Does anyone know what the "lockr" command is? I can't find any references to it besides people saying they observed malware trying to run it, usually (as is the case here) right after a chattr command with the same arguments.
I think that's something totally unrelated that just happens to have the same name. I don't see anything in their docs that even hints at a UNIX command called "lockr", let alone one that makes sense to call like that.
