Aaron, While I don't recall seeing this scan recently, it comes as no surprise. Networked printers are rather ubiquitous and are usually passed off as being secure because it's just a device that prints and nothing more. However, this false sense of security is particularly bad as a lot of printers these days have multiple services running some of which are most likely exploitable. The SNMP scan that you saw would be typical of an attacker looking for internet facing printers with default strings in order to reconfigure the printer at their will. The possibility for malicious activity if they garner remote access passwords then follows - setting up a sniffer, using the printer as an attack point, mapping an internal network, running a warez site (yes, they have ide/scsi drives). Maybe someone should set up a printer honeypot ;) HTH, Chris On Tue, Jun 17, 2003 at 05:49:19PM -0700, Aaron Cheek wrote: > All, > > One of my class Cs got SNMP scanned, and wanted to ask > you what the purpose of this scan you think it might > be: > > 80.200.243.104.1152 > mynet.161: GetRequest(25) > .1.3.6.1.4.1.641[|snmp] > > (Apparently an ADSL user at Belgium - > 104.243-200-80.adsl-fix.skynet.be) > > They tried different OIDs: .1.3.6.1.4.1.641 (Lexmark > International), .1.3.6.1.4.1.11.2 (Hewlett Packard), > .1.3.6.1.4.1.480 (QMS, Inc.), .1.3.6.1.2.1.43 (3Com). > > All scans had src port 1152. > > What I see in common here is printers.
