An $11 million crypto theft aimed at venture capitalist Lachy Groom, who previously worked with OpenAI CEO Sam Altman, has brought attention to a disturbing increase in physical assaults on cryptocurrency owners. The event took place in San Francisco’s Mission District, where an armed assailant disguised as a delivery person threatened Groom’s roommate, Joshua, using a firearm, duct tape, and intimidation,
ultimately emptying Ethereum and Bitcoin wallets during a 90-minute ordeal
. The crime,
which investigators called a "deliberate, coordinated criminal extraction"
, sheds light on the increasing risks faced by wealthy individuals involved in cryptocurrency.
This method mirrors a worldwide uptick in so-called "wrench attacks," where criminals resort to violence to seize digital assets. In 2025 alone,
more than 60 such cases have been reported
, including 10 crypto-related abductions in France and aggressive home break-ins in Israel and the UAE. Specialists caution that the anonymous and irreversible nature of blockchain transactions makes these offenses especially attractive to criminals. "
Self-custody works well until someone arrives at your home with a counterfeit UPS badge and a handgun
," commented security expert Mario Nawfal, stressing the importance of secure vault storage and personal protection.
Joshua, the victim, suffered minor wounds during the attack, which involved being tied up, assaulted, and coerced into giving up wallet access. The perpetrator fled with Joshua’s phone, laptop, and $11 million in digital assets and has not been apprehended.
Law enforcement officials believe the incident is part of a larger organized operation
, but no suspects have been detained. Groom, a well-known investor and former associate of Altman, has yet to make a public statement. His connection to Altman,
including a real estate transaction with Altman’s brother in 2021
, has attracted media scrutiny.
This high-profile theft has reignited discussions about crypto safety amid escalating physical dangers. Phil Ariss from TRM Labs pointed out that attackers are increasingly identifying targets through social media,
taking advantage of visible displays of affluence and easily found personal information
.
Meanwhile, industry figures such as Garry Tan of Y Combinator have urged for enhanced protections,
recommending institutional-level storage options like Coinbase vaults
.
Globally, wrench attacks are on the rise due to the difficulty of recovering stolen digital currencies. In France, armed criminals have targeted Ledger hardware wallets, while in Israel, a resident of Tel Aviv lost $600,000 in
Bitcoin
after a violent home robbery
as reported by local media
. This pattern has led to calls for tighter privacy controls and the use of multi-signature wallets to reduce exposure.
As these dangers mount, both regulatory and technological solutions are being explored.
Spain’s Sumar party recently introduced
a proposal for a 47% tax on crypto gains and a "risk traffic light" system for investment platforms. At the same time, established banks such as Standard Chartered are moving into crypto asset custody,
indicating a trend toward more robust, institutional security
.
As the sector adapts to these new threats, evaluating the effectiveness of different crypto protection strategies becomes crucial. The San Francisco robbery is a stark example of how digital fortunes can translate into real-world risks. With digital assets increasingly targeted by organized crime, the industry stands at a pivotal point in balancing progress with protection.
