A sophisticated phishing campaign impersonates AI advertising products from major platforms using a Browser-in-the-Browser technique to steal credentials and bypass multi-factor authentication (MFA) in real-time. The campaign targets advertising account managers and recruiters, leveraging a shared backend infrastructure and reusing code across multiple fake brands. It also includes refund scams and fake recruitment sites connected to the same infrastructure.
A widespread IT impersonation and voice-phishing campaign designated PREY-0058 is actively targeting Microsoft 365 and SaaS platforms. Threat actors impersonate IT helpdesk staff via phone or text to trick executives and senior personnel into divulging credentials through adversary-in-the-middle phishing portals. After bypassing multi-factor authentication, attackers conduct rapid automated data exfiltration across email, file storage, and cloud repositories without deploying ransomware. The operation relies heavily on NodeMaven residential proxy infrastructure to blend with legitimate traffic. Extortion demands are delivered via TOX messaging within hours of compromise, typically with 72-hour deadlines and threats of public data exposure. The campaign exhibits tradecraft overlapping with UNC6671 and involves multiple extortionware brands including BlackFile, Redact, Pink, and Helix.
Device code phishing exploits the OAuth 2.0 device authorization grant, a legitimate authentication feature designed for input-limited devices like smart TVs. Attackers initiate a device-code request with Microsoft, receive a valid code, then trick victims into approving it through social engineering. The victim authenticates on genuine Microsoft pages and completes MFA, but the session tokens are issued to the attacker instead. When targeting the Microsoft Authentication Broker, attackers can register rogue devices and obtain long-lived refresh tokens for persistent access. A recent campaign used sophisticated multi-stage delivery chains involving Google Sites, compromised website redirectors, and fake document-sharing portals. After successful authentication, attackers registered multiple devices, created hidden mailbox rules, and used compromised accounts to send additional phishing emails, all without touching victim endpoints.
A sophisticated adversary-in-the-middle phishing campaign is targeting universities, enterprises, and multinational institutions including EU and UN agencies. Active since May 2026, the operation leverages compromised organizational email accounts to distribute procurement-themed lures that mimic requests for information, bid invitations, and project documentation. Victims are redirected through fake document portals, CAPTCHA verification stages, and cloned authentication pages impersonating Microsoft, OpenGov, and financial institutions. The attacker rotates between multiple AiTM phishing kits including EvilProxy, FlowerStorm, and Kali365 to intercept MFA-protected sessions in real time, capturing session tokens and cookies to establish authenticated access. Rather than using newly registered domains, the actor compromises aged domains that have been dormant for years, injecting PHP files to host phishing infrastructure and evade detection through domain reputation systems.

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.
Phishing attacks have surged in 2026 as AI-powered phishing-as-a-service kits enable threat actors to bypass multi-factor authentication and harvest OAuth tokens at scale. Two phishing tools were identified in active campaigns: Jalisco, a device code phishing toolkit that provisions fresh OAuth codes in real time to defeat time-based security controls, and OmegaLord, a credential harvester that captures phone numbers alongside passwords to intercept MFA. Both tools demonstrate that attackers are engineering sophisticated methods to defeat authentication controls. These toolkits are part of a broader ecosystem that includes AI-powered PhaaS kits like EvilTokens and Kali365, which leverage legitimate cloud platforms to evade detection. Following compromise, attackers establish persistence by enrolling multiple devices to victim Entra ID tenants, enabling access that survives password resets and extends the window for data exfiltration and extortion.
An unknown threat actor exploited Meta's Business Account Manager service to send phishing emails from legitimate Meta addresses between November 2025 and June 2026. The attackers manipulated the business partner mechanism by embedding URLs in the business name field, causing emails to appear as legitimate Meta communications. The campaign evolved to incorporate Facebook Messenger chatbots and exfiltrated stolen credentials, MFA codes, phone numbers, and identity documents to a private Telegram channel. The phishing pages impersonated Meta's Agency Partner Program and Verified badge services, targeting businesses to capture account credentials. Meta responded by implementing detections and blocking accounts attempting to use URLs in business names. Vietnamese language elements in the exfiltration process suggest the attackers' possible origin.
Between June 16 and 19, 2026, a sophisticated adversary-in-the-middle phishing campaign targeted AWS console users through three domains registered within 48 hours and hosted on Cloudflare. The campaign impersonated AWS login pages and captured credentials along with real-time multi-factor authentication codes through email, SMS, and authenticator apps. Phishing emails were delivered through legitimate platforms like SendGrid and Nimbu to bypass spam filters. The kit employed JavaScript-based credential harvesting with victim validation through encrypted URL parameters, preventing sandbox analysis. Targets were primarily US-based software engineers and engineering leadership, suggesting a curated target list rather than mass phishing. The same kit was linked to concurrent SendGrid impersonation campaigns and previous cryptocurrency wallet targeting since July 2025. The small sample of fewer than 50 targeted email addresses indicates highly selective targeting of technical personnel with AWS access.
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.
A new extortion group called Pink, tracked as cluster CL-CRI-1147, employs voice phishing and fake IT helpdesk impersonation to compromise organizations. The gang steals employee credentials, bypasses multi-factor authentication, and exfiltrates data from cloud storage platforms like SharePoint and OneDrive. Pink threatens to leak stolen information unless ransom demands are met, setting 72-hour deadlines. The group's data-leak site launched on May 31, 2026. This approach mirrors tactics popularized by Lapsus$, Scattered Spider, and ShinyHunters. Incident responders link Pink to The Com, a loosely connected network of English-speaking hackers and extortionists. Attackers use compromised victim accounts and internal Teams messages for extortion communications, reusing domains across multiple targets.
A significant expansion of the Kali365 phishing-as-a-service operation has been observed, now targeting multiple platforms beyond Microsoft 365. The operator abuses OAuth 2.0 device authorization flows to bypass MFA and steal authentication tokens. Key discoveries include a live command-and-control panel infrastructure, a phishing campaign impersonating MAX Messenger (Russia's state-backed messaging platform with 110 million users) through fake prize-claim flows, and a cluster of 126 malicious hosts impersonating services including Microsoft Outlook, Okta SSO, Xerox DocuShare, Mail.ru, Yandex Disk, and Odnoklassniki.
