Two recent incidents involving crypto wallet users serve as a reminder that a hardware wallet can remain technically unbroken while an attacker still walks away with funds. The weak point is rarely the device itself. It is the person holding it, the software connected to it, or the transaction being approved through it.
What the Two Incidents Reveal About Hardware Wallet Security
Hardware wallets store private keys offline, physically separated from internet-connected devices. That design protects the keys themselves. But as CryptoSlate has reported, a hardware wallet can stay secure while everything around it fails.

The incidents under discussion follow a pattern seen repeatedly in crypto security: the device is never touched. Instead, attackers target the user, the companion app, or the moment a transaction is submitted for approval. The hardware wallet signs whatever instruction it receives. If that instruction is fraudulent, the result is the same as a direct theft. For related coverage, see Cosmos Hub Resumes, Ledger ATOM Wallet Issues Persist.
This pattern is especially relevant for users who believe that owning a hardware wallet removes most of their risk. It reduces one category of risk significantly. It does not eliminate risk from deception. Supply chain attacks, where malicious actors tamper with hardware or software before it reaches the user, are a separate but related concern, as covered in reporting on the $7 million crypto theft operation targeting wallet supply chains.

Why a Secure Device Does Not Guarantee a Safe Transaction
The core issue is that a hardware wallet confirms what it is told to confirm. If a user is tricked into approving a transaction that drains their funds, the wallet performs exactly as designed. The keys were never stolen. The user authorized the transfer. For related coverage, see UK Crypto Firms Face New FCA Authorization Process as Applications Open.
Attackers use several methods to reach this outcome. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) identifies social engineering as the primary technique: manipulating a person into taking an action or disclosing information they otherwise would not. In a crypto context, that can mean a fake support agent asking for a recovery phrase, a phishing site that mirrors a legitimate wallet interface, or a malicious token approval embedded in what looks like a routine transaction.
Recovery phrases, the 12 or 24-word sequences used to restore a wallet, are the most sensitive piece of information a hardware wallet user controls. Anyone who obtains that phrase can recreate the wallet on any device and move the funds without needing physical access to the original hardware. No hardware security feature protects a recovery phrase that the user hands over voluntarily.
Token approvals are a subtler risk. When a user interacts with a decentralized application, a program running on a blockchain that executes automatically without a middleman, they are often asked to approve the application’s access to their tokens. A malicious approval can grant an attacker unlimited access to a specific asset. The hardware wallet will display a confirmation prompt, but users who do not read it carefully may approve without understanding what they are signing.
Steps That Reduce Exposure
The most direct protection is a firm rule about recovery phrases: never enter them into a website, mobile app, browser extension, support chat, or any form that appears online. Legitimate wallet manufacturers and support teams do not ask for recovery phrases under any circumstances. Any request for one is an attack.
Before signing any transaction, verify the details on the hardware wallet’s own screen, not just the software interface on the connected computer or phone. The wallet’s display shows the actual instruction being signed. If the details do not match what you expected, reject the transaction. Unfamiliar token approval requests deserve particular scrutiny.
Software used alongside a hardware wallet, including companion desktop apps and browser extensions, should be downloaded only from official sources. Firmware updates should come exclusively through the manufacturer’s official update process. The approach taken by hardware wallet makers like BitBox, which avoids requiring a new backup phrase for expanded features, reflects a broader industry awareness that reducing recovery-phrase exposure is itself a security improvement.
Independently verify any wallet address, support contact, or software link before using it. Attackers frequently register domains and social accounts designed to look like official channels. A brief confirmation step, checking a manufacturer’s official website directly rather than following a link from an email or social post, removes a large category of risk without requiring technical expertise.
Hardware wallets remain one of the strongest tools available for protecting crypto holdings. Their protection is meaningful and real. But that protection covers the private key, not the decisions made around it. Keeping those decisions deliberate and skeptical is the part no device can do for you.
