NETSCOUT SYSTEMS, INC., a provider of performance management, cybersecurity, and DDoS protection solutions announced findings from its 5th Anniversary DDoS Threat Intelligence Report that points to a new era of multi-vector attacks focused on taking down victims using application-layer and botnet-based direct-path attacks.
Attack frequency has increased tenfold since NETSCOUT’s first report in 2005.
HTTP/HTTPS application-layer attacks
With over one billion websites worldwide, HTTP/HTTPS application-layer attacks have increased by 487 percent since 2019, with the most significant surge in the second half of 2022.
Much of the increase comes from the pro-Russian group Killnet and others that explicitly target websites. Attacks of this nature preceded the Ukraine invasion, knocking out critical financial, government, and media sites.
Addressing the DDoS threat landscape
DDoS attacks threaten organizations worldwide and challenge their ability to deliver critical services"
“DDoS attacks threaten organizations worldwide and challenge their ability to deliver critical services,” said Richard Hummel, Threat Intelligence Lead at NETSCOUT.
Richard Hummel adds, “With multi-terabit-per-second attacks now commonplace, and bad actors’ arsenals continuing to grow in sophistication and complexity, organizations need a strategy that can quickly adapt to the dynamic nature of the DDoS threat landscape.”
Additional findings
Additional highlights from NETSCOUT’s findings include:
- Peak DDoS alert traffic in a single day reached as high as 436 petabits and more than 75 trillion packets. Service providers rigorously scrubbed a large percentage of this traffic, while enterprises eliminated an additional daily aggregate average of 345 terabytes of unwanted traffic.
- Direct-path attacks have increased by 18 percent over the past three years, while traditional reflection/amplification attacks decreased by nearly the same, highlighting the need for a hybrid defense approach to weather the fluctuating attack methodology.
- The U.S. national security sector experienced a massive 16,815 percent increase in attacks related to the pro-Russia Killnet group, including a spike in attacks after President Biden’s public remarks at the G7 Summit and another spike the same day the French and U.S. presidents re-affirmed their support for Ukraine.
- NETSCOUT ASERT analysts tracked over 1.35 million bots from malware families like Mirai, Meris, and Dvinis in 2022, with enterprises receiving over 350,000 security-related alerts with botnet involvement. By contrast, service providers received approximately 60,000 alerts where bots were present.
- Carpet-bombing attacks, a technique that simultaneously targets entire IP address ranges, increased by 110 percent from the first to the second half of 2022, with most attacks against ISP networks.
- A barrage of DDoS attacks hammered EMEA’s optical instrument and lens manufacturing sector, resulting in a 14,137 percent increase, mainly against one major distributor with over 6,000 attacks over four months.
- DDoS attacks on the wireless telecommunications industry have grown 79 percent since 2020, primarily due to the increase in 5G wireless to the home. It accounts for 20 percent of all DDoS attacks for a specific industry, second only to wired telecommunications carriers.
NETSCOUT's DDoS Threat Intelligence Report
ATLAS collects DDoS attack statistics from an average of 93 countries daily
NETSCOUT's DDoS Threat Intelligence Report covers the latest trends and activities in the DDoS threat landscape. It incorporates data from NETSCOUT's ATLAS part of the company’s Visibility Without Borders approach along with expert insights from ASERT, NETSCOUT's security research team.
ATLAS was built over two decades through work with more than 500 Internet Service Providers (ISPs) to create a sensor network that provides visibility into more than 400 Tbps of international transit every second of every day. As a result, ATLAS collects DDoS attack statistics from an average of 93 countries daily, encompassing over 50 percent of the world's internet traffic.
Automatically detect, adapt, and block threat activity
The visibility and insights compiled from the global attack data represented in the DDoS Threat Intelligence Report, and seen in the NETSCOUT Threat Horizon portal, fuel the ATLAS Intelligence Feed (AIF).
In addition, AIF continuously arms NETSCOUT's security portfolio enabling it to automatically detect, adapt, and block threat activity for enterprises and service providers worldwide.
