SignalPlus discloses hack loss under $82K, pledges full user reimbursement

Cointime update: SignalPlus said on Nov. 5 that a cyberattack in the early hours of Nov. 4 caused total losses of less than $82,000, with affected users to be fully reimbursed. The attackers took over a third-party vendor contact’s Telegram account, sent a fake Microsoft Teams meeting invite and infected an engineer’s device to breach the internal network. SignalPlus said it blocked the attack, had partner exchanges disable all associated API keys and paused services for a security review, expecting a phased restoration within days.
