Black Arrow Cyber Threat Intelligence Briefing 19 June 2026

Welcome to this week’s Black Arrow Cyber Threat Intelligence Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Executive Summary

In our review of cyber security in the specialist and general media this week, we start with several high-profile alerts for business leaders. Organisations using Fortinet should assess their response to the discovery of tens of thousands of firewall credentials, and all organisations should assess the impact of a wider data leak of 24 billion records. We also provide more information on the Kali365 phishing-as-a-service platform targeting Microsoft accounts, which we included last week, and information on research regarding the number of malicious emails that bypass current security.

Over recent weeks, we have highlighted the need for organisations to manage the risks associated with using AI, and we provide further examples below. These include a Copilot risk recently remediated by Microsoft, and how AI is being used by attackers.

Distilling these insights into key actions, a message for business leaders is to prepare for organisational resilience in the event of a cyber incident. We work on this with clients across the world to achieve proportionality, which requires an objective understanding of the high-impact business activities in the organisation that must be prioritised in an incident, and a leadership team that has rehearsed together by considering the challenging and realistic ‘what if?’ scenarios to dispel assumptions. Contact us to discuss how to achieve this.


Top Cyber Stories of the Last Week

FortiBleed Exposes Admin Passwords for 75,000 Fortinet Firewalls

Security researchers have identified a major exposure of Fortinet firewall credentials affecting around 75,000 devices, with the dataset believed to cover roughly half of all internet-facing Fortinet firewalls. The exposed information reportedly includes usernames, email addresses and plain text passwords across 194 countries and more than 21,000 domains, including major companies, government bodies and critical infrastructure operators. Evidence suggests the data may have been prepared for sale in criminal markets or for coordinated deployment by threat actors, increasing the risk of attackers gaining remote access to affected networks, changing security settings or creating hidden administrator accounts.

24 Billion Records, Including Usernames and Passwords, Exposed in Colossal Data Leak: What Does That Mean for You?

Cybernews researchers identified an exposed database containing 24 billion records and more than 8.3TB of data, including usernames, email addresses, passwords and login URLs. Much of the data appears to come from infostealer malware, although researchers also identified records sourced from Telegram channels, breach compilations and other collections. The database was exposed between 12 and 15 June 2026, although researchers cannot confirm how many records were duplicates or how many people were affected. Reused passwords remain a key risk, particularly for accounts without multi-factor authentication.

Meet Kali365 — The ‘Amazon of Cybercrime’ Where Hackers Use AI to Completely Circumvent Multi-Factor Authentication

Kali365 is a phishing-as-a-service platform targeting Microsoft accounts, offering criminals ready-made tools to run phishing campaigns at scale. First identified by Huntress in May 2026, it includes more than 33 Microsoft themed templates and over 100 API endpoints. The platform gains access to accounts after users complete multi-factor authentication, using stolen session cookies and OAuth tokens rather than passwords alone. The FBI has warned that it can also use AI to read stolen email threads, assess fraud opportunities and draft replies based on the content of compromised conversations.

HP Warns 11% of Email Threats Bypass Security Gateways

HP research has found that 11% of email threats reaching users had already bypassed one or more security gateway scanners in Q1 2026. Email remained the leading route for malicious activity, accounting for 57% of threats, followed by web browser downloads at 24%. Attackers are increasingly abusing legitimate software, trusted platforms and familiar business processes to avoid detection, including remote access tools, fake software updates and shared design platforms. The findings suggest organisations should not rely solely on email security gateways, as a proportion of threats are reaching users after passing through existing scanning controls.

Cybercriminals Are Moving Away from Mass Phishing Campaigns

Zscaler reports that overall phishing activity fell by around 20% in both 2024 and 2025, but phishing campaigns are becoming more targeted. Criminals are moving away from mass email campaigns towards convincing business-themed messages, such as billing notices, onboarding documents and support requests. The services sector saw a 65.5% rise in phishing activity, while Microsoft and Google remained the most impersonated brands. Zscaler also found more than 95% of phishing activity used encrypted web traffic, with attackers increasingly using artificial intelligence tools to create fake websites and steal active login sessions. The research suggests organisations should look beyond blocked-email statistics when assessing phishing threats, as attackers are increasingly focusing on identities, active sessions and other techniques that are not reflected in email volumes.

https://www.helpnetsecurity.com/2026/06/12/zscaler-report-phishing-activity-trends/

One-Click Microsoft 365 Copilot Flaw Could Have Let Attackers Steal Emails, Files, and MFA Codes

A flaw in Microsoft 365 Copilot Enterprise Search could have allowed attackers to steal emails, calendar details, files and multi-factor authentication codes after a user clicked a genuine Microsoft link. Researchers found the issue could bypass traditional phishing checks because the link used a trusted Microsoft domain. Microsoft has fixed the issue through its managed service, and there is no evidence it was exploited. The research notes that Copilot Enterprise can access the same emails, files and business information available to the signed-in user, and recommends monitoring unusual Copilot activity and limiting the volume of data available for indexing.

“Dangerous” AI Models Are Coming No Matter What

Advanced AI models with hacking capabilities are expected to become more widely available within months, raising concerns for governments and business leaders alike. Anthropic recently took two models offline after US export controls, amid fears their safeguards could be bypassed. Experts argue that organisations and governments should prepare for a future in which advanced AI cyber capabilities are widely available, rather than assuming restrictions on individual models will prevent their emergence. While these models can help defenders find and fix weaknesses, they could also help criminals identify ways to exploit them.

Low-Skilled Attacker Used Claude, Codex to Breach 14 Companies

OALABS researchers found that a low-skilled attacker used AI coding agents to breach at least 14 companies, showing how these tools can reduce the expertise needed for cyber attacks. More than 1,000 recovered sessions showed the attacker used vague prompts, often framed as authorised security testing, while the AI helped find exposed systems, write exploit code and extract data. The tools raised few policy violations, and most were bypassed. The findings suggest AI coding agents can reduce the technical expertise required to conduct cyber attacks.

It’s Time to Update Incident Response for the AI Era

Gartner has warned that incident response must adapt as AI becomes embedded in business operations. It predicts that at least 80% of unauthorised AI transactions will stem from internal policy breaches, oversharing of information, unacceptable use or misguided AI behaviour, rather than malicious attacks. The challenge is that AI systems may create business risk while acting within their approved permissions. Gartner recommends that organisations review how they define AI-related incidents, improve oversight of AI activity, and ensure legal, compliance, HR and business teams are included in response planning.

https://www.techtarget.com/searchsecurity/news/366644312/Its-time-to-update-incident-response-for-the-AI-era

NCSC CEO: Hostile States Linked to Three-Quarters of Cyber Attacks Affecting UK’s Critical Systems

The UK’s NCSC has warned that hostile states are behind around three quarters of cyber attacks affecting the UK’s critical national infrastructure. More than 200 incidents involving essential services and their supporting systems were handled in the year to May 2026, with Russia, China and Iran identified as examples of hostile states of concern. The warning highlights the importance of understanding exposure to threats, strengthening security fundamentals and ensuring organisations can continue operating and recover quickly after an attack. The NCSC also expects artificial intelligence to increase the scale at which attackers can identify and exploit vulnerable legacy technology by 2028.

Over Two-Thirds of Security Pros Say Cyber Is Getting Harder

A new ISSA and Omdia study of 380 cyber security professionals found that 68% believe their role has become harder over the past two years. Many report being excluded from key technology decisions, with 72% saying this creates barriers to stronger security. Stress is also rising, with 47% considering leaving their role or the profession in the past 12 to 18 months. Only 29% rated their organisation’s cyber security culture as advanced, with respondents identifying increased training, investments in the right resources, stronger cyber hygiene and closer collaboration between security and IT teams as key areas for improvement.
