News linked to both this project and an event.
Bitcoin payment processing service BTCPay Server has temporarily restricted public remote connections to Lightning Network nodes running Lightning Network Daemon (LND) software. Attackers exploited a severe vulnerability to obtain credentials and transfer funds. The number of affected operators and the total amount stolen have not yet been disclosed. This restriction affects external wallets such as Zeus that connect via BTCPay Server domains or Tor onion addresses in Docker deployments, but Lightning Network payments can still continue. BTCPay Server stated that remote access functionality will be restored once security is confirmed. BTCPay Server 2.4.2 will install LND 0.21.1 and automatically regenerate macaroon credentials during standard installation. Foundation and Citadel21 have respectively disclosed that funds from their Lightning Network nodes were swept. Foundation stated that hot wallets were not affected, and the specific amounts of losses have not been disclosed.
According to Cointelegraph, Bitcoin Lightning Network self-custodial wallet Zeus Wallet voluntarily took its infrastructure offline following a cybersecurity attack on Wednesday and is currently conducting a comprehensive audit of the system, with services to be restored upon completion. Zeus founder Evan Kaloudis stated that the attack was contained within hours, no customer fund losses were found, and there was no evidence that the Lightning node software was affected; the scope of the incident was limited to Zeus's own infrastructure. For users forced to close LSP channels during this incident, Zeus promised to provide replacement channels after services are restored. The company has not yet disclosed the specific nature of the attack or a timeline for resuming operations. Zeus stated that this incident will further drive its security development on Trusted Execution Environment (TEE) and Validating Lightning Signer (VLS) projects.
