In a concerning trend for the crypto community, 2025 is shaping up to be the most dangerous year yet for Bitcoin holders, with a dramatic rise in so-called "wrench attacks" — violent physical assaults aimed at forcing individuals to hand over access to their crypto wallets.

According to recent data compiled from multiple blockchain security reports and law enforcement disclosures, there have already been at least 35 publicly documented wrench attacks in the first seven months of the year — a figure that nearly matches the entirety of 2021, previously the worst year on record with 36 reported cases.

What Are "Wrench Attacks"?

The term "wrench attack" originates from a satirical comic in which an attacker bypasses encryption by threatening the user with a wrench — a metaphor that’s become all too literal. These attacks involve physical coercion — ranging from home invasions and kidnappings to torture and extortion — used to gain access to digital wallets.

In 2025, the rising value of Bitcoin and other cryptocurrencies has made holders lucrative targets, especially as high-profile investors, developers, and company executives become more visible through media exposure and blockchain transparency.

France Emerges as a Hotspot

France has seen some of the most shocking cases this year. In separate incidents, attackers kidnapped and assaulted relatives of key crypto executives, including the daughter of Paymium’s CEO and the family of a Ledger co-founder. In one case, a victim was tortured and disfigured, with the attackers demanding millions in Bitcoin as ransom.

These attacks have prompted French authorities to increase protective measures for prominent figures in the crypto sector, including offering personal security support and emergency response coordination.

Global Reach, Growing Fear

While France stands out for its volume and severity of attacks, wrench attacks in 2025 have also been reported across the U.S., the U.K., Southeast Asia, Australia, and Latin America. Investigators believe this is only the tip of the iceberg — with security experts estimating that only 10% to 30% of such crimes are ever reported publicly due to fear, reputational risk, or lack of legal clarity.

Cybersecurity advocate and Casa co-founder Jameson Lopp recently stated:

“We’re seeing an average of one attack per week, and those are just the ones we know about. The real number is probably two to three times higher.”

Why the Spike in 2025?

Several factors have converged to make 2025 a perfect storm for wrench attacks:

• Bitcoin’s price surge, with BTC trading between $80,000 and $95,000 for much of the year, has increased the incentive for violent theft.

• Leaked data from past hacks and blockchain analytics tools have made it easier to trace high-value wallets to real identities.

• Poor personal security and oversharing on social media continue to expose crypto holders to targeted attacks.

Industry Response

In light of the growing threat, crypto security companies are urging individuals to adopt multisignature wallets, which require approval from multiple parties to execute transactions. Others are exploring multi-party computation (MPC) systems that prevent any single individual from being solely responsible for access to funds.

Meanwhile, security firms and self-custody advocates are warning crypto users to:

• Limit personal exposure online.

• Avoid flaunting wealth or transactions.

• Use decoy wallets and time-locked backups.

• Consider hiring personal security if managing large portfolios.

A Wake-Up Call

The rise in wrench attacks is forcing the crypto industry to confront a long-overlooked reality: financial sovereignty comes with physical risks. As self-custody becomes more mainstream, so too must the infrastructure, awareness, and culture of personal security.

The rest of 2025 will be closely watched. If the current pace continues, experts fear we could see 60–70 wrench attacks before the year ends — setting a grim new benchmark for physical crypto-related crime.
