Last week, many Internet Service Providers (ISPs) in Belgium, France and the Netherlands reported DDoS attacks targeting their DNS infrastructure.
The list of ISPs attacked in the last week includes the Belgian EDP, the French Bouygues Télécom, the FDN, K-net, SFR, the Dutch Caiway, Delta, FreedomNet, Online.nl, Signet and Tweak.nl.
The attacks did not last more than a day and eventually subsided, but ISPs "fell" while DDoS was active.
NBIP, a non-profit organization set up by Dutch ISPs to collectively fight DDoS attacks and governmental attempts to intercept phone calls, provided ZDNet with additional information about last week's incidents.
"Most of the [attacks] were DNS support and LDAP attacks. "Some of the attacks lasted more than 4 hours and reached 300 Gbit / s in volume," the NBIB said.
DDoS attacks on European ISPs began on August 28, a day after a criminal case was uncovered. gang involved in DDoS blackmail against financial institutions around the world, with victims such as MoneyGram, YesBank India, Worldpay, PayPal, Braintree and Venmo.
While there is still no evidence that the two series of events are related, DDoS attacks against financial services retreated as soon as the attacks on European ISPs began.
In addition, sources monitoring the gang told ZDNet that shortly before attacking financial services, the same group had targeted several ISPs in Southeast Asia a few weeks earlier.
In addition, several security experts have stated that the massive CenturyLink outage over the weekend is believed to have been the result of a DDoS attack. In separate reports, both the Cisco As well as the CloudFlare stated that the interruption was due to a DDoS attack.
