As blockchain adoption grows, phishing risks escalate with increasing user activity. Cybercriminals employ sophisticated tactics—fake wallet websites, social media impersonation, malicious browser extensions, phishing emails, and counterfeit apps—to steal sensitive information and assets. These threats are diverse, complex, and often highly deceptive.
Common Phishing Techniques
Fake Wallet Websites
Phishers create near-identical replicas of legitimate wallet sites, tricking users into entering private keys or seed phrases. These fake sites are promoted via social media ads, emails, or search engine results.
Social Media Impersonation
Attackers pose as wallet support teams or community moderators on platforms like Twitter or Discord, sending fake messages to extract wallet credentials. High-profile cases include compromised accounts of Vitalik Buterin and the TON Foundation.
Malicious Browser Extensions
Some extensions secretly harvest data when users interact with Web3 applications.
Phishing Emails/Messages
Fraudulent communications mimic official alerts to lure victims into clicking harmful links.
Counterfeit Mobile Apps
Fake wallet apps on unofficial stores steal private keys upon installation. Modified Telegram APKs, for instance, have altered transaction addresses to divert funds.
