Stopping AiTM attacks: The defenses that actually work after authentication succeeds

The security industry has spent years building better authentication. Longer passwords, second factors, hardware tokens. And attackers responded by moving past authentication entirely. Adversary-in-the-middle (AiTM) phishing does not steal credentials and replay them. It sits between the user and the legitimate service, watches a real authentication succeed in real time, and walks away with the…

The issue stems from improper protection of the /mcp_message endpoint,…

Authentication is broken: Here’s how security leaders can actually fix it

Authentication keeps breaking where it matters most: On regulated front lines such as healthcare, government, aerospace and travel. The core issue is not a lack of innovation. Instead, it is a brittle and fragmented ecosystem of cards, readers, middleware and software that rarely work together under real-world pressure. Even today’s “passwordless” solutions can be undermined…

EvilTokens abuses Microsoft device code flow for account takeovers

A new phishing-as-a-service (PhaaS) campaign is abusing Microsoft’s device code authentication flow to gain unauthorized access to user accounts. Sekoia researchers first spotted the toolkit “EvilTokens” that lets attackers capture authentication tokens by tricking users into completing a legitimate login process in Microsoft’s own environment. The activity, observed since at least mid-February, relies on social…

FIRESIDE CHAT: In the AI age, your MFA, authentication apps can be compromised in minutes

The authentication layer that corporate America spent a decade building is now a liability. Listen to the podcast:The day MFA became the problem That’s the blunt assessment of Kevin Surace, chairman of Token, a Rochester, N.Y.-based security company whose biometric hardware is drawing attention from enterprise security teams and federal regulators alike. Surace made the…

Your MFA isn’t broken — it’s being bypassed, and your employees can’t tell the difference

Multi-factor authentication was supposed to be the solution. For years, security teams have told employees that MFA would keep them safe. Password stolen? No problem — attackers still need that second factor. But adversary-in-the-middle (AiTM) phishing has changed everything. These attacks do not try to steal passwords and MFA codes separately. They capture the entire…

CISA warns of actively exploited Ivanti EPM and Cisco SD-WAN flaws

The US Cybersecurity and Infrastructure Security Agency (CISA) has warned that an authentication bypass vulnerability patched in Ivanti Endpoint Manager (EPM) last month is now being exploited in the wild.

AVideo Zero-Click Flaw Lets Attackers Hijack Live Streams

A flaw in the open-source AVideo platform requires no authentication and allows attackers to remotely execute commands and take over affected servers. Exploitation of the vulnerability “… can lead to full server compromise, data exfiltration (e.g., configuration secrets, internal keys, credentials), and service disruption,” said researchers. Inside the AVideo Server Takeover Risk AVideo is an…

Where Multi-Factor Authentication Stops and Credential Abuse Starts

Organizations typically roll out multi-factor authentication (MFA) and assume stolen passwords are no longer enough to access systems. In Windows environments, that assumption is often wrong. Attackers still compromise networks every day using valid credentials. The issue is not MFA itself, but coverage.  Enforced through an identity provider (IdP) such as Microsoft Entra ID, Okta,…

Threat actors weaponize OAuth redirection logic to deliver malware

An ongoing phishing campaign is abusing the OAuth authentication redirection mechanism to avoid triggering conventional email and browser defenses, Microsoft researchers have revealed. The attackers are targeting government and public-sector organizations, and redirecting unsuspecting users from trusted login pages to their own infrastructure, to serve malware or capture login credentials. The attack, from the victim’s…

OAuth phishers make ‘check where the link points’ advice ineffective

Microsoft has warned that phishers are exploiting a built-in behavior of the OAuth authentication protocol to redirect victims to malware, using links that point to legitimate identity provider domains such as Microsoft Entra ID and Google Workspace. The links look safe but ultimately lead somewhere that isn’t. “OAuth includes a legitimate feature that allows identity…
