Proofpoint's 2026 AI-Era Ransomware Report (published July 22, 2026; survey of 953 cybersecurity professionals across 12 countries and 20 industries, fielded March-April 2026) found that 65% of
On July 22, 2026, Proofpoint published its 2026 AI-Era Ransomware Report, a global survey of 953 cybersecurity professionals spanning 12 countries (United States, United Kingdom, France, Germany, Italy, Spain, United Arab Emirates, Australia, Japan, Singapore, India, and Brazil) and 20 industries, fielded March-April 2026. The headline finding is that 65% of organizations that suffered a ransomware attack said artificial intelligence made the attack more effective (28% said significantly more effective, 37% somewhat more effective, versus roughly 9-11% who saw no evidence of AI involvement).
The report frames this not as a new ransomware variant or a single incident, but as a measurable quality shift in the initial-access lure: attackers are using AI to generate more convincing phishing emails, write more targeted impersonation and Business Email Compromise (BEC) messages, and conduct faster reconnaissance of an organization's structure and internal communication patterns before ever sending a lure. Proofpoint CSO Ryan Kalember summarized it as: "AI hasn't fundamentally changed ransomware, but it has materially improved the attacks that lead to ransomware."
Quantitatively, respondents identified malicious links (47% globally), malicious attachments (46%), credential harvesting (36%), and Business Email Compromise (35%) as the leading initial-access vectors preceding ransomware deployment. Regional breakouts show significant variance and, in some markets, additional vectors: the UAE reported the highest rates of QR-code phishing ("quishing," 55%) and telephone-oriented attack delivery/vishing (45%), alongside the highest AI-effectiveness rate globally (83%). Roughly 38-40% of global respondents said the lure appeared legitimate enough that employees did not suspect it, and about a third (33%) said email security controls failed to detect the attack outright, with another quarter (25%) citing misconfiguration or control gaps.
The report also documents the broader evolution of ransomware from a pure encryption event into a sustained, multi-channel extortion campaign: 65-67% of global respondents (60% in the US, 66% in the UK, 83% in the UAE) confirmed data was stolen before or alongside encryption, giving attackers additional leverage beyond the decryption key. 54% of affected organizations paid a ransom (93% in the US, 58% in the UK, 81% in the UAE), and critically, 37% of those who paid (22% UK, 47% UAE) later faced a second extortion demand — evidence that payment does not reliably end the incident. Proofpoint India Country Manager Bikramdeep Singh framed the underlying dynamic bluntly: ransomware "succeeds by exploiting people's trust, not just systems."
No CVE, malware family, C2 infrastructure, or named threat actor/group is cited in this report — it is a cross-industry trend/perception survey, not an incident writeup. It is included in this platform as a sourced, quantified signal that AI is measurably raising the success rate of the phishing/BEC/credential-theft lures that most ransomware intrusions still begin with, which should inform email-security tuning, awareness training, and pre-ransomware detection (data-theft, credential misuse) priorities.
