In a phishing attack on Signal's verification services provider, the phone numbers of 1,900 users could have been revealed, according to the company.

Signal said in a blog post that the attacker could also have accessed the SMS verification code used to register with the company.

It released a statement saying, "An attacker could have attempted to re-register number to another device or learned that their number was registered to Signal."

The attack is being investigated by Signal and Twilio Inc which counts over 256,000 businesses among its customers.

Since 2014, Signal has been installed about 58.6 million times globally, according to mobile app analytics firm Sensor Tower.
