email security Linux server 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...

Security Vulnerabilities cisa kev vulnerability prioritization
cisa kev vulnerability prioritization 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...

security advisory vulnerability 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...

Today, Git servers are responsible for deployment pipelines, API tokens, SSH keys, package repositories, and the automation scripts that push code directly.

That makes them trusted systems within the development environment and attractive targets for attackers looking to move...

data privacy automation 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...

The Flint Hills School, a prep academy in Oakton, Va., might seem an unlikely place to find an Internet spammer.

The Flint Hills School, a prep academy in Oakton, Va., might seem an unlikely place to find an Internet spammer. But late last year, technicians at America Online were able to trace the origin of a new torrent of spam, or unsolicited e-mail advertisements, to the school's computer network . On further investigation, though, AOL determined that the spammers were not enterprising students or moonlighting teachers. Instead, a spam-flinging hacker -- who still has not been found -- had exploited a software vulnerability to use the school's computers to relay spam while hiding the e-mail's true origins. It was not an isolated incident. As spam has proliferated -- and with it the attempts by big Internet providers to block messages sent from the addresses of known spammers -- many mass e-mailers have become more clever in avoiding the blockades by aggressively bouncing messages off the computers of unaware third parties.

According to operators of spam-filtering lists, an alarming number of people are unwittingly helping junk mailers shuttle spam, or unsolicited bulk e-mail. Those unassuming victims are running software meant to allow multiple connections over a LAN (local area network) to the Internet through a single line, or what's known as proxy servers. Are you unwittingly helping junk mailers shuttle unsolicited bulk e-mail? Spammers are discovering tricks to tap into proxy servers to send junk mail--with little trace. The problem has grown so quickly that some blocklist owners estimate that between 30 percent and 80 percent of the spam attacks today are caused by open proxies.
