Attackers are continually finding new ways to refine business email compromise (BEC) attacks, according to Douglas McKee, Director of Vulnerability Intelligence at Rapid7. When attackers compromise trusted tools and accounts, they can manipulate victims’ view of reality. One way attackers can achieve this is through what McKee calls “calendar warfare,” in which attackers use calendar meetings to trick users into falling for attacks.

Agent Risk Manager, KnowBe4’s AI agent security product in the KnowBe4 Platform, integrates with the Claude Compliance API to help organizations monitor Claude activity and detect risks in real time. Today, that integration is featured in Claude’s Compliance API milestone announcement.

41% of CISOs said an audio deepfake targeted their organization within the last 12 months, according to a new survey by Gartner. Additionally, 36% of respondents said employees were targeted by deepfake video calls over the past year. Craig Porter, Director Analyst at Gartner, noted that social engineering and human deception remain at the core of these AI-assisted attacks.

The U.S. Federal Bureau of Investigation (FBI) has issued an alert warning that widespread fraud campaigns are impersonating law enforcement or government officials to trick users into handing over money or sensitive information.

Let’s face it: inertia is often the most common yet most dangerous adversary when it comes to acquiring new technology, especially in cybersecurity. There is still a persistent assumption across many organizations that email security architecture that worked three years ago is still good enough for today’s threat landscape. Even when security teams suspect gaps, the friction of evaluating, procuring and operationalizing new technology creates a massive organizational bottleneck.

Threat actors are using a new phishing kit called “GhostCode” to target sales teams with phony business inquiries, according to researchers at eSentire. The threat actors begin the attack using the targeted company’s web contact form, so the messages won’t be blocked by security filters.

China-based cybercriminals are using a sophisticated phishing-as-a-service platform called the “Outsider Phishing Kit” to launch massive phishing campaigns around the world, according to researchers at Group-IB. “The scale of this operation is staggering,” the researchers write. “From December 2025 to May 2026, Group-IB has identified over 100,000 phishing pages targeting 54+ countries, leveraging 267 (and growing) phishing templates.

Scammers are using AI to generate phishing pages that impersonate antivirus products, according to Malwarebytes.

For over a decade, the security industry has focused on one thing: training people not to click. Phishing simulations, awareness campaigns, behavioral nudges. The human is the attack surface. Harden the human, harden the org. And that's still true. But it's no longer the whole picture.

Researchers at Microsoft are tracking an AI-assisted phishing campaign that sent over a million emails attempting to conduct payment diversion scams.
