North Korean hackers (such as Lazarus) usually do not give advance "warnings." The core of threat assessment is identifying pre-attack signs in the attack chain, rather than tracing back after assets are stolen. You can quickly self-assess through the following dimensions.

🔍 Risk Self-Assessment Checklist

If the following signs appear, it indicates you may have been listed as a potential target or are in the early stages of an attack:

Unusual social contacts

Receiving unfamiliar "high-paying Web3 job offers" private messages, or being asked by "exchange customer service/project team" to click links to verify accounts, download test packages, or share screens.

Warning: North Korean hackers are skilled at impersonation, using LinkedIn and Telegram for "romance scam" style deception.

Device abnormal behavior

Computer fans spinning wildly for no reason, unfamiliar processes (such as CoreKitAgent or other impersonators) appearing, or browsers automatically redirecting to non-official domain pages.

Typical tactics: planting backdoors via fake Zoom update packages or malicious npm packages, monitoring and stealing wallet files.

Transaction phase anomalies

Copying wallet addresses and pasting them, where the first and last characters are similar but the middle has been tampered with (clipboard hijacking).

When connecting wallets, DApps requesting permissions beyond what is necessary (such as requesting unlimited approve).

🛡️ Urgent Troubleshooting and Stop Loss

If you suspect you've been compromised, immediately perform the following actions:

Physical isolation: disconnect from the internet and shut down immediately to prevent malicious software from continuing data transmission. Never re-enter mnemonic phrases on this device.

Asset migration: generate a new wallet on a completely clean device (or mobile hotspot), and transfer all assets to the new address. Do not operate on the infected device.

Environment cleanup: perform full disk antivirus scans on commonly used devices, focusing on browser extensions and recently installed unfamiliar software.

📉 Long-term Defense Strategies

Physical isolation: use hardware cold wallets for large assets to completely isolate from network attacks.

Information minimization: do not publicly share wallet addresses and holdings on social platforms to reduce the chance of being "tagged."

Source verification: only download software from official websites; treat Telegram private message links as high risk.

For ordinary users, as long as you do not click on unfamiliar links, do not install unknown software, and have never exposed your mnemonic phrase online, the probability of being "targeted and blown up" by North Korean hackers is extremely low. True threats often stem from "greed" and "negligence." #Gate广场四月发帖挑战
