VoidProxy phishing service targets Microsoft 365, Google accounts

Summary

Hide ▲

A new phishing-as-a-service (PhaaS) platform, VoidProxy, targets Microsoft 365 and Google accounts, including those protected by third-party single sign-on (SSO) providers like Okta. The platform uses adversary-in-the-middle (AitM) tactics to steal credentials, multi-factor authentication (MFA) codes, and session cookies in real time. The attack begins with emails from compromised accounts at email service providers, which include shortened links redirecting recipients to phishing sites. The phishing sites are hosted on disposable low-cost domains and protected by Cloudflare to hide their real IPs. VoidProxy's attack flow involves serving a Cloudflare CAPTCHA challenge, filtering traffic, and presenting phishing pages that mimic Microsoft or Google login screens. Federated accounts using Okta for SSO are redirected to a second-stage phishing page impersonating Microsoft 365 or Google SSO flows. The service's proxy server captures usernames, passwords, and MFA codes in transit, and intercepts session cookies for attackers. Okta Threat Intelligence researchers discovered the platform and noted that users with phishing-resistant authentications like Okta FastPass were protected from these attacks.

ForcedLeak Vulnerability in Salesforce Agentforce Exploited via AI Prompt Injection

A critical vulnerability in Salesforce Agentforce, named ForcedLeak, allowed attackers to exfiltrate sensitive CRM data through indirect prompt injection. The flaw affected organizations using Salesforce Agentforce with Web-to-Lead functionality enabled. The vulnerability was discovered and reported by Noma Security on July 28, 2025. Salesforce has since patched the issue and implemented additional security measures, including regaining control of an expired domain and preventing AI agent output from being sent to untrusted domains. The exploit involved manipulating the Description field in Web-to-Lead forms to execute malicious instructions, leading to data leakage. Salesforce has enforced a Trusted URL allowlist to mitigate the risk of similar attacks in the future. The ForcedLeak vulnerability is a critical vulnerability chain with a CVSS score of 9.4, described as a cross-site scripting (XSS) play for the AI era. The exploit involves embedding a malicious prompt in a Web-to-Lead form, which the AI agent processes, leading to data leakage. The attack could potentially lead to the exfiltration of internal communications, business strategy insights, and detailed customer information. Salesforce is addressing the root cause of the vulnerability by implementing more robust layers of defense for their models and agents.

Malicious npm package 'fezbox' uses QR codes to deliver cookie-stealing malware

A malicious npm package named 'fezbox' was discovered using QR codes to fetch and execute cookie-stealing malware. The package, disguised as a utility library, was downloaded at least 327 times before being removed from the npm registry. The malware targets user credentials and employs steganographic techniques to evade detection. The package was found to fetch a JPG image containing a QR code, which then executes a second-stage payload. The QR code is designed to be unusually dense and difficult to read with standard phone cameras, making it harder to detect. The package was published by a Chinese-speaking attacker using the alias 'janedu' and included multiple layers of obfuscation to evade detection. The malware specifically targets cookies to steal usernames and passwords, sending the stolen information via an HTTPS POST request to a command-and-control server. The package was removed and flagged as malware posing a supply-chain risk. The attacker's activity status on the npm registry remains unclear. The package's ReadMe mentioned a QR Code Module, making its existence seem legitimate. The package used reversed strings as an anti-analysis technique. The payload could read a web cookie and extract the username and password if both were present.

ShadowLeak: Undetectable Email Theft via AI Agents

A new attack vector, dubbed ShadowLeak, allows hackers to invisibly steal emails from users who integrate AI agents like ChatGPT with their email inboxes. The attack exploits the lack of visibility into AI processing on cloud infrastructure, making it undetectable to the user. The vulnerability was discovered by Radware and reported to OpenAI, which addressed it in August 2025. The attack involves embedding malicious code in emails, which the AI agent processes and acts upon without user awareness. The attack leverages an indirect prompt injection hidden in email HTML, using techniques like tiny fonts, white-on-white text, and layout tricks to remain undetected by the user. The attack can be extended to any connector that ChatGPT supports, including Box, Dropbox, GitHub, Google Drive, HubSpot, Microsoft Outlook, Notion, or SharePoint. The ShadowLeak attack targets users who connect AI agents to their email inboxes, such as those using ChatGPT with Gmail. The attack is non-detectable and leaves no trace on the user's network. The exploit involves embedding malicious code in emails, which the AI agent processes and acts upon, exfiltrating sensitive data to an attacker-controlled server. OpenAI acknowledged and fixed the issue in August 2025, but the exact details of the fix remain unclear. The exfiltration in ShadowLeak occurs directly within OpenAI's cloud environment, bypassing traditional security controls.

RaccoonO365 Phishing Network Disrupted by Microsoft and Cloudflare

The RaccoonO365 phishing network, a financially motivated threat group, was disrupted by Microsoft's Digital Crimes Unit (DCU) and Cloudflare. The operation, executed through a court order in the Southern District of New York, seized 338 domains used by the group since July 2024. The network targeted over 2,300 organizations in 94 countries, including at least 20 U.S. healthcare entities, and stole over 5,000 Microsoft 365 credentials. The RaccoonO365 network operated as a phishing-as-a-service (PhaaS) toolkit, marketed to cybercriminals via a subscription model on a private Telegram channel. The group used legitimate tools like Cloudflare Turnstile and Workers scripts to protect their phishing pages, making detection more challenging. The mastermind behind RaccoonO365 is believed to be Joshua Ogundipe, who received over $100,000 in cryptocurrency payments. The group is also suspected to collaborate with Russian-speaking cybercriminals. Cloudflare executed a three-day 'rugpull' against RaccoonO365, banning all identified domains, placing interstitial 'phish warning' pages, terminating associated Workers scripts, and suspending user accounts to prevent re-registration.

Increased Browser-Based Attacks Targeting Business Applications

Browser-based attacks targeting business applications have surged, exploiting modern work practices and decentralized internet apps. These attacks, including phishing, malicious OAuth integrations, and browser extensions, compromise business apps and data by targeting users. The attacks leverage various delivery channels and evasion techniques, making them difficult to detect and block. Phishing attacks have evolved to use non-email channels such as social media, instant messaging apps, and malicious search engine ads. These attacks often bypass traditional email security controls and are harder to detect. Attackers exploit the decentralized nature of modern work environments, targeting users across multiple apps and communication channels. Non-email phishing attacks can result in significant breaches, as seen in the 2023 Okta breach. The rise in these attacks highlights the need for enhanced browser security measures and better visibility into user activities within the browser.
