5. Risk Alert

The crypto industry has recently experienced multiple security incidents involving social engineering and permission-based infiltration attacks. Rather than relying solely on smart contract vulnerabilities, attackers are increasingly impersonating official emails, fake customer support accounts, malicious plugin updates, and phishing verification portals to trick project members or ordinary users into revealing access credentials and wallet permissions.

These attacks are highly deceptive. Even users who do not directly expose seed phrases may still suffer losses after signing malicious transactions or installing fake browser extensions. Meanwhile, phishing campaigns disguised as “protocol upgrades,” “security verifications,” or “airdrop compensation portals” have also become increasingly common,诱导 users into granting dangerous wallet approvals.

Users are advised not to trust unsolicited social-media messages or unknown links. All wallet-related operations should be verified through official channels, signature requests should be reviewed carefully, and unnecessary wallet permissions and browser plugins should be removed regularly to strengthen account and asset security awareness while protecting digital assets safely.
