Fortinet's annual threat report reveals ransomware victims jumped from roughly 1,600 to nearly 8,000 globally in one year — driven by AI-powered crime tools. Small businesses are disproportionately affected.
The Numbers Are Staggering
On April 30, Fortinet released its 2026 annual threat report, and the headline figure demands attention: ransomware victims worldwide surged from approximately 1,600 to 7,831 year-over-year — a 389 percent increase. This is not a gradual trend. It is an explosion, and it is directly linked to the proliferation of AI-powered criminal tools now available on the dark web.
The report specifically called out crime kits like WormGPT, FraudGPT, and BruteForceAI — purpose-built AI tools designed for malicious use — as the primary accelerants behind the surge. These tools automate everything from vulnerability discovery to exploit generation to ransom negotiation, enabling attackers to operate at a volume that was simply impossible before AI.
The Speed Problem
Fortinet's data revealed another alarming metric: the time-to-exploit for critical outbreaks has shrunk to just 24 to 48 hours. In practical terms, this means that from the moment a vulnerability is publicly disclosed, attackers using AI tools can develop and deploy working exploits within a day or two — long before most small businesses have even become aware of the vulnerability, let alone applied the patch.
This compression of exploit timelines fundamentally changes the math of cybersecurity. Traditional approaches that relied on monthly or even weekly patching cycles are now dangerously inadequate. If a critical vulnerability is disclosed on a Monday and your next scheduled maintenance window is the following weekend, attackers have already had five full days to compromise your systems.
Why Small Businesses Are Caught in the Crossfire
Fortinet's report confirmed what many in the industry have observed anecdotally: small and medium-sized businesses are being hit at a disproportionate rate. AI-powered ransomware operations do not discriminate by company size — they scan broadly for any vulnerable target. A 10-person law firm with an exposed remote desktop port is just as visible to an automated attack tool as a multinational corporation.
The difference is that the law firm typically lacks the dedicated security team, incident response retainer, and tested recovery procedures that the enterprise has in place. When ransomware hits, the small business faces a starker choice: pay the ransom or risk weeks of downtime they cannot afford. The attackers know this, and it is reflected in their targeting.
Defending Against AI-Powered Ransomware
The same report that documents the threat also points toward the solution. Fortinet emphasized that organizations with mature security hygiene — multi-factor authentication, endpoint detection and response, network segmentation, and tested backup procedures — were significantly less likely to suffer successful ransomware attacks, even when targeted.
Make offline, tested backups your highest priority. If ransomware encrypts your systems and you have a clean, recent backup stored somewhere the attackers cannot reach, you can restore your operations without paying a ransom. Implement multi-factor authentication on every account without exception. Deploy endpoint detection and response software that uses behavioral analysis rather than signature-based detection — AI-powered ransomware often evades traditional antivirus. And work with a managed security provider that monitors your environment continuously, because the attackers are not waiting for business hours.
