Cyber threats: A year in retrospect

What the C-suite and boards need to know and act upon

In its 2021 Year in Retrospect, the 5th annual report, PwC uncovers trends in the cyber threat landscape that every executive in the C-suite and the boardroom must know. 

Much of the workings of cybersecurity — the good and the bad — is invisible to those not in the field, hence the mystique. But with businesses digitally connecting more processes, products and people, cybersecurity risk has risen to the top of the list of CEO worries globally. 

Nearly half of CEOs around the world are “very concerned” or “extremely concerned” about how cyber threats could impact their business. That’s why every CEO and board member should become cyber-savvy. When they better understand the risks they face, own and govern, they can direct resources and organizational will towards mitigating those risks.

Our analysis in this report is based on intelligence gleaned from PwC’s incident response engagements and our managed security operations services around the world. It’s founded on in-house intelligence on cyber attacks and a wide variety of threat actors. Our research delves into the motivations and techniques of major threat actors globally, who seek to steal intellectual property, disrupt critical infrastructure, commit financial crimes, as well as obtain access to government networks.

Four cyber threat trends that CEOs, boards and C-suite executives need to know and act upon

1. Ransomware dominated the headlines throughout 2021, as the data of 2,435 ransomware victims were exposed on leak sites, almost double the 1,300 victims in 2020. Threats multiplied, their sophistication increased, and ransom demands climbed.

Why?

Scalability. Ransomware operations now run as businesses, with the main operator entering agreements with affiliates to “lease” the ransomware.

Fewer skills required. Attackers can rely on an established cybercrime ecosystem servicing ransomware operations but independent of them, including access-as-a-service operations and credentials marketplaces.

Profitability. High-profile ransomware attacks in 2021 have seen victim organizations paying seven-figure ransoms. 

Takeaways

For boards

Acting quickly can prevent widespread impact. Conduct regular crisis simulations, from the board level down to security operations, so everyone can have a chance to rehearse what to do if ransomware strikes. 

For the CRO/Business heads

CFO - Review your cyber insurance plan. Will it be adequate to cover potential costs for ransomware payment and recovery? Do you need to consider alternatives? How would a ransomware incident impact revenues and financial reporting? What is your responsibility for investor disclosure if there was a material impact?

Business heads - Review your business continuity plans to ensure critical business services are not disrupted if your mission-critical digital assets are compromised.

For the CIO/CISO

Implement an intel-led approach to hygiene and threat detection to track known ransomware threat actors and their tools and methods and stop them. 

Build partnerships with national and local government agencies tasked with cyber defense. Be prepared to share information. Truly understanding and planning the response to a major attack is like putting together puzzle pieces — 90% of which are in the hands of private companies.

2. Supply chain compromises became commonplace in 2021. Attacks took several forms: software attacks, digital trust compromises, abuse of trusted infrastructure and third-party access.

Why?

Supply chain attacks have long been used by multiple threat actors. While they’re traditionally associated with state-sponsored threat actors, financially motivated threat actors have become very successful in exploiting them.

Takeaways

For boards

You’re less in control of your perimeter than you were a year ago, and will likely be even less in a year's time. Criminals, not just nation-states, are exploiting this. What steps is management taking to implement Zero Trust principles? (The Zero Trust security model assumes that your systems have already been breached. This requires evolving the security mindset and controls from the traditional philosophy of “trust, but verify” approach to “never trust, always verify.”)

Consider consolidating your tech vendors/supply chain to reduce complexity. Asking management their plans for uncovering the large blind spot hiding the risks in your business relationships can be helpful.

For the CRO/Business heads

CRO / COO - Understand your third-party relationships and get regular updates on the risks posed by interactions with them and their connectivity to your organization.

COO - Update and rehearse response plans to include supply chain compromise scenarios. 

CDO - Strengthen your data trust processes. Data is the target for most attacks on the supply chain. Data trust and good third-party risk management go hand in hand.

For the CIO/CISO

Build defense in depth to prevent, detect and block threats that might begin inside your network or have access from a third party supplier.

Collaborate closely with your third parties and build approaches for exchanging threat intelligence to secure your collective digital ecosystem.

3. Discovery and disclosure of 0-day vulnerabilities — software bugs newly discovered by researchers — rose in 2021. These 0-days can be exploited for cyber attacks before the developer has a chance to make a fix (patch, in cyber parlance).

Why?

In 2021, vulnerability researchers saw the rise of more ways —both legitimate and criminal — to earn financial reward for their exploit development work. 

Aside from researchers, criminal exploit brokers and private espionage companies are important players in the exploitation of 0-days. These actors aim to exploit these vulnerabilities before the software vendors can distribute patches and advisories.

Also, 0-days were used prominently for national security purposes in 2021, what is called “0-day diplomacy.”

Takeaways

For boards

Speed is important when responding to 0-day vulnerabilities. Ask your management how they are improving their processes to shorten the time from discovery to remediation of 0-day vulnerability. Ask how they decide on prioritization of mission-critical assets.

For the CRO/Business heads

Are you aware of your mission-critical digital assets and how would you prioritize them for remediation?

Understand what would be needed to appropriately report the vulnerabilities that could make your digital products and services vulnerable to 0-day bugs.

For the CIO/CISO

Accuracy and quality of your asset inventory is critical. Improve your ability to quickly identify assets impacted by 0-day vulnerability through ongoing improvements to the asset discovery and inventory processes.

Shorten the time from discovery to remediation of 0-day vulnerability through ongoing focus on automation and optimization of the emergency patch management process.

Refine your threat hunting capabilities to spot potential 0-days within your environment and define an approach for responsible disclosure.

4. Cyber attacks-at-scale flared up in 2021, as quartermasters flourished.

Why?

Quartermasters have been traditionally associated with supplying to military units. In the past, most of the sophisticated tools were accessible to select threat actors only, or obtained via a central entity in charge of distributing them and enabling their use. 

Enter the commercial quartermasters: private companies that sell offensive security solutions such as spyware, 0-day exploits and related capabilities to entities. These are global operations: Customers of commercial quartermasters might be based in several, possibly mutually hostile, countries. They lower the barriers to entry, since cybercriminals and nation-state actors no longer need to develop their own malware. They can specialize instead in spreading it throughout the target’s IT environment or deploying leased ransomware at scale across multiple targets. Commercial quartermasters drew attention in 2021 for zero-click spyware installed on smartphones of civilian targets.

Takeaways

For boards

Failure to adapt is failure. Ask your CISO about approaches they’re taking to keep pace with new and unknown threats and how they can educate you.

Ask your CISO also about how they’re updating threat assessment continually for your organization to account for the increased open-source and commercial off-the-shelf (COTS) offensive security tools.

For the CRO/Business heads

Update your enterprise cyber risk assessment to account for the latest offensive security tools.

Determine if the changes in cyber risks will be sufficiently covered by your cyber insurance.

For the CIO/CISO

Implement defense in depth. Organizations shouldn’t rely on any one tool or security layer detecting or blocking 100% of all attacks. Layered security increases the probability that you will block or detect activity and gives you more information for responding to incidents.

To address the increasing scale of attacks, implement intelligence- and automation-driven approaches for detecting and responding to potential threats.

Looking to 2022: Cloud breaches are a top concern

Business executives don’t expect cyber threat activity to recede this year. More than half of 3,600 respondents to our 2022 Global Digital Trust Insights survey expect an increase in reportable incidents, with attacks on the cloud services at the top of the list.

Attacks on cloud services are especially concerning as the pandemic has accelerated cloud adoption worldwide. For two years in a row, cloud security has been the top priority for cyber investments, according to more than 3,000 business executives who have responded to our Global Digital Trust Insights surveys. And rightfully so. An overwhelming majority of cyber attacks in the past 18 months happened in the cloud, and nearly all could have been avoided had security been ready at the outset.

Takeaways

For boards

Traditional security approaches are not fit for multicloud environments. 

Aside from oversight on the cloud strategy, ask management how they are evolving the security framework for multicloud and hybrid cloud environments.

Conduct crisis simulation, from board level down to IT practitioners, to help prepare the entire organization and ensure everyone knows what to do if there is a cloud breach.

For the CRO/Business heads

CRO - Enhance the risk and controls framework to factor in the security challenges and opportunities presented by cloud.

Business heads - Understand how a cloud breach could impact your critical business services and mission-critical assets, and rehearse your business continuity plans for those scenarios.

For the CIO/CISO

Cloud service providers are implementing continuous updates to their systems and rolling out new offerings faster than most companies can keep track of them. Put controls in place to monitor new cloud functions and make sure those updates don’t jeopardize your organization's security posture and/or regulatory obligations.

Educate your digital, IT infrastructure and developer teams on cloud security, and work with them to embed security and privacy requirements into digital transformation programs and DevOps processes. 

Encode security policies and controls into the very fabric of your cloud environment. Security-as-code includes automation to keep the information and operations secure in your various environments, no matter what changes.

Bottom line

CEOs, worried about cybersecurity risks, can do much to increase the resiliency of their organization. Chief executives at companies that had the best cybersecurity outcomes over the past two years are 14 times more likely to provide significant and broad support to cybersecurity, according to our analysis. Cybersecurity is the ultimate team sport — every C-suite executive has a role. 

Among the top six concerns of CEOs, cyber-insecurity is the one most associated with inability to innovate. Cyber-insecurity threatens companies' future. But acting on the recommendations here, CEOs can be more confident of cyber for the upside of their business: They can pursue ambitious digital transformation goals while continuing to earn customer trust.
