Attackers are turning exposed Node-RED instances into a Linux botnet - and the flaw is old enough that most scans miss it.

Node-RED's flow editor ships with a default admin password in many installs, and an exposed dashboard lets attackers inject flows that run shell commands. Once inside, they drop miners and pivot across the network. Change the default credential, bind the editor to localhost, and put it behind authentication.

Most small businesses treat the NIST framework as enterprise paperwork. It is not - the same five functions map onto a ten-person team.

Identify what you actually have, protect the few things that matter, detect the anomalies you can afford to watch, respond with a plan you have rehearsed, and recover from backups you have tested.

Apple's CVE-2024-27834 is in CISA's KEV catalog - which means it is not a theoretical flaw, it is one attackers are actively using.

The bug lets a malicious app bypass TCC protections and reach sensitive data without a prompt. The fix landed in iOS 17.5.1, iPadOS 17.5.1 and macOS Sonoma 14.5.1.

If any device in your fleet is still below those versions, the patch window has long since closed.

A 100-character password can still fall fast if the implementation behind it is wrong — length is not the same as strength.

The musl Linux brute-force-to-root attack shows how a password-handling flaw can undo what a long password promises. Once an attacker reaches the brute-force stage, the bounds are set by how the system stores and checks credentials, not by the character count. Patching the implementation matters more than adding one more character.

Kali Linux turns an ordinary laptop into a full security testing lab — and you do not need a second machine to run it.

Two paths work well: a virtual machine for safe, isolated practice, or dual-boot when you need direct hardware access for wireless and GPU-heavy work. Whichever you pick, start from a verified ISO, use an encrypted persistent volume and take snapshots so a broken experiment costs minutes, not a reinstall.

A remote code execution flaw in the Linux kernel TCP stack turns the network layer itself into the attack surface.

CVE-2026-98432 shows why kernel patching cannot wait for the next maintenance window - the exploit path runs through normal TCP traffic, so an exposed server can be reached without a malicious download.

AI just found 81 flaws in Firefox - a codebase that has been hardened for over two decades.

The count is not the story. Mature, heavily audited software still carried that much undiscovered risk, which says more about how hard vulnerability discovery is than about Firefox itself. AI is turning it from scarce human expertise into something closer to a commodity - and defenders get that leverage too.

India's ports handle most of the country's trade, and much of that infrastructure was never designed to be networked.

Operational technology in ports runs on long-life legacy systems, so patching is slow and exposure stays high. Segmenting IT from OT, and monitoring the boundary between them, is where the leverage is.

Stolen Entra ID credentials reveal who can reach what. Stolen Azure DevOps credentials let attackers change what gets deployed.

The dangerous accounts hold both - Global Admin rights in Entra ID plus write access to a build pipeline. An attacker can edit a YAML file, add a step that pulls malware, and let the trusted CI/CD process deliver it.

Zero Trust breaks the chain: Conditional Access, Just-In-Time admin access, and managed identities over stored secrets.
