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.

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.

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.

A massive phishing campaign is using invisible Unicode tag characters to evade security filters, according to researchers at Microsoft. This technique, known as “ASCII smuggling,” has grown popular over the past year for launching AI prompt injection attacks, but the same tactic can hide suspicious text in emails.

Attackers have used a new phishing platform called “BigBear 2.0” to target hundreds of organizations across more than forty countries, according to researchers at CloudSEK. In about 10% of cases, the phishing attacks were able to bypass multifactor authentication.

AI tools are drastically improving the speed of the reconnaissance stage of targeted social engineering attacks, according to researchers at ESET. Attackers can use these tools to trawl the internet for publicly available information about potential victims, and incorporate this information into personalized spear phishing attacks.

Threat actors are using phishing emails with blank SMTP sender fields to bypass Microsoft 365 security filters, according to researchers at ReliaQuest. Microsoft 365 Exchange Online uses a feature called “RejectDirectSend” to block unauthenticated Direct Send emails from an organization’s trusted domain. If an attacker omits the domain field from these emails, however, RejectDirectSend will no longer block the messages.

Researchers at Microsoft are tracking a social engineering campaign that uses passkey-themed lures to trick users into granting persistent access to their accounts and online work environments.

Threat actors are increasingly leveraging AI hallucinations to plant phishing links and other malicious content in AI output, IEEE Spectrum reports. Large language models (LLMs) sometimes fabricate information, including web domains, when answering users’ questions. Attackers are registering these hallucinated web domains to host phishing pages.

Researchers at Gen Digital are tracking a sophisticated social engineering campaign that’s using phony NDA documents to trick employees into moving the conversation to WhatsApp and personal email accounts. The attackers targeted an employee at Gen itself, but the employee recognized that it was a scam and played along to see what the attackers would do. The threat actors first impersonated a real Gen executive based in Dublin, who introduced a second impersonated person who claimed to work at PwC.

Researchers at INKY observed a major phishing campaign that used SVG (Scalable Vector Graphics) image files to deliver malicious JavaScript. While abuse of SVG files isn’t new, INKY says their use in phishing campaigns has exploded over the past year.

A recent survey from Experian found that 60% of companies report fraud losses that are “somewhat or significantly higher” than in previous years, with a majority of respondents citing AI-generated phishing attacks as their top AI-related fraud concern. “Businesses identify AI-generated phishing as the most common AI-enabled fraud risk at 53%,” the report says.

The U.S. Federal Bureau of Investigation (FBI) has issued an advisory warning of a wave of OAuth consent phishing attacks targeting “prominent victims, their family members, and personal acquaintances.” OAuth phishing is an increasingly popular social engineering tactic that tricks users into granting access to their accounts without handing over their passwords.

An employee at your company receives an email from hr@yourcompany.com. The domain matches. There is no warning banner. The message asks them to review a payment approval document. They click. That email was never sent by your HR team. An attacker sent it, and your own Microsoft email infrastructure delivered it, with no password and no credentials required.

With inboxes increasingly well guarded, cybercriminals are turning to a more vulnerable front in their attacks against your digital workforce. Voice is the fastest-growing attack vector, and it’s because it’s dangerously effective. According to Verizon’s 2026 Data Breach Investigation Report, phone-centric attacks are 40% more successful than traditional email-based phishing.

Quantum Readiness Day on 24 September is a useful reminder that the security work we do today is not only about preventing breaches tomorrow. It is about protecting data and digital trust for years to come.

Researchers at ZeroBEC are tracking a phishing platform called “Greatness” that’s been significantly upgraded since it surfaced in 2023. “Since its initial discovery, the platform has evolved significantly,” the researchers write.

In addition to everyday users, Google's infrastructure is trusted by email security gateways, enterprise firewalls and automated URL detonation platforms. Threat actors know this.

A new phishing kit is using generative AI to fully automate voice phishing (vishing) attacks, according to researchers at Group-IB. The phishing platform, called “Balonx,” includes a module dubbed “CallFlow” that the researchers say “represents a fundamental evolution” in the phishing-as-a-service market.

Researchers at Zimperium are tracking widespread phishing campaigns that use Browser-in-the-Browser (BitB) attacks to trick users into handing over their enterprise credentials.
