We blocked an attack on @ParaSpace_NFT and rescued 2900 eth. Please contact us asap. Dmed 45 minutes ago but get no response.- We help @Platypusdefi recover 2.4M USDC from the attacker contract successfully! BlockSec will always be here to secure the whole ecosystem.
- .@KyberSwap was exploited due to tick manipulation and double liquidity counting. In summary, the attackers borrowed a flash loan and drained the pools with low liquidity. By executing swaps and altering positions, they manipulated the current prices and ticks of the victimized
Kyber being exploited on all chains rn. here's an example tx on base. 20m+ lost already - Our initial analysis of the Cream Finance attack: tx.blocksecteam.com/tx/0x0fe254207… @Mudit__Gupta @banteg @CreamdotFinance

Another attack cause the loss ~$14m! explorer.phalcon.xyz/tx/eth/0x2e7dc… - Looks like an MEV bot has been attacked(tx.blocksecteam.com/ETH/0x6c30c0b8…) due to the lack of a check for the sender. @Mudit__Gupta
