Ankr geeft ex-werknemer de schuld van $5 miljoen uitbuiting
- Ankr previously acknowledged that a stolen deployer key that was used to update the protocol’s smart contracts was behind the attack. However, it did not reveal how the deployer key was obtained at the time.
The Ankr team, which on December 1 suffered a $5 million hack, has announced on its website that a former employee was responsible for the attack on the protocol. The DeFi platform gezegd that the former team member was able to carry out the supply chain attack by inserting harmful code into a package of upcoming updates to the team’s internal software. The malicious code, once updated, produced a security flaw that gave the attacker access to the platform’s server and stole the team’s deployer key.
Door de fout kon een gebruiker 6 biljard aBNBc-tokens slaan, wat de hacker snel omgezet in Binance Coin (BNB) voordat ze naar Tornado Cash, een crypto-mixservice, worden gestuurd. De aanvaller kon de BNB-tokens omwisselen voor 5 miljoen USDC.
Ankr said it has notified the appropriate authorities and is working to have the attacker prosecuted. The team is also working to improve security to safeguard future access to its keys. The team said in a statement,
De exploit was deels mogelijk omdat er een single point of failure was in onze ontwikkelaarssleutel. We zullen nu multi-sig-authenticatie implementeren voor updates waarvoor goedkeuring van alle sleutelbewaarders nodig is gedurende tijdgebonden intervallen, waardoor een toekomstige aanval van dit type uiterst moeilijk, zo niet onmogelijk wordt. Deze functies zullen de beveiliging van het nieuwe ankrBNB-contract en alle Ankr-tokens verbeteren.
Furthermore, Ankr has pledged to enhance HR procedures and will mandate that all workers, including those who work remotely, face increased background checks. The team also promised to review access privileges to ensure that only employees who need access to critical information will have clearance to access it. The DeFi protocol also plans to install new notification systems to notify the staff more promptly if a problem occurs.
