Venus Protocol Dealer Loses $30 Million in Main Error, Cyvers Confirms

The attacker gained entry by tricking the sufferer into approving a malicious transaction, which gave limitless permissions to switch belongings from the pockets.

The stolen tokens included round $19.8 million in vUSDT, $7.15 million in vUSDC, $146,000 in vXRP, $22,000 in vETH, and even 285 BTCB, representing what observers described as “generational wealth.”

Defi analyst Ignas additionally weighed in, noting that Venus itself “labored as meant” and that the incident stemmed from the attacker exploiting pre-approved authorizations from the compromised pockets.

“One dangerous approval and growth—you’re carried out. That’s the darkish aspect of DeFi: open approvals are highly effective, but additionally lethal when you’re not cautious,” wrote analyst Crypto Jargon.

The sentiment was echoed throughout the neighborhood as warnings resurfaced about greatest practices: frequently revoking approvals, avoiding unverified hyperlinks, and utilizing {hardware} wallets as an alternative of relying solely on scorching wallets.

Cyvers confirmed this in a press release to BeInCrypto:

“Sure, consumer aspect error not at protocol degree,” Cyvers articulated.

The stolen funds stay unswapped, held within the attacker’s contract tackle.

“This incident exhibits that even skilled DeFi customers stay weak to stylish phishing schemes. By tricking the sufferer into granting token approvals, the attacker was in a position to drain $27M from a Venus Protocol in a single transaction” mentioned Hakan Unal Senior Safety Operation Lead at Cyvers.

Bunni DEX Exploit Drains $8.4 Million

In a separate incident, Bunni, a decentralized alternate (DEX) constructed on Uniswap v4, suffered an exploit that drained over $8.4 million throughout Ethereum and UniChain.

In contrast to the Venus case, this was a real vulnerability on the protocol degree.

Bunni introduced that it had paused all sensible contract capabilities throughout networks as its group investigates:

“The Bunni app has been affected by a safety exploit. As a precaution, we’ve paused all sensible contract capabilities on all networks,” the community confirmed.

Based on GoPlus Safety, the exploit stemmed from weaknesses in Bunni’s customized Liquidity Distribution Perform (LDF).

Victor Tran, a blockchain developer, defined how the attacker manipulated the curve with fastidiously sized trades.

By repeatedly triggering miscalculations throughout liquidity rebalancing, the exploiter was in a position to withdraw extra tokens than they need to have, draining swimming pools earlier than finalizing the assault with two swap steps. Tran emphasised that whereas Bunni’s hook was compromised, Uniswap v4 itself remained unaffected.

The dual incidents spotlight the delicate stability between innovation and safety in decentralized finance (DeFi). Venus Protocol’s loss highlights the human aspect—the place a single click on can erase fortunes—whereas Bunni’s exploit reveals how precision flaws in novel mechanisms can depart liquidity uncovered.

Because the DeFi sector continues to develop, each consumer training and protocol rigor will stay vital. In a market the place billions are at stake, one mistake—whether or not human or technical—can show devastating.
