News4JAX reporter Briana Brownlee<\/a> and photojournalist Jesse Hanson took the case to the FBI\u2019s Jacksonville Field Office with a bigger question: How is the dark web changing the way illegal drugs are bought and sold?<\/p>\nAssistant Special Agent in Charge David Kadela could not discuss the specifics of the case involving the Chernyshov brothers, but met with News4JAX to explain how dark web marketplaces operate more broadly, why their ease of use concerns investigators and what buyers may be risking when they place an order.<\/p>\n
But Kadela said there is something about these marketplaces that may feel surprisingly familiar: the shopping experience.<\/p>\n
\u201cIf anyone has shopped online on the internet, then they would be very familiar with the dark web,\u201d Kadela said. \u201cSo when you go on the dark web to shop, it\u2019s like using any kind of online marketplace that you would experience in your everyday life, so the ease of use, of course, is a concern for the FBI.\u201d<\/p>\n
From \u2018BarbaraWhite\u2019 to a much bigger question<\/p>\n
Federal court records show the investigation involving the Chernyshov brothers began after a fatal overdose in Arlington, Virginia, in 2023.<\/p>\n
The brothers were arrested Aug. 28 and charged with conspiracy to distribute nitazenes.<\/p>\n

Prosecutors say Jacksonville brothers Vladislav and Stanislav Chernyshov were selling counterfeit oxycodone pills on the dark web under the name \u201cBarbara White.\u201d (WJXT)<\/p>\n
The Drug Enforcement Administration says it has reported 22 unique nitazene compounds since 2020, 21 of which are Schedule I controlled substances.<\/p>\n
The DEA has warned that emerging synthetic drugs, including nitazenes, can be mixed into counterfeit pills without the person taking them knowing what is actually inside.<\/p>\n
A marketplace that can feel familiar<\/p>\n
Kadela described the dark web as a system people can use to mask their identities and remain anonymous on networks such as Tor.<\/p>\n
Simply accessing the dark web is not illegal. Kadela said legitimate sites operate there, too.<\/p>\n
But he said its anonymous nature can also allow people engaged in criminal activity to mask their identities.<\/p>\n
He added that the FBI is particularly concerned about how dark web marketplaces can provide easier access to the illegal drug trade for people who may not have previously had connections to it.<\/p>\n

\u201cThe dark web allows easier access for newcomers to, you know, the drug trade, if you will,\u201d Kadela said. \u201cSo people who may not have connections or groups that they\u2019re a part of that traffic in illegal narcotics. So it is an easier gateway for newcomers to obtain these illegal products.\u201d<\/p>\n
Federal investigations into other dark web marketplaces show how closely some have mimicked legitimate online shopping sites.<\/p>\n
The Justice Department said Incognito Market, an online narcotics marketplace that operated from 2020 until 2024, was designed with features found on legitimate e-commerce websites, including branding, advertising and customer service.<\/p>\n
Users could search thousands of drug listings while operating under usernames. The Justice Department said the marketplace sold more than $100 million in narcotics before it shut down.<\/p>\n
In one investigation, an undercover agent purchased tablets advertised as oxycodone through Incognito Market. Laboratory testing showed the tablets contained fentanyl.<\/p>\n
From a computer screen to a mailbox<\/p>\n
The internet can also eliminate something traditionally associated with an illegal drug transaction: a face-to-face meeting.<\/p>\n
\u201cNow, the dark web marketplace that kind of can remove some of those dangers, and you can simply go online, order up what you want, and have it delivered via the mail,\u201d Kadela said.<\/p>\n
Kadela told News4JAX that illegal products purchased through these marketplaces can be mailed to an address or post office box.<\/p>\n
He also said purchases can be for personal use or distribution.<\/p>\n
And the person on the other side of the transaction does not necessarily have to be nearby.<\/p>\n
\u201cThey\u2019re here locally. They\u2019re in the state of Florida. They\u2019re in the United States. They\u2019re all over the world,\u201d Kadela said. \u201cSo really, given the nature of the internet, these marketplaces can be operated from anywhere.\u201d<\/p>\n
Are dark web users really anonymous?<\/p>\n
Anonymity is one of the reasons people may turn to the dark web, but Kadela said it does not necessarily put someone beyond the reach of investigators.<\/p>\n
\u201cThrough our investigative activity, we are usually able to identify the folks who are involved,\u201d Kadela said.<\/p>\n
Kadela declined to reveal how investigators connect an anonymous online identity to an actual person, including whether information such as IP addresses, names or physical addresses can play a role.<\/p>\n
Kadela said FBI field offices have cyber squads and cyber capabilities that investigate these marketplaces and attempt to identify the people operating them and buying illegal items.<\/p>\n
Hundreds arrested in global crackdown<\/p>\n
The Jacksonville case is one piece of a much larger federal effort targeting illegal dark web marketplaces.<\/p>\n
In Operation RapTor, an international law enforcement operation announced in 2025, authorities arrested 270 dark web vendors, buyers and administrators in the United States and several other countries.<\/p>\n
Authorities also seized more than $200 million in currency and digital assets, more than two metric tons of drugs, 144 kilograms of fentanyl or fentanyl-laced narcotics and more than 180 firearms.<\/p>\n
The Justice Department said evidence and leads obtained through previous marketplace takedowns have helped investigators pursue additional cases.<\/p>\n
Kadela told News4JAX the dark web remains an elevated problem and a priority for the FBI. He said investigations are active and law enforcement agencies continue working together on marketplace takedowns around the world.<\/p>\n
\u2018You just don\u2019t know what you\u2019re getting\u2019<\/p>\n
For all of the technology involved, Kadela said one of the biggest risks comes down to something much simpler: A buyer may have little way of knowing what is actually inside a pill.<\/p>\n
\u201cYou just don\u2019t know what you\u2019re getting because you know really oftentimes it\u2019s just someone in their basement who is pressing these pills,\u201d Kadela said. \u201cYou don\u2019t know what\u2019s in this pill, so that\u2019s why, if you consume one of these pills, it could kill you. So that\u2019s why it\u2019s such a concern in the FBI, and there\u2019s just no quality control to what you may be receiving.\u201d<\/p>\n
The allegations in the Jacksonville case underscore that concern.<\/p>\n
Prosecutors say pills associated with \u201cBarbaraWhite\u201d were sold as counterfeit oxycodone and advertised as \u201cfent free.\u201d Laboratory testing found nitazenes.<\/p>\n
The DEA advises people not to take pills that were not prescribed to them, to stick to medications dispensed by a licensed pharmacy and that illicit drugs may contain fentanyl or other substances without the person\u2019s knowledge.<\/p>\n
