Kinetic Cybercrime: The Terrifying Shift from Hacking Code to Hacking People

Editor’s Note: A doorbell, a disguise, and a split-second decision to open the door—that’s all it took for an $11 million breach in San Francisco to upend assumptions about the divide between digital security and real-world violence. This article analyzes a high-profile “wrench attack” at a residence owned by tech investor Lachy Groom, illustrating a disturbing trend: criminals are bypassing firewalls not with malware but with duct tape and firearms.

For professionals in cybersecurity, information governance, and eDiscovery, the implications are stark. As digital wealth becomes increasingly tied to personal custody and high-value keys, the threat landscape now includes kinetic risks. Corporate risk management must evolve to account for this hybrid threat—one that is as much about physical proximity as it is about encryption strength.

Kinetic Cybercrime: The Terrifying Shift from Hacking Code to Hacking People

ComplexDiscovery Staff

On a quiet weekend morning in San Francisco’s Mission District, a man dressed as a delivery driver rang the doorbell of a residence on Dorland Street. According to public reports, the pretense masked a carefully orchestrated assault. The suspect used the delivery ruse to gain entry into the home and, once inside, allegedly restrained the occupant and coerced him into transferring cryptocurrency holdings valued at approximately $11 million.

The home is reportedly owned by Lachy Groom, a former early Stripe employee and a well-known figure in Silicon Valley venture circles. However, initial reports indicate that the victim was a resident of the home, not Groom himself. The heist appears to have targeted the victim’s personal digital wallets, and according to several sources, the assailant departed with not only cryptocurrency but also the victim’s phone and laptop—cutting off communication and delaying any immediate recovery efforts.

The Mechanics of a Wrench Attack

This incident exemplifies what security experts have termed a “wrench attack”—a grim reference to the XKCD comic suggesting that a $5 wrench may be more effective than brute-force computing when it comes to obtaining private keys. While exact details remain under investigation, the physical coercion tactic fits a growing pattern: attackers sidestep sophisticated cybersecurity defenses by targeting the human holding the keys.

While comprehensive statistics remain elusive, reports from around the world have surfaced of similar attacks targeting high-net-worth crypto holders. Victims are often selected based on digital “exhaust”—the unintentional breadcrumbs they leave through public wallets, social media, and event attendance. In this case, the suspect appeared to know whom he was targeting, how to gain entry, and what digital assets might be accessible.

A New Layer of Security: Executive Protection and Operational Security

In the crypto era, the boundary between cybersecurity and physical security has collapsed. Investors, entrepreneurs, and executives who self-custody digital assets have become physical targets. Steve Krystek, CEO of executive protection firm PFC Safeguards, notes that visibility is a vulnerability. He frequently emphasizes that when investors flaunt holdings online or speak at crypto events without considering operational security, they are inadvertently advertising their risk profile to potential attackers.

Best practices now include using fresh wallets for each transaction, decoupling identities from cold storage, and implementing physical-layer protections such as secure rooms, surveillance, and duress protocols. In the corporate realm, legal and information governance teams must expand their frameworks to include personal security training and policies for digital key custodians.

Implications for Legal and Corporate Governance Professionals

The San Francisco case underlines a critical vulnerability: when executives control high-value digital assets, the fiduciary and legal responsibilities extend beyond the office. Failure to address the physical risk to key personnel could result in catastrophic loss—not just for the individual, but for the enterprise.

Companies involved in decentralized finance (DeFi), crypto custodianship, and high-value IP management must rethink how they govern access. Information governance teams should include duress wallets, air-gapped hardware key storage, and personal risk minimization strategies within their training. The irreversible nature of blockchain-based theft further complicates recovery and eDiscovery, making prevention paramount.

For eDiscovery professionals, kinetic cybercrime cases present unique challenges. Evidence may span blockchain forensics, doorbell camera footage, cell tower records, and traditional physical evidence. Cross-border complications arise when cryptocurrency is rapidly moved through multiple jurisdictions. The investigative toolkit must expand accordingly. Notably, digital exhaust cuts both ways: the same data trails that allegedly enabled the attacker to identify and target the victim now become critical ESI for investigators—a reminder that the question for corporate counsel is no longer just “How do we protect our data?” but “How does our data expose our people?”

The Unhackable Human

The attackers vanished into the city, leaving behind a stark reality that no amount of code can patch. We have spent decades perfecting the security of the blockchain, only to be reminded that the ultimate vulnerability is flesh and blood. Today’s most sophisticated cyberattack didn’t require a single line of malware—just a delivery uniform and a doorbell.
