Cron Hero Esm H350
Price Tag 1security advisory attack

A Linux server gets cleaned up after an intrusion. The suspicious process is terminated, credentials are rotated, and the system is rebooted during maintenance. Everything seems secure. A few hours later, the same outbound connection appears again. . Situations like that point to persistence . The attacker no longer needs the original exploit because something on the host continues restoring access behind the scenes. Finding that mechanism is often more important than understanding how the...

Siem Architecture Hero Esm H350
Price Tag 1threat detection scalability

Building a SIEM is easier than scaling one. Most open-source deployments start as a simple "all-in-one" server. It is easy to set up, but that design rarely survives the transition from a lab to a production workload. . A SIEM watching 20 endpoints is not doing the same job as one watching 500. More endpoints mean more logs; more logs require more storage; more storage makes search heavier. Eventually, the very architecture that made your lab easy to deploy becomes the reason your production...

Http2 Bomb Hero 2026 Esm H350
Price Tag 1security advisory apache

A newly disclosed attack technique called HTTP/2 Bomb is drawing attention because it targets the software that sits at the front of much of the Linux internet. Apache HTTP Server, NGINX, Envoy, and the ingress layers that many Kubernetes environments depend on can be forced into consuming disproportionate amounts of memory using relatively small amounts of attacker traffic. . For Linux administrators, the concern is not the HTTP/2 protocol itself. It is the possibility that a single...

Supply Chain Risk Starts At The Workstation Hero Esm H350
Price Tag 1security advisory important

The compromise of Nx Console shows how much infrastructure now sits behind a single developer account. GitHub repositories, CI/CD pipelines, container build systems, Terraform projects, Kubernetes deployments. None of those systems was the initial target. The workstation was. . Attackers did not need a Linux privilege escalation bug or a remote code execution chain. They needed developers to trust a tool they were already using. For many organizations, that was enough. What Happened? Federal...

Persistence Tricks Hero Esm H350
Price Tag 1security advisory open-source

You remove the malware. You rotate the compromised credentials. You patch the original vulnerability and close the ticket. Two weeks later, the attacker is back. . What happened? You didn't lose the battle at the exploit; you lost it at the cleanup. In many modern Linux intrusions, the malware you found wasn't the main problem—it was the fallback mechanisms left behind. These hooks quietly restore attacker access the moment you look away. If you clean a host but miss these persistence layers,...

Gian Spicuzza on Social Engineering and Exploiting Business Risks

We are happy to announce a new addition to the Linux Security Contributing Team: Gian G. Spicuzza. Currently a Graduate Student pursuing a Masters Degree in Computer Security (MSIA), Gian is a certified Linux/Unix administrator, the lead developer for the OSCAR-Backup System (at Sourceforge.com) and has experience in a variety of CSO, Management and consulting positions. His first topic is a quick foray into the world and psychology of Social Engineering: All the security in the world isn't going to stop one of your employees or coworkers from giving up information. Just how easy is it? Craig never worked for Linda's company, nor did he call from IT. Craig was an unethical hacker who just gained unauthorized access to her account. Why? Because a phone call is simple. Read on to see just how easy businesses can be exploited. . Social Engineering is not just a definition! By: Gian G. Spicuzza (This email address is being protected from spambots. You need JavaScript enabled to view it.) In modern day, you would assume that brute force hacking coupled with some known software flaws would be the easiest way to circumvent a security system. You . Social Engineering has become a sophisticated form of psychological manipulation, exploiting human behavior rather than just tech vulnerabilities, posing significant risks. Social Engineering, Business Security, User Exploitation. . Anthony Pell
