Hi all, I need to install an anti-rootkid in a lot of servers. I know that there're several options: tripwire, aide, chkrootkit... ?What do you prefer? Obviously, I have to define my needs: - easy setup and configuration - actively developed -- Thanks, Jordi Espasa Clofent

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,

Hi, I have a 4.9-STABLE FreeBSD box apparently hacked! Yesterday I ran chkrootkit-0.41 and I don't like some of the outputs. Those are: chfn ... INFECTED chsh ... INFECTED date ... INFECTED ls ... INFECTED ps ... INFECTED But all the rest is NOT PROMISC, NOT INFECTED, NOTHING FOUND, NOTHING DELETED, or NOTHING DETECTED. I know by the FreeBSD-Security archives that

Hello, when one has physical access to a computer, he can run something like tripwire, with keys and checksum on a separate, write-only media, to verify the integrity of the system. What if the system is a remote one (in my case Centos 4.3 on a User Mode Linux VPS some hundred of KMs from here)? Does it still make sense to run tripwire remotely? If yes, how, since you cannot plug a floppy or

Hello guys, Whats is the best way to identify a possible user using a botnet with php in the server? And if he is using GET commands for example in other server. Does apache logs outbound conections ? If it is using a file that is not malicious the clam av would not identify. Thanks

Hello, I would like to ask for some specialist assistance in dissecting a 'rootkit' (seems to be massmailing specific,crafted somehow from another kit perhaps) It was found running on 5.x machines belonging (sofar) to my knowledge, 2 companies,one of wich was an isp and another a webhosting service running bsd. I will provide the kit and further details as soon as i am sure the thing will

Hi, there is a remote (VPS) Centos 4.2 server which *may* have been compromised. Reinstalling everything from scratch isn't a problem, it may even be an occasion to improve a few things, the question is another. There are backups of necessary shell script, ASCII configuration files and more or less important email (maildir format, if it matters) including messages with binary attachments in

Another alternative is to use a FIMS/HIDS such as Aide (Advanced Intrusion Detection Environment), OSSEC or Samhain. Be prepared to learn a lot about what your OS normally does behind the scenes (and thus a fair amount of initial fine tuning to exclude those things). Aide seems to work well (I've seen only one odd result) and is quite granular. However, it is local system based rather than

I think Jim (the other one) is doing a marvellous job with extras and plus but he needs to expand the size of his tent. A sensible package policy in extras/plus repo will mean fewer temptations to install 3rd party repo's that can break your system. Some of the packages i would like to see are :- - MySQL 5 rpms - php 5 rpms (already provided) - Open Office 2.0 rpms - webmin - rkhunter -

Morning, I am going to treat this as a rooted box and reinstall from scratch, but any thoughts appreciated: This is a Trixbox Server based on Centos, running kernel 2.6.18-53.1.4.el5 SMP The phone system stopped working but this was traced to a configuration error with a replacement switch (it did not get added to the vlan properly), which meant that Trixbox could not see any DNS servers and

Hi All, Yes, I know, it's really really embarrassing to have to ask but I'm being pushed to the wall with PCI DSS Compliance procedure (http://en.wikipedia.org/wiki/PCI_DSS) and have to either justify why we don't need to install an anti-virus or find an anti-virus to run on our CentOS 5 servers. Whatever I do - it needs to be convincing enough to make the PCI compliance guy tick the

hello, i have a FreeBSD 4.8-PRERELEASE #0 that i use as a gateway / nat box for my home. It also acts as a dns / mail server to the outside world. I'm using ipf and basically filter for bogus networks on the way in and out. I allow everything out keeping state, and allow this in: pass in proto icmp from any to any icmp-type squench group 200 pass in proto icmp from any to any icmp-type timex

Hiya, Currently running Centos 4.2 x86_64 dist on a dual 3G xeon, 2G ram, scsi setupand everythings been running fine on it for some time.

Hi, One of our AWS machines was used in an DOS attack last night and I am looking for possible attack vectors. AWS tells me it was sending UDP port 0 traffic to a cloudflare address. This instance had an incorrectly configured AWS security group exposing all ports. The server in question is a Centos 7 based FreeIPA server, OpenVPN concentrator and DNS server. With a brief inspection before the

Good evening, I was finish the FreeBSD4.9 installation from CD, and only do some edit with the /etc/rc.firewall, /etc/rc.conf, /boot/defaults/loader.conf, and recompiling the kernel to support my ext2 backup harddisk, with sndcard support too. This's a old laptop (ibm380z), i have chkrootkit warning after all finished, i attached my uname -a, dmesg, pkg_info and chkrootkit result, please

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.

Also has filled in scripts for flud and spam and "vadim script" in "/tmp". I has made it noexec. Recently has found out the same process. May be i have left again /tmp opened, or other hole may
