Introduction
The crypto space, as a field full of opportunities and risks, has frequently become the focus in recent years due to asset theft and account security issues. This article discusses how to enhance personal security awareness and protective capabilities in the crypto space based on recent case analyses and practical experience.
The Truth and Lessons of Facts
In incidents of asset theft in the crypto space, victims often do not fully disclose the facts, leading to misunderstandings about the events. By analyzing some cases, the following main reasons for theft can be summarized:
Lack of Security Awareness: For example, clicking on phishing links, authorizing unknown transactions, etc.
Insufficient Device and Account Security: Such as storing mnemonic phrases in WeChat, not enabling two-factor authentication.
Technical Vulnerabilities or Operational Errors: Certain chain characteristics may be maliciously exploited.
The commonality among these incidents is that victims often overlook their own security responsibilities or lack sufficient awareness of potential risks.
Specific Measures to Enhance Security in the Crypto Space
To avoid similar issues, we can take the following measures:
1. Mnemonic Phrase and Key Management
Handwritten Mnemonic Phrases: Avoid storing mnemonic phrases on any network-connected devices (such as WeChat, cloud notes, etc.).
Physical Isolation: Store mnemonic phrases in secure physical media, such as fireproof and waterproof metal cards.
2. Device and Tool Selection
Avoid Using Huawei Phones: When involved in crypto transactions, try to choose Apple devices, especially iPhone and Mac, due to their higher ecosystem security.
Use Chrome Browser: It is recommended to use Chrome or other mainstream browsers, avoid using unknown browsers.
3. Account Security Settings
Enable Two-Factor Authentication: Activate Google Authenticator verification for accounts such as exchanges, email, and social media.
Disable Cloud Sync: Ensure that the cloud sync feature of Google Authenticator is turned off to avoid secondary verification failure due to account leakage.
Use Hardware Security Tools: Such as YubiKey, to add a layer of physical verification.
4. Daily Operation Precautions
Cross-verify Information: Verify the authenticity of URLs and links through multiple channels to avoid clicking on phishing links.
Avoid Stranger Links: Do not communicate with strangers on platforms like Telegram or Discord, and do not click on links they provide.
Treat Airdrops with Caution: Airdrops often come with numerous phishing links, do not click casually.
5. Security Precautions for Specific Chains and Wallets
Solana Wallet: Solana's account permissions can be dynamically changed through contracts, so special care must be taken during interactions to avoid signing unknown transactions.
Dynamic Verification: Set dynamic withdrawal limits on exchanges to avoid large asset theft due to permission issues.
Lessons We Can Learn
Do not easily trust unilateral statements: Many facts require multiple reversals to approach the truth.
Security Responsibility Lies with Oneself: Whether it’s a wallet or an exchange, the user is the primary responsible person for asset security.
Learn Security Knowledge: Regularly pay attention to developments in the security field and learn the latest protective techniques.
Summary
Security issues in the crypto space are never resolved overnight; hackers' attack methods continuously evolve, and we need to continuously enhance our security awareness and protective capabilities. Remember the following points:
Don’t Trust, Verify: Do not trust any single source, verify repeatedly.
Diversify Assets: Store assets in a diversified manner to reduce the risk of single point failure.
Stay Vigilant: Whether it’s technical operations or daily habits, prioritize security.
Only when each of us takes responsibility for our own assets can we better protect ourselves in the complex environment of the crypto space and avoid becoming the next victim.
