DDoS Attacks Less Frequent But Pack More Punch

According to the security company’s latest threat intelligence report, the number of large DDoS attacks jumped from 7 to 47 year-over-year in the first half of 2018, and the average DDoS attack size grow 174% during that period. The overall frequency of attacks, however, went down 13%. The overall assault size was driven by novel techniques and has seen an increase of 37% since memcached appeared (memcached amplification fueled a 1.7 Tbps attack earlier this year). Between March and June 2018, the number of vulnerable (and accessible) memcached servers dropped from 17,000 to 550. Denial of service hacking Although it has been used for reflection/amplification for years, Simple Service Discovery Protocol (SSDP) has received increased attention this year, when it was used to deliver traffic from ephemeral source ports. There are around 33,000 SSDP reflectors that could be abused in attacks, the report reveals (PDF). The rise of Internet of Things (IoT) devices, most of which lac

What is a DDoS Attack?

A Distributed Denial of Service (DDoS) attack is an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources. They target a wide variety of important resources, from banks to news websites, and present a major challenge to making sure people can publish and access important information. What happens during a ddos attack ? The Digital Attack Map displays global DDoS activity on any given day. Attacks are displayed as dotted lines, scaled to size, and placed according to the source and destination countries of the attack traffic when known. Some features include: Use the histogram at the bottom of the map to explore historical data. Select a country to view DDoS activity to or from that country. Use the color option to view attacks by class, duration, or source/destination port. Use the news section to find online reports of attack activity from a specified time.
