Exfiltrate files using the DNS
🗣w8rbt

In reality, how would this be protected against? I'm still nub when it comes to the net sec side of this business. Would using a limited private recursive server that prevented lookups for any but a whitelist be the most secure? Not all DNS servers will respond with the complete zone file to allow for the recursive server to do the lookup so that doesn't seem like a viable option.

So as long as enclave rule sets are defined specifically to only allow the DNS port to appropriate upstream DNS, this would fail.

Complete Malware Analysis VM Image
Complete Malware Analysis VM Image

is there a complate malware analysis vm image that contains most of the decompilers, PE analysers, debuggers, monitoring tools, etc..

thanks!!

p.s. i know that there is flare VM that is free to install but it seems not complete.
🗣darkalimdor18

There’s no “complete” and “most perfect” image, new tools and plugins are published every day and no one can keep up with them all.
You should be able to customize your own image based on your own needs and most importantly skills, there’s no need to downloaded tons of tools and you barely know anything about most of them.
👤MO12400

I would do two things: install something like Remnux and use it as a “wall”. Then install something like Flare to start learning what you like. Eventually either tweak it to your liking, or build an image with your own stuff. Knowing how to install it and configure it is invaluable knowledge. Plus you can then learn other apps to auto-build VMs of your choice with customizations you need for types of malware you are analyzing.

Route all traffic through Remnux. You can then drop traffic outbound but still capture traffic, use Burpe Suite and other tools to dynamically identify C2 and communications safely.
👤FlaccidKraken

Yeah I second REMnux, it’s native Linux but there’s also a Windows version if you can find someone who has taken the GREM. The Windows one is called REMnux Workstation.

This list has to be taken with a huge grain of salt as researcher sometimes try to paint themselves in a much nicer way that what really happened. The Skytech entry is a pretty example of this as I know a little bit the inside of it. The "researcher" received threat from the company not because he disclosed a vulnerability, but because he DoSed the company system from the Dawson network connection. The fact that he disclosed a vulnerability before had nothing to do with the threat he received. Also a lot of the threat he received where not from Skytech, but from Dawson. The reason ? He continued to "test" the school internal system (that didn't belong to Skytech) after being told to stop.

ATT SMS record analysis
I've been asked to provide some analysis of SMS records which were subpoenaed from the carrier but am having a little trouble resolving a few things. There are several messages from a two digit phone number and several instances where two or three messages were sent by the phone at the exact same time (down to the second). It appears to me that the messages sent at the same time were likely long messages broken up into 2 or 3 messages due to character limits, but I can't really come up with anything that would allow a two digit phone number to deliver messages. Any help would be greatly appreciated.
🗣kstewart0x00

I often find that those records reflect carrier services, like paying a bill, checking data plan current usage, and messages regarding the account.

If you received this data in a subpoena return, there should be a document explaining these numbers. When in doubt, I usually call the division that supplied the records.
👤chilledquesadilla

Could they be something that came from AT&T?

Is it from a service? or is it a conversation?

Here's someone asking AT&T the same question about messages on their bill. And AT&T providing stellar customer service, too.
