The final quarter of 2025 is delivering what the data predicted all year: ransomware attacks hit 9,251 recorded incidents through November, a 45 percent increase from 2024 and the highest volume on record. For small and mid-size business owners, the headline statistic matters less than what it reveals about how attacks are changing and who is being targeted.
The Numbers Behind 2025’s Ransomware Record
Cybersecurity Ventures places global ransomware damage costs at $57 billion annually in 2025, translating to roughly $156 million per day. That figure includes ransom payments, downtime losses, data restoration costs, legal fees, and reputational damage. The ransom itself represents a fraction — the average demand for an SMB incident is $84,000. The average total recovery cost exceeds $500,000.
The IBM Cost of a Data Breach Report 2025 calculates the average cost of a ransomware-specific incident at $4.4 million across all organization sizes. For small businesses, recovery frequently follows one of two paths: organizations that absorbed significant financial damage but survived, and those that didn’t. Sixty percent of small businesses hit by a major cyberattack close within six months. One in five that experience an attack go bankrupt, according to a Mastercard survey of 5,000 SMB owners.
The 45 percent increase in attack volume between 2024 and 2025 reflects two trends converging: the rise of Ransomware-as-a-Service platforms that allow low-skill attackers to execute sophisticated campaigns, and a deliberate strategic shift toward targeting organizations with weaker defenses. Small and mid-size businesses now absorb 88 percent of ransomware incidents — not because attackers hate small businesses, but because they represent the path of least resistance to guaranteed revenue.
What Changed in 2025: Attack Methods and Entry Points
The annual shift in attack methods matters as much as the volume increase. In 2025, 32 percent of ransomware attacks entered through exploited vulnerabilities in software — meaning unpatched systems, not phishing emails. Twenty-three percent entered through compromised credentials, and 18 percent through phishing. The remainder used a mix of supply chain compromises, exposed remote access systems, and social engineering.
What this distribution tells business owners is that no single defense closes all entry points. A business that has excellent email filtering but hasn’t patched its operating systems in three months is still exposed. A business with strong passwords but no multi-factor authentication on its remote access systems is still accessible. The attack surface has expanded, and attackers are methodically searching all of it.
Double extortion — the practice of encrypting data and simultaneously threatening to publish it — was present in 87 percent of 2025 attacks, according to ransomware analysis from Huntress. This means paying the ransom no longer guarantees data stays private. Sixty-three percent of victims who experienced double extortion refused to pay, up from 46 percent in 2024, a sign that businesses are increasingly treating ransomware as a business continuity event rather than a straightforward payment decision.
The 2026 Outlook Business Leaders Should Plan Around
Three trends from 2025 are accelerating into 2026. First, AI-assisted phishing has made social engineering attacks harder to distinguish from legitimate communications — a trend that was emergent in 2025 and is becoming standard practice by year-end. Second, attackers have moved beyond encrypting local files toward targeting cloud environments, backup systems, and the management software businesses use to operate their IT — eliminating the recovery options that used to make ransomware survivable. Third, supply chain attacks have become the preferred method for scaling impact: compromise one vendor, reach hundreds of downstream businesses.
For a small business owner reading these trends, the actionable insight is not that the threat environment got worse — it’s that the threat environment is changing in specific, predictable ways. Businesses that update their defenses to account for AI-assisted attacks, cloud-targeting ransomware, and supply chain exposure will absorb the 2026 landscape differently than those operating on 2022-era assumptions.
The 9,251 attacks recorded in 2025 are not abstract statistics. They represent 9,251 decisions by specific attackers to target specific organizations they believed were within reach. Understanding what makes an organization reachable — and systematically removing those factors — is the most direct way business leaders can influence their own position in the 2026 numbers.
What Business Leaders Should Consider Before Year-End
- Review your software patch status before January 1st. Thirty-two percent of 2025 attacks entered through unpatched vulnerabilities. A simple audit of your critical business software — operating systems, remote access tools, financial applications — and ensuring all pending updates are applied is one of the highest-return security actions available at no additional cost.
- Verify that your backups are offline, encrypted, and tested. 2025 attacks increasingly targeted backup systems to eliminate recovery options. A backup that is connected to your network is a backup attackers can also encrypt. Offline backups, stored in a separate location and tested quarterly, remain the most reliable recovery mechanism after an incident.
- Enable multi-factor authentication on every system that allows remote access. Compromised credentials account for 23 percent of entry points. Multi-factor authentication blocks the vast majority of credential-based attacks, including those where an employee’s password was exposed in a prior breach.
- Set a calendar reminder for a vendor security review in Q1 2026. Supply chain attacks are accelerating. Schedule 30 minutes per key vendor to verify they carry cyber liability insurance, have completed security certifications, and can demonstrate how they protect data they hold on your behalf.
- Know your cyber insurance coverage before you need it. Review your policy now — not after an incident. Understand what triggers coverage, what the deductible is, what categories of loss are included, and whether your coverage limits reflect your actual recovery costs at 2025-era attack prices.
