๐ The Top 10 Crypto Hacks of 2025 (So Far…)
1๏ธโฃ Bybit: The Billion-Dollar Breach
Date: Feb 18โ19, 2025
Loss: $1.46 Billion
Type: Access Control Exploit / Multisig Compromise
What began as a social engineering campaign ended in the largest hack in crypto history. Lazarus Group gained control over multisig wallets, bypassed human verification layers, and drained millions in ETH, BTC, and stablecoins.
๐ Lesson: Multisig isnโt enoughโprotect your people, not just your contracts.
2๏ธโฃ Cetus Protocol: The $223M Logic Bomb
Date: May 22, 2025
Loss: $223 Million
Type: Smart Contract Exploit
A reward calculation bug allowed minting of fake assets, resulting in a complete treasury drain within 3 minutes. A single misplaced validation cost the protocol dearly.
๐ Lesson: Smart contracts must be audited at every logic branchโno shortcuts.
3๏ธโฃ Cork Protocol: $12M Disappears in a Token Swap Mirage
Date: May 15, 2025
Loss: $12 Million
Type: Hook Exploit / Input Validation Error
Improper validation of custom smart contract functions allowed the attacker to fake token deposits and trigger protocol payouts.
๐ Lesson: Never launch with โout-of-scopeโ code in your audits.
4๏ธโฃ Chainge Finance: The $65M Slow Rug
Duration: Oct 2024โMay 2025
Loss: $65 Million
Type: Exit Scam / Operational Failure
It wasnโt flashyโbut it was deadly slow. Chainge Finance continued to accept deposits while disabling withdrawals. The slow collapse was later linked to the same founder behind the Multichain disaster.
๐ Lesson: Check the team. Audit the history. Trust is earned.
๐ Sector-by-Sector Breakdown
| Category | % of Total Loss | Est. Value Lost |
|---|---|---|
| Access Control Failures | 68% | $2.38B |
| Social Engineering / Phishing | 15% | $525M |
| Smart Contract Exploits | 12% | $420M |
| Rugpulls & Exit Scams | 5% | $175M |

๐จ Final Word from the Editor
The hacks are getting smarter, faster, and far more brutal. If you’re a builder: educate your team, simulate breaches, and test your protocols deeply. If you’re an investor: verify everything.
