[NEW FEATURE] KnowBe4 Releases Deepfake Training to Combat AI Threats!

Deepfakes have officially moved from “someday risk” to “right now” threat. In the last 12 months, more than 62% of organizations have been targeted by a deepfake attack. That’s a social engineering problem, because these scams are designed to bypass your tools and go straight to your users.

That’s why I’m excited to share this KnowBe4 launch: Deepfake Training.

Here’s what makes it different. Instead of using generic examples, you can create a deepfake training video featuring a leader from your own organization. Picture an employee getting a “video message from the CFO” asking for an urgent wire transfer or credentials.

When people see how believable AI impersonation can be, using familiar faces and voices, it sticks. That’s how you strengthen the human firewall and build a culture where ‘think before you click’ becomes muscle memory.

This also helps you prove ROI. A highly personalized experience drives higher engagement and completion, which makes it easier to show measurable improvement and secure continued support for your security program.

My recommendation: pilot it with finance and IT first, track completion, then expand across your organization.

Availability is simple:

• If you already have AIDA, it’s available today.
• Admins can access it under Training → Deepfakes.
• Diamond-level customers can also try it via the AIDA Orchestration technical preview for three months.

If deepfakes are on your 2026 risk list, don’t wait for the first incident. Train for it now, before “the CEO” calls.

NEW! Deepfake Training: A Strategic Advantage Against Emerging Threats

Deepfake attacks have become more compelling and realistic than ever before.

Attackers are impersonating trusted leaders with convincing videos and voice, making it harder for employees to know what is real. Traditional awareness training is a good start, but nothing replaces first-hand exposure to real and synthetic content when it comes to telling deepfake videos from authentic ones.

That’s why we’re introducing KnowBe4’s Deepfake Training Content. This new capability transforms abstract risk into an unforgettable, high-engagement training moment that demonstrates how convincing AI-powered social engineering has become and delivers clear, actionable guidance on how to detect these attacks.

How it Works

KnowBe4 makes it easy to generate deepfake training tailored to your organization. In just minutes you can create hyper-realistic deepfakes that deliver scalable, high-impact training experiences.

1. Choose a Leader to Feature – Select a CEO, executive or another recognizable leader your employees trust.
2. Upload a Short Sample – Provide a brief video and audio clip of that person, then select a deepfake scenario to generate.
3. Generate Your Custom Deepfake Training Experience – KnowBe4’s system creates a hyper-realistic deepfake that your employees can experience within a controlled training environment. These deepfakes demonstrate how convincing AI impersonation can be and teach employees what cues to look out for.
4. Deploy in Any Training Campaign – Add the deepfake module to existing training plans or use it as a high-impact standalone experience.
5. Measure Improvement – Track completion, engagement and performance over time to show real behavior change.

Why it Matters

• Deepfake attacks are increasing fast. Employees need training that reflects today’s threat landscape.
• Personalized content captures attention. A custom deepfake training experience featuring someone your employees know drives higher engagement than generic material.
• Security teams need measurable impact. Deepfake training drives exceptionally high completion rates, making it easy for security leaders to prove measurable behavior change.
• It prepares your employees for what’s coming next. Deepfakes are becoming a standard tool for social engineering, and your KnowBe4 training now reflects that reality.

Join our upcoming webinar, NEW Deepfake Training: Empowering Your Users to Recognize What AI Can Fake, to learn how deepfake attacks work, how to train users to identify them and how to create your own custom deepfake training experience with KnowBe4.

[Beware] Microsoft Teams ‘Chat With Anyone’ Invites Aren’t Always Safe

Researchers at CyberProof warn that threat actors are launching phishing attacks via Microsoft Teams’ “Chat with Anyone” feature, which lets external users send direct messages via email addresses.

“Microsoft Teams now allows users to send direct chat invitations to any email address, even if recipients aren’t part of a Teams tenant,” the researchers explain. “Users can start chats with external participants who join as guests governed by Entra B2B Guest policies.”

In this case, an attacker sent direct messages to Teams users, posing as IT support. Several employees received these messages and were tricked into joining remote support sessions using Windows Quick Assist.

“The attacker then contacted the user as IT Support on the very next day, started a Teams call and tricked the user into initiating Quick Assist by sending a phishing URL, where the user needed to provide login credentials to download Quick Assist,” CyberProof says. After the user entered their Microsoft credentials, the attacker installed an infostealer on their computer.

The researchers warn that organizations should prepare for more of these attacks as the “Chat with Anyone” feature is fully released in the coming weeks. Users should be wary of unsolicited messages, even if they appear to come from known colleagues.

“Since its rollout, the MS Teams feature, scheduled for early release in November 2025 and the full global rollout planned by January 2026, has raised concern about data exposure and compliance risks,” the researchers write. “We believe this could leave the door open for a potential escalation in more malware and phishing attacks.”

Report: Phishing Has Surged 400% Year-Over-Year

Researchers at SpyCloud have observed a 400% year-over-year increase in successful phishing attacks, with a disproportionate number of attacks targeting corporate accounts.

“The company tracked a 400% year-over-year increase in successfully phished identities, with nearly 40% of the 28+ million recaptured phished records containing a business email address – compared to just 11.5% in recaptured malware data,” the researchers write.

“The result is a warning to enterprises that their workforce is three times more likely to be targeted with phishing attacks than infostealer malware.”

The researchers warn that these findings show that attackers are increasingly using phishing as an initial access vector into corporate networks.

“The findings reinforce a growing shift in cybercriminals’ strategy: phishing is now the preferred gateway into enterprise environments, and SpyCloud sees this trend continuing in 2026,” SpyCloud says.

“Threat actors are using this access as a launchpad for follow-on attacks, with SpyCloud reporting in its 2025 Identity Threat Report that phishing is now the leading entry point for ransomware, accounting for 35% of all ransomware infections.”

Trevor Hilligoss, SpyCloud’s Head of Security Research, said in a statement, “Phishing is now one of the most scalable tools cybercriminals use to breach enterprise environments.

“Cybercrime enablement services, like phishing-as-a-service kits that automate convincing lures and adversary-in-the-middle tactics that capture MFA tokens and session cookies, put advanced tactics into the hands of low-skilled actors, making it easier than ever to compromise users at scale.”

AI-powered security awareness training can give your organization an essential layer of defense against phishing and other social engineering attacks. KnowBe4 empowers your workforce to make smarter security decisions every day.

Over 70,000 organizations worldwide trust the KnowBe4 HRM+ platform to strengthen their security culture and reduce human risk.

Russian Spear Phishing Campaign Targets European Governments

A Russian state-sponsored spear phishing campaign is targeting European and U.S. government workers, as well as individuals working on European foreign policy matters. The campaign impersonated European security conferences to breach users’ Microsoft 365 accounts.

“In October 2025, Volexity worked an incident where a user’s Microsoft 365 account had been identified as compromised following the detection of anomalous login activity,” the researchers write. “An investigation into the incident found the user had received a spear-phishing email leading to an OAuth authentication workflow.

“The email had come from an account the user had recently corresponded with, and it was a continuation of an existing and legitimate thread related to the upcoming Belgrade Security Conference in Serbia.

“The attackers establish conversations with the targeted users in order to build rapport before sending them anything malicious.

“This method of phishing would further require the targeted user to send to the attacker a code generated by Microsoft that would be found in the URL bar of the user’s browser,” the researchers write. “There was no email correspondence indicating what to do with this code, so Volexity suspected the attacker was communicating with the victim outside of email.

“Working with its customer, Volexity found the threat actor had been actively communicating with this targeted user on WhatsApp. The attacker had reached out under two different identities related to the Belgrade Security Conference, both of which had been compromised.”

Notably, the lures were so effective that victims forwarded the phishing emails to their colleagues. “Referencing upcoming events as a pretext to engage users has also proven effective,” the researchers write. “Volexity has observed users directly forwarding event invitations to other users within their organization who may be suitable attendees.

“Effectively, users help the attacker build a target list for both that particular phishing campaign and others in the future.” KnowBe4 empowers your workforce to make smarter security decisions every day. Over 70,000 organizations worldwide trust the KnowBe4 HRM+ platform to strengthen their security culture and reduce human risk.

Warning: Phishing Campaign Targets U.S. Universities

Threat actors are using the open-source phishing framework Evilginx to target universities across the United States, according to researchers at Infoblox.

The attackers have targeted at least 18 universities and educational entities since April 2025, using phishing pages that spoofed student single sign-on (SSO) portals.

“In the campaigns we analyzed, students were targeted via personalized emails that contained TinyURL links,” Infoblox says. “These short links redirected to phishing URLs dynamically generated from Evilginx phishlets—configuration files that define how the proxy interacts between the victim’s device and the legitimate site.

“Each phishing URL used a subdomain that impersonated the target brand and a URI with eight random alphabetic characters (case-insensitive). The URLs expired within 24 hours, a tactic to limit exposure and evade detection. When victims accessed the phishing URL, Evilginx proxied the legitimate login flows in real time, making traffic appear normal and bypassing MFA.”

Notably, Evilginx has built-in measures that help its attacks avoid detection, allowing unskilled threat actors to launch sophisticated, evasive phishing campaigns.

“The low detection rates across the cybersecurity community highlight how effective Evilginx’s evasion techniques have become,” the researchers write. “Recent versions, such as Evilginx Pro, add features that make detection even harder.

“These include default use of wildcard TLS certificates, bot filtering through advanced fingerprinting like JA4, decoy web pages, improved integration with DNS providers (e.g., Cloudflare, DigitalOcean), multi-domain support for phishlets and JavaScript obfuscation. As Evilginx continues to mature, identifying its phishing URLs will only become more challenging.”
