Thanks Matt! You're right, the one version we have isn't good, but the second version does fit the traffic, so it'll fire. Appreciate the tweak, new version out shortly. Matt On Feb 10, 2011, at 3:27 PM, Matt Olney wrote:
Hey ET folks who are here... If you guys could pass on this information: The rules provided won't fire on Night Dragon C&C traffic.. The offset:66 is calculated from the beginning of the Layer 2 portion of the packet. The data portion (what Snort looks at) starts at offset 54. The correct offset for the rule should be 12. Also, you probably want to add a depth: qualifier of 3 bytes so you don't false positive further down the packet. Don't normally check in on you guys, but this was important enough to check.
