I just noticed that there are TWO lists of Linux rootkits. Earlier I thought there were only one. One is mostly 2yrs old, the other had an update yesterday.
https://github.com/tkmru/awesome-linux-rootkits
separate from:
https://github.com/milabs/awesome-linux-rootkits
There’s also this list (not Linux-centric):

[None of the above are firmware bootkit-centric, except for the common style of BIOS-centric MBR persistance.]
