Rapid7 tracked a set of Linux samples that blend into the software and device conventions of the telecom environments they target. The set spans a newly observed BPFDoor variant, a BPF Rekoobe build seen against South Korean targets, a dropper, and six builds of a Linux implant Rapid7 researchers track as AVERAT, deployed against Taiwanese appliances. Additionally, researchers provide source code details of the Rapid7 BPFDoor controller introduced in our April 2026 blog, Stealthy BPFDoor Variants are a Needle That Looks Like Hay.
The chain uses two binaries. A dropper writes a shell script to the appliance’s storage mount and executes it. The script stages both payloads into /sbin under the names ntpdate and udevds, launches them, and deletes each file ten seconds later while the processes continue running. One of those payloads is the dropper itself, re-executing as a resident watchdog, leaving both processes running without an on-disk image.
