Physical assaults targeting cryptocurrency holders, known as wrench attacks, are increasing in frequency and severity, according to new analysis.
Investor Haseeb Qureshi reviewed data compiled by security advocate Jameson Lopp tracking reported wrench attack incidents.
The dataset showed a steady rise in total attacks over time alongside a shift towards more violent outcomes.
Incidents were categorised into five severity levels, with recent years showing a higher average level of violence.
Western Europe and parts of the Asia-Pacific region recorded the sharpest growth in reported attacks.
North America remained comparatively safer, though the absolute number of incidents also increased.
Analysis showed attack frequency closely tracking overall crypto market capitalisation.
Roughly 45% of the variation in attacks could be explained by market value growth alone.
Higher crypto prices were found to attract increased criminal activity targeting holders.
When adjusted for user growth, data suggested crypto ownership was riskier in earlier years than today.
Qureshi stressed the importance of personal security for high-risk individuals holding digital assets.
This is more than just an intellectual exercise, remember there’s a lot you can do to invest in your own personal security.
Haseeb Qureshi said.
Separate data showed wallet drainer phishing losses declined sharply in 2025 despite ongoing risks.
Losses linked to phishing fell to $83.85 million last year as victim numbers also dropped significantly.
