> AcrossProtocol linked the compromise to a social-engineering attack targeting its registrar, Namecheap. Cloudflare and SEAL911 helped block a phishing site.

AcrossProtocol’s website remains offline after a social-engineering attack gave an unauthorized party control of its domain, disrupting access to the decentralized finance protocol and prompting warnings for users.

AcrossProtocol attributed the compromise to an attack targeting its domain registrar, Namecheap. The team shut down the website within minutes after unauthorized access was established, aiming to limit further damage while it secures the domain and investigates.

Cloudflare and SEAL911 assisted by flagging the domain as at risk and blocking a phishing site. The app remains unavailable during the response, and users were advised to avoid accessing it until further notice.

People affected by the phishing incident were also urged to revoke permissions granted to suspicious integrations. That measure removes access users previously granted to those integrations.

AcrossProtocol facilitates transactions across blockchain networks. A domain registrar manages the website address users rely on to reach a service, so the shutdown has left the platform’s web entry point unavailable as the security response continues.
