AMERSHAM, England, May 11, 2021 /PRNewswire/ -- Corero Network
Security, a leading provider of real-time, high-performance,
automatic Distributed Denial of Service (DDoS) cyber defense
solutions has published the latest edition of its annual DDoS
Threat Intelligence Report that compiles the latest trends,
observations, predictions, and recommendations based on DDoS
attacks against Corero customers during 2020.
The report, now in its 6th year, highlights that DDoS threats
are growing in sophistication, size, and frequency. Yet 2020, also
reveals changes in attacker behaviour during the pandemic including
a year-over-year increase of nearly 400% in the use of OpenVPN
reflections as an attack vector.
As the report co-author Ashley
Stephenson for Corero explains, "OpenVPN as a reflection
DDoS vector is bad news for the victim being attacked but, also for
the organisation whose OpenVPN infrastructure is being used to
launch the attack as their remote workers will suffer from a
degraded, or possibly unusable, service, impacting productivity
and, potentially, business continuity."
The report also finds a 70% growth in DDoS attacks over 10Gbps
as high packet rate attacks grew overall during 2020, compared to
slight declines in 2019. The report suggests it is due to the
increasing shift to 100Gbps Internet connectivity and is
accompanied by a trend indicating more everyday DDoS larger
than for 10G. Frequency of repeat attacks also grew with a 68%
increase of organisations experiencing a second attack within a
week.
However, the report does have some constructive recommendations
regarding DDoS defense. "With a 2020 estimate that 99% of observed
attacks are coming in below link saturation there is a real
opportunity to detect and block many DDoS attacks in real time
without requiring expensive and time-consuming traffic redirection
to cloud solutions," says Ashley, "This means that most attacks can
be addressed by on-premises solutions without the disruption, risk
or cost of re-routing customer traffic across the Internet to third
party scrubbing centers."
Looking towards 2021 and Ashley believes that the data from the
report shows that DDoS attacks and threats are not going away
anytime soon, "Once again we are reporting a net increase in the
number of unique DDoS attack vectors seen in the wild and in the
level of year-over-year DDoS activity," he says, "The specific
example of the mid-year FBI alert regarding the malicious use of
built-in network protocols for DDoS attacks demonstrates that
development of new vectors is inevitable. Yet our data shows that
these exploits were already being used in attacks before the FBI
alert and their use continues to grow to this day. Prevention is an
impractical strategy, detection and mitigation continue to be the
only defense."
As the trend towards short duration, high intensity attacks
using multiple vectors continues, Ashley advises that "…as
organisations plan their strategy for effective DDoS protection,
the relationship between time-to-mitigation and potential downtime
is a vital consideration. Organisations must consider that
the typical time to swing traffic to cloud DDoS protection means
the attack is often already over and the damage may be done."
