Mark, Between you and I (& the rest of the list) I used CyberCop a few years back and cut off an entire network. Not, as you'd imagine, through testing for DOS vulnerabilities but the shear weight of the traffic. Learned a lot that day! Also prompted me to create the distributed scanners page. If I remember correctly many of the Cybercop scans contain the word "cybercop" in the data of the packet allowing easy detection. I'm trying to think of an IDS that doesn't detect it and can't take care -andy shame about the beer!

Andy, Yes, it if one got it to network map properly after a scan. The issue with CyberCop Scanner 5.0, that is VERY VERY NOISY. It left little tidbits all over the network that a network scan was being conducted. Some network based ids and firewalls would pick up some of the CyberCop fingerprints but not all. Even the Sn0rt signature only picks one or two CyberCop fingerprints. To answer your question, yes CyberCop used active fingerprinting /mark -----Original Message----- From: Andy Cuff [Talisker] [mailto:lists () securitywizardry com] Sent: Sunday, November 23, 2003 6:49 AM To: Teicher, Mark (Mark); Ron Gula; focus-ids () securityfocus com Cc: Seanor, Joseph (Joe) Subject: Re: Passive OS Fingerprinting was Cisco CTR etc Mark, Correct me if I'm wrong but didn't Cybercop use active fingerprinting to generate the 3D model not passive? -andy Talisker Security Tools Directory http://www.securitywizardry.com ----- Original Message ----- From: "Teicher, Mark (Mark)" <teicher () avaya com> To: "Andy Cuff [Talisker]" <talisker () securitywizardry com>; "Ron Gula" <rgula () tenablesecurity com>; <focus-ids () securityfocus com> Cc: "Seanor, Joseph (Joe)" <jseanor () avaya com> Sent: Sunday, November 23, 2003 1:13 PM Subject: RE: Passive OS Fingerprinting was Cisco CTR etc Not quite sure if they are ahead of the curve or just taking advertising a feature many people didn't realize was a possibility of the various Enterprise Management Systems available. Cabletron Spectrum had a network mapping feature based on ttl's a long time ago. Very few people even deployed Cabletron Spectrum. The other was ANMS (Automatic Network Monitoring System) a bash, perl, ksh scripting network architecture that is still or was used by many large telecommunications carriers. A most recent attempt at network mapping was the 3-d mapping option in Cybercop 5.0 Although not as nifty as the comet tail network mapping RNA offers. :) I will be in the southeast quadrant of the country that week. /m -----Original Message----- From: Andy Cuff [Talisker] [mailto:talisker () securitywizardry com] Sent: Saturday, November 22, 2003 3:10 AM To: Teicher, Mark (Mark); Ron Gula; focus-ids () securityfocus com Subject: Re: Passive OS Fingerprinting was Cisco CTR etc Hey Mark, LTNS ! I was under the impression that anti-sniff was (thinking of a polite word) prone to false positives. Furthermore, I'd be tempted to deploy a passive OS fingerprinting tool on a Data In Nothing Out (DINO) tap, this would make the detection of the pf tool even more difficult through such measures. I think most IDS vendors are developing such technology (with one almost definite exception) But as usual Ron and Marty are ahead of the drag curve. I think it's really s3xy but as my wife will testify I'm sad and I need a life ;o) So s3xy that I have included a page detailing them all at http://www.securitywizardry.com/osfp.htm P0f Ettercap ARCHAEOPTERYX RNA NEVO Prelude pfprintd Disco There was one that was a predecessor I think to P0f but it is no longer supported so I left it out cheers Mark Are you anywhere near DC 11/12 Dec for a beer? -andy cuff Talisker Security Tools Directory http://www.securitywizardry.com ----- Original Message ----- From: "Teicher, Mark (Mark)" <teicher () avaya com> To: "Ron Gula" <rgula () tenablesecurity com>; <focus-ids () securityfocus com> Sent: Thursday, November 20, 2003 7:49 PM Subject: RE: NeVO Scan Application was RE: Cisco CTRRon, Didn't @Stake produce AntiSniff to detect passive type monitoring applications ?? /mark -----Original Message----- From: Ron Gula [mailto:rgula () tenablesecurity com] Sent: Thursday, November 20, 2003 12:45 PM To: Teicher, Mark (Mark); focus-ids () securityfocus com Subject: Re: NeVO Scan Application was RE: Cisco CTR Woah ... no-one should be able to detect NeVO or RNA (or a NIDS) just by sitting there. You need to do real complex things invoking timing and other checks to find hosts that are passively listening. Desktop agents like Sygate will see scans from Nessus, Nmap, pings, etc. but they will have a hard time detecting passive analysis of their network traffic.

Wondering if the Enterprise/Desktop firewall products can detect NeVO scans as they can nmap scans. It will be very interesting to see how Desktop firewalls in the corporate environmentstand up to NeVO scans.. Something to try in the lab against all those Enterprise/Desktop Firewall products.. :) /mark -----Original Message----- From: Ron Gula [mailto:rgula () tenablesecurity com] Sent: Thursday, November 20, 2003 7:38 AM To: focus-ids () securityfocus com Subject: Re: Cisco CTR At 04:54 AM 11/20/2003 -0700, Mark Teicher wrote:Just curious on how NeVO compares to Intrusec Expose ??I have not seen Expose recently, but my thought was that it was a continuous low-volume active scan that could launch other vulnerabilityscanners when change was detected. NeVO does the same sort of thing, but passively through network packet/session monitoring. Besides looking for change in the network, it also looks for the vulnerability.NeVO needs to wait for a packet to be sent before it sees a host, port,client, server or vulnerability. If folks deploy NeVO with a Lightning Console, they can launch distributed Nessus scans if they see a system or a vulnerability data that they would like to follow up with an active scan.
