Opinion

COURT OF APPEALS OF VIRGINIA

Present: Judges Humphreys, Russell and Senior Judge Bumgardner Argued at Norfolk, Virginia PUBLISHED

MATTHEW JOHN STICKLE OPINION BY v. Record No. 0660-16-1 JUDGE ROBERT J. HUMPHREYS DECEMBER 27, 2017 COMMONWEALTH OF VIRGINIA

FROM THE CIRCUIT COURT OF THE CITY OF WILLIAMSBURG AND COUNTY OF JAMES CITY Michael E. McGinty, Judge

Patricia Palmer Nagel for appellant.

John I. Jones, IV, Assistant Attorney General (Mark R. Herring, Attorney General, on brief), for appellee.

Matthew John Stickle (“Stickle”) appeals his December 16, 2015 conviction in the

Circuit Court of the City of Williamsburg and County of James City (the “circuit court”) on three

counts of possession of child pornography, first and second or subsequent offenses, and

twenty-two counts of possession of child pornography with intent to distribute.

I. Background

“In accordance with established principles of appellate review, we state the facts in the

light most favorable to the Commonwealth, the prevailing party in the [circuit] court. We also

accord the Commonwealth the benefit of all inferences fairly deducible from the evidence.”

Muhammad v. Commonwealth, 269 Va. 451, 479, 619 S.E.2d 16, 31 (2005).

So viewed, the evidence shows that on September 3, 2013, Lieutenant Scott Little

(“Little”), a district coordinator of the Southern Virginia Internet Crimes Against Children Task

Force, took part in an undercover investigation into what is known as peer-to-peer (“P2P”) distribution of child pornography over the internet. Little testified regarding his substantive role

in the investigation of Stickle and also testified without objection as an expert in the field of

digital forensics, in particular “as to the investigation of child exploitation offenses.”

Although the record reflects that much of Little’s testimony is somewhat technical, the

specifics are important to the legal analysis in this case and are essentially as follows:

What is generically referred to as “the internet” is a cooperatively managed global

network of smaller interconnected networks. Each internet site, whether such site is hosted on a

computer server or a single specific computer, is associated with a unique internet protocol

(“IP”) address. Likewise, each device accessing the internet, such as computers, tablets,

modems, routers, and smart phones, necessarily also is assigned a unique IP address to facilitate

two-way communication with other devices and locations on the internet.1 The most common

method of accessing internet sites is through a software application known as a “browser,” such

as Microsoft’s Internet Explorer or Apple’s Safari. Browsers can access that portion of the

internet known as the Worldwide Web or simply “the web,” which is the roughly fifteen percent

of the internet sites that have been assigned domain names and indexed by Google and other

search engines.2 Using a browser to access a site on the Worldwide Web requires that the link be

1 An IP address is a unique 128 bit number assigned by the Domain Name Server (“DNS”) of an internet service provider to each specific customer. IP addresses of individual devices within that customer’s premises are assigned and maintained by a DNS in a device called a router that creates a subnetwork within the premises based upon the IP address assigned by the internet service provider. Overall worldwide management of IP addresses and associated domain names is the responsibility of the Internet Corporation for Assigned Names and Numbers (ICANN). 2 The web is defined as a collection of links to the registered domain names of internet locations or “web pages” created using HTML (Hypertext Markup Language) thereby enabling them to be indexed by search engines and displayed in a browser. The remainder and vast majority of internet sites, known as the “deep web,” consists of unindexed, non-HTML locations, resources, and data that are encrypted, protected by a password, behind a paywall or otherwise beyond the reach of search engines and includes such things as email addresses, private networks

-2- routed through one or more DNS servers located throughout the world that maintain a current

database of IP addresses and their associated domain names and direct internet traffic to the

appropriate IP address.3

A less common, but nevertheless widely available and frequently used method of

reaching a specific IP address is through a direct link that is not relayed through a routing DNS.

Using specialized but readily obtainable software designed for the purpose, a direct, encrypted

“peer-to-peer” or “P2P” link can be established between a user’s computer and a specific folder

or file on any linked computer—provided that the owner of the destination computer is using

similar P2P software and has allowed specific access to such folder or file location.

In short, P2P networks use locally installed software called a “client” which allows users

to share computer files of their choice directly with other similarly equipped users (a “peer”) and

without any intermediary routing. Files which a user intends to share are kept in a specific folder

designated as sharable by the software client. While there is nothing inherently illegal about the

use of peer-to-peer file sharing, P2P software is often used to share files in violation of copyright

and other intellectual property laws and to facilitate communications regarding various types of

and on-line banking sites. A small, encrypted subset of the deep web known as the “dark web” consists of peer-to-peer networks such as Tor, Freenet or, as in this case, ARES, and requires specific software, hardware configurations or authorization to access. See generally, Andy Greenberg, Hacker Lexicon: What Is the Dark Web?, Wired Magazine, November 19, 2014. 3 By way of example, www.vacourts.gov is the domain name registered with ICANN for the internet site hosting the on-line presence of the judicial department of the Commonwealth of Virginia. Entering www.vacourts.gov into a web browser will cause it to contact a DNS, lookup the IP address assigned to the domain name www.vacourts.gov which will return the associated IP address 208.210.219.101 and then link to that IP address and display the web page located there.

-3- criminal activity.4 Because P2P locations in the dark web are invisible to indexing and search

engines such as Google, specialized software is required to access each separate P2P network.

Little was focusing his investigative attention on the ARES P2P network, which is often

used to exchange child pornography. Testifying as an expert, Little explained how peer-to-peer

networks are used in the context of the exchange of child pornography.

In a P2P network generally, users place any files they wish to share with others in a

specific “shared” folder. P2P clients like ARES globally search all shared folders in the P2P

network for any specified files. If found, the client then connects directly to all “peers,” i.e.

computers with shared folders that host the particular file being sought, and different pieces of

the file are then downloaded from multiple peers and reassembled into a new whole copy which

is then saved to the user’s shared folder.5

Specifically, with respect to the use of ARES, Little testified that file source IP addresses

are always collected by a P2P client, but in the stock version of ARES, they are not normally

displayed to the user. An ARES user enters the name of any file sought into the ARES client.
