Two UK VoIP operators have had their services disrupted over the last couple of days by ongoing, aggressive DDoS attacks.
South Coast-based Voip Unlimited has confirmed it has been slapped with a “colossal ransom demand” after being hit by a sustained and large-scale DDoS attack it believes originated from the Russian cybercriminal gang REvil.
This morning, it confirmed that “services are operational … however the attacks are still ongoing.”
Separately, London-based Voipfone said it is still suffering outages on voice, inbound and outbound calls, and SMS services. It told customers on Tuesday in a status update that it had been hit by “a further DDoS attack” after the initial attack, revealed to customers via email as having taken place over the Monday bank holiday.
