You've probably trained your team to look for red flags. Odd sender names, urgent language, mismatched links. But a well-crafted spoofed email won't trip any of those wires. It looks legitimate, sounds legitimate, and often comes from a domain that passes every automated check you throw at it. . Attackers know exactly how humans scan an inbox. They design around it. This guide walks you through the techniques attackers use to slip a spoofed email past both your filters and your users and what...

Most Linux teams don't struggle to find vulnerabilities anymore. They struggle to decide which ones deserve attention first. Between daily scanner results, vendor advisories, and hundreds of new CVEs each month, the challenge isn't visibility—it's prioritization. . To solve this, organizations typically lean on the National Vulnerability Database (NVD) and CISA’s Known Exploited Vulnerabilities Catalog. But these aren’t competing lists. They answer two entirely different questions. While the...

GNOME is officially shortening its standard vulnerability disclosure window from 90 days to 30 days, a change that impacts upstream maintainers, downstream Linux distributions, and system administrators in how they handle software vulnerabilities. The policy shift, announced by long-time security coordinator Michael Catanzaro , addresses modern software patching realities and a growing influx of automated submissions. . Because GNOME is the default desktop environment on several major Linux...

For organizations that run a self-hosted Git platform, it’s no longer just about hosting static code repositories. Today, Git servers are responsible for deployment pipelines, API tokens, SSH keys, package repositories, and the automation scripts that push code directly. Confirm that the upgrade addresses known vulnerabilities but also provides production environments. . That makes them trusted systems within the development environment and attractive targets for attackers looking to move...

Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes. The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

SSH Man-In-The-Middle Challenge Recap: Solution and Insights

Two weeks ago, I challenged you to figure out how a machine was compromised. Let me quickly recap the situation. I suspected that someone was using an SSH man-in-the-middle package on the local network. Both sshmitm (part of Dug Song's dsniff[1] package) and ettercap[2] can fill this role. (As it turns out, the culprit was a modified version of sshmitm, so I'll just call it by name henceforward.) The machine running sshmitm needs to be situated between the ssh client and ssh server. When the client machine connects to the server, the machine running sshmitm intercepts the packets. The sshmitm process pretends to be the actual server. It will follow the SSH protocol specification, providing the host key, agreeing on cryptographic algorithms and keys, and eventually asking the client for the password. The sshmitm program establishes a connection to the actual server, as if it's a normal ssh client. It takes the data that it receives from the real client, which it has available in cleartext, and re-encrypts it to the real ssh server as appropriate. The link for this article located at IT World is no longer available. . We faced a serious SSH man-in-the-middle challenge that exposed our network vulnerabilities, prompting immediate enhancements in security measures and staff training.
