How to fix it
- If you keep crypto on an exchange, move long-term holdings to a wallet you control and turn on withdrawal address allow-lists.
- Use app-based or hardware-key two-factor authentication on exchange and wallet accounts, not SMS codes.
- Treat unexpected job offers, coding tests or trading apps sent over chat as suspicious; they are a common lure in crypto theft.
- Companies holding crypto: require more than one approver for large transfers and keep signing keys on separate, locked-down devices.
How to detect it
Signs to watch for:
- Withdrawals to new addresses, or at unusual sizes or times.
- New devices, API keys or withdrawal addresses added to exchange or wallet accounts.
- Developer tools, packages or 'trading' apps installed right after a recruiter or job chat.
