You’ve likely heard of the dark web. This ominous sounding shadow internet rose in prominence alongside cryptocurrencies in the early 2010s, eventually becoming such an ingrained part of our cultural zeitgeist that it even received its own feature on an episode of Law & Order: SVU. But as prominent as the dark web may be, few average internet users can properly explain what it is and the cyber threats it provides a haven for. Let’s step back from the pop culture mythos and dive into what makes the dark web so dark.

Open Web, Deep Web, and Dark Web:
Know the Difference

The open web, or surface web, is the internet we use
every day. This includes all the web content that can be found through search
engines and is accessed by traditional web browsers. Though you might find it
surprising that the open web accounts for just
5% of the internet.
The rest is made up of the deep web. 

The deep web is the section of the internet that is
not indexed by search engines and cannot be found through traditional search
methods. This means that the only way to access deep web content is through a
direct URL. While rumors about the deep web make it seem as if it is
exclusively used for nefarious purposes, content on the deep web is often
banal. It is largely comprised of school and university intranet systems, email
and banking portals, internal sites for businesses and trade organizations, and
even things like your Netflix or Hulu queues. Nothing to be afraid of there.

While the dark web is technically a part of the deep web, it takes anonymity a step further by using overlay networks to restrict access, often attracting users engaged in illicit activity. These networks use special anonymized software to grant users access; the largest and most famous of which is Tor. Tor stands for “The Onion Router,” which references its “onion routing” technique of using encapsulated layers of encryption to ensure privacy. Tor websites are most easily recognized by their “.onion” domains, and by the fact that they cannot be accessed through traditional web browsers. You may have heard stories about the NSA trying to shut Tor down, but don’t expect the services to go away soon. It has funding from high places, with a recent FOI request revealing that one of Tor’s largest financial contributors has long been the U.S. State Department—likely to offer encrypted communication options for State Department agents working in the field.

Is the Dark Web Illegal?

The dark web isn’t inherently illegal—the illegality comes
from how it can be used. Darknet markets, such as the infamous and now
defunct original Silk Road, showcase how thin the line is between legal and
illegal dark market activities. As long as what you are purchasing is legal, using a darknet market is
as lawful as making a purchase from any other online retailer. But buying
illicit drugs or human
organs?
Yeah, that’s definitely illegal. 

Although not as remarkable as some of the more grotesque items available, one of the most commonly found items for sale on the dark web is data. With a reported 281 data breaches in just the first quarter of 2019, we have already seen 4.53 billion records exposed this year alone. That’s potentially more than 4 billion chances for hackers to profit off the victimization of strangers, and a majority of them will use the dark web to do so. We have seen several high-profile data breaches resurface on the dark web—Equifax, Canva, Under Armor, and Evite all recently had their user data available for sale on darknet markets.

The Dark Web and Malware-as-a-Service

Beyond selling your data, the dark web can be used to
harvest it as well. Webroot Security Analyst, Tyler Moffitt, explains this
growing threat:

“Anyone can create malware in today’s landscape where
the dark web is very accessible,” says Moffit. “There are ransomware services
on .onion links that will allow you to input just a few bits of information,
like a bitcoin address, desired ransom, late fees, etc., and unique binaries
are generated to distribute however they like. The only ‘catch’ is that the
portal creator usually takes a cut (around 30%) for any ransom payments
made.”

These malware-as-a-service attacks mean that an attacker doesn’t even need to know how to execute one; they just need to know how to navigate to the portal. Therein lies the largest dark web danger for many consumers—anonymized cyberattacks available at the click of a mouse.

Keeping Your Data Off the Dark Web

Like a hydra with its multiple heads, black markets will likely
never be wiped out. When you shut one down, two more will pop up. Darknet
markets are just their newest evolution. While you can’t expect to see this
threat disappear anytime soon, you can take steps to keep your data secure and
off the dark web.

Using an up-to-date antivirus
solution
will help stop malware from scraping your data on the dark
web. You can also lock
your credit
(called freezing) to help prevent new credit lines being open
without additional information. Another recommendation is avoiding public WiFi without a
VPN
, as it leaves you susceptible to a man-in-the-middle attack
(MITM). Even with these precautions, a breach may still occur. Keeping your
sensitive accounts secured with a trusted password manager can also help
prevent cyber attacks from spreading beyond their breach point.
