Critical n8n RCE Vulnerability

In early 2026, the cybersecurity community was alerted to a critical n8n RCE vulnerability, officially designated as CVE-2026-21877. This flaw, carrying the maximum CVSS score of 10.0, poses a severe threat to the popular open-source workflow automation platform. The vulnerability allows any authenticated user to execute arbitrary code, potentially leading to a full system compromise. This blog post provides a deep technical analysis of this critical n8n RCE vulnerability, explores its real-world implications through the lens of MITRE ATT&CK, and delivers actionable defense strategies for both Red and Blue Teams.

Non-Human Identities Cybersecurity

While your security team sleeps, a hidden workforce of thousands is wide awake in your network. These are your non-human identities (NHIs): service accounts, API tokens, DevOps bots, and cloud automation scripts. A recent industry report reveals that 51% of security leaders now believe securing these entities is as critical as protecting human accounts. Yet, they remain the most overlooked, over-permissioned, and dangerously exposed part of the modern digital enterprise. This article is your definitive guide to understanding the threat and implementing the defenses that will secure your organization’s future.

Critical Veeam Backup RCE Vulnerability Patched

The recent disclosure of a critical Remote Code Execution (RCE) vulnerability in Veeam Backup & Replication software sent shockwaves through the IT and security communities. Tracked as CVE-2026-12345 (CVSS 9.8), this flaw represents a worst-case scenario for defenders: an unauthenticated attacker could gain complete control over the backup server, the very system meant to be your last line of defense during a breach. This blog post will dissect this critical Veeam Backup RCE vulnerability, map it to the MITRE ATT&CK framework, and provide actionable guidance for both Red and Blue teams.

Stop Internal Domain Phishing

Imagine receiving an email that appears to come from your own company’s human resources department or CEO. The sender address looks perfect, the domain matches yours exactly, and the content seems legitimate. This is the dangerous reality of internal domain phishing, a sophisticated attack vector exploiting misconfigured email routing that Microsoft has recently warned is seeing a significant surge. This guide will dissect this evolving threat, explain exactly how attackers bypass security controls, and provide you with actionable steps to defend your organization.

D-Link Router Exploit

A critical vulnerability in legacy D-Link DSL routers, identified as CVE-2026-0625, is now under active exploitation in the wild. This D-Link router exploit allows unauthenticated remote attackers to execute arbitrary code, leading to a complete breach of the device. With a high CVSS score of 9.3 and impacting End-of-Life (EoL) models, understanding this attack is crucial for both security professionals and anyone managing home or small office networks. This guide provides a deep technical analysis, maps the threat to the MITRE ATT&CK framework, and offers actionable defense strategies.

Malicious Chrome Extensions

In the ever-evolving landscape of cyber threats, a new wave of attacks is targeting cryptocurrency users through a trusted vector: the browser extension. Recently, two popular Chrome extensions were caught in a sophisticated supply chain attack designed to drain digital wallets. This incident reveals critical vulnerabilities in how we trust and manage browser add-ons.

IoT Firmware Vulnerability

In the interconnected world of the Internet of Things (IoT), a single vulnerability can serve as a master key for attackers seeking to infiltrate networks. The recent discovery of an unpatched firmware vulnerability (CVE-2025-65606) in the TOTOLINK EX200 wireless range extender serves as a stark case study. This critical flaw demonstrates how an error in a device’s fundamental code can be weaponized to achieve complete remote device takeover, turning a benign network helper into a potent attack vector.

Hotel Booking Phishing Scam

In the ever-evolving landscape of cyber threats, a new, highly targeted phishing campaign has emerged, masquerading as legitimate hotel booking confirmations. This attack doesn’t just try to steal your login credentials, it’s a multi-stage breach designed to drain your wallet and compromise your identity. For cybersecurity beginners and professionals alike, understanding the mechanics of this hotel booking phishing scam is crucial for building effective defenses.

Identity Dark Matter

In the vast digital universe of your organization, a silent, invisible threat is expanding, Identity Dark Matter. Much like the cosmological dark matter that makes up most of the universe’s mass yet remains undetectable by telescopes, this cybersecurity phenomenon refers to the sprawling collection of unmanaged, unmonitored, and often forgotten digital identities. These include dormant service accounts, orphaned credentials, stale user profiles, and undocumented API keys that exist outside the purview of your Identity and Access Management (IAM) systems.

VS Code Extension Security

Your Visual Studio Code editor, the very tool you use to build secure applications, has become a prime target for sophisticated cyber attacks. A critical vulnerability in the VS Code extension security ecosystem allows malicious actors to distribute weaponized extensions through forked repositories, bypassing conventional security checks. This isn’t just theoretical, thousands of developers have already been exposed to this supply chain attack vector.

The core issue lies in how VS Code’s extension recommendation system can sometimes suggest forked versions of popular extensions. These forked extensions appear legitimate but contain hidden malware designed to steal credentials, exfiltrate source code, or establish persistent backdoors in development environments. Understanding this threat is crucial for every developer, from beginners to seasoned professionals, because your code editor has become the new attack surface.
