BlockSec spriječio pokušaj hakera da ukradu 5 milijuna dolara od ParaSpacea
Iako su kripto hakiranja istaknuta otkad se pojavila blockchain industrija, sigurnosne tvrtke blockchaina naporno rade na uvođenju sigurnosti i transparentnosti u sektor. Ovaj put, BlockSec, tvrtka za reviziju pametnih ugovora posvećena izgradnji sigurnosne infrastrukture, to je učinila spriječiti a hacker from stealing $5 million in crypto funds from ParaSpace.
ParaSpace je decentralizirani protokol za posuđivanje koji korisnicima omogućuje posuđivanje ili posuđivanje različitih kripto sredstava na Ethereum blockchainu. Osim platforme koja korisnicima omogućuje posuđivanje NFT-ova ili druge imovine kako bi dobili postotak u obliku kamata, ParaSpace omogućuje korisnicima korištenje posuđenih sredstava kao kolaterala.
Korištenje električnih romobila ističe 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 BlockSec uspješno sprječava ovaj napad, važno je napomenuti da ranjivosti u sigurnosnim sustavima još uvijek mogu postojati. Dok se cyber napadači nastavljaju razvijati i razvijati nove metode, za tvrtke je ključno da redovito procjenjuju i ažuriraju svoje sigurnosne mjere kako bi bile ispred potencijalnih prijetnji.”
ParaSpace je pauzirao operacije nakon hakiranja
Za komentar o incidentu, ParaSpace Tweetano;
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 primijetio da je platforma pauzirala sve operacije dok nije izbrisala ranjivosti identificirane kroz exploit. Drugim riječima, bilo koja transakcija, povlačenje ili uplata ne može se nastaviti jer tim pametnog ugovora trenutno "ispravlja 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 spriječiti hackers from stealing $3.8 million from Saddle Finance.
