A new variation of the ClickFix attack dubbed 'ConsentFix' abuses the Azure CLI OAuth app to hijack Microsoft accounts without the need for a password or to bypass multi-factor authentication (MFA) verifications. [...]
Device code phishing abuses the OAuth device flow — Azure can yield very powerful tokens while Google limits scopes, reducing the blast radius. Register for Huntress Labs' Live Hack to see live Microsoft 365 attack demos, explore defensive tactics, and get an Identity Security Assessment. [...]
Microsoft says it has been enforcing multifactor authentication (MFA) for Azure Portal sign-ins across all tenants since March 2025. [...]
In this type of misconfiguration, cyberattackers could use exposed secrets to authenticate directly via Microsoft’s OAuth 2.0 endpoints and infiltrate Azure cloud environments.
The recent mass-theft of authentication tokens from Salesloft, whose AI chatbot is used by a broad swath of corporate America to convert customer interaction into Salesforce leads, has left many companies racing to invalidate the stolen credentials before hackers can exploit them. Now Google warns the breach goes far beyond access to Salesforce data, noting the hackers responsible also stole valid authentication tokens for hundreds of online services that customers can integrate with Salesloft, including Slack, Google Workspace, Amazon S3, Microsoft Azure, and OpenAI.
Starting in October, Microsoft will enforce multi-factor authentication (MFA) for all Azure resource management actions to protect Azure clients from unauthorized access attempts. [...]
Microsoft Entra ID (formerly Azure Active Directory) is the backbone of modern identity management, enabling secure access to the applications, data, and services your business relies on. As hybrid work and cloud adoption accelerate, Entra ID plays an even more central role — managing authentication, enforcing policy, and connecting users across distributed environments
A proof-of-concept (PoC) attack vector exploits two Azure authentication tokens from within a browser, giving threat actors persistent access to key cloud services, including Microsoft 365 applications.
A proof-of-concept attack called "Cookie-Bite" uses a browser extension to steal browser session cookies from Azure Entra ID to bypass multi-factor authentication (MFA) protections and maintain access to cloud services like Microsoft 365, Outlook, and Teams. [...]
It's sorted out (mostly), but European users had a manic Monday Microsoft's multi-factor authentication (MFA) for Azure and Microsoft 365 (M365) was offline for four hours during Monday's busy start for European subscribers.…
Our research reveals two significant vulnerabilities in Microsoft Azure Private 5G Core (AP5GC). The first vulnerability (CVE-2024-20685) allows a crafted signaling message to crash the control plane, leading to potential service outages. The second (ZDI-CAN-23960) disconnects and replaces attached base stations, disrupting network operations. While these issues are implementation-specific, their exploitation is made possible by a systemic weakness: the lack of mandatory authentication procedures between base stations and packet-cores.
The attack affects organizations that have synced multiple on-premises Active Directory domains to a single Azure tenant.
Starting in July, Microsoft will begin gradually enforcing multi-factor authentication (MFA) for all users signing into Azure to administer resources. [...]
Microsoft will roll out Conditional Access policies requiring multifactor authentication from administrators when signing into Microsoft admin portals such as Microsoft Entra, Microsoft 365, Exchange, and Azure. [...]
Microsoft on Friday said a validation error in its source code allowed for Azure Active Directory (Azure AD) tokens to be forged by a malicious actor known as Storm-0558 using a Microsoft account (MSA) consumer signing key to breach two dozen organizations
The "nOAuth" attack allows cross-platform spoofing and full account takeovers, and enterprises need to remediate the issue immediately, researchers warn.
A security shortcoming in Microsoft Azure Active Directory (AD) Open Authorization (OAuth) process could have been exploited to achieve full account takeover, researchers said
Microsoft has addressed an Azure Active Directory (Azure AD) authentication flaw that could allow threat actors to escalate privileges and potentially fully take over the target's account. [...]
Azure admins are urged to disable shared key access and implement Azure Active Directory authentication.
Two common attacks against on-premises Kerberos authentication servers — known as Pass the Ticket and Silver Ticket — can be used against Microsoft's Azure AD Kerberos, a security firms says.
