Crypto wrench attacks steal more than $30M so far in 2026: Chainalysis

Latest NewsPublishedAug 6, 2026

While only 12 of 46 documented attempts resulted in payment, data leaks and attacks on relatives are widening the physical risks facing crypto holders.

Criminals stole more than $30 million through physical attacks on crypto holders in the first half of this year, putting the year on pace to surpass the record $58 million stolen in 2025.

In a Chainalysis report released Thursday, the blockchain analytics firm stated that 46 violent crypto-related incidents had been documented globally through late June, up from 40 during the same period in 2025. The incidents include kidnappings, home invasions and hostage situations, collectively known as “wrench attacks.” 

The findings suggest wrench attacks are increasing, expanding the risks facing crypto holders beyond custody and asset management to their physical safety, homes and families.

as reported by the report, only 12 of the 46 attempts resulted in payment, giving attackers a 26% success rate, down from 49% in 2025. nevertheless, the report acknowledged that known cases likely understate the scale of the problem, as many attacks go unreported. 

Chainalysis stated the “tradecraft tends to be amateur at the point of violence, but professional at both ends,” with victims often selected through data leaks, social media or insider information before low-skilled crews carry out the attacks.

In July, Interior Minister Laurent Nuñez put the first-half count at 77 kidnappings, extortions or attempted extortions, up from 45 in all of 2025. In response, the government has introduced a rapid-alert and protection system and promised greater intelligence-sharing and coordination with the crypto industry.

Chainalysis stated in the Thursday report that the alleged misuse of French tax records was the likeliest driver of the surge. A French tax official allegedly accessed and sold information about crypto investors to criminals, while a separate breach at crypto tax-reporting company Waltio reportedly exposed data belonging to about 50,000 users.

Onchain activity also showed varying levels of sophistication. Some attackers sent stolen funds directly to centralized exchanges, while others used bridges, decentralized exchanges and laundering services. Chainalysis stated the most advanced cases showed links to broader criminal networks.
