This year the top motivation wasn’t hacktivism or vandalism, but ‘criminals demonstrating attack capabilities,’ Arbor Networks report claims.

Cyberattacks around the world are growing in size and complexity, according to Arbor Networks 11th Annual Worldwide Infrastructure Security Report, released January 26 by Arbor Networks, the security division of NETSCOUT.

For the first time, nearly half of the respondents were from enterprise, government and educational organizations, with service providers at 52 percent. Healthcare is one of the verticals included in the enterprise category.

The survey garnered 354 responses, up from 287 received last year, from a mix of Tier 1 and Tier 2/3 service providers, hosting, mobile, enterprise and other types of network operators from around the world.

“This report provides broad insight into the issues network operators around the world are grappling with on a daily basis,” Arbor Networks Chief Security Technologist Darren Anstee said in a statement announcing the report. “The findings from this report underscore that technology is only part of the true story since security is a human endeavor and there are skilled adversaries on both sides.”

Arbor Networks lists the top five Distributed Denial of Service trends and also the top five advanced threat trends. DDoS usually involves a system infected with a Trojan: malware designed to give unauthorized access to a user’s computer.

DDoS trends:

Change in attack motivation: This year the top motivation wasn’t hacktivism or vandalism, but ‘criminals demonstrating attack capabilities’ – something typically associated with cyber extortion attempts.

Attack size continues to grow: The largest attack reported was 500 Gbps, with others reporting attacks of 450 Gbps, 425 Gbps and 337 Gbps. In 11 years of the Arbor Networks survey, the largest attack size has grown more than 60X.

Complex attacks on the rise: 56 percent of respondents reported multi-vector attacks that targeted infrastructure, applications and services simultaneously, up from 42 percent last year. Ninety-three percent reported application-layer DDoS attacks. The most common service targeted by application-layer attacks is now DNS (rather than HTTP).

Cloud under attack: Two years ago, 19 percent of respondents saw attacks targeting their cloud-based services. This grew to 29 percent last year and to 33 percent this year. Fifty-one percent of data center operators saw DDoS attacks saturate their Internet connectivity. There was also a sharp increase in data centers seeing outbound attacks from servers within their networks, up to 34 percent from 24 percent last year.

Firewalls continue to fail during DDoS attacks: More than half of enterprise respondents reported a firewall failure as a result of a DDoS attack, up from one-third a year ago. Firewalls add to the attack surface and are prone to becoming the first victims of DDoS attacks, as their capacity to track connections is exhausted. Because they are in line, they can also add network latency.
