Corvus: Ransomware Attacks Fall
April 14, 2022
The Corvus Risk Insights Index is a compilation of industry trends and data
analysis based on the company’s proprietary IT security scanning technology, the
Corvus Scan, in addition to results from its Policyholder Cybersecurity
Benchmarking Survey, sent to current Cyber and Technology Errors & Omissions
(Tech E&O) policyholders.
“In support of our mission to make the world a safer place, it is our hope that
this report provides guidance not only for our policyholders, but all of those
seeking to protect their business, employees, and customers from cyber threats,
especially at this critical time in history,” said Jason Rebholz, Chief
Information Security Officer at Corvus Insurance. “Corvus’s real-time data and
AI-powered risk management tools provide unparalleled transparency between our
risk capital partners, policyholders, and brokers and allow us to share these
actionable insights to increase awareness around the current state of cyber risk
to help keep everyone safe.”
In the second edition of the Corvus Risk Insights Index, Corvus’s experts —
including data scientists, underwriters, cybersecurity professionals, and claims
managers — reflect on the past year, current trends, and what’s to come in the
remainder of 2022. In reviewing the evolving cyber risk landscape, the report
includes a breakdown of the impact of zero-days and third-party risk, updates on
ransom severity, and a review of recent key vulnerabilities. To shed light on
concerns and perspectives that are unique to the small- and medium-sized
business (SMB) segment, the report also features insights from Corvus’s first
Policyholder Cybersecurity Benchmarking Survey, which captured insights from
their Cyber and Tech E&O policyholders.
Ransomware claims, costs, and
severity
One of the best
indicators of overall cybercrime activity is the rate of
ransomware claims in the Corvus book of business. Based on
Corvus’s claims data, after all of the dire headlines
throughout 2021 the end of the year presented signs of
improvement:
-
In Q4, the rate of
ransomware claims
reached just half of the peak seen in Q1 2021 —
decreasing from 0.6% to 0.3%.
-
While the Q3 2021
average ransom paid was atypically high, the entire 2021
ransoms paid by quarter average was ~$167k, 44.2% less
than the Q3 figure.
-
Overall, fewer
ransoms are being paid compared to those demanded. The
percentage for the last quarter of 2021 held steady in
the low twenties, down significantly from figures that
once were over 50%. As recently as Q3 2020, the ratio
was 44%.
This decrease in cost and
severity can be partially attributed to underwriting
entities requiring stronger backups for insurance coverage,
which is helping to drive the broader trend toward more
sophisticated and resilient approaches to mitigating
ransomware risk.
The data also revealed spikes
in claims tied to major cybercrime events including the
Microsoft Exchange Server vulnerability and the Kaseya
ransomware attack. While these events were enough to
significantly, but temporarily, impact the month-by-month
ransomware claims rate, the overall average severity of
claims declined.
As the cyber threat landscape
continues to evolve, Corvus’s Risk Insights Index™ touched
on Russia's ongoing invasion of Ukraine, which has included
a hybrid warfare model involving cyber attacks against
public and private sector organizations. While attacks have
led to increased concerns over potential collateral damage,
Corvus observed a 30% reduction in ransomware claims
frequency from Q4 2021 to Q1 2022 (through March 15),
highlighting the fractured ransomware threat ecosystem
during a time of war.
Severity is lowered, but not
across the board
The overall severity of
ransomware costs by industry shifted significantly over the
past year. The report indicates a decreasing cost impact on
education and social services, while the professional
services industry (including but not limited to law firms,
consulting firms, and architecture firms) experienced
increased ransomware costs. The data highlights that:
-
The average claim
reached nearly $400,000 within the professional services
industry in Q4 2021, by far the highest in that
timeframe.
-
Healthcare, which saw
an alarmingly high average in claim severity to start
the year, has returned to a historically low average,
with zero ransomware claims recorded in Q4 2021.
The decreasing claims
severity within healthcare may be tied to dissipating public
fears and subsequent exploitation by threat actors during
the height of the COVID-19 pandemic.
SMBs still playing cyber
strategy catch up
Corvus’s first Policyholder
Cybersecurity Benchmarking Survey, conducted in Q4 2021,
showed that SMBs are still building their cyber investments.
The survey was deployed to Corvus’s Cyber and Tech E&O
policyholders, with the nearly 300 respondents’ titles
ranging from C-suite to Vice Presidents, Directors, and IT
Managers. Participants’ company size ranged from fewer than
50 employees to over 250. The results showed that SMBs are
primarily concerned with external threats — attack vectors
including ransomware and phishing — and revealed:
-
Only 8% of the
smallest businesses (with <50 employees) have a
dedicated cybersecurity budget.
-
Among the largest
businesses within the surveyed group — those with 250 or
more employees — 18% reported having a dedicated
cybersecurity budget.
-
Spend on
cybersecurity is expected to increase. Sixty percent of
participants stated that their security spending is
expected to increase with support from their CEO and
senior management.
-
Of the participants
who stated that they need help with security
improvements, 72% were companies that lacked a CISO —
reinforcing the idea that a CISO can play a large part
in improving security posture.
Survey respondents
highlighted a lack of resources and the overall complexity
of security as key driving factors currently preventing
improvements in their defenses. Smaller companies (<50
employees) are more concerned with staying current on new
threats, while larger organizations are more concerned with
vendor breaches, bringing to light the fact that many
companies may fail to emphasize and act on the need for an
internal security culture.
“We are in the midst of a
critical and challenging time for security professionals,”
said Phil Edmundson, Founder and CEO of Corvus Insurance.
“As the security landscape shifts and threat actors continue
to evolve their attacks, this report provides the
data-driven analysis critical for organizations to navigate
and prepare for adverse events in this new cyber age.”
