Hass and Associates Cyber Security: Web sites attacks around Australia are shorter but bigger

Posted in , ,
Web sites attackers are utilizing shorter bursts of activity to infiltrate servers and systems inside a large way, in comparison towards the relaxation of Web sites attacks in Asia-Off-shore.

Arbor Networks' first-quarter Active Threat Level Analysis System (ATLAS) set of distributed denial-of-service (Web sites) attacks demonstrated that Australia possessed a shorter time period of Web sites attack activity, however that the attacks were greater in scale, as compared to the relaxation of Asia-Off-shore.

Arbor Systems discovered that the attack length around Australia throughout the very first quarter of 2015 was 22 minutes, versus 46 minutes in Asia-Off-shore. Consequently, nearly all attacks were so short resided that 96 percent survived under 1 hour, in comparison to Asia-Off-shore, where 90 % of attacks survived under an hour or so.

However, the typical size Web sites attacks around Australia were 1.25Gbps roughly two times as large because the average attack recorded in Asia-Off-shore.

"Rapid time period of attacks reported in Q1 is interesting. Short bursts of Web sites attack activity require automated defences to safeguard against them," stated Nick Race, Australia country manager for Arbor Systems.

"Operators around Australia absolutely should be aware. On-premise Web sites protection is important for recognition and minimization of attacks, enabling bad visitors to be scrubbed within an immediate and automatic fashion."

Based on Arbor Systems, attackers utilized reflection amplification techniques on network time protocol, simple service discovery protocol (SSDP), and DNS servers.

Around Australia, SSDP capped their email list for many common individual reflection attack within the first quarter, using the biggest reported at 26Gbps. However the biggest individual attack was an NTP reflection attack which was recorded at 51Gbps.
