"Across the incidents examined in this report, evidence of AI involvement was the norm, not the exception," said the 2026 AI-Era Ransomware Report, published on July 22.
AI tooling has changed the attacker playbook — and the results are measurable
A global survey of cybersecurity professionals conducted by Proofpoint found that among organizations hit by ransomware, 65% reported AI increased the effectiveness of the attack. According to the same report, attackers leveraged AI tools to produce more convincing phishing emails, impersonation attacks and credential-theft campaigns — capabilities that the report ties directly to the rise in attack success.
Initial entry points: links, attachments and credential harvesting
The incidents analyzed in the report point to the same starting points most defenders already monitor, but with an important twist. Proofpoint’s data shows 47% of examined incidents involved malicious links at some stage of the attack chain, 46% involved malicious attachments, and 36% involved credential harvesting. In other words, human interaction remained central to initial compromise even as AI sharpened the lure.
Why people and trusted communications matter
Proofpoint’s respondents explained how AI changed the calculus of clicking. Forty percent said the initial lure appeared legitimate enough that employees did not suspect anything was wrong. The report contrasts that with a prior era when suspicious emails often bore telltale signs — clumsy phrasing, mismatched logos, or login pages that “don’t look quite right.” With AI, those subtle defects can be smoothed away, producing messages that read and look like legitimate business communications.
Technical controls failed to catch many of the AI-enabled attacks
The report also documents gaps in enterprise defenses. One-third of surveyed organizations said existing email security controls failed to detect the attack entirely; another quarter cited misconfiguration or gaps in security controls. Proofpoint frames this not as an endpoint problem but as an attack sequence that begins with people, identities and trusted communications — and therefore requires prevention at the point of entry.
What this means for technologists, procurement leaders, and end users
- Technologists and security teams: the report urges a shift toward stopping attacks where they start — at email and identity — rather than treating ransomware primarily as an endpoint or recovery issue. Proofpoint recommends focusing on stopping attacks at the point of entry, protecting identities from compromise, and responding before attackers can turn access into extortion.
- Procurement and product owners: because a third of respondents reported email security controls failed to detect attacks and a quarter cited misconfiguration, buyers and administrators will need to examine both product detection capabilities and deployment hygiene to address gaps the report highlights.
- End users and corporate communicators: with 40% of victims saying the lure looked legitimate, the report underscores that user-facing communications and training remain relevant — not as the only line of defense, but as a necessary complement to controls that can be outpaced by AI-crafted content.
Ryan Kalember, chief strategy officer at Proofpoint, summarized the shift bluntly: "AI hasn't fundamentally changed ransomware, but it has materially improved the attacks that lead to ransomware." He added that attackers are now using AI to scale exploitation of human trust through convincing phishing, scripts and credential-theft campaigns.
The 2026 AI-Era Ransomware Report leaves a clear, if urgent, prescription for organizations trying to blunt this new phase of attacks: stop attacks at the point of entry, protect identities from compromise, and respond before attackers can turn access into extortion. That directive is short on technical detail in the press summary but long on implication — that a growing share of ransomware success stems from AI-enhanced social engineering that both people and existing defenses routinely miss.
