CRYPTOCURRENCY RISES AND HACKERS AND SCAMMERS FIND NEW WAYS TO EXPLOIT PEOPLE.
As Cryptocurrency rises Hackers & scammers finds new ways to exploit Exchange & major Trading Exchange
A now-patched critical vulnerability in OpenSea, the world's largest non-fungible token (NFT) marketplace, could've been abused by malicious actors to drain cryptocurrency funds from a victim by sending a specially-crafted token, opening a new attack vector for exploitation.
The findings come from cybersecurity firm Check Point Research, which began an investigation into the platform following public reports of stolen cryptocurrency wallets triggered by free airdropped NFTs. The issues were fixed in less than one hour of responsible disclosure on September 26, 2021.
"Left unpatched, the vulnerabilities could allow hackers to hijack user accounts and steal entire cryptocurrency wallets by crafting malicious NFTs," Check Point researchers said.
As the name indicates, NFTs are unique digital assets such as photos, videos, audio, and other items that can be sold and traded on the blockchain, using the technology as a certificate of authenticity to establish a verified and public proof of ownership.
The modus operandi of the attack relies on sending victims a malicious NFT that, when clicked, results in a scenario whereby rogue transactions can be facilitated through a third-party wallet provider simply by providing a wallet signature to connect their wallets and perform actions on the targets' behalf. "Users should be hyper-aware of what they sign on OpenSea, as well as other NFT platforms, and whether it correlates with expected actions," the researchers said.
OpenSea said it hasn't identified any instances where this vulnerability was exploited in the wild but added it's working with third-party wallet services to "help users better identify malicious signature requests, as well as other initiatives to help users thwart scams and phishing attacks with greater efficacy."
"Blockchain innovation is fast-underway and NFTs are here to stay. Given the sheer pace of innovation, there is an inherent challenge in securely integrating software applications and crypto markets," said Oded Vanunu, head of products vulnerabilities research at Check Point. "Bad actors know they have an open window right now to take advantage of, with consumer adoption spiking, while security measures in this space still need to catch up."
