Simply put
- Consider using a multi-sig wallet or methods to introduce a time delay.
- Prepare scripts for potential coercive situations, like saying, “The wallet is with my lawyer and takes 72 hours to access.”
- Keep a decoy wallet on your phone or limit the funds in your hot wallet.
- Protect your assets. It’s wise to avoid sharing details about your holdings or wallet arrangements online.
Back in 2009, the webcomic XKCD introduced a concept in cybersecurity known as the “$5 wrench attack.” It humorously illustrates how simple threats can override complex encryption, where a mere $5 wrench can compel someone to give up their password instead of going through a complicated hacking process.
Unfortunately, this idea is no longer just a joke. Nowadays, more serious assaults occur frequently. Criminals prefer to physically threaten individuals, rather than relying solely on high-tech methods like hacking private keys or stealing seed phrases.
A recent incident in Uganda involved Fest Ivaibi, the founder of Mitropurus Lab, who was reportedly attacked outside his home and forced at gunpoint to transfer codes equating to about $500,000.
In France, the crypto community is facing a wave of terrifying incidents. Earlier this month, a cryptocurrency entrepreneur’s father was lured in Paris and held ransom for between €50,000 and €7 million in cryptocurrency. Fortunately, he was freed after two days, and five suspects were arrested. In another alarming case, a CEO and her pregnant daughter narrowly escaped a daytime abduction attempt, thwarted by bystanders. This was just one of the six reported incidents in the area since January.
In the United States, three teenagers lured a man from Las Vegas into the Mojave Desert last November, where they demanded access to his cryptocurrency before leaving him behind after stealing $4 million in digital assets. Recently, two 16-year-olds from Florida have been arrested and face multiple serious charges.
With Bitcoin reaching unprecedented heights, the stakes are higher than ever. So, how do you protect yourself when the biggest vulnerability might just be you?
New tools, wallet setups, and physical security protocols have emerged that can bolster your defenses against direct threats. Here’s how you might start thinking like a security-conscious individual:
1. Multi-sig wallet
A multi-signature wallet allows multiple private keys to authorize transactions. Typically, a setup may require two out of three keys to move funds. This means if an attacker only manages to obtain one key through coercion, they won’t be able to access your full holdings.
Services like Nunchuk and Casa offer solutions that allow you to distribute keys geographically—keeping one at home, another in a bank, and perhaps the third with a lawyer—making theft significantly more difficult.
However, be cautious: attackers might pressure one of the other key holders for approval.
2. Shamir’s Secret Sharing
Many wallets, including Trezor models, utilize “Shamir’s Secret Sharing,” an algorithm that divides recovery seeds into several parts. You only need a specified number of pieces to recreate the key. This way, you can distribute trust among different people or secure locations.
There are also options like Vault12, which helps you preserve access only when necessary.
Yet, like with multi-sig wallets, this method’s security hinges on the trustworthiness of your co-seed holders.
3. Duress wallet and bait
Some wallets, including Blockstream Jade, offer a “duress PIN”—one code to access your actual wallet and another to wipe it clean. This can serve as a useful tactic in a high-pressure situation.
Bear in mind, if someone is stalking you online, they may suspect that you possess far more than what your decoy wallet displays.
4. Conceal your assets
A good strategy is to avoid appearing as a potential target. Privacy-enhancing tools can cover up your blockchain footprint. Monero, for example, utilizes stealth addresses to mask transactions. Wasabi Wallet implements coin mixing techniques to obscure the trail of your coins.
Still, whether you try to hide your wealth or not, it’s often fairly easy to identify active players in the crypto space.
5. Panic and remote wipe features
Many modern hardware wallets, like Trezor and Ledger, come equipped with features that allow users to quickly disable their wallets using special codes. Some wallets that used to provide extraordinary security have faced issues or law enforcement scrutiny.
However, triggering such a wipe while under duress can be risky. Also, relying on text messages can be problematic if they fall into the wrong hands.
6. Air-gap hardware wallet
Many affluent crypto holders prefer using hardware wallets kept offline. Devices like Cold Card and Keystone Pro can approve transactions without ever connecting to the internet, requiring the attacker to physically acquire the device and its access codes.
That said, highly motivated thieves might still find ways to access your hardware, especially in extreme situations.
7. Wearable panic button with GPS tracking
Compact emergency buttons have been created as personal safety devices. Although initially designed for general emergencies, some models provide alerts along with GPS tracking to designated contacts. They allow users to communicate directly for assistance.
Nonetheless, wearing such a device might signal to potential threats that you’re guarding valuable assets.
