Rabobank and ABN Amro were targeted by DDoS attacks on Thursday night and Friday morning. As a result their online and mobile banking, iDeal payments and websites were hard to reach or completely offline for several hours.
The attacks on Rabobank started around 6:00 p.m. on Thursday, NOS reports. The problems were resolved shortly before midnight. ABN Amro was attacked during the early hours of Friday morning.
In a DDoS attack a website is bombarded by large amounts of data, crashing its server and therefore also the site.
