The last 48 hours have been a cold shower for the DeFi sector. While the market is rising, technical vulnerabilities and the human factor remind us of the cost of mistakes. Let's analyze two high-profile cases from March 2026.
🔴 Venus Protocol: Attack through price manipulation
On March 15, hackers attacked the lending platform Venus. The target was the recently added token THE.
How it worked: Malicious actors exploited the low liquidity of the token to manipulate the price oracle. Artificially driving the price of $THE from $0.27 to nearly $5, they used it as collateral to withdraw liquid assets ($BTC , $BNB , $CAKE ) totaling over $3.5 million.
Status: The Venus team promptly suspended the THE market. This once again proves: liquidity is safety.
📉 Aave: Loss of $50.4 million with one click
A case that will go down in history as one of the most expensive trader mistakes.
What happened: A user attempted to exchange $50.4 million in aEthUSDT tokens through the Aave interface. Despite the system's warning about critical slippage, the transaction was manually confirmed.
Result: Due to low liquidity at the moment, the trader received assets worth only $36,000. Almost $50 million simply 'dissolved' in liquidity pools.
Ray of hope: Aave founder Stani Kulechov promised to return approximately $600,000 in fees to the affected party as a goodwill gesture, and the protocol is already preparing to launch 'Aave Shield' to block such operations in the future.
💡 Your security checklist:
Slippage Tolerance: Never ignore the warning 'High Slippage', especially on amounts >$10k.
Liquidity of the asset: Before using new tokens (like THE) as collateral, check their trading volumes.
Diversification: Even top protocols have 'black swan' risks.
Keep your funds safe and remember: in DeFi, you are your own bank! 🛡️
