BlockSec Menggagalkan Percubaan Penggodam Untuk Mencuri $5 Juta Daripada ParaSpace

Walaupun penggodaman crypto telah menonjol sejak industri blockchain muncul, firma keselamatan blockchain bekerja keras untuk membawa keselamatan dan ketelusan kepada sektor tersebut. Kali ini, BlockSec, firma pengauditan kontrak pintar yang berdedikasi untuk membina infrastruktur keselamatan, telah dihalang a hacker from stealing $5 million in crypto funds from ParaSpace. 

ParaSpace ialah protokol pinjaman terdesentralisasi yang membolehkan pengguna meminjamkan atau meminjam pelbagai aset kripto pada blockchain Ethereum. Selain platform yang membolehkan pengguna meminjamkan NFT atau aset lain untuk menerima peratusan dalam bentuk faedah, ParaSpace membenarkan pengguna menggunakan dana yang dipinjam sebagai cagaran.

. kelemahan in the lending protocol of this smart contract enabled the hacker to borrow assets with fewer NFTs than required as collateral, allowing the attacker to drain liquidity protocol.

Fortunately, the exploiter failed in its first attempt to execute the transaction due to insufficient gas fees he has. Meanwhile, smart-contract auditing platform BlockSec detected the hack and modified the protocol in time to prevent the hacker from liquidating the crypto asset.

Abeerah Hashim, an Associate Editor at PrivacySavvy, a trusted cyber security website, initiated a warning as a group of crypto publishers reached out.

“Walaupun ia bagus untuk melihat BlockSec berjaya menghalang serangan ini, adalah penting untuk ambil perhatian bahawa kelemahan dalam sistem keselamatan masih boleh wujud. Memandangkan penyerang siber terus berkembang dan membangunkan kaedah baharu, adalah penting bagi syarikat untuk sentiasa menilai dan mengemas kini langkah keselamatan mereka untuk terus mendahului potensi ancaman.”

ParaSpace Dijeda Operasi Selepas Hack

Untuk mengulas kejadian itu, ParaSpace tweeted;

We alongside @BlockSecTeam have identified the cause of the exploit that occurred earlier on the ParaSpace protocol, and we are relieved to share that all user funds and assets on ParaSpace are safe and secure. No NFTs were compromised and financial losses to the protocol are minimal.

ParaSpace selanjutnya menyatakan platform telah menjeda semua operasi sehingga ia memadamkan kelemahan yang dikenal pasti melalui eksploitasi. Dalam erti kata lain, sebarang transaksi, pengeluaran atau deposit tidak boleh diteruskan kerana pasukan kontrak pintar itu sedang "memperbaiki kelemahan yang dikenal pasti."

Lei Wu, co-founder and CTO at BlockSec, diserlahkan that the internal security function automatically monitored the transaction linked to the hack. He said that the security function has the ability to prevent a hack in real-time.

The NFT lending protocol explained the exploit had cost the smart contract a loss of 50-150 Ethereum due to the attacker “swapping between tokens during the exploit.” But ParaSpace will allocate these funds to smart-contract from its pocket to make it nothing has been lost.

Interestingly, the hacker left an on-chain message after he failed to steal the funds, asking BlockSec to return some of the gas fees he spent during the ParaSpace hack. He menulis:

I couldn’t make it work because of a stupid gas estimation error. Since I lost a lot of money trying to make it work, it would be nice to get at least some of that back… good luck.

BlockSec has not rescued the funds from cybercriminals for the first time. The security firm recently saved $2.4 million from the Platypus Finance exploiters in February 2022. In April 2022, it dihalang hackers from stealing $3.8 million from Saddle Finance.
