Device Security

Define the security boundary first

Verification focus

When working with Device Security, start by keeping system updates, screen locks, and app permissions in the same context. Show that wallet security is not only on-chain; device permissions, system hygiene and network conditions also affect address and signature integrity. A familiar label or icon is not enough on its own; the active network, account, address, contract or transaction record should agree with the action you intend to take. For consequential actions, understanding exactly what is being requested matters more than moving quickly through a confirmation screen.

A practical Device Security workflow can follow a consistent sequence: confirm the source and destination, review app permissions, then verify clipboard risk in the correct network context, and finally inspect public Wi-Fi together with the possible on-chain consequence. Only after that review should you sign or submit. Keep non-secret evidence such as a transaction hash or contract address so the result can be checked later.

The central risk around Device Security is that A compromised device can alter clipboard contents, displays or input flows, causing incorrect confirmations even when the wallet software itself is functioning. If an unexpected network switch, unfamiliar contract, excessive approval, changed address or urgency tactic appears, stop before confirming. Seed phrases, private keys and verification codes are never normal troubleshooting material; imtoken staff will not ask for them and they should not be submitted through websites, chats or remote-control tools.

Recognize the most common threat scenarios

Key observations during the workflow

For “Recognize the most common threat scenarios”, screen locks establishes the starting point, app permissions helps explain whether the process is progressing as expected, and clipboard risk is often the detail that can be cross-checked against wallet history or public on-chain data. If those facts conflict, stop and verify the source again. Transfers, signatures, approvals and cross-layer actions deserve a complete review even when the interface looks familiar.

It also helps to separate interface information from verifiable on-chain facts. clipboard risk may describe the intent of an action and public Wi-Fi may provide useful status context, but important decisions should still be checked against remote-control software and the relevant network record. Wallet labels, token symbols, DApp copy and promotional language can all be imitated, so familiarity is not proof of authenticity.

• Review system updates in the correct network context.
• Review screen locks in the correct network context.
• Review app permissions in the correct network context.
• Review clipboard risk in the correct network context.
• Review public Wi-Fi in the correct network context.

What to do after noticing something suspicious

Do not let urgency replace judgment
