Ransomware attacks have become increasingly common in recent years. These cyberattacks involve malware that encrypts an organization’s files and data, rendering them inaccessible. The attackers demand a ransom payment in cryptocurrency in exchange for the decryption key. If organizations don’t pay, they risk permanently losing access to their data. Recovering from a ransomware attack can be a costly and time-consuming process. So how much does it actually cost to remediate a ransomware incident? Let’s take a look at the key factors that contribute to these costs.
Ransom payment
Perhaps the most direct cost of a ransomware attack is any ransom payment made to the attackers. In 2020, the average ransom payment was $154,108. Paying the ransom provides the decryption key to recover files and data. However, it also incentivizes and funds future cybercrime. Many experts advise against paying ransoms.
Business interruption
One of the biggest costs of ransomware stems from business interruption. When systems and files are inaccessible, organizations often have to halt or limit operations. This can mean turning away customers, delaying services, resulting in lost income. For small businesses, just a few days of downtime can be catastrophic. Large enterprises can lose millions per day. Business interruption insurance can help cover these losses.
Emergency response
In the wake of a ransomware attack, expert incident response is required. Consultants are brought in to assess and contain the damage, remove malware from systems, and restore data from backups. This emergency response support does not come cheap. According to IDC, organizations spend an average of $1.1 million on consulting services for a ransomware attack.
Restoring data
If paying the ransom is off the table, restoring encrypted data is a huge undertaking. IT teams must wipe infected systems and restore data from backups. However, backups are often incomplete or outdated. On average, organizations are only able to recover two-thirds of their data from backups. Recreating the lost one-third can be very expensive.
Employee productivity loss
The productivity of employees will plummet in the aftermath of an attack. With systems offline, workers cannot access the tools needed to perform their jobs. Business operations slow or grind to a halt. Depending on the scale and duration of the disruption, these lost productivity hours can significantly impact the bottom line.
Notification costs
Depending on the data compromised, notification and credit monitoring for impacted individuals may be legally required. For example, any breach involving healthcare records in the U.S. must be reported to HHS under HIPAA regulations. These notifications result in costs such as website banners, call center staffing, mail correspondence, and identity protection services.
Fines and legal costs
Regulatory fines are likely if compromised records fall under mandates like HIPAA or GDPR. Failure to secure systems and properly detect the attack could violate standards of due care and due diligence. Affected individuals or shareholder groups may pursue legal action. Fines and legal expenses quickly add up in these situations.
Increased insurance premiums
In the wake of a ransomware attack, annual cyber insurance premiums often rise. Insurers may tag the organization as higher risk. To account for this elevated risk, premiums could increase by 100% or more. Organizations without cyber insurance may struggle to find affordable coverage going forward.
Long-term remediation
The initial emergency response is just the first phase of remediating a ransomware attack. In the weeks and months after, considerable efforts are still needed to fully restore normal operations:
– Ongoing malware removal – Experts must conduct thorough sweeps to ensure all remnants of ransomware are purged from the network.
– Rebuilding servers/endpoints – Infected computers and servers may need to be completely rebuilt or replaced.
– Restoring/recreating lost data – Data recovery is a long, labor-intensive process. Reconstructing custom databases or proprietary information can be especially challenging.
– Hardening security – To prevent repeat attacks, security infrastructure and processes need improvement. Multi-factor authentication, network segmentation, new firewalls/antivirus, and staff training all require investment.
– Documenting the incident – Extensive reporting and documentation is required both internally and for external compliance.
All of these long-term remediation efforts accumulate costs in the months following the attack. They are essential for minimizing damage and preventing future incidents. But they extend the timeline and budget for recovery substantially.
Indirect costs
Some ransomware impacts are difficult to quantify directly. But they nonetheless take a toll on the organization. These include:
– Reputational damage – Data breaches often generate negative media coverage. Ransomware attacks damage brand reputation and public trust.
– Loss of competitive advantage – With operations impaired, competitors may seize the opportunity to lure away customers. This loss of competitive edge has lasting impacts.
– Diminished company valuation – Cyber incidents can drag down the overall market value of an organization. This makes it more difficult to secure loans or investments.
– Partner/supplier disruption – Ransomware can spread through interconnected systems to impact supply chains and business partners. The full business ecosystem suffers.
Though indirect, these consequences all divert resources toward recovery and re-establishing market position. They quickly multiply the overall costs of an attack.
Cost breakdown by industry
The costs to remediate ransomware vary significantly across different industries:
| Industry | Average total cost |
| Healthcare | $7.13 million |
| Energy & utilities | $6.39 million |
| Pharmaceuticals | $5.06 million |
| Education | $4.43 million |
| Retail | $3.11 million |
| Media | $2.8 million |
| Government | $2.46 million |
| Transportation | $2.43 million |
| Communication | $2.07 million |
| Services | $1.82 million |
| Manufacturing | $1.78 million |
Healthcare faces the steepest recovery costs due to regulatory requirements and the severe business interruption when medical systems go offline. Industries like energy, pharmaceuticals, and education also deal with highly sensitive data, which makes the impact of ransomware particularly devastating. Lower-cost industries like manufacturing and services have less data-dependence and can sustain some downtime without catastrophic impact. But recovery expenses still quickly escalate.
Cost factors
Many variables influence the overall ransomware remediation costs:
Scale of infection – Was it contained to a few endpoints or did it compromise the wider network? Larger infections leave more systems to clean up.
Importance of encrypted data – Was it routine data or mission critical information essential for operations? The availability and integrity of the encrypted data affects downtime and recovery complexity.
Timeliness of detection – Early detection can drastically limit damage. Slow detection allows malware to spread farther and encrypt more data.
Ransom amount – Larger ransom demands raise remediation costs. The average ransom request was $170,404 in 2020 but demands over $1 million are becoming more common.
Use of backups – Organizations without reliable, isolated backups lose more data and functionality during recovery.
Compliance requirements – Industries like healthcare and finance have stringent regulations that escalate costs of reporting, notification, fines, and legal liability.
Proactive security measures are the most effective way minimizing ransomware remediation costs. Segmenting networks, training staff on cybersecurity best practices, keeping software patched and updated, and maintaining robust backups are all essential precautions.
Cost mitigation tactics
Along with prevention, organizations can take proactive steps to reduce the potential costs of future ransomware remediation:
– Purchase cyber insurance with ample coverage for income loss, data recovery, and liability.
– Maintain an emergency fund with reserves allocated specifically for cyber incident response.
– Develop a data valuation framework that inventories all systems and rates data criticality.
– Establish business continuity and disaster recovery plans that prepare for scenarios where systems are down.
– Test and upgrade backups regularly to maximize recoverability without paying the ransom.
– Segment networks and implement role-based access controls to limit the spread and impact of infections.
– Maintain contacts with external cybersecurity firms in case expert incident response is needed.
Investing in mitigation upfront reduces long-term costs and disruption. It also enables smarter response when an attack does occur.
Conclusion
Recovering from a ransomware attack comes at a monumental price, with the average total cost of remediation exceeding $1.8 million across all industries. The combination of ransom payments, business interruption, lost productivity, data recovery efforts, reputational harm, and strengthened security easily create seven-figure remediation costs. While paying ransoms is not recommended, even refusing to pay comes at a high price for most organizations.
Healthcare, energy, pharmaceuticals, education, and retail tend to be the sectors most severely impacted by ransomware. The total costs are largely dictated by the importance and volume of encrypted data, the timeliness of detection, and the scale of the infection. To reduce costs, proactive prevention and mitigation tactics are critical, ranging from employee training to maintaining modern backups. In the end, while the exact figures may vary case-by-case, the enormous toll of ransomware attacks is a clear threat to organizations across all industries. Understanding remediation costs is key for justifying stronger cybersecurity strategies and getting leadership buy-in for critical IT security investments.
