More than a dozen internet service providers (ISPs) across Europe have reported DDoS attacks that targeted their DNS infrastructure.

The list of ISPs that suffered attacks over the past week includes Belgium's EDP, France's Bouygues Télécom, FDN, K-net, SFR, and the Netherlands' Caiway, Delta, FreedomNet, Online.nl, Signet, and Tweak.nl.
Attacks lasted no longer than a day and were all eventually mitigated, but ISP services were down while the DDoS was active.

"Multiple attacks were aimed towards routers and DNS infrastructure of Benelux based ISPs," a spokesperson said. "Most of [the attacks] were DNS amplification and LDAP-type of attacks."

The DDoS attacks against European ISPs all took place starting with August 28, a day after ZDNet exposed a criminal gang engaging in DDoS extortion against financial institutions across the world, with victims like MoneyGram, YesBank India, Worldpay, PayPal, Braintree, and Venmo.

While ZDNet does not yet have any evidence that the two series of incidents are connected, the DDoS attacks against financial services subsided right as the attacks against European ISPs got underway.

Updated (September 4, 2020):

Update on September 4: The Dutch cyber-security agency (NCSC) has published an advisory today confirming that the Dutch ISPs attacked this past week have been the subject for DDoS extortion attempts, with the attackers demanding large sums of money in Bitcoin to stop the attacks — similar to the attacks against financial institutions reported by ZDNet last week. There was no attribution to the attacks, so we still can't confirm it's the same group.
