Update (July 30): A table listing the new names of select prominent threat actors was appended to this post. Introduction Today, Google Threat Intelligence Group (GTIG) will begin rolling out a unified naming schema for tracking threat actors. This new naming taxonomy represents an effort to standardize tracking across platforms and public reporting. Why are we Adopting a Different Naming System? Historically, Mandiant and Google’s Threat Analysis Group (TAG) maintained distinct tracking system…
This vulnerability allows local attackers to escape the model runner sandbox on affected installations of Docker Desktop for macOS. An attacker must first obtain the ability to execute low-privileged code within the sandbox in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 8.8.

Written by: Jules Czarniak Introduction As highlighted in the Mandiant M-Trends 2026 report, the mean time-to-exploit (TTE) has dropped to -7 days, meaning vulnerabilities are often exploited a week before a patch even exists. To keep pace, many security teams are exploring how to integrate large language model (LLM) agents into their codebases, development environments and continuous integration and continuous delivery (CI/CD) pipelines for automated vulnerability discovery and remediation. Ho…

Written by: Corné de Jong Introduction Mandiant security assessments frequently identify publicly exposed serverless applications that lack authentication, often as a result of specific business requirements. Serverless deployments typically run custom-developed code that incorporates third-party packages, making them targets for a wide range of application-level attacks, including: Local and Remote File Inclusion (LFI/RFI) Command Injection Successful exploitation of these vulnerabilities can …
56Critical510Important3Moderate0LowMicrosoft addresses 569 CVEs in the largest Patch Tuesday release yet. This month’s release includes three zero-days, two of which were exploited in the wild.Microsoft patched 569 CVEs in its July 2026 Patch Tuesday release, with 56 rated critical, 510 rated as important, and 3 rated as moderate. This marks the largest Patch Tuesday release ever, crushing the previous record of 198 CVEs in June. Last week, Microsoft announced that its multi-model agentic scann…
Written by: Shebin Mathew Introduction The "Golden SAML" technique, first described by CyberArk researchers in 2017, and further detailed by Mandiant researchers in 2021, remains one of the most effective methods for threat actors to forge identity assertions in the Microsoft ecosystem. By obtaining the private key of an ADFS token-signing certificate, an attacker can authenticate as any user to any SAML-federated application, bypassing multifactor authentication (MFA), conditional access, and …

Introduction Mandiant and Google Threat Intelligence Group (GTIG) have identified an active compromise and extortion campaign attributed to UNC6240 (ShinyHunters) targeting Oracle PeopleSoft application infrastructure. The activity was observed between May 27, 2026, and June 9, 2026 and is consistent with the exploitation of CVE-2026-35273, a critical remote code execution vulnerability (CVSS 9.8) in the Environment Management component. The exploitation of this vulnerability directly aligns wi…

Amazon Cognito 1-Click Open Redirection via OAuth Error Handling Abuse Researchers associated with Tenable have discovered a 1-click open redirection technique in Amazon Cognito that can be triggered by abusing the OAuth error-handling mechanism. The vulnerability stems from AWS's OAuth implementation validation sequence: if validation fails due to an unsupported scope, mismatched PKCE parameters, or an unsupported response type, the error handling processes the failure and automatically issues…
Microsoft Entra ID 1-Click Open Redirection via OAuth Error Handling Abuse Researchers associated with Tenable have discovered new techniques to trigger 1-click open redirection attacks in Microsoft Entra ID by abusing the OAuth error-handling mechanism. The attack relies on an initial setup phase where a threat actor registers an OAuth application in an actor-controlled tenant and configures its redirect_uri to point to an attacker-controlled domain. When a victim clicks on a specifically craf…
Written by: Takahiro Sugiyama, Peter Revelant, Mathew Potaczek Introduction In late 2025, Mandiant responded to a security incident involving a compromised web server running KnowledgeDeliver. KnowledgeDeliver is a Learning Management System (LMS) developed by Digital Knowledge commonly used in Japan. Mandiant identified a critical vulnerability that allowed unauthenticated Remote Code Execution (RCE). An unknown threat actor leveraged this access to inject malicious code into the LMS platform,…
While Russian-speaking threat actors have historically dominated the phishing-as-a-service (PhaaS) landscape, a rival ecosystem is rapidly growing within the Chinese-language underground. Google Threat Intelligence Group (GTIG) analyzed a dozen current PhaaS offerings in the Chinese underground, all of them mature services and many likely tied intricately to the broader criminal ecosystem in that region. These services not only lower the barrier to entry for Chinese cyber criminals, but reveal …
Why Mythos (and other AI models) Make Continuous Exposure Visibility Critical For years, vulnerability discovery was naturally constrained by expertise, time, and scale. Finding meaningful security issues often required experienced researchers spending days or weeks understanding codebases, testing assumptions, reviewing implementations, and validating exploitability. That dynamic is changing rapidly. Recent developments around systems like Anthropic’s Project Glasswing 🔗 and Mythos, OpenAI’s …
Executive Summary Since our February 2026 report on AI-related threat activity, Google Threat Intelligence Group (GTIG) has continued to track a maturing transition from nascent AI-enabled operations to the industrial-scale application of generative models within adversarial workflows. This report, based on insights derived from Mandiant incident response engagements, Gemini, and GTIG’s proactive research, highlights the dual nature of the current threat environment where AI serves as both a so…

Here’s how the most common scams targeting Apple Pay users work and what you can do to stay one step ahead
Modern payment integrations are fast, flexible, and increasingly complex. APIs talk to gateways, webhooks trigger state changes, third parties handle fraud, retries, refunds, and orchestration layers quietly sit in between. In most teams, the signal that things are “working” is simple: transactions go through. That signal is misleading. At RedHunt Labs, we found that the real-world payment pentests reveal the common mistake of treating PCI DSS as a finish line instead of a baseline. This blog r…
Huntress researchers weigh in on the challenge of getting feature parity across Windows, macOS, and Linux. And learn how unique security models and platform maturity shape the way products are built.
Payment gateways are built to move money reliably. Attackers view them as systems built on trust, timing, and assumptions. A gateway that works consistently is not a sign of safety. It is a stable environment to study, probe, and eventually abuse. This blog examines payment gateways from an attacker’s perspective, grounded in real exploitation patterns and reinforced with direct insights from industry experts. These patterns are documented extensively in the RedHunt Labs Payment Gateway Integra…
