The Alarming Rise of Crypto-Related Violence: How France Became a Hotbed for Wrench Attacks

A disturbing trend is unfolding in France, where crypto holders are being targeted in a surge of violent wrench attacks, prompting concerns over the safety of digital asset owners. The country has witnessed a staggering 41 crypto-related kidnappings this year, occurring at a rate of roughly one every two to three days. This alarming rise has led the government to take notice, with officials acknowledging the severity of the issue at a recent blockchain and crypto conference in Paris. According to Jean-Didier Berger, Minister Delegate to the Interior Ministry, a new set of measures is being developed to tackle the problem, including a prevention platform that has already garnered thousands of registrations. However, authorities concede that more needs to be done to stem the tide of these attacks. The term 'wrench attack' refers to the use of physical force to extract access to digital assets, often proving easier for attackers than attempting to break encryption. Researchers note that the method of identifying victims has shifted from scanning for technical vulnerabilities to building profiles based on social media activity, public appearances, and leaked datasets. This approach allows attackers to track routines and identify points of weakness. The problem is further exacerbated when insiders, such as government officials, inadvertently provide attackers with sensitive information. The pool of potential victims has expanded, with mid-level holders increasingly being targeted, sometimes based on limited or indirect signals. Cases now include families, with children being targeted alongside their crypto-holding parents, making the attacks harder to categorize by severity. Notable cases include the kidnapping of Ledger co-founder David Balland in France, who was rescued after a police operation, and other instances of prolonged captivity and torture. Experts warn that both opportunistic and organized groups are involved, with signs of increasing coordination among attackers. After obtaining funds, attackers tend to move quickly, converting crypto assets into stablecoins and routing them across multiple chains, making recovery more difficult. France's role in this trend may be attributed to a mix of factors, including cases involving leaked personal data and cross-border criminal networks. Rising asset prices have increased the potential payoff from a single attack, while improvements in digital security have reduced the effectiveness of purely technical exploits. The increase in attacks has raised questions about the risks of self-custody, a core principle of cryptocurrency. Security experts recommend measures such as multi-signature setups, withdrawal delays, and spending limits to reduce risk by limiting how much can be accessed under duress.
