Here’s a Simple Script to Detect the Stealthy Nation-State BPFDoor

In this blog, the Qualys Research Team explains the mechanics of a Linux malware variant named BPFdoor. We then demonstrate the efficacy of Qualys Custom Assessment and Remediation to detect it, and Qualys Multi-Vector EDR to protect against it. BPFDoor is a Linux/Unix backdoor that allows threat...
