BlockSec osujetio pokušaj hakera da ukradu 5 miliona dolara iz ParaSpace-a
Iako su kripto hakovi bili istaknuti otkako se pojavila blockchain industrija, firme za sigurnost blokčeina naporno rade na tome da unesu sigurnost i transparentnost u sektor. Ovog puta, BlockSec, revizorska firma sa pametnim ugovorom posvećena izgradnji bezbednosne infrastrukture, jeste sprečeno a hacker from stealing $5 million in crypto funds from ParaSpace.
ParaSpace je decentralizirani protokol pozajmljivanja koji omogućava korisnicima da posuđuju ili posuđuju različita kripto sredstva na Ethereum blockchainu. Osim što platforma omogućava korisnicima da pozajmljuju NFT ili drugu imovinu kako bi dobili procenat u vidu kamate, ParaSpace omogućava korisnicima da koriste pozajmljena sredstva kao kolateral.
The ranjivost 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.
“Iako je sjajno vidjeti kako je BlockSec uspješno spriječio ovaj napad, važno je napomenuti da ranjivosti u sigurnosnim sistemima i dalje mogu postojati. Kako sajber napadači nastavljaju da se razvijaju i razvijaju nove metode, za kompanije je ključno da redovno procjenjuju i ažuriraju svoje sigurnosne mjere kako bi bile ispred potencijalnih prijetnji.”
ParaSpace je pauzirao operacije nakon hakovanja
Za komentar incidenta, 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 je dalje naveo da je platforma pauzirala sve operacije dok nije izbrisala ranjivosti identifikovane eksploatacijom. Drugim riječima, nijedna transakcija, povlačenje ili depozit ne mogu se nastaviti jer tim pametnog ugovora trenutno „popravlja identificirane ranjivosti“.
Lei Wu, co-founder and CTO at BlockSec, istaknut 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 napisao:
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 sprečeno hackers from stealing $3.8 million from Saddle Finance.
