Key Takeaways: Home invasions rose to 20 verified incidents in H1 2026 from just one a year earlier. France accounted for 33 of 52 global wrench attacks, or 63.5% of the total. CertiK recorded $124.1 million in financial exposure, up from $10.5 million in H1 2025.
Home invasions overtook all other tactics in crypto wrench attacks during the first half of 2026, rising to 20 verified incidents from just one a year earlier, as total financial exposure surged 11.8-fold to $124.1 million, according to blockchain security firm CertiK.
CertiK verified 52 physical coercion incidents globally in H1 2026, up 33.3% from 39 in the same period of 2025, the firm said in its Intel3D: H1 2026 Wrench Attacks Report published July 22. Recorded financial exposure reached $124.1 million, compared with $10.5 million a year earlier, with the average loss per incident jumping to $2.39 million from $270,000 — a 785% increase that signals attackers are targeting higher-value victims rather than casting a wider net.
"The most important forecasting variable is not the price of bitcoin alone. It is the visibility of holders," CertiK said in the report. "Bull markets increase perceived wealth, but data exposure determines whether attackers can identify and locate that wealth."
Europe accounted for 39 of the 52 verified incidents, or 75% of the global total, up from 35.9% in H1 2025. France alone recorded 33 incidents — 63.5% of all cases worldwide. French Interior Minister Laurent Nuñez said July 2 that authorities had logged 77 crypto-linked kidnappings, extortion cases or attempted extortion cases during the first half, up from 45 in all of 2025. The gap between CertiK's 33 and Nuñez's 77 reflects methodology: CertiK counts only publicly reported incidents it can independently verify, while French police data includes all cases logged by law enforcement.
The shift from 1 to 20 home invasions represents the single sharpest movement in the data, with the tactic now accounting for roughly 41% of all cases. Kidnappings rose more modestly to 16 from 12, while robberies declined to one from five. CertiK described home invasions as attacking a victim's "entire security perimeter," with access vectors including doorbell impersonation as delivery workers or utility staff, fake business meetings, transit interception at airports, and proxy targeting of family members and employees.
CertiK attributed France's disproportionate share to the country's visible crypto ecosystem combined with two major identity-data exposures: the France Travail breach that drew a €5 million fine from France's data protection authority, and an ANTS portal breach affecting up to 19 million citizens. These breaches connected identities and home addresses with perceived crypto wealth, creating what the report described as valuable targeting records.
The report identified a tension between compliance infrastructure and physical security. DAC8, which took effect Jan. 1, 2026, obliges EU crypto-asset service providers to report and automatically exchange crypto transaction information between tax authorities. CertiK warned that such exchanges "creates valuable targeting records" and demanded strong access logging, insider monitoring and breach notification. The concern is not hypothetical: the report documented a French tax administration employee who allegedly sold confidential cryptocurrency investor data to criminal networks.
In response, French authorities launched a dedicated prevention platform and a rapid-alert system for crypto holders and professionals. Nuñez said emergency measures have resulted in approximately 200 arrests, with several dozen identified as minors.
CertiK said the rise in physical coercion challenges conventional self-custody advice, which assumes the adversary attacks the system rather than the person holding it. The firm recommended multisignature or multiparty computation arrangements that remove any single person's unilateral authority, withdrawal time locks, spending caps, allowlists, and geographically separated signing devices so one threatened individual cannot immediately release all available assets.
Notable cases in the period include a couple near Paris forced to transfer roughly €900,000 in bitcoin during a March 2026 home invasion, and the pseudonymous UK holder Sillytuna who surrendered approximately $24 million in aEthUSDC on March 4, with proceeds allegedly laundered across multiple chains before conversion to Monero.
CertiK's report projects that if the $2.39 million average loss holds while incident growth stays near 33%, full-year exposure would clear $240 million without any acceleration in frequency. The firm also flagged proxy targeting — attackers going after family members, employees or assistants rather than holders directly — as the likely dominant vector by H1 2027, because proxies are easier to approach and create stronger emotional leverage.
