Physical violence against crypto holders — so-called “wrench attacks” — has already netted criminals more than $30 million in the first six months of 2026, according to a report from blockchain analytics firm Chainalysis released Thursday. That puts the year on track to surpass 2025's record of $58 million in losses from such attacks.
Where the term comes from
The name traces back to an old internet joke about the limits of cryptography: if someone holds a wrench to your head, no encryption can protect your keys. In practice, these are thefts involving physical violence or the threat of it — victims are beaten, kidnapped, or held at gunpoint until they hand over access to their crypto wallets. Chainalysis tracks these incidents through law enforcement reports and on-chain tracing.
The numbers so far
The $30 million figure for H1 2026 is already more than half of last year's total, and the year isn't over. Chainalysis noted that the frequency of attacks has increased, not just the amounts stolen. The firm's report didn't specify which countries or exchanges were most affected, but the data suggests criminals are becoming more brazen as crypto values remain elevated. Small thefts — under $10,000 — make up a growing share of cases, which can make them harder for police to prioritize.
What law enforcement is doing
Chainalysis works with police agencies worldwide to trace stolen funds. The report highlights that many wrench attacks involve relatively small amounts, but the cumulative damage is growing. The firm's analysts said the trend underscores the need for better physical security practices among high-value holders. No specific victims or cases were named in the report.
The report didn't offer a full geographic breakdown, but Chainalysis plans to release a more detailed analysis later this year, including common attack methods and regional hotspots. For now, the question is whether the second half of 2026 will slow down — or accelerate — the pace toward a new record.
