Cyberattacks hit ABN Amro's website

ABN Amro Group NV's website came under "significant" cyberattacks May 24, the second attacks of such scale at the bank since the start of 2018, the Dutch banking group told S&P Global Market Intelligence.

The lender said the so-called distributed denial of service, or DDoS, attacks caused its website to slow down and become unavailable during parts of the afternoon and evening May 24, affecting its internet and mobile banking and iDeal payments services.

DDoS attacks overload the server as perpetrators send large volume of data traffic to a website. "A DDoS attack is something different from a hack," ABN Amro said. "At no point is or was the security of internet banking, mobile banking and iDeal under threat."

The bank said mitigating measures have been taken and the bank's website is up and running again, adding that it is "hard to say" how many clients were affected although only those who use its internet banking system were impacted.

ABN Amro's website was last hit by a significant DDoS attack in late January, the bank said, adding that DDoS attacks hit the bank and other Dutch institutions "quite regularly, sometimes even daily."
