A total of 23,095 DDoS attacks were carried out on web resources located in 76 countries in the first quarter of 2015, up 15 per cent from the 66 countries affected in the final quarter of last year.
This is one of the findings of a new study by Kaspersky Lab into the botnet-assisted DDoS attack landscape. But although the geography is expanding the overall number of botnet-assisted attacks is down by 11 per cent and the number of unique victims down by eight per cent.
Servers in the US, Canada and China are targeted most frequently. The study also finds that the greatest number of attacks on a single web resource in Q1 2015 was 21, compared to 16 in Q4 2014, and the most prolonged botnet attack occurred for almost six days.
Our CTO Mark Kedgley comments: “DDOS remains one of the most difficult attacks to defend against - by definition, the attack is perpetrated simultaneously from large numbers of devices including home and business users wherever a Trojan has been deployed. This makes the standard countermeasure for DDOS - blocking/blacklisting associated IP addresses - extremely hard.
“Indeed, defending against DDOS is, by the very nature of public-internet-based services, a tough job. One route for mitigation is to better prevent the establishment of Botnets in the first place – this requires a more malware-aware public with better computer-hygiene standards.”
