    Mandrake 9 & Snort Log record

    Jan 15 19:53:26 linuxalien snort[1782]: [1:1390:3] SHELLCODE x86 inc ebx NOOP [Classification: Executable code was detected] [Priority: 1]: {TCP} 199.105.112.210:25555 -> 192.168.1.42:32899



    I found the above in my log. I'm a newbie, and I'm wondering if that means someone planted code in my Linux box or not. If so, can I get rid of it or do I re-install? I've got a shore firewall running and also a linksys cable/dsl router with an update already installed. Thanks for any help.

    Snort has detected shell code, that doesn't mean it's been planted. It depends on whether the application running on 192.168.1.42 port 32899 was vulnerable to the attack. In fact, it might not be an attack at all, it could be someone downloading an exploit itself (from port 32899)

    Because it's a high port number it's probably either an outgoing connection, a p2p program (these create a zillion IDS false alarms because of their promiscuity), or a connection that has been NAT'd to a high port number.
