A sophisticated cryptocurrency theft has shaken the tech community in San Francisco, after armed robbers posing as delivery workers made off with $11 million in digital assets from a residence connected to prominent tech investor Lachy Groom, who once dated OpenAI CEO Sam Altman.
The brazen attack happened last Saturday evening at a $4.4 million property on Dorland Street, where Groom and his fellow tech investor Joshua reside. What looked like a normal package delivery quickly turned into an approximately 90-minute violent ordeal that left one victim physically assaulted and his cryptocurrency accounts completely drained.
The chilling moment an attack started was captured in doorbell camera footage shared on social media. A suspect, convincingly dressed as a courier delivery worker and carrying a white box, rang the buzzer, claiming to represent an affiliate company for UPS.
Organized Network Uses ‘Delivery Scam’ to Rob Resident of $11M in Bitcoin and Ethereum
When asked who he was looking for, the man requested “Joshua” specifically, adding some credibility to what seemed to be a legitimate delivery.
The resident, who identified himself as Joshua, agreed to accept the package. The suspect asked for a signature, then patted his pockets and asked to borrow a pen-a classic social engineering technique that reduced the victim’s vigilance. A few moments later, the attacker followed the resident inside and a loud bang was heard throughout the home.
Things quickly took a turn for the worse once inside. The intruder pulled a gun and threatened to force the victim’s compliance by binding him with duct tape. What transpired next was an enormously elaborate operation that reflected substantial preparations and inside information.
The attacker had a phone on speaker during the attack, with foreign voices feeding him private information about the victim.
This disturbing detail shows that the robbery most likely was orchestrated by an organized criminal network with access to private data regarding cryptocurrency holdings and personal details of the target.
The victim was subjected to physical abuse throughout the ordeal. The attacker had systematically accessed and emptied his cryptocurrency wallets, containing substantial amounts of Bitcoin and Ethereum, while pouring liquid over him.
The suspect disappeared with $11 million in digital currency when police officers arrived at 6:45 p.m., along with the mobile phone and laptop belonging to the victim.
Targeted Crypto Heist in San Francisco Exposes New Frontier of Sophisticated Crime
The responding officers found the victim with visible bruising, yet he had survived the terrifying encounter. San Francisco police have classified this as a targeted attack rather than a random crime, given the particular knowledge about the victim’s cryptocurrency holdings the perpetrators possessed.
The property itself has some interesting connections to the elite of the tech world: public records show that Groom bought the residence in 2021 for $1.8 million from Jack Altman, brother of OpenAI CEO Sam Altman, and it has appreciated in value to $4.4 million since then, reflective of San Francisco’s booming real estate market in affluent neighborhoods.
The incident reflects a growing concern in technology-heavy cities such as San Francisco, where holders of cryptocurrency are increasingly targets of sophisticated criminal operations. Unlike the old bank robberies, thefts of cryptocurrency can be particularly lucrative because transactions are irreversible and difficult to trace once digital assets are moved through various wallets and exchanges.
But law enforcement experts say there is a more sophisticated approach by criminals in identifying and targeting individuals with substantial cryptocurrency holdings. The social engineering-disguising oneself as delivery personnel-along with physical violence and real-time intelligence from accomplices, forms another evolution in crypto-related crime.
SF Crypto Attack Sparks Operational Security Warnings
The investigation remains active as police in San Francisco continue to pursue the identification and arrest of suspects. To date, no arrests have been made.
According to the New York Post, efforts to reach Groom for comment were unsuccessful, which is certainly understandable in light of the trauma endured and ongoing security issues.
This case forcefully reminds one of operational security that is expected to be in place for cryptocurrency investors. Experts suggest keeping large holdings in cold storage, keeping crypto ownership private, and having sophisticated home security features, including surveillance systems, and not accepting any delivery without proper prior protocols.
As the technology community comes to terms with the shocking crime, some question how the attackers could know their target so well and if other attacks could follow in San Francisco’s cryptocurrency-rich neighborhoods.
