Stay Ahead With Linux Security Features

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...

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,...

Researchers investigating a campaign now tracked as Miasma found that more than 30 packages in Red Hat's @redhat-cloud-services npm namespace had been altered to deliver credential-stealing malware. . The packages weren't being used to deploy ransomware or sabotage systems. From what has been reported so far, the objective appears to have been much simpler: collect credentials from developer environments and use that access elsewhere. GitHub tokens, cloud credentials, SSH keys, and other...

Linux rootkits are old, but they never really disappeared. They just stopped attracting the same attention. . Most malware wants to execute and spread. A rootkit wants to stay invisible long enough that nobody notices the compromise until the damage is already done, and on Linux systems, that still works more often than many teams are comfortable admitting. That difference matters because modern infrastructure runs heavily on Linux underneath. Cloud workloads, ESXi hosts, telecom appliances,...

A production Linux server gets rebuilt from an old image. A contractor leaves. A CI/CD job is retired. Months later, the same SSH public keys are still sitting in authorized_keys, silently trusted by root or a service account nobody owns anymore. . That is how SSH key sprawl usually happens. It rarely stems from one obvious failure. Instead, it accumulates through years of small access decisions that never expire. For attackers, those forgotten keys are not clutter; they represent silent SSH...
