# Malware Malware (viruses, trojans, and etc.) that finds its way onto a user's computer can steal private keys and send them to an attacker. Malware may be used with another technique like phishing, where an attacker tricks a user into downloading a malicious file with a malware payload. **Mitigation:** * Use a heterogenous hardware and software system for storing your funds, including hardware wallets. This creates a more difficult environment for malware to operate in. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
