BlockSec onemogočil hekerski poskus kraje 5 milijonov dolarjev iz ParaSpacea
Čeprav so bili vdori v kriptovalute vidni, odkar se je pojavila industrija veriženja blokov, se podjetja za varnost veriženja blokov močno trudijo zagotoviti varnost in preglednost v sektorju. Tokrat je to storilo BlockSec, revizijsko podjetje za pametne pogodbe, namenjeno izgradnji varnostne infrastrukture preprečiti a hacker from stealing $5 million in crypto funds from ParaSpace.
ParaSpace je decentraliziran protokol posojanja, ki uporabnikom omogoča posojanje ali izposojo različnih kripto sredstev v verigi blokov Ethereum. Poleg platforme, ki uporabnikom omogoča posojanje NFT-jev ali drugih sredstev, da prejmejo odstotek v obliki obresti, ParaSpace uporabnikom omogoča uporabo izposojenih sredstev kot zavarovanja.
O ranljivost 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.
»Čeprav je čudovito videti, da BlockSec uspešno preprečuje ta napad, je ključnega pomena vedeti, da lahko ranljivosti v varnostnih sistemih še vedno obstajajo. Ker se kibernetski napadalci še naprej razvijajo in razvijajo nove metode, je za podjetja ključnega pomena, da redno ocenjujejo in posodabljajo svoje varnostne ukrepe, da ostanejo pred morebitnimi grožnjami.«
ParaSpace je začasno ustavil operacije po vdoru
Za komentar o incidentu, 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 nadalje opozoril, da je platforma ustavila vse operacije, dokler ni izbrisala ranljivosti, ki so bile ugotovljene z izkoriščanjem. Z drugimi besedami, nobena transakcija, dvig ali polog se ne more nadaljevati, saj ekipa pametne pogodbe trenutno »odpravlja ugotovljene ranljivosti«.
Lei Wu, co-founder and CTO at BlockSec, poudarjeno 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 Napisal:
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 preprečiti hackers from stealing $3.8 million from Saddle Finance.
