Re: [Vol-users] Sample error or real module? (and other questions)

Thanks Michael. Regarding the latter part of inspecting the data around the strings, that's where I really need the help. I know I can accomplish that with volshell, but I'm not proficient enough yet to know how to get at it. If you could provide the necessary commands to get at the data around this hit [kernel:f9805ba44800] as an example, that would be most helpful. I'm sure I was doing something n00bishly wrong, but I could never get to the point of displaying the data around that location. I'd be more specific about my attempts, but I'm not in front of my analysis machine right now and don't recall exactly what I tried. thanks, greg I wouldn't think the module at 0x48706657040b0003 requires investigation. Not only bc its not in the 0xfffff8 range, but you might notice legitimate modules are typically loaded at page aligned base addresses (not XXX0003). Your result looks like a false positive and given the way modscan works (pool scanning) its probably a partially overwritten structure in free/deallocated memory. We *could* put a sanity check in the code to suppress entries that aren't loaded at page aligned addresses, but there are a few exceptions where you'll have modules loaded from non-page aligned addresses. For example, we just looked at a rootkit today in class that is loaded at 0x81b91b80 (on a 32-bit system). Jared's advice is also good - if you ever suspect something like this again, you can use volshell to display the data at the alleged base address and see what's there. If its not an MZ signature, then its probably not a currently loaded module (but keep in mind you can overwrite the MZ with 00 or anything else as a trick...but in that case you'll see real executable code not too far away). I would suggest trying to figure out what downloaded the EXE in the first place, so that you can determine what it does after the download finishes (drop to disk and run, drop to disk and run then delete, load directly into memory without touching disk, etc). I would also inspect the data around the strings you found in kernel and free memory - is it verbatim with what you see in the pcap (i.e. just a copy of the packet) or has it been altered (i.e. unpacked, executed, expanded). >>> On 5/14/15 4:31 PM, Gregory Pendergast wrote: Just as a >>> follow up to my last reply, the shimcache plugin reported >>> that there was no shimcache data, and the timeliner plugin >>> didn't reveal anything apparently interesting except IE >>> history related to the download. >>> >>> Thanks, Greg >>> >>> >>> On May 14, 2015, at 12:35 PM, Jared Greenhill >>> &lt;jared703(a)gmail.com <mailto:jared703@gmail.com>> wrote: >>> >>>> Hey Greg, >>>> >>>> A couple thoughts/ideas: >>>> >>>> What was the initial reason for investigation- the suspect >>>> EXE?
