UK crypto heist: convictions and self-custody risk
A heist of more than 4.3 million in cryptocurrencies in the UK calls into question the security of self-custody and the risks of the human factor.
In June 2024, the cryptocurrency world witnessed an audacious robbery in the UK, where three men embezzled over $4.3 million in digital assets with a disturbing script: disguised as errand boys, they forced entry at gunpoint to extort private keys.
The case ended in November 2024, when Sheffield Crown Court handed down the sentences for Faris Ali and his two accomplices, following the recovery of almost all the loot by the Metropolitan Police.
The Tactic Exploited: Under the Mask of Service
The key to the operation was the tactic of the 'errand boy', which exploits reliance on logistical infrastructure to overcome the biggest hurdle of a home invasion: gaining access.
Telegram chats obtained by investigator blockchain ZachXBT have shown the robbers as they coordinated their approach, sharing photos of the victim's building shortly before the attack. Minutes later, with the victim opening the door expecting a package, the forcible transfer to two Ethereum addresses occurred.
I am proud to share that Faris and his two other accomplices have just been convicted and that almost the entire amount of the stolen funds has been seized by the Metropolitan Police (MET Police)," he said the selfie on X

The Weakest Link: The Human Factor and Data Breach
ZachXBT's investigation traced the attack back to a 'crypto data breach', a data leak that provided criminals with vital information, linking wallet holdings to the victim's physical address.
The attack demonstrates that more sophisticated cryptographic defences - such as multi-sig wallets or cold storage hardware - are ineffective when the attacker can force the victim to sign transactions in real time.
The OpSec Impost and the Future of the Self-Custody
The case fits into a broader pattern of "home invasion" in Western Europe, an attack vector that sees criminals using SIM swaps, phishing, or social engineering to map holdings to physical locations.
The immediate lesson for holders of large assets is the need for 'opsec' (operational security): compartmentalise funds, remove personal information from public databases and treat any unsolicited visits as a potential threat. However, these measures undermine the convenience and transparency that self-custody promises.
The underlying question is whether self-custody can remain the default recommendation for anyone holding significant value. If high net worth concludes that self-custody exposes unacceptable physical risk, migration to insured institutional platforms could see the industry trade off decentralisation for security.
Eleven Drainer, a new phishing-as-a-service, is expanding its business. Despite the sophistication of the attacks, human error remains the main weakness. The defence lies in user discipline.
