SignalPlus Reimburses 23 Users $81,897 After Nov. 4 Attack

SignalPlus reimbursed 23 users a total of $81,897 within 72 hours of detecting unusual activity Nov. 4, completing a pledge to compensate affected users after the attack.

SignalPlus attributed the attack to a compromised third-party Telegram account. The company said accounts without IP allowlists were affected.

After detecting the activity, SignalPlus notified partner exchanges and pushed to suspend related API keys. It paused affected services, began a security review and contacted affected users to complete verification while investigating the incident.

The platform is raising API access requirements, adding IP allowlist checks and tightening controls on employee devices and internal access. Services are expected to resume gradually after the system review and upgrades are complete.
