The Flipper Zero is a compact, open-source device that has gained popularity among security researchers and enthusiasts due to its versatility in emulating various wireless signals.
While it was initially designed for ethical penetration testing and hardware exploration, concerns have been raised about its potential impact on crypto security. Phishing scams often exploit the device's popularity by mimicking sales and requesting payments through cryptocurrencies like Bitcoin or Ethereum.
The device's RFID and NFC features also pose a risk to physical security, particularly when using experimental configurations or NFC-enabled cards for two-factor authentication.
