The Basics
If you own cryptocurrency, your phone might be the weakest link in your security chain. On April 15, 2024, Trust Wallet — one of the world’s most popular crypto wallets with over 60 million users — issued an urgent warning to all Apple device owners: disable iMessage immediately. The reason? A zero-click exploit reportedly being sold on the dark web for $2 million that can take over your iPhone without you ever tapping a single button.
With Bitcoin trading at around $63,426 and Ethereum at $3,101 as of mid-April 2024, the amounts at stake for everyday crypto users are substantial. Even a modest portfolio of a few coins could represent thousands of dollars — money that could vanish in seconds if your device is compromised.
Understanding how to protect yourself does not require technical expertise. This guide walks you through the essential steps every crypto holder should take to secure their assets against modern threats.
Why It Matters
Zero-click exploits represent a new generation of attacks that bypass traditional security advice. For years, the crypto community has emphasized the importance of “never clicking suspicious links.” But zero-click attacks do not require any user interaction at all. The exploit is triggered simply by receiving a message — you do not need to open it, read it, or tap anything.
The Trust Wallet advisory specifically mentioned that the iMessage vulnerability targets iOS devices and that high-value crypto holders are the primary targets. However, the underlying principle applies to everyone: if your device is compromised, your crypto wallets, exchange logins, and two-factor authentication apps could all be exposed.
This is not a theoretical risk. The Grand Base protocol on Base also suffered a $2 million exploit on the same day because a developer’s personal computer was hacked, giving the attacker access to private keys. Security threats are real, frequent, and increasingly sophisticated.
Getting Started Guide
Step 1: Disable iMessage on your iPhone immediately if you hold significant crypto assets. Open Settings, tap Messages, and toggle iMessage off. This single action eliminates the attack vector identified by Trust Wallet.
Step 2: Enable Apple’s Lockdown Mode. Available on iPhones running iOS 16 or later, Lockdown Mode significantly reduces your device’s attack surface by disabling many automatic processing features, including complex message attachments. Find it in Settings, then Privacy and Security, then Lockdown Mode.
Step 3: Move your significant crypto holdings to a hardware wallet. Devices like Ledger Nano or Trezor store your private keys on a dedicated device that never directly connects to the internet. Even if your phone is completely compromised, a hardware wallet keeps your private keys safe. Prices start around $60-80 — a small investment to protect potentially thousands of dollars in assets.
Step 4: Switch from SMS-based two-factor authentication to a hardware security key or authenticator app. SMS 2FA is vulnerable to SIM-swapping attacks, where an attacker convinces your mobile carrier to transfer your phone number to their device. Google Authenticator, Authy, or a YubiKey provide much stronger protection.
Step 5: Keep your operating system updated. Both Apple and Google regularly release security patches that address newly discovered vulnerabilities. Installing updates promptly is one of the simplest and most effective security measures available.
Common Pitfalls
Many newcomers to crypto make avoidable security mistakes. Storing your seed phrase digitally — in a note-taking app, email draft, or cloud storage — is extremely dangerous. If any of these services are compromised, your wallet is effectively drained. Write your seed phrase on paper and store it in a secure physical location.
Another common mistake is using the same password across multiple exchanges and services. If one service suffers a data breach, attackers will try the same credentials on every major exchange. Use a password manager to generate and store unique passwords for each service.
Do not ignore security advisories from wallet providers. When Trust Wallet or your exchange sends a security alert, act on it immediately rather than assuming it does not apply to you.
Next Steps
Once you have implemented the basics, consider advancing your security posture further. Research multi-signature wallets, which require multiple devices or people to approve transactions. Explore dedicated crypto security courses offered by platforms like Coursera or the Blockchain Council.
Most importantly, make security a habit, not a one-time setup. Review your security practices monthly, rotate sensitive passwords quarterly, and stay informed about emerging threats by following blockchain security firms like PeckShield and CertiK on social media.
The crypto ecosystem rewards those who take security seriously. A few hours of setup today can prevent devastating losses tomorrow.

This should be pinned on every crypto exchange and wallet app. Most people have no idea what zero-click even means or how exposed they are.
agreed but lets be real, 99% of users wont do any of this until they get rekt personally. convenience always wins over security
Danilo P. saying 99% wont do it is the saddest true thing in this thread. people will lose everything before they spend 12 minutes on a hardware wallet setup
Danilo P. 99 percent wont do it until they get rekt. i watched my buddy lose 12 ETH from a simulated click he never saw. convenience is the enemy of security
theres a reason exchanges default to email 2fa instead of hardware keys. friction kills adoption and they know it
literally watched someone skip setting up a hardware wallet because the setup video was 12 minutes long. lost $4k two weeks later
Will T. 12 minute setup video vs 4k lost. the convenience tax on crypto security is brutal and most people only learn after paying it
Danilo P. convenience always wins until you lose everything. then suddenly a 12 minute hardware wallet setup doesnt seem so bad
Ingrid Kowalski 99% of people dont know what zero-click means and thats the problem. they think not clicking links makes them safe
2M for an iOS zero click on the dark web. nation states pay 10x that. your crypto wallet on a phone with iMessage is a sitting duck
hardware wallet + disabled imessage + separate device for crypto. its annoying but beats losing everything to a $2m dark web exploit
separate device for crypto is the move but most people are not buying a second phone for their $200 bag. hardware wallet is enough for most
trust wallet telling 60M users to disable iMessage was the loudest alarm bell. apple still hasnt properly addressed zero click vectors
turning off iMessage feels extreme until you realize the exploit requires zero interaction. no link no attachment no nothing. just receiving a message is enough
$2M for an iOS zero click. imagine what nation states pay for the same exploits. trust wallet was right to sound the alarm
nation states probably pay 10x that $2M figure. the zero click market is an arms race and crypto wallets are the prize
pwn_herder state actors paying 10x is exactly right. the 2M dark web price is just retail. nsa level zero clicks probably run 20M+ and crypto wallets are priority targets
Noor A. the 20M+ figure for state actors is exactly why turning off iMessage is the bare minimum not paranoia. NSA doesnt buy zero clicks for pocket change
Tomislav P. NSA paying 20M+ for zero clicks while Trust Wallet tells users to turn off iMessage. the gap between threat actors and consumer defenses keeps widening
2M for an iOS exploit on the dark web. state actors probably pay 20M for the same bug. crypto wallets on phones are the soft underbelly
Theodor J. state actors paying 10x the dark web price means the real threat isnt some random hacker. its funded teams with specific crypto wallet targets
Theodor J. most people think not clicking links makes them safe. zero-click means the payload runs without any interaction. disable iMessage is the only real defense until Apple patches
2 million for an iOS zero-click on the dark web. state actors pay 10x that for the same exploit. your crypto wallet on a phone with iMessage enabled is a sitting duck
2 million for a zero-click that takes over your phone without a single tap. and people keep millions on mobile wallets. wild
Trust Wallet telling 60M users to disable iMessage was the loudest alarm bell. Apple still hasnt properly addressed zero-click vectors
the real issue is nobody updates their phone until something like this hits. zero-clicks arent new, people just dont take device security seriously
