NFT Hacks on the Rise 

Regrettably, the NFT industry has continued to witness numerous cases of security breaches since its boom in 2021. Barely three months ago, a security breach led to the pilfering of approximately 60 Ether (ETH) worth of NFTs from Arthur0x, the founder of DeFiance Capital. 

As reported, the siphoned funds were then sold on OpenSea. In April, Yuga Labs, the developer of the Bored Ape Yacht Club non-fungible tokens suffered a hacking attack that resulted in huge losses. 

As reported, the exploiter gained unauthorized access to the Instagram account of BAYC and consequently sent a phishing post to users. Many of the users reportedly clicked on the link attached to the phishing post which abruptly connected their crypto wallets to the hacker’s “smart contract”. With this, the hacker pilfered four Bored Apes and NFTs estimated at $3m.

More so,  Hubspot endured the same fate in March, a development that affected BlockFi, Swan Bitcoin, NYDIG, and Circle. Findings of the exploitation revealed that the names, phone numbers, and email addresses of users of these platforms were leaked to an outside party.
