Critical Alby Hub Vulnerability Exposed Bitcoin Wallets to Complete Takeover
In September 2026, Bitcoin wallet company Alby disclosed a critical vulnerability in Alby Hub versions v1.7.0 through v1.18.5 that allowed attackers to completely take over internet-exposed Lightning wallets and drain funds. The flaw affected self-hosted Bitcoin wallets where owners had inadvertently exposed their Hub management interfaces to the public internet, often following Alby's own documentation that recommended such configurations. At least one user was confirmed affected, with the company providing limited details about the vulnerability mechanism pending responsible disclosure. The incident highlights the ongoing security challenges in cryptocurrency infrastructure, particularly as Bitcoin adoption accelerates and self-custody solutions become more mainstream. With ransomware groups increasingly targeting cryptocurrency platforms and the rise of state-sponsored attacks on financial infrastructure, vulnerabilities in wallet software present critical risks to both individual users and the broader digital asset ecosystem.
