Re: [cobalt-security] chkrootkit LKM Detection?



Try "chkrootkit -x lkm", it will list the "hidden process" ... Sometimes
depending on CPU and disk load, chkrootkit on our racks lists even
"sendmail", "inet" and many other usual system process as hidden ... The
"chkproc" program compares the "ps" output with the "/proc" contents, so If
the process ends before the program finish the checking routine it can list
the process as hidden or suspicious ... hope this helps ...
