Distributed denial of service

DDoS attack against CANTV links targeting a PDVSA IP address (December 2016)

On December 2, 2016, a denial-of-service attack was recorded against CANTV’s international links, targeting the IP address 200.11.137.56 assigned to PDVSA. LANautilus/Telecom Italia reported the attack, and Digital Attack Map recorded a peak of 5,559 Mbps for about six minutes. The CrediCard outage occurred on the same day and was reported by authorities as an attack on the banking sector, but sources at CANTV indicated that the interbank network was separate from the internet and that the two events should not be treated as a single technical incident.

Impact details

It has been confirmed that DDoS/DoS traffic overwhelmed CANTV’s international links and targeted a PDVSA IP address, causing slowdowns and degradation of Internet service. The CrediCard service outage, which occurred on the same day, affected payment services; however, it has not been considered a confirmed technical impact of this DDoS attack, as CANTV sources have distinguished between the two events.
