Ending the ransomware scourge starts with reporting, not blocking cyber-insurance
By Monica Shokrai, head of business risk and insurance, Google Cloud, and Kimberly Goody, cybercrime analysis lead, Google Threat Intelligence Group
Ransomware is wreaking havoc around the world, underscoring the need for better collective defensive action from public and private sector organizations.
Globally, ransomware continues to be a complicated and pernicious threat, according to our M-Trends 2024 report. It accounts for more than 20 percent of cyberattacks, year after year. Ransomware at one U.S. health insurance organization forced the shut down of operations at hospitals and pharmacies for several weeks earlier this year, a move that cost the company an estimated $872 million so far.
Victims of these attacks are often left with the difficult decision to pay a ransom. At least $3.1 billion has been paid in ransom for more than 4,900 ransomware attacks since 2021, wrote Anne Neuberger, U.S. deputy national security adviser for cyber and emerging technology, in October — and these are only the attacks that we know of because they’ve been reported.
Law enforcement and impacted organizations have stepped up their fight against ransomware this year. Some of them have developed a multifaceted approach that combines strategic interventions, technological defenses, and law enforcement efforts to combat it, and so far that’s proven helpful. These efforts led to 14 disruptions by law enforcement in ransomware operations as of September.
Despite these actions, attacks continue. Defending against ransomware is so complicated that even some independent cybersecurity researchers, who had been calling for bans on insurance payments to organizations suffering from ransomware attacks, have backed down from their hard-line positions.
While solutions to the threat are complex, cyber-insurance can play a key role. Cyber-insurers can help reduce attackers’ financial gains from incidents, first and most importantly by requiring a minimum level of security standards to strengthen an organization’s defenses before approving an insurance policy.
Insurers have also been shown to reduce attackers' financial gains by limiting or avoiding ransom payments altogether and advising on best practices, particularly regarding backups. If a ransomware attacker demands a $2 million bounty to restore data, but cyber-insurance can embolden an organization under attack to more confidently assert their counter-demand for a reduced payment, that can help the attacked organization strengthen its position and even pay a lower sum — or none at all.
Cowbell Cyber, a cyber-insurance firm, recently found that ’businesses using Google Cloud report a 28% lower frequency of cyber incidents relative to other cloud users.’
However, some believe that cyber-insurance encourages ransomware payments, and would prefer cyber-insurance coverage for ransomware to be banned. Outright bans on cyber-insurance coverage for ransomware payments are likely to harm small businesses more than large ones. Larger businesses are often better positioned to absorb the financial cost of ransomware payments on their own. Conversely, a ban would hurt smaller businesses in outsized ways.
If the ultimate goal of banning insurers from reimbursing ransomware payments is to reduce the profitability of ransomware attacks, then actions that require victims to report payments have the potential to be more impactful. Mandatory reporting could improve law enforcement tracking efforts and introduce more opportunities to recover funds even after payment is sent.
If larger companies continue to pay the ransom despite insurance not covering it, the impact of a ban on the insurance coverage becomes less meaningful. However, a more effective approach may be to incentivize the adoption of policies that improve the digital resilience of private and public-sector organizations to drive down the risks they face. As Phil and Andy wrote in the previous edition of this newsletter, this often means updating legacy IT.
One approach is to incentivize the adoption of secure by design and secure by default technologies, such as those that we develop at Google Cloud. Cowbell Cyber, a cyber-insurance firm, recently found that "businesses using Google Cloud report a 28% lower frequency of cyber incidents relative to other cloud users.” The report also found that Google Cloud exhibited the lowest severity of cyber incidents compared to other cloud service providers.
At-Bay, another cyber-insurance firm, found customers using Google Workspace experienced, on average, 54% fewer email security incidents.
There is an opportunity with AI, as well, to better scale existing anti-ransomware efforts to meet the needs of defenders. We’ve already begun to see AI have a positive impact by helping organizations grow their threat detection efforts and more efficiently address vulnerabilities before attackers can exploit them.
