A massive DDoS attack on key DNS infrastructure happened last Friday. It appears that one of Singapore’s telco – Starhub – was also under attacked on Saturday and Monday. There was no further information whether it is from the same attackers or whether it was a copycat attack.
The company said it analysed network logs of the disruptions and found that it had experienced intentional and likely malicious distributed denial-of-service (DDoS) attacks on its domain name servers (DNS).
