Premint Attacked
One of the most important non-fungible token breaches of the year resulted within the theft from Premint NFT platform customers of a minimum of 314 blockchain entries, totaling around $375,000.
According to the crypto security company CertiK, the difficulty started with an injection of malicious JavaScript and affected wallets storing NFTs like Bored Ape boat club and Oddities. Premint tweeted that affected users received a pop-up requesting them to substantiate their ownership of their wallet. Users of the web site can join up to be included to a database of prospective buyers of latest NFT projects.
We are actively working to get a full list of wallets that had assets taken from them.
These are the wallets that Etherscan have flagged for stealing assets.

The message also persuaded users to enable a “SetApprovalForAll” feature in their wallets, allowing hackers to steal money from their accounts. Premint claims that only a “relatively small number of users” were fooled by the prompt which it’s increased security.
SetApprovalForAll is created to enable users of decentralized finance platforms to instantly consent to the transfer of particular tokens that are pre-selected by an underlying Smart contract at a later time. Threat actors profit of the feature to transfer all of the tokens belonging to other users to their own wallets.
The hack has been effectively closed, and PREMINT has updated their website as of this writing.
Users can now log into the platform using their Twitter or Discord accounts rather than wallets, per an update pinned to the web site by PREMINT. this can be secure and much more convenient, especially on mobile devices.
Safety Measures
The warning was posted earlier on Twitter by the Permit team, telling users to revoke access to their wallets if they think their wallets were compromised within the hack and to not approve any transactions that ask them to “set approvals for all.” For a fix, the web site was momentarily taken offline.
The platform briefly clean up its website and advised disabling the “set approval for all” feature using Revoke Cash or Etherscan and relocating any assets to a distinct wallet. With the utilization of an incident report form, the business is gathering a listing of stolen items and using it to trace their whereabouts.
The website was operational at the time this was written. Users now not must sign on to the web site using their wallets due to a Premint update. Users can now log back to the platform using their Twitter or Discord accounts instead of their wallets. It’s much safer and more practical. Particularly on mobile.
Furthermore, PREMINT informed its community that they’re trying to recover affected users’ wallets and their stolen assets. “We are actively working together to urge a full list of wallets that had assets taken from them.”
The number of NFT hacks has significantly increased since last year, with PREMINT being the foremost recent victim. Earlier on Friday, a hacker targeted NFT Artist DeeKay’s Twitter account. consistent with reports, the attack caused NFT losses of $150,000.
Being extra cautious while approving any transactions is now more crucial than ever because of the rise in NFT scams.
