Odaily News: The Finance Committee of the French National Assembly has passed an amendment that would require the declaration of self-custodial wallet crypto assets valued at or above €100,000 (approximately $112,000) at year-end, with non-declarers facing fines of up to €10,000 (approximately $11,000). The rule has not yet become law and may still be subject to changes.Harry Halpin, CEO of privacy infrastructure company Nym, stated that French tax authorities are suspected of selling taxpayer data to criminals, and the new declaration requirement could threaten the safety of asset holders. Rand Hindi, founder of privacy protocol Zama, called on French crypto asset holders to leave France, and those unable to leave should hire security for their families.The proposal comes amid a series of crypto-related robberies, kidnappings, and "wrench attacks" that have occurred in France in recent years.

Odaily News: According to Ledger monitoring, its security team Ledger Donjon is investigating Ledger signing devices (signers) sold by Southeast Asian distributor CryptoBilis. The batch of devices was implanted with unauthorized hardware components, and Ledger confirmed on October 10 that one user's device was affected. Ledger Donjon's analysis shows that the implant is located inside the device casing and can read the screen display contents, decode the 24-word recovery seed phrase during initial setup, and transmit it externally via a built-in eSIM and LTE. The component does not modify the secure chip, system, or transaction signing. Currently, all confirmed fund losses related to the incident disclosed on October 9 involve devices sold through CryptoBilis. CryptoBilis has stopped selling Ledger devices.
