes and behaviors to reduce risk.
Insurers emphasize prevention: the policies start with training to keep clients out of risky situations — for example, avoiding unlit shortcuts or being cautious about what is shared publicly.
The new reality
The combination of rapid wealth creation, industry openness, geographic concentration of wealthy visitors, and the ongoing ability of criminals to monetize stolen crypto has forced the sector to change rapidly. Executives are investing heavily in personal security, governments are rolling out prevention platforms and increased policing, and insurers are developing tailored K&R offerings that blend financial protection with education and operational support.
