Understanding Web3 Phishing Threats
As blockchain adoption grows, phishing risks escalate with increased user activity. Attackers employ tactics like:
- Fake Wallet Websites: Mimicking legitimate platforms to steal private keys.
- Social Media Impersonation: Posing as admins or customer support.
- Malicious Browser Extensions: Injecting code to capture sensitive data.
- Phishing Emails/Messages: Spoofing trusted entities.
- Fraudulent Apps: Distributing tampered software (e.g., modified Telegram clients).
OKX Web3 Wallet analyzed community-reported incidents to identify 4 major phishing scenarios, providing actionable countermeasures below.
Primary Sources of Malicious Activity
1. Twitter Replies on Trending Projects
Scammers clone official accounts (matching logos, names, verification badges) but alter the handle slightly (e.g., substituting l with 1). They often reply to genuine tweets with phishing links.

2. Hijacked Official Channels
Compromised Twitter/Discord accounts (e.g., Vitalik’s past breaches) spread fake announcements. Always verify links through multiple sources.
3. Google Search Ads
Malicious domains appear as "official" in search ads. Double-check URLs before clicking.
4. Fake Applications
Fake wallet apps steal private keys. Only download from official stores or project websites.
