Recently, DeBot wallet is suspected to have been hacked, with hundreds of thousands of USDT transferred out. This incident once again sounds the alarm—how fragile is the asset security of ordinary users.

Wallet theft can only happen in these scenarios; understanding them can help you avoid risks.

**First Category: The Centralization of Private Keys in DEX Bot Products**
Many DEX Bot tools require users to upload private keys to servers, storing them in plaintext or decryptable forms. That sounds very dangerous—internal technical staff can access the private keys, and if hackers breach the defenses, the consequences are equivalent to an exchange being hacked. The security standards for such products must reach exchange-level security to be usable, otherwise the risk is sky-high. Moreover, from a compliance perspective, these services are not truly self-custody wallets; in most jurisdictions, they may need to fulfill KYC and AML obligations. If not compliant, they could face legal issues in the future.

**Second Category: The Code Risks of Self-Custody Wallets**
Code flaws, supply chain intrusions, compromised code repositories—all these can lead to private key leaks. Recently, a well-known wallet was exposed to a vulnerability, which was exactly this kind of issue.

**Third Category: Device Compromise on User End**
Your phone or computer could be infected with malware that listens to your keystrokes or clipboard; or you might have saved your seed phrase in a screenshot, and your photo app automatically uploads to the cloud. There’s a real case that’s quite outrageous—an internal employee at a large photo company programmed a script to traverse user backups, specifically filtering images containing seed phrases. Think about it: no matter how secure your wallet is, if the user’s device is compromised, everything is pointless.

Ultimately, the primary responsibility for asset security always lies with you.
