Attacks on crypto holders now average $2.4M each — nine times more than a year ago

Attacks on cryptocurrency holders are getting more violent. According to blockchain security firm CertiK, 52 verified physical attacks on crypto investors were recorded worldwide in the first half of 2026 — up 33% from the same period a year earlier.

The Numbers for H1 2026

• Verified incidents — 52, versus 39 a year earlier (+33%)
• Total losses — $124.1 million, versus $10.5 million in H1 2025 (nearly a 12x increase)
• Average loss per incident — about $2.4 million, versus roughly $270,000 a year earlier (nearly a 9x increase)
• Europe's share — 75% of all incidents (39 of 52), with France alone accounting for 33 cases (63.5% of the global total)
• Home invasions — 20 cases in H1 2026, up from just 1 in H1 2025, now the most common attack method

How Criminals Find Their Victims

Data leaks and oversharing on social media have made it noticeably easier for criminal groups to find potential targets. According to researchers, attackers spend weeks or months building detailed profiles of prospective victims using leaked databases, tax records, exchange data, on-chain activity, conference attendance, and social media posts.

“H1 2026 confirms that wrench attacks are no longer a fringe phenomenon or an edge-case risk for cryptocurrency holders.”

Specific Cases

Documented incidents include a forced transfer of roughly €900,000 in bitcoin during a home invasion near Paris, and the UK's "Sillytuna case," where a victim was coerced into transferring about $24 million in stablecoins; the stolen funds were then laundered across multiple chains and converted into Monero.

What This Means for Crypto Holders

The defining feature of a wrench attack is that it bypasses technical security entirely: it doesn't matter whether coins sit in a cold wallet or are protected by an elaborate seed phrase — neither one stops physical coercion. That's exactly why security experts increasingly focus their advice not on how to hide your keys better, but on how to avoid revealing that you hold a large crypto balance in the first place: don't broadcast gains on social media, avoid publicly linking your name to wallets with a visible balance, and treat your personal information with the same seriousness as the keys themselves.

Nothing here should be taken as financial advice — just information to consider.
