Crypto Owners Have Lost $30 Million Through Violent Attacks

Violent attacks targeting cryptocurrency holders stole an estimated $30 million in digital assets during the first half of 2026, putting the year on track to surpass last year’s record as criminals increasingly turned to kidnappings and home invasions, blockchain analytics firm Chainalysis says.

The company estimated that attackers extracted more than $30 million from victims through mid-2026, after a record $58 million was stolen in such attacks in 2025. If the pace continues through the rest of the year, 2026 would become the worst year on record for so-called “wrench attacks,” in which criminals use or threaten physical violence to force victims to surrender cryptocurrency.

“Violent attacks targeting crypto holders, including home invasions, kidnappings, and hostage situations, sometimes called ‘wrench attacks’ in security circles, have surged in recent years,” Chainalysis said. “Criminals have recognized that crypto holders are high-value targets because they possess wealth in an instantly and irreversibly transferrable form.”

Unlike traditional financial assets protected by banks or other institutions, cryptocurrency held in self-custody wallets can often be transferred immediately if owners are coerced into revealing passwords or authorizing transactions.

Chainalysis said documented violent attacks rose to 46 globally through late June, compared with 40 during the same period a year earlier. However, the success rate fell, with only 12 of the 46 attacks resulting in payments, compared with 47 out of 95 in 2025.

The report attributed much of the increase in incidents to France, which has become the world’s biggest hotspot for violent crypto attacks. France recorded 30 publicly known incidents through mid-2026, compared with 19 during all of 2025, according to Chainalysis.

The company linked the surge to the alleged theft and sale of confidential tax records belonging to wealthy cryptocurrency investors. It said dossiers containing names, addresses, phone numbers, holdings and tax information were allegedly stolen by a French tax official in 2024 and sold to criminal intermediaries, giving organized crime groups a ready-made list of potential targets.

French authorities have treated the attacks as organized crime cases, with prosecutors pursuing hundreds of suspects.

The nature of the attacks has also shifted. Home invasions accounted for 37% of documented incidents in 2026, up from 14% in 2025, while kidnappings remained the largest category at 52%.

Family members have increasingly become targets as well. Chainalysis estimated that relatives or acquaintances accounted for roughly one-quarter to one-third of attacks by early 2026, rising to more than 40% in France.

The report said most victims were local residents rather than tourists, suggesting attackers relied on reconnaissance using social media, leaked personal data, blockchain activity or insider information.

Chainalysis identified three broad categories of attackers based on blockchain transaction analysis. Less sophisticated criminals transferred stolen assets directly to centralized cryptocurrency exchanges, making them easier for investigators to trace. More advanced groups used decentralized exchanges, cross-chain bridges and other decentralized finance tools to obscure transactions.

The most sophisticated attackers appeared connected to wider criminal networks. “On-chain analysis of their fund flows reveals connections to numerous illicit actors,” Chainalysis said, citing one case in which stolen funds were routed through an over-the-counter laundering service that had previously interacted with cartel-linked money laundering operations, wallets associated with alleged drug trafficker Ryan Wedding, terrorist financing clusters and Southeast Asian laundering networks.

The company said the findings underscored the need for cryptocurrency holders to avoid publicly disclosing their holdings and to strengthen both digital and physical security. It also urged law enforcement agencies to improve blockchain investigation capabilities, arguing that cryptocurrency transfers leave transaction trails that can help identify organized criminal groups despite the use of physical violence.
