Latest cybersecurity reporting from selected sources.

Email attacks overtook exploits as the top ransomware root cause last year. Multifactor authentication (MFA) was deployed in 97% of credential-based attacks but failed to prevent compromise.

Microsoft Threat Intelligence identified threat actor activity with overlapping tradecraft commonly associated with ShinyHunters, including voice phishing (vishing), supply-chain compromise, and misconfigured guest access targeting SaaS-based applications. The post Defending SaaS-based applications against ShinyHunters OAuth abuse appeared first on Microsoft Security Blog.

Datadog Security Labs is warning of "several overlapping campaigns" that are systematically enumerating corporate GitHub organizations, repositories, and user accounts through the GitHub API

The threat actor known as ToddyCat has been attributed to a new malware called Umbrij that's designed to gain surreptitious access to a victim's email correspondence via the Google API

At least four cybersecurity firms confirmed they have been affected by a breach of business intelligence platform Klue via Salesforce integration

In February 2026, a phishing-as-a-service (PhaaS) platform called EvilTokens went live. Within five weeks, it had compromised more than 340 Microsoft 365 organizations across five countries.  The targets of the platform received a message asking them to enter a short code at microsoft.com/devicelogin and complete their normal MFA challenge, then walked away believing they had verified a

Cisco is warning that a critical Catalyst SD-WAN Controller authentication bypass flaw, tracked as CVE-2026-20182, was actively exploited in zero-day attacks that allowed attackers to gain administrative privileges on compromised devices. [...]

A threat actor named Mr_Rot13 has been attributed to the exploitation of a recently disclosed critical cPanel flaw to deploy a backdoor codenamed Filemanager on compromised environments

Multiple official SAP npm packages were compromised in what is believed to be a TeamPCP supply-chain attack to steal credentials and authentication tokens from developers' systems. [...]

A single third-party OAuth integration can become a direct path into your environment. Push explains how the Vercel breach shows a compromised OAuth app can lead to widespread impact across downstream customers. [...]

Attacker First Compromised AI Tool Used by Vercel Employee, Platform Provider FindsCloud platform provider Vercel said an attacker breached its systems and stole customer data after compromising a third-party agentic artificial intelligence tool used by an employee, called Context.ai, and stealing from it credentials and OAuth tokens tied to multiple services and customers.

Blames outfit called Context.ai, which reckons an agentic OAuth tangle caused the incident Vercel, the company that created the open source Next.js web development framework, has a data leak that led to compromise of some customer credentials, and blamed an outfit called Context.ai for the mess.…

An OAuth supply chain compromise at Vercel exposed how trusted third party apps and platform environment variables can bypass traditional defenses and amplify blast radius. This article examines the attack chain, underlying design tradeoffs, and what it reveals about modern PaaS and software supply chain risk.

In 2024, compromised service accounts and forgotten API keys were behind 68% of cloud breaches. Not phishing. Not weak passwords. Unmanaged non-human identities that nobody was watching

Cisco has released updates to address a critical security flaw in the Integrated Management Controller (IMC) that, if successfully exploited, could allow an unauthenticated, remote attacker to bypass authentication and gain access to the system with elevated privileges

CISA published an advisory on endpoint management hardening after the Stryker wipe. Their Multi Admin Approval recommendation is a speed bump, not a wall. Here is what actually stops a Global Admin compromise: no standing privileges, PIM with Authentication Context, FIDO2 hardware keys, and automated session revocation.

The critical vulnerability affecting both cloud and self-hosted n8n instances requires no authentication or even n8n account to be exploited

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, or

Cisco is warning that a critical authentication bypass vulnerability in Cisco Catalyst SD-WAN, tracked as CVE-2026-20127, was actively exploited in zero-day attacks that allowed remote attackers to compromise controllers and add malicious rogue peers to targeted networks. [...]

Stolen tokens and compromised devices let attackers reuse trust without breaking authentication. Specops Software explains why identity alone isn't enough and how continuous device verification strengthens Zero Trust. [...]
