Wrench attacks surge in 2025: 52 incidents globally; learn how victims are targeted and key steps to protect crypto assets — read COINOTAG’s security brief.
What are wrench attacks and why are they increasing?
Wrench attacks are violent robberies where perpetrators physically coerce cryptocurrency holders to surrender private keys, seed phrases, or devices. These attacks rose in 2025, driven by high on-chain values, traceable transfers, and criminals’ growing awareness of stored private keys and hardware wallets.
How did the Herzliya home invasion unfold?
A crypto trader in Herzliya was ambushed in his building stairwell on September 7. Three suspects forced him into his apartment, bound him with cables, beat him, and stabbed him in the legs before extracting wallet access.
Prosecutors say the thieves transferred $547,260 in Bitcoin and $42,248 in USDT, and stole a $50,000 Rolex, a laptop, a Trezor hardware wallet, €5,000 and local currency. Investigators arrested an alleged organizer on September 10 using recorded calls, voice analysis, and surveillance footage.
Why are criminals targeting crypto holders now?
High on-chain values and easy peer-to-peer transfers make cryptocurrencies attractive for criminals. Publicly visible wealth or social signals can identify targets. Security researchers, including Jameson Lopp, track these incidents and warned 2025 would likely set new records.
What evidence helped prosecutors in the Herzliya case?
Investigators used recorded calls, voice analysis, and building security cameras to link suspects to the attack. Prosecutors allege the organizer had prior convictions and targeted the trader after learning of his Bitcoin holdings.
