Quick Malware Analysis: ICEDID BOKBOT infection pcap from 2023-07-25

Thanks to Brad Duncan for sharing this pcap from 2023-07-25 on his malware traffic analysis site! Google currently has a warning for the site, so we're not including the actual hyperlink but it should be easy to find.

We did a quick analysis of this pcap on the NEW Security Onion 2.4. If you'd like to follow along, you can do the following:

• install Security Onion 2.4 in a VM:
  https://docs.securityonion.net/en/2.4/first-time-users.html
• import the pcap using so-import-pcap:

• optionally enable the new DNS lookups feature:

Screenshots

First, we start with the overview of all alerts and logs:

Next, let's focus on just the alerts:

Let's look at the Win32/IcedID Request alerts:

Both of these alerts are for the same TCP stream, so let's take a look at the full packet capture for that stream:

Now let's switch to the ASCII transcript:

Next, let's review all of the protocol metadata:

Let's begin our tour of the protocol metadata with HTTP:

One of these HTTP transactions is a 302 redirect:

Next let's review DNS lookups:

Next let's look at SSL logs:

Notice that there's an interesting organization name of "Stark Industries Solutions Ltd" with 2 interesting domain names:

If we switch to Zeek Notices we see that the Stark Industries certificates were self-signed:

Here's an overview of all connections:

If we sort those connections by client.ip_bytes, we will find one client connection that transferred much more data than the others:

We can then drill into that connection:

Pivoting to PCAP, we see evidence that this is VNC:

We can then download the PCAP and open it in NetworkMiner (included in Security Onion Desktop). The Images tab shows what was transferred via VNC:

We can then open those images to get a sense of what was happening via VNC:

Back in NetworkMiner, we can go to the Parameters tab and see the keystrokes for amazon.com being sent over VNC:

Security Onion 2.4.40 Sneak Peek!

We recently concluded our 2.4 Feature o' the Day series:

https://blog.securityonion.net/search/label/feature%20o%27%20the%20day

That series did not include every new feature in 2.4 and there are more waiting for you to discover in the current 2.4.30 version. Additionally, there are even more new features coming in future versions!

Security Onion 2.4.40 is coming soon and one of the new features is an updated version of SOC Grid with even more visibility into the health of your deployment. You can click the picture to see a larger version.

Compared to previous versions, there are new fields on the top row that show things like memory, storage, CPU, and network usage. In addition to those new metrics, when you expand the row and look at the Node Status section on the left it now includes additional metrics and visualizations.

You can read more about SOC Grid in our documentation:
