SignalPlus fully compensated all 23 users affected by a cyberattack, paying $81,897 within 72 hours of detecting the incident on Nov. 4. The attack originated from a compromised third-party Telegram account and targeted user accounts without configured IP whitelists. SignalPlus notified partner exchanges, suspended relevant API keys, halted services on the affected platform and began a comprehensive security review. It has since raised API access requirements, made IP whitelist verification mandatory and tightened internal device controls. Services will resume gradually after the system upgrade is complete.
