Rising Crypto Ransom Violence: Protect Yourself from Assault, Home Invasion, and Hostage Threats

The Rise of Physical Threats in the Crypto World

Crypto crime is evolving, and it's no longer just about digital breaches. According to a recent report by blockchain security firm CertiK titled "Skynet Wrench Attacks Report," there has been a troubling increase in attacks that use physical violence, intimidation, or coercion to steal digital assets. These attacks, known as "wrench attacks," force victims to hand over their private keys or passwords.

Between 2024 and 2025, there was a 75% rise in wrench-attack crimes, with a 250% surge in physical assaults. In total, there were 72 cases reported in 2025, but CertiK notes these are only the ones that authorities are aware of. The report suggests that these numbers could be just the tip of the iceberg due to underreporting.

Financial Impact and Regional Trends

Despite the available information, there was a 44% increase in stolen crypto between 2024 and 2025. In dollar terms, victims of these assaults lost approximately $40.9 million last year alone.

While crypto violence is rising globally, Europe remains the most dangerous region, accounting for 40.3% of all wrench attacks. In France, there is now one crypto theft-related kidnapping every two to three days.

CertiK highlighted a particularly gruesome case from France involving David Balland, co-founder of hardware wallet brand Ledger. In January 2025, an organized group of criminals abducted Balland and his wife and tortured them for 48 hours — including cutting off one of Balland's fingers — in an attempt to steal €10 million in crypto. Fortunately, the 10 suspects are now in custody, and Balland and his wife are reportedly safe.

Shift from Digital Hacks to Human Targets

All of these data points led CertiK to conclude that "physical violence is now a core threat vector in the crypto ecosystem."

The shift in criminal tactics is clear. While hacks still occur in crypto, the above statistics show that criminals are now targeting investors and project leaders rather than apps and storage devices. Phil Ariss, who works for the blockchain intelligence company TRM Labs, told CoinDesk that he is "seeing a shift from 'find a wallet' to 'hunt a person.'"

CertiK referred to this as a "technical paradox" in its report. The paradox is that, as encryption standards improve in wallets and exchanges, it becomes more time-consuming and expensive to break into these accounts, leading criminals to turn toward human vulnerabilities like fear and pain.

Another tragic irony is that many of crypto's defining traits make it more desirable for thieves. The FBI notes that, because cryptocurrencies don't have intermediaries, there's no need to fear any friction like a bank flagging suspicious transfers. Plus, crypto transactions are immutable. Once someone sends tokens on a blockchain, that transfer is fixed, and nobody has the authority to reverse it.

With all of these features in place, CertiK doesn't have much hope for a decline in person-focused crypto attacks. In fact, they warn that AI deepfakes will only ramp up these crimes as thieves use lifelike extortion videos or phone calls to prey on victims.

Crypto Security Beyond Cold Storage

In an interview with CoinDesk, Phil Ariss identified "the biggest avoidable mistake" that makes people vulnerable to physical crypto theft. He says it's "tying real-world identity, location, and routine too tightly to visible crypto wealth."

CertiK put it more bluntly in their safety suggestions: "Stop flexing." Anyone holding crypto has to be extra cautious about how much they share online. CertiK strongly recommends keeping details such as your crypto wallets, portfolios, and travel plans off social media and forums.

More criminals are using Open Source Intelligence (OSINT) to identify vulnerable targets, so staying silent is the best way to stay off their radar.

Practical Tips for Protection

Aside from keeping quiet about crypto activities, CertiK suggests creating a decoy wallet. Some wallets let you use an "optional passphrase" to create a second "hidden" wallet with the seed phrase generated during setup. With this strategy, you have plausible deniability because you can give away the legitimate seed phrase while keeping the other wallet a secret.

In general, cold storage devices are best for storing cryptocurrencies because they keep your valuable private keys offline. While this feature prevents hacks, it won't do you much good in a physical assault.

What could help in this extreme scenario is a time buffer, like a preset time-lock setting. Wallets with time locks make crypto unspendable for a few hours or days, even after a criminal initiates a transfer. While this isn't foolproof, it gives you and authorities more time to hopefully catch the attackers and stop the transaction.

CertiK also says to contact authorities immediately if you're receiving unsolicited codes for two-factor authentication (2FA) to your accounts. This is a warning sign that your data has been compromised and that criminals are actively tracking you.

Overall, keeping a low profile and staying vigilant are your best defenses against these gut-wrenching attacks.
