Multiple users have reported unauthorized charges to their EtherFi virtual cards despite no transactions or pre-authorizations being made. Cryptocurrency opinion leader @keyahayek believes the issue may stem from a vulnerability in EtherFi's upstream or downstream partners and advises users to suspend use of the card. EtherFi CEO Mike Silagadze stated that the company is working with its credit card partners on the investigation and has confirmed that all affected users will receive a refund.
