Crypto Security 101: How Hacks Happen & How To Stay Protected | ZebPay
As the crypto industry continues to grow, so does its focus on security. With billions of dollars being traded and stored on both centralised finance (CeFi) exchanges and decentralised finance (DeFi) platforms, ensuring asset protection has become a top priority. While the space has seen its share of challenges, the good news is that crypto platforms are constantly evolving, adopting advanced security measures to safeguard users and build trust. From multi-layered authentication in CeFi to smart contract audits in DeFi, the industry is actively working to stay ahead of potential threats. In this blog, we’ll explore how security in crypto has strengthened over time, the proactive steps platforms take to protect funds, and how users can play a role in maintaining a secure trading environment.
Common Attack Vectors in CeFi and DeFi
CeFi Hacks
- Phishing Attacks – Fraudulent emails or websites tricking users into revealing login credentials
- Insider Threats – Employees abusing access for financial misconduct or compromising security through negligence, leading to financial losses.
- Hot Wallet Breaches – Attackers exploiting vulnerabilities in Internet-connected wallets.
- API Exploits – Unauthorised API access leading to unauthorised trades or fund withdrawals.
DeFi Hacks
- Smart Contract Vulnerabilities – Bugs in code allowing exploits, such as reentrancy attacks.
- Oracle Manipulation – Attackers influence price feeds to execute fraudulent trades.
- Flash Loan Exploits – Unsecured borrowing used to manipulate markets within a single transaction.
- Rug Pulls & Exit Scams – Developers draining liquidity pools or abandoning projects after fundraising.
