Attacks Grew 31% YOY With a Staggering 44,000
Each Day Fueled by World Events
NETSCOUT SYSTEMS, INC., (NASDAQ: NTCT) today announced findings
from its 1H2023 DDoS Threat Intelligence Report. Cybercriminals
launched approximately 7.9 million Distributed Denial of Service
(DDoS) attacks in the first half of 2023, representing a 31%
year-over-year increase.
Global events like the Russia-Ukraine war and NATO bids have
driven recent DDoS attack growth. Finland was targeted by
pro-Russian hacktivists in 2022 during its bid to join NATO. Turkey
and Hungary were targeted with DDoS attacks for opposing Finland's
bid. In 2023, Sweden experienced a similar onslaught around its
NATO bid, culminating with a 500 Gbps DDoS attack in May. Overall,
ideologically motivated DDoS attacks have targeted the United
States, Ukraine, Finland, Sweden, Russia, and multiple other
countries.
During 2H2022, NETSCOUT documented a trend in DDoS attacks
against wireless telecommunications providers that incurred a 79%
increase globally. That trend continued among APAC wireless
providers in 1H2023 with a 294% increase, which correlates to many
broadband gaming users shifting their activity to 5G fixed wireless
access as providers roll out their networks.
NETSCOUT’s insights into the threat landscape come from its
ATLAS sensor network built over decades of working with hundreds of
Internet Service Providers globally, gleaning trends from an
average of 424 Tbps of internet peering traffic, an increase of
5.7% over 2022. The company has observed nearly 500% growth in
HTTP/S application layer attacks since 2019 and 17% growth in DNS
reflection/amplification volumes during the first half of 2023.
“While world events and 5G network expansion have driven an
increase in DDoS attacks, adversaries continue to evolve their
approach to be more dynamic by taking advantage of bespoke
infrastructure such as bulletproof hosts or proxy networks to
launch attacks,” stated Richard Hummel, senior threat intelligence
lead, NETSCOUT. “The lifecycle of DDoS attack vectors reveals the
persistence of adversaries to find and weaponize new methods of
attack, while DNS water torture and carpet-bombing attacks have
become more prevalent.”
Other key findings from the NETSCOUT 1H2023 DDoS Threat
Intelligence Report include:
- Carpet-Bombing Attacks Rise. A resurgence in
carpet-bombing attacks occurred since the beginning of the year,
with a 55% increase to more than 724 daily, which NETSCOUT believes
is a conservative estimate. These attacks cause significant harm
across the global internet, spreading to hundreds and even
thousands of hosts simultaneously. This tactic often avoids
triggering high bandwidth threshold alerts to begin timely DDoS
attack mitigation.
- DNS Water-Torture Attacks Become Commonplace. DNS
water-torture attacks rose nearly 353% in daily attacks since the
beginning of the year. The top five industries targeted include
wired telecom, wireless telecom, data processing hosting,
electronic shopping and mail-order companies, and insurance
agencies and brokerages.
- Higher Education and Governments Disproportionately
Attacked. Adversaries create their own or use different types
of abusable infrastructure as platforms to launch attacks. For
example, open proxies were consistently leveraged in HTTP/S
application-layer DDoS attacks against targets in the higher
education and national government sectors. Meanwhile, DDoS botnets
featured frequently in attacks against state and local
governments.
- DDoS Sources Are Persistent. A relatively small number
of nodes are involved in a disproportionate number of DDoS attacks,
with an average IP address churn rate of only 10%, as attackers
tend to re-use abusable infrastructures. While these nodes are
persistent, the impact fluctuates as adversaries rotate through
different lists of abusable infrastructure every few days.
