THEAD: were the DNC emails taken from an AppRiver server?

This is a follow up to this post, where we noticed that the DNC was running two/more realtime backups of their Exchange server.

We suggested that a backup server was the source of the DNC emails.
The plot thickens.

Forensicator noticed that incoming DNC emails were filtered by AppRiver.

This leads to the question, did AppRiver do more than filter spam from incoming emails?

We think the answer might be: Yes, AppRiver hosted the DNC's email system, or provided backup to it.

We must first consider that it is a lot of work to run a redundant, reliable Exchange server. It probably requires six servers in two sets distributed at different locations in the US.

We think that is out of scope for the DNC and think that they turned to APpRiver for help.
Here, we learn that AppRiver was acquired in 2019.


Launched in 2002, Florida-based AppRiver is a private company which provides subscription-based email and Internet security services.zdnet.com/article/zix-ac…
We also learn:

"These [services] include spam and virus filter systems, email encryption, secure archiving, and secure Microsoft Exchange hosting."

We think the DNC likely used AppRiver's Exchange hosting service.
That means the DNC emails found on Wikileaks were taken from a server managed by a completely separate company.

No wonder Shawn Henry (Crowdstrike) couldn't find the stolen emails.

Thread: Were Hunter Biden's emails processed in Chile?

Hunter Biden's emails were made available as a series of ~128K individual EML files (source Marco Polo).

The filenames have this form:
20100404-030027_36374.eml
where everything to the left of the underscore is a date/time.
Internal to the EML file is a Date: field. The Date value syntax is in the form that the sender sees the date/time. We can normalize that time to GMT and compare it to the date/time implied by the EML file name.
This should tell us the time zone in force when the EML files were prepared. Let's look at a couple of examples.

Can we estimate the time taken for a message to be sent to DAG1 vs DAG2 given the following data?

Alternatively, can we assert the level of significance that the path to DAG2 is slower than the path to DAG1? Image
Background: In the DNC emails we see some late dated emails (149 of them) sent locally via a server named DNCDAG2; for those emails we can subtract the sent time from the received time. Unfortunately, the times are accurate only to the nearest second.
To find a comparable set of emails sent via DNCDAG1, we look at a similar ~1 day time frame a week earlier. There are about 2x more emails in that sample, so we normalize those counts to total 149 (the DNCDAG2 value).

THREAD: solve the crime - how were the DNC emails taken?

In ou previous episode, we asserted that an email backup server had been hacked with Pacific/AZ time zone proximity.



Lading to the next question: how?
Before we address that question directly, let's rule out a few possibilities. First, let's recall that the DNC's on site experts had no clue. Image
Keep in mind that there would have been logs everywhere, VPN login logs, Windows login logs, Exchange server logs, and so on. We might believe that the logging levels were turned up higher when Crowdstrike visited the DNC almost a month before the hacks.

THREAD: Were the DNC emails taken from a backup server?

The Mueller Netyksho indictment asserts that the DNC emails, subsequently dumped by WikiLeaks (first on July 22, 2016) were acquired by Russian GRU agents who leveraged a hack of the DNC.
The indictment is vague on details raising many questions as to how exactly the emails were acquired, ex-filtrated and then transmitted to WikiLeaks.

As we’ll see below, even the on-scene experts who investigated the incident seemed to come up empty handed.
Before we cover the details, let’s have a look at the timeline. This is from the Forensicator’s analysis of the DNC emails. Image

The Unified Guccifer 2 Theory (1.0)

Recently, I had an "ah hah" moment w.r.t the timing and content of Guccifer 2's first blog post and the potential media/social network response.

It's an idea that I think may have merit, but pushing on that discovery string will be difficult.
spoiler: the DNC and friends got wind that a hacker (G2) was pitching the release of some HRC related documents to The Smoking Gun (TSG) and Gawker with stories to follow ...
Since G2's story might run counter to their hacking story, the DNC (and friends) hurriedly put together their hacking story and worked with media (WAPO) to get it out *ahead* of G2. In this way, they can set the narrative.

THREAD: Podesta wasn't phished.

The votes are in: 60/40 think that Podesta was phished. In this thread, I'll attempt to dissuade them of that opinion.
Background: Podesta used gmail; in mid-March 2016 about 50K of his emails (spanning years back) were ex-filtrated and later dumped by WL over a period of weeks starting October 7, 2016 (the day of the Access Hollywood release).
