Wrench Attacks Force Crypto Wallet Unlocks, Bypassing Encryption

Key Takeaways

• “Wrench attacks” involve physical coercion, violence, or threats against individuals to force them into unlocking crypto wallets or authorizing transactions.
• These attacks bypass traditional encryption methods by targeting the human element, rather than exploiting software vulnerabilities.
• The attacks are a global concern, with incidents reported in France, the United States, the United Kingdom, and Canada.
• Victims often include investors, traders, company executives, and their families, with public exposure of crypto wealth increasing risk.
• Mitigation strategies involve enhanced personal security, discretion about holdings, and multi-signature wallets for significant assets.

The landscape of cryptocurrency theft is undergoing a dangerous evolution, shifting from purely digital exploits to methods involving real-world violence. Cybercriminals are increasingly employing physical force, threats, home invasions, and even kidnapping attempts to compel victims to unlock their digital wallets or approve illicit transfers under duduress. This disturbing trend highlights a critical vulnerability in even the most robust encryption: the human element.

These incidents are colloquially termed “wrench attacks,” a phrase that underscores the brutal simplicity of bypassing sophisticated encryption by directly targeting the individual who controls the cryptographic keys. Rather than attempting to crack a wallet’s technical security, assailants focus on coercing the owner into granting access themselves.

Analysts at TRM have identified a growing pattern of such physical assaults against individuals associated with significant digital asset holdings. This includes high-net-worth investors, active traders, cryptocurrency company executives, and even their family members. The increasing public visibility of crypto wealth is directly translating into tangible safety risks for those involved.

Reports of wrench attacks span multiple continents, with incidents documented in France, the United States, the United Kingdom, and Canada. This global phenomenon blurs the traditional lines between cybercrime and conventional violent crime, compelling both victims and security professionals to fundamentally re-evaluate how access to digital assets is safeguarded. As TRM said in a report, criminals are drawn to cryptocurrency due to the speed and irreversible nature of transfers, making it an appealing target for forced extraction.

Wrench Attacks Bypass Encryption

A wrench attack operates entirely independently of typical cyber threats like malware, phishing scams, or software vulnerabilities. The core mechanism involves an attacker using intimidation or direct physical force to make a victim divulge passwords, unlock devices, surrender a hardware wallet, or explicitly authorize a transaction. The term itself is a stark reminder of a long-held security principle: no matter how strong the encryption, it offers no protection if the individual possessing the secret key is physically compromised.

This type of threat stands in sharp contrast to digital compromises, such as the theft of crypto wallet seed phrases through malicious software designed to capture recovery information. In wrench attacks, the physical safety of the victim becomes the critical point of failure, rather than a technical flaw in the digital security infrastructure.

France has emerged as a significant hotspot for these dangerous incidents. In May 2025, masked individuals reportedly attempted to abduct the daughter and grandson of a prominent cryptocurrency CEO in Paris. Fortunately, the attempt was thwarted by the timely intervention of relatives and bystanders. Earlier that same month, the father of another crypto entrepreneur was kidnapped in Paris, with his captors reportedly demanding a ransom ranging from EUR 5 million to EUR 7 million. The victim was successfully rescued after 58 hours, leading to the arrest of five suspects. The TRM report also highlighted the January 2025 kidnapping of Ledger co-founder David Balland and his partner from their home in central France. Attackers demanded EUR 10 million and reportedly inflicted injuries on Balland to coerce compliance before both victims were ultimately rescued.

Similar patterns have been observed in other regions. In the United States, prosecutors have detailed cases where criminal organizations meticulously tracked individuals believed to possess substantial crypto holdings. One such incident in July 2024 involved a home burglary in New Mexico, where a hardware wallet was stolen.

Criminals often combine online reconnaissance with physical targeting. They may compile victim profiles by analyzing social media posts, public discussions about wallet activity, travel itineraries, family details, and any visible displays of wealth. This information is then used to plan and execute a physical assault.

What You Should Do

• Practice Extreme Discretion: Avoid publicly linking your identity to cryptocurrency wallet addresses. Refrain from sharing details about your investment success, travel plans, home specifics, or family information on social media or public forums.
• Implement Multi-Signature Wallets: For substantial cryptocurrency holdings, utilize multi-signature (multisig) wallets. These require multiple approvals (from different devices or individuals) to authorize a transaction, creating a crucial barrier against single-point coercion.
• Enhance Physical Security: Based on your threat assessment, consider implementing advanced home security systems, secure transport arrangements, and protected storage solutions for hardware wallets. Individuals with a high public profile or significant assets may benefit from professional security support.
• Educate Family Members: Ensure family members are aware of the risks and warning signs of potential targeting. Establish protocols for discussing suspicious activity, avoiding confrontation with suspected surveillance, documenting concerns, and promptly notifying law enforcement of any threats.
• Integrate Physical and Digital Security: Recognize that physical and digital security are interconnected. Strong online practices, such as avoiding phishing attacks and using robust authentication, must be complemented by real-world security measures.
