KATARU is an IoT malware variant discovered in August 2026 through Telnet credential brute-forcing against a honeypot from Vietnam. While maintaining traditional Mirai-style botnet capabilities, it distinguishes itself through an extensive feature set including multiple Linux local privilege escalation exploits, comprehensive persistence mechanisms across Linux and embedded platforms, encrypted C2 communications using X25519 and ChaCha20-Poly1305, anti-analysis techniques, and decoy traffic generation. Implementation artifacts strongly suggest AI-assisted development, evidenced by architecture-mismatched x86 shellcode in ARM binaries, RFC test vectors as configuration values, and untested cross-platform persistence logic. The malware attempts various privilege escalation paths through system misconfigurations and public exploits, establishes persistence across numerous startup mechanisms, and supports multiple DDoS attack vectors alongside SSH brute-forcing capabilities.

Huntress researchers discovered Knight Office, a phishing kit utilizing Adversary-in-the-Middle techniques to steal Microsoft 365 session tokens. The attack chain begins with DocuSign-themed phishing emails containing redirects through Monday.com and compromised Joomla websites. Victims are directed to credential capture pages where session tokens are harvested and fed into the Knight Office console. These stolen tokens enable attackers to bypass multi-factor authentication entirely by using already-authenticated sessions. In one incident, attackers registered rogue devices in Microsoft Entra ID and bound Windows Hello for Business credentials for persistence. Analysis revealed nine phishing attacks linked to this kit over two weeks, with hundreds of related emails reported since April. The console, hosted at IP 104.37.188.94, manages at least 25 phishing domains using .vu top-level domains.

A sophisticated multi-stage phishing operation has been active since April 2025, systematically exploiting legitimate SaaS platforms and cloud services to steal corporate credentials. The campaign utilizes 232 phishing domains and 80 command-and-control servers, primarily impersonating human resources consulting firms, with Robert Half Inc. and Aquent LLC representing 50% of targeted brands. Attackers leverage legitimate platforms like Salesforce, SendGrid, and Zoho for email delivery, directing victims to fake Calendly interview pages that mimic real recruiter identities. The operation deploys an adversary-in-the-middle toolkit using browser-in-the-box techniques to create replica Google sign-in pages, capable of harvesting credentials and bypassing MFA through email, SMS, Google Authenticator, and prompt notifications. The campaign specifically targets corporate email accounts, filtering out personal providers, with stolen data exfiltrated to Render-hosted servers and Telegram bots.

A misconfigured Python HTTP server on a Budapest VPS exposed the complete operational infrastructure of three distinct phishing operators. The investigation uncovered codemado, an Egyptian threat actor operating since 2018, running a full AiTM platform with custom tools including MaDoO Blaster; saroula01, deploying OAuth Device Code Flow attacks that accumulated 218 victims across 12 countries over a year; and mail-argenta, a Nigerian operator identified through infostealer logs containing his own credentials. All three actors leveraged customized Evilginx forks and AI-assisted development to build MFA-bypass infrastructure from public GitHub repositories. The campaigns targeted Microsoft 365 accounts primarily, with codemado maintaining ties to RockyBelling's "The Quarry" cybercrime ecosystem. The exposed server contained phishing configurations, credential logs, RMM installers, combolists, and Telegram session files, revealing sustained operations from at least January 2025 through May 2026.

Blacksite is a newly identified adversary-in-the-middle phishing-as-a-service offering sold alongside Cloaked.gg, a cloaking platform that conceals phishing infrastructure from automated security analysis. The kit operates as a reverse-proxy that intercepts authentication tokens, session cookies, and 2FA codes in real time, enabling full account takeover even against MFA-protected accounts. Cloaked.gg blocks traffic from AWS, Google Cloud, and Azure networks while serving AI-generated decoy pages to suspected scanners, making malicious URLs appear benign during automated analysis. Priced between $600-$1,000 monthly, the service commercializes sophisticated AiTM techniques, lowering technical barriers for attackers. The pairing of credential theft capabilities with anti-detection infrastructure creates a split-view environment where security tools see harmless content while intended victims are routed to live phishing pages targeting consumer, financial, and enterprise identity systems.

Multiple phishing campaigns are exploiting the FIFA World Cup 2026 event to target mobile users globally. These campaigns use typosquatting, institutional spoofing, and impersonation of major sports retailers to harvest credentials. A sophisticated recruitment fraud campaign also targets corporate Google Workspace accounts with an Adversary-in-the-Middle platform capable of bypassing MFA. Attack vectors include SMS, WhatsApp, and search engines, leveraging emotional urgency and ticket scarcity. This creates risks for enterprises as employees may access work resources via compromised personal devices.

Security researchers gained direct access to Doko's Panel, a real-time phishing platform used in criminal campaigns by ShinyHunters and BlackFile groups. The investigation revealed four distinct infrastructure clusters operating independently customized variants of the tooling. Attacks combine voice phishing with adversary-in-the-middle techniques targeting enterprise identity providers like Okta, Microsoft, and Google, as well as cryptocurrency exchanges. Operators call victims impersonating IT helpdesk staff, directing them to combosquatted domains where credentials and MFA tokens are manually relayed in real-time. Confirmed breaches include SoundCloud (30M records), Match Group (10M records), Betterment (20M records), and Crunchbase. Over 400 domains have been identified linked to these operations. Evidence shows extensive use of AI language models in developing phishing infrastructure, with operators leveraging legitimate services to rapidly deploy and rotate attack infrastructure.

A sophisticated credential theft campaign targeting over 35,000 users across 13,000 organizations was observed between April 14-16, 2026. The operation primarily impacted the United States, particularly healthcare and financial services sectors. Attackers used code of conduct themed phishing emails masquerading as internal compliance communications, sent through legitimate email delivery services from attacker-controlled domains. Victims received polished HTML emails with PDF attachments containing fake disciplinary logs and CAPTCHA gates to evade automated analysis. The multi-stage attack chain ultimately directed users to counterfeit Microsoft authentication pages operating as adversary-in-the-middle infrastructure, enabling real-time interception of credentials and session tokens while bypassing multi-factor authentication defenses.

Microsoft Incident Response researchers identified Storm-2755, a financially motivated threat actor conducting payroll pirate attacks against Canadian users. The campaign uses malvertising and SEO poisoning on generic search terms like "Office 365" to lure victims to a fraudulent sign-in page. Through adversary-in-the-middle techniques, the actor captures authentication tokens and session cookies, bypassing MFA protections. Storm-2755 maintains persistence using Axios HTTP client to replay stolen tokens, then conducts discovery for payroll and HR contacts. The actor impersonates compromised users to socially engineer HR staff or directly manipulates payroll systems like Workday. Malicious inbox rules hide correspondence from victims. Attacks resulted in direct financial losses through redirected salary payments to attacker-controlled bank accounts.

A new phishing campaign is targeting TikTok for Business accounts using adversary-in-the-middle (AitM) techniques. The attackers employ Cloudflare Turnstile to evade detection and create convincing lookalike pages impersonating TikTok for Business or Google Careers. Victims are tricked into clicking malicious links, leading to credential theft. The campaign aims to seize control of business accounts, which can be used for malvertising and malware distribution. Multiple domains are involved in hosting the phishing pages. Additionally, a separate campaign using SVG file attachments to deliver malware has been observed in Venezuela, with potential links to BianLian ransomware activity.
