Bitcoin miner MARA spent $4.3 million on CEO Fred Thiel's personal security in 2025, including vehicle armoring, as a surge in crypto wrench attacks forced companies to rethink executive safety. The figure, disclosed in a recent report, underscores a growing cost of doing business in an industry where digital wealth can lead to physical danger.
Armored SUVs and tighter protocols
The spending covered more than just guards. MARA paid for armored vehicles to transport Thiel, a common precaution for executives at risk of kidnapping or robbery. Crypto wrench attacks — where attackers physically threaten or harm victims to steal private keys or crypto — have become a global concern, with incidents reported from Southeast Asia to Europe. The company didn't detail how many security personnel were added or whether Thiel now travels with a full detail.
Why the threat is rising
Wrench attacks target anyone perceived to hold significant crypto. Executives at public companies like MARA, which mines Bitcoin on an industrial scale, are obvious targets. The company attributed the $4.3 million spending directly to this trend. No specific incident involving Thiel has been reported, but the precautionary spending reflects a broader industry anxiety.
A $4.3 million line item
For a company that mined thousands of Bitcoin last year, $4.3 million is a rounding error — but it's a symbolic number. It's the cost of ensuring the person in charge isn't abducted on his way to work. Other crypto firms have quietly boosted security budgets, but MARA's disclosure is one of the most specific to date. The timing isn't great: wrench attacks are becoming more brazen, and executives are adapting.
MARA hasn't said whether 2026 security spending will match last year's level. But with attacks continuing to make headlines, the answer is likely yes — and other CEOs may find themselves riding in armored cars too. For now, Thiel's security detail remains on the clock.
