BlockSec-ek ParaSpacetik 5 milioi dolar lapurtzeko saiakerak zapuztu ditu
Crypto-hack-ak blokeoen industria sortu zenetik nabarmenak izan diren arren, blockchain segurtasun enpresak gogor lanean ari dira sektoreari segurtasuna eta gardentasuna ekartzeko. Oraingoan, BlockSec-ek, segurtasun-azpiegitura bat eraikitzera dedikatzen den kontratu adimendunaren auditoretza-enpresa batek, du eragotzi a hacker from stealing $5 million in crypto funds from ParaSpace.
ParaSpace mailegu-protokolo deszentralizatua da, erabiltzaileek Ethereum blockchain-en hainbat kripto-aktibo maileguan edo maileguan hartzeko aukera ematen diena. Erabiltzaileek NFTak edo beste aktibo batzuk mailegatzeko aukera ematen dien plataformaz gain, interes moduan ehuneko bat jasotzeko, ParaSpace-k erabiltzaileei mailegatutako funtsak berme gisa erabil ditzakete.
The ahultasun 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.
"BlockSec-ek eraso hau arrakastaz saihesten ikustea zoragarria den arren, ezinbestekoa da segurtasun sistemetan ahultasunak egon daitezkeela ohartzea. Zibererasotzaileek eboluzionatzen eta metodo berriak garatzen jarraitzen duten heinean, funtsezkoa da enpresek beren segurtasun-neurriak aldian-aldian ebaluatzea eta eguneratzea, balizko mehatxuei aurrea hartzeko".
ParaSpace-k eten zituen eragiketak Hack ondoren
Gertaera komentatzeko, 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-k gaineratu du plataformak eragiketa guztiak pausatu zituela esplotazioaren bidez identifikatutako ahultasunak ezabatu zituen arte. Beste era batera esanda, edozein transakzio, erretiratzea edo gordailua ezin da aurrera egin, kontratu adimendunaren taldea gaur egun "identifikaturiko ahuleziak konpontzen" ari baita.
Lei Wu, co-founder and CTO at BlockSec, nabarmendu 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 idatzi:
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 eragotzi hackers from stealing $3.8 million from Saddle Finance.
