Node-RED authentication hole being exploited in the wild

Months after Siemens released fixes for an authentication hole in flow-based programming tool Node-RED, it remains unpatched by many users and attackers are taking advantage of it in the wild. The problem involves open source IoT/IIoT systems, including those embedded in critical infrastructure, deployed outside the control of CISOs and CIOs. Security firm VulnCheck discovered the exploits and disclosed details in a…

What AI-generated malware looks like under the microscope

In this Help Net Security interview, Lindsay Kaye, VP of Threat Intelligence at HUMAN Security, talks about what AI-generated malware looks like on the bench. She points to tidy comments, uniform logging messages, and emojis as signs a script came from a model, and notes that decompiled code strips much of that away. Kaye also covers how AI is squeezing the time teams have to patch, where it helps criminals scale fra…

Ghostunnel: Open-source TLS proxy with mutual authentication

Ghostunnel is an open-source proxy that handles TLS for programs that cannot handle it themselves. It works in two directions. In server mode it sits in front of a backend, accepts TLS connections, checks the client’s certificate, then passes traffic to the service behind it over TCP or a UNIX socket. In client mode it does the reverse, listening for plain local connections, wrapping them in TLS and presenting a clie…

Secure your containers without breaking what works

Container security has a familiar problem. Teams identify vulnerabilities, but turning those findings into lower risk is much harder. A standard container image may include operating-system packages, development tools, debugging utilities and libraries that an application never uses. Each unnecessary component can expand the attack surface and add vulnerabilities to investigate, patch or explain during an audit. Cons…
