Virtual Credit Cards: How They Work, Benefits, and Security Features

 

Virtual credit cards are digital versions of traditional credit cards, designed to enhance security in online transactions. Instead of using a physical card number, they generate a unique number for each purchase, reducing the risk of data breaches and fraud. If compromised, a virtual card can be canceled without affecting the main credit card account, making it a valuable security tool. 

Many issuers also provide immediate access to virtual cards upon account approval, allowing users to shop before receiving their physical card. Virtual credit cards function by generating a random 16-digit number linked to a real credit card account. They can be used for online purchases, certain phone transactions, and even in physical stores if added to a digital wallet like Apple Pay or Google Pay. Unlike traditional cards, virtual cards often allow users to set expiration dates and spending limits, giving them greater control over their transactions. Although similar, virtual credit cards are different from digital wallets. 

Digital wallets, such as Apple Pay and Google Pay, store actual card details and other digital assets, while virtual cards generate new numbers for each transaction, offering more protection against cyber threats. However, virtual cards do have limitations—they may not be accepted at all physical locations and can pose challenges for hotel or rental car bookings that require a physical card. Additionally, not all credit card issuers offer virtual cards. To obtain a virtual credit card, users should check if their issuer provides this feature. 

Some banks, like Capital One and Citi, offer virtual card numbers through browser extensions or account portals. Others, such as Chase and Wells Fargo, do not provide one-time-use virtual cards but allow integration with digital wallets. Once generated, users can adjust settings like spending limits and expiration dates to enhance security. While virtual credit cards add an extra layer of protection, they are not entirely foolproof. Hackers may still access an active virtual card, but most issuers provide fraud protection, ensuring users aren’t liable for unauthorized transactions. 

If compromised, a virtual card can be canceled and replaced without changing the main account number. To further enhance online security, consumers can use digital wallets, secure payment platforms like PayPal, and avoid storing payment details in web browsers. Using strong passwords, shopping only on secure networks, and enabling multi-factor authentication also help prevent fraud. 

For those interested in a virtual credit card, the process is simple—choose a card that offers this feature, apply through the issuer’s secure site, and access a virtual number upon approval. By integrating virtual credit cards into their payment methods, users can enjoy safer and more controlled online transactions.

The Hunt for the FTX Thieves Has Started

 

Cryptocurrency has always provided an interesting mix of temptations and difficulties for those trying to steal it.  It is a lucrative target because it is digital cash held in multibillion-dollar sums on hackable, internet-connected networks. However, once stolen, the blockchains on which almost every cryptocurrency is built allow for tracking the money's every move and, in many cases, identifying the thieves.  

Recently, unknown transactions were reported to have drained FTX wallets. As per observers, FTX was hacked or insiders stole client funds during the abrupt FTX collapse. There have been "unauthorized transactions" from the group's wallets to addresses not controlled by FTX, according to FTX US general counsel Ryne Miller. FTX filed for Chapter 11 bankruptcy protection from its creditors yesterday. These creditors are concerned that some of their funds will be unavailable for payment.

On Twitter, a developer announced that "hundreds of millions of dollars" in cryptocurrency were being transferred from FTX wallets. Because of the late hour of the transactions, it appeared that liquidators were not assisting creditors.

Afterward, on-chain forensics expert ZachXBT tweeted that the receiving addresses were not FTX wallets, according to former FTX employees. Because FTX and FTX US are supposedly separate businesses and were operated as such, a hacker would be unlikely to gain simultaneous access to the private keys of both exchanges unless they had inside information or were insiders.

However, given FTX's demise, anything is possible. According to Bloomberg, junior employees took the initiative to sell off some of FTX's troubled assets. There are two major drainage areas that have been identified. It is possible that up to $383 million in cryptocurrency was stolen:
Main draining address: 
https://etherscan.io/address/0x59abf3837fa962d6853b4cc0a19513aa031fd32b

Shitcoin draining address:
https://etherscan.io/address/0xd8019a114e86ad41d71a3eeb6620b19dd166a969

According to Nansen, a crypto analytics research firm, the outflows totaled at least $266 million. As per the Australian Financial Review, the number of missing funds in Ethereum, Solana, BNB LINK, AVAX, and MATIC could be as high as $600 million.

Were the FTX app and website also compromised?

There are also unconfirmed reports that the FTX app has been infected with malware and should no longer be used, as well as the FTX website. However, Rey, an FTX Telegram administrator, uploaded it.

Nevertheless, the puzzling scenario for the 1,2 million FTX customers is still evolving. The FTX app has been updated, but for the time being, experts recommend all FTX clients avoid running the update or interacting with their FTX account.

Customers are advised not to make any changes to their accounts until further information, presumably in the form of an official announcement from FTX, becomes available. According to his most recent tweet, Binance founder and CEO Changpeng Zhao (CZ) is unimpressed with the latest turn of events. Elon Musk also contributed, despite the fact that he was expected to be preoccupied with the blue tick scandal.
