Has anyone else seen chkrootkit (version 0.43) on 4.10-prerelease or later report chfn, chsh, and date as infected? I built world yesterday, and my nightly chkrootkit reports this on run. I've replaced the binaries with their 4.9 equivalents, and things don't report as infected. I upgrade the 4.9 machine to 4.10, and chkrootkit reports them as infected again. Is this similar to the

I ran chkrootkit ( v. chkrootkit-0.43 ) earlier and noticed that chfn, date, and chsh showed as being infected. I remember reading post from the past that right now chkrootkit is giving alot of false positives, so I suspected that these 3 binaries are not bad. However, to be on the safe side, I deleted the 3 binaries, removed /usr/src and did a 'make world' to 4.10-STABLE. But, chfn,

This morning, I noticed in my security email, that my entire /usr/bin directory had setuid diff's set on them. I think I've been hacked. So I installed chkrootkit from ports and ran it. It showed not infected for everything, except NETSTAT. NETSTAT showed infected... I ran chkrootkit for another machine (at my office), and it showed not infected for everything. Both machines are

Hello; I'm running a FreeBSD 4.10-release-p2 box and both chkrootkit 0.44 & 0.45 report that my /sbin/init file is infected. It appears as though the egrep for "UPX" in the output of "strings" triggers the infected notice. When I copy the init file from an uninfected box to this one chkrootkit continues to report it as infected. Is chkrootkit reading a copy of the

I run chkrootkit daily. For the first time I've got reports of a problem - Checking `bindshell'... INFECTED (PORTS: 1008) The page http://fatpenguinblog.com/scott-rippee/checking-bindshell-infected- ports-1008/ suggests that this might be a false positive, so I ran 'netstat - tanup' but unlike the report, it wasn't famd on the port. It was tcp 0 0 0.0.0.0:1008

Hey all, I've submitted a fix for chkrootkit port, to solve the false positives on FreeBSD 5 and higher: http://www.freebsd.org/cgi/query-pr.cgi?pr=55919 The topic, btw, should be "Teach security/chkrootkit about FreeBSD 5", but it's not my first typo today. Maintainer, please approve. Authors, please see if you can include the changes. I also fixed a minor bug in chk_vdir.

Hello, last night, my chkrootkit crontab returned an alarm message : > Checking `lkm'... You have 1 process hidden for readdir command > You have 2 process hidden for ps command > Warning: Possible LKM Trojan installed Some research on google make me think it's probably a false positive.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Ok...did some checking. I forgot to mention that I killed dead syslogd. Not just a -HUP but an actual kill and restarted. I did this several times. I was trying to get something else to work. Anyway, I killed it again this morning and restarted. The infect message went away immediately. Could this have been the problem? -
