Source: hit with a DDoS attack

Earlier this month, VoIP provider suffered a catastrophic week-long DDoS attack that took down almost all of their services and portals, leaving their customers without voice services.

The attack was an extortion DDoS attack where threat actors impersonating the ransomware group ‘REvil’ initially demanded one bitcoin ($45,000) to halt their attacks but later increased it to 100 bitcoins ($4.5 million).

Locally consumer and business  telephone interruption reports are growing in number. A survey of internet postings indicates that the problem seems to be spreading to all of the VOIP providers and is not under control at the present time. Outages are also occurring in Europe and the U.K.
