What to Do If Your Crypto Wallet May Be Compromised

The moment you suspect your crypto wallet is compromised, panic is the enemy. Crypto theft often unfolds over minutes, and the right calm sequence of actions can save the funds an attacker has not reached yet. This guide is a step-by-step response plan for the most common scenarios — a malicious approval, a possible drainer, or an exposed recovery phrase.

A reminder: crypto transactions are usually irreversible, and this is general guidance, not legal or financial advice. Act fast but deliberately, and adapt to your situation.

First: assess what may be exposed

Before acting, quickly determine what is at risk, because it changes everything:

• Did you sign a transaction or approval on a suspicious site? The attacker may be able to move specific tokens.
• Did you enter your recovery phrase anywhere, or could it have been photographed or stolen? Then the entire wallet is compromised — every asset and every address derived from that phrase.
• Is the affected account on an exchange rather than self-custody? The recovery path is different (see below).

This triage decides whether you are containing one leak or evacuating the whole wallet.

If your recovery phrase is exposed

Assume the wallet is fully and permanently compromised. You cannot "change the password" — the phrase is the master key.

1. Create a brand-new wallet with a freshly generated recovery phrase on a clean, secure device.
2. Move any remaining assets immediately to the new wallet's addresses. Speed matters; race the attacker.
3. Never reuse the exposed phrase or any address derived from it again.
4. If gas/network fees are a problem for moving small balances, prioritize the highest-value assets first.

If you only signed a malicious approval

You may be able to contain it without abandoning the wallet, but be cautious.

1. Revoke the malicious approval using a token-approval management tool, so the contract can no longer move your tokens.
2. Move at-risk assets to a safe wallet as a precaution.
3. If you are unsure how deep the exposure goes, treat it like a phrase compromise and migrate to a fresh wallet.

If it is an exchange account

With custodial accounts, the exchange controls the keys, so the response is account security, not key migration.

1. Change the password and enable or reset two-factor authentication (prefer an authenticator app or hardware key).
2. Revoke active sessions and connected apps/API keys.
3. Contact the exchange's official support immediately — through the app or the bookmarked official site, never a number from a search ad or DM, which are favorite scam vectors.
4. Set a withdrawal whitelist once secured.

Afterward: clean up and learn

Once funds are safe: scan your device for malware, reset compromised passwords, and review how the breach happened — a fake site, a malicious approval, a leaked phrase. Beware of "recovery" scammers who appear after a theft promising to retrieve funds for a fee; they are a second wave of the same attack. No legitimate service can reverse on-chain transactions.

Bottom line

If your wallet may be compromised, triage first: an exposed recovery phrase means evacuate everything to a new wallet immediately; a single bad approval may be contained by revoking it; an exchange breach means lock the account and call official support. Move quickly, trust no unsolicited "helper," and rebuild on a clean device.
