A sprawling academic cheating network turbocharged by Google Ads that has generated nearly $25 million in revenue has curious ties to a Kremlin-connected oligarch whose Russian university builds drones for Russia’s war against Ukraine.

The link between essay mills and Russian attack drones might seem improbable, but understanding it begins with a simple question: How does a human-intensive academic cheating service stay relevant in an era when students can simply ask AI to write their term papers? The answer – recasting the business as an AI company – is just the latest chapter in a story of many rebrands that link the operation to Russia’s largest private university.
Search in Google for any terms related to academic cheating services — e.g., “help with exam online” or “term paper online” — and you’re likely to encounter websites with the words “nerd” or “geek” in them, such as thenerdify[.]com and geekly-hub[.]com. With a simple request sent via text message, you can hire their tutors to help with any assignment.
These nerdy and geeky-branded websites frequently cite their “honor code,” which emphasizes they do not condone academic cheating, will not write your term papers for you, and will only offer support and advice for customers. But according to This Isn’t Fine, a Substack blog about contract cheating and essay mills, the Nerdify brand of websites will happily ignore that mantra.
“We tested the quick SMS for a price quote,” wrote This Isn’t Fine author Joseph Thibault. “The honor code references and platitudes apparently stop at the website. Within three minutes, we confirmed that a full three-page, plagiarism- and AI-free MLA formatted Argumentative essay could be ours for the low price of $141.”
A screenshot from Joseph Thibault’s Substack post shows him purchasing a 3-page paper with the Nerdify service.
Google prohibits ads that “enable dishonest behavior.” Yet, a sprawling global essay and homework cheating network run under the Nerdy brands has quietly bought its way to the top of Google searches – booking revenues of almost $25 million through a maze of companies in Cyprus, Malta and Hong Kong, while pitching “tutoring” that delivers finished work that students can turn in.
When one Nerdy-related Google Ads account got shut down, the group behind the company would form a new entity with a front-person (typically a young Ukrainian woman), start a new ads account along with a new website and domain name (usually with “nerdy” in the brand), and resume running Google ads for the same set of keywords.
UK companies belonging to the group that have been shut down by Google Ads since Jan 2025 include:
–Proglobal Solutions LTD (advertised nerdifyit[.]com);
–AW Tech Limited (advertised thenerdify[.]com);
–Geekly Solutions Ltd (advertised geekly-hub[.]com).
Currently active Google Ads accounts for the Nerdify brands include:
-OK Marketing LTD (advertising geekly-hub[.]net), formed in the name of Olha Karpenko, a young Ukrainian woman;
–Two Sigma Solutions LTD (advertising litero[.]ai), formed in the name of Olekszij (Alexey) Pokatilo.

Mr. Pokatilo has been in the essay-writing business since at least 2009, operating a paper-mill enterprise called Livingston Research alongside Alexander Korsukov, who is listed as an owner. According to a lengthy account from a former employee, Livingston Research mainly farmed its writing tasks out to low-cost workers from Kenya, Philippines, Pakistan, Russia and Ukraine.
Pokatilo moved from Ukraine to the United Kingdom in Sept. 2015 and co-founded a company called Awesome Technologies, which pitched itself as a way for people to outsource tasks by sending a text message to the service’s assistants.
The other co-founder of Awesome Technologies is 36-year-old Filip Perkon, a Swedish man living in London who touts himself as a serial entrepreneur and investor. Years before starting Awesome together, Perkon and Pokatilo co-founded a student group called Russian Business Week while the two were classmates at the London School of Economics. According to the Bulgarian investigative journalist Christo Grozev, Perkon’s birth certificate was issued by the Soviet Embassy in Sweden.

Around the time Perkon and Pokatilo launched Awesome Technologies, Perkon was building a social media propaganda tool called the Russian Diplomatic Online Club, which Perkon said would “turbo-charge” Russian messaging online. The club’s newsletter urged subscribers to install in their Twitter accounts a third-party app called Tweetsquad that would retweet Kremlin messaging on the social media platform.
Perkon was praised by the Russian Embassy in London for his efforts: During the contentious Brexit vote that ultimately led to the United Kingdom leaving the European Union, the Russian embassy in London used this spam tweeting tool to auto-retweet the Russian ambassador’s posts from supporters’ accounts.
Neither Mr. Perkon nor Mr. Pokatilo replied to requests for comment.
A review of corporations tied to Mr. Perkon as indexed by the business research service North Data finds he holds or held director positions in several U.K. subsidiaries of Synergy University, Russia’s largest private education provider. Synergy has more than 35,000 students, and sells T-shirts with patriotic slogans such as “Crimea is Ours,” and “The Russian Empire — Reloaded.”
The president of Synergy University is Vadim Lobov, a Kremlin insider whose headquarters on the outskirts of Moscow reportedly features a wall-sized portrait of Russian President Vladimir Putin in the pop-art style of Andy Warhol. For a number of years, Lobov and Perkon co-produced a cross-cultural event in the U.K. called Russian Film Week.

Mr. Lobov was one of 11 individuals reportedly hand-picked by the convicted Russian spy Marina Butina to attend the 2017 National Prayer Breakfast held in Washington D.C. just two weeks after President Trump’s first inauguration.
While Synergy University promotes itself as Russia’s largest private educational institution, hundreds of international students tell a different story. Online reviews from students paint a picture of unkept promises: Prospective students from Nigeria, Kenya, Ghana, and other nations paying thousands in advance fees for promised study visas to Russia, only to have their applications denied with no refunds offered.
“My experience with Synergy University has been nothing short of heartbreaking,” reads one such account. “When I first discovered the school, their representative was extremely responsive and eager to assist. He communicated frequently and made me believe I was in safe hands. However, after paying my hard-earned tuition fees, my visa was denied. It’s been over 9 months since that denial, and despite their promises, I have received no refund whatsoever. My messages are now ignored, and the same representative who once replied instantly no longer responds at all. Synergy University, how can an institution in Europe feel comfortable exploiting the hopes of Africans who trust you with their life savings? This is not just unethical — it’s predatory.”
This pattern repeats across reviews by multilingual students from Pakistan, Nepal, India, and various African nations — all describing the same scheme: Attractive online marketing, promises of easy visa approval, upfront payment requirements, and then silence after visa denials.
Reddit discussions in r/Moscow and r/AskARussian are filled with warnings. “It’s a scam, a diploma mill,” writes one user. “They literally sell exams. There was an investigation on Rossiya-1 television showing students paying to pass tests.”
The Nerdify website’s “About Us” page says the company was co-founded by Pokatilo and an American named Brian Mellor. The latter identity seems to have been fabricated, or at least there is no evidence that a person with this name ever worked at Nerdify.
Rather, it appears that the SMS assistance company co-founded by Messrs. Pokatilo and Perkon (Awesome Technologies) fizzled out shortly after its creation, and that Nerdify soon adopted the process of accepting assignment requests via text message and routing them to freelance writers.
A closer look at an early “About Us” page for Nerdify in The Wayback Machine suggests that Mr. Perkon was the real co-founder of the company: The photo at the top of the page shows four people wearing Nerdify T-shirts seated around a table on a rooftop deck in San Francisco, and the man facing the camera is Perkon.

Where are they now? Pokatilo is currently running a startup called Litero.Ai, which appears to be an AI-based essay writing service. In July 2025, Mr. Pokatilo received pre-seed funding of $800,000 for Litero from an investment program backed by the venture capital firms AltaIR Capital, Yellow Rocks, Smart Partnership Capital, and I2BF Global Ventures.
Meanwhile, Filip Perkon is busy setting up toy rubber duck stores in Miami and in at least three locations in the United Kingdom. These “Duck World” shops market themselves as “the world’s largest duck store.”
This past week, Mr. Lobov was in India with Putin’s entourage on a charm tour with India’s Prime Minister Narendra Modi. Although Synergy is billed as an educational institution, a review of the company’s sprawling corporate footprint (via DNS) shows it also is assisting the Russian government in its war against Ukraine.

The website bpla.synergy[.]bot, for instance, says the company is involved in developing combat drones to aid Russian forces and to evade international sanctions on the supply and re-export of high-tech products.

Update, Dec. 8, 10:06 a.m. ET: Mr. Pokatilo responded to requests for comment after the publication of this story. Pokatilo said he has no relation to Synergy nor to Mr. Lobov, and that his work with Mr. Perkon ended with the dissolution of Awesome Technologies.
“I have had no involvement in any of his projects and business activities mentioned in the article and he has no involvement in Litero.ai,” Pokatilo said of Perkon.
Mr. Pokatilo said his new company Litero “does not provide contract cheating services and is built specifically to improve transparency and academic integrity in the age of universal use of AI by students.”
“I am Ukrainian,” he said in an email. “My close friends, colleagues, and some family members continue to live in Ukraine under the ongoing invasion. Any suggestion that I or my company may be connected in any way to Russia’s war efforts is deeply offensive on a personal level and harmful to the reputation of Litero.ai, a company where many team members are Ukrainian.”
Update, Dec. 11, 12:07 p.m. ET: Mr. Perkon responded to requests for comment after the publication of this story. Perkon said the photo of him in a Nerdify T-shirt (see screenshot above) was taken after a startup event in San Francisco, where he volunteered to act as a photo model to help friends with their project.
“I have no business or other relations to Nerdify or any other ventures in that space,” Mr. Perkon said in an email response. “As for Vadim Lobov, I worked for Venture Capital arm at Synergy until 2013 as well as his business school project in the UK, that didn’t get off the ground, so the company related to this was made dormant. Then Synergy kindly provided sponsorship for my Russian Film Week event that I created and ran until 2022 in the U.K., an event that became the biggest independent Russian film festival outside of Russia. Since the start of the Ukraine war in 2022 I closed the festival down.”
“I have had no business with Vadim Lobov since 2021 (the last film festival) and I don’t keep track of his endeavours,” Perkon continued. “As for Alexey Pokatilo, we are university friends. Our business relationship has ended after the concierge service Awesome Technologies didn’t work out, many years ago.”
Summer is synonymous with vacations, a time when families pack their bags, grab their sunscreen, and embark on exciting adventures. In the digital age, smartphones have become an indispensable part of our lives, serving as cameras, maps, entertainment hubs, and communication tools. While these devices enhance our travel experiences, they also become prime targets for theft or damage while we’re away from home. From keeping us connected with family and friends, assisting in navigation, capturing moments, to even helping us with language translation – it is a device of many conveniences. However, when you bring your smartphone while vacationing, like any other valuable item, it becomes a target for theft and damage. Not to mention the potential for high roaming charges.
Don’t let the fear of losing or damaging your valuable devices dampen your vacation spirit! By taking some simple precautions and implementing effective strategies, you can ensure that your family’s smartphones remain safe and secure throughout your travels. In this blog post, we’ll share essential tips and tricks for safeguarding your devices, so you can focus on creating unforgettable memories without any tech-related worries. This article will provide you with tips on how to protect your family’s smartphones while on vacation. We will cover strategies like enabling security settings, backing up data, checking for travel insurance policies, and utilizing helpful apps. Ensuring the safety of your devices will make your vacation more enjoyable and worry-free.
Traveling without smartphones seems almost impossible. However, having them on vacation puts them at risk. In tourist hotspots, where distractions are many, it is easy to lose or have your device stolen. Moreover, using public Wi-Fi networks can expose your smartphone to cyber attacks.

Therefore, it is vital to be proactive in securing both your smartphones and the data they contain. Not only will it save you from the high costs of replacing a lost or damaged phone, but it also prevents potential misuse of personal and financial information. Implementing even just a few of these safety measures can help ensure your family’s smartphones are well-protected during your vacation. So let’s dive into the practical steps you can take.
The first layer of protection for your phone should be a physical one. It starts with investing in a good quality, durable phone case. A waterproof case is always a good idea, especially if you’re planning on vacationing near the beach or a pool. A screen protector can also keep your screen from shattering or getting scratched. Remember, you’re more likely to drop your phone while on vacation as you juggle through maps, travel apps, and numerous photo opportunities.
Another aspect of physical protection is to be mindful of where you store your phone. Avoid leaving it in plain sight or unattended, which could invite potential thieves. Instead, carry it in a secure, zipped pocket or bag. If you’re staying at a hotel, consider using the safe to store your phone when not in use. Most importantly, be aware of your surroundings and keep your phone safely tucked away in crowded places.

Safeguarding your phone is not just about protecting the physical device—your personal and sensitive data deserves protection too. Before you leave for your vacation, make sure that your phone is password-protected. Optimally, use a complex password, fingerprint, or face recognition feature instead of a simple four-digit PIN. This singular step can deter any prying eyes from accessing your information if your phone is lost or stolen.
Ensure your phone’s software is up to date. Regular updates not only enhance the device’s performance but also incorporate vital security patches, fortifying its defenses against potential threats like malware. By staying vigilant and keeping your phone’s software current, you contribute to a more secure environment, minimizing the risk of unauthorized eyes accessing your valuable information in the event of a loss or theft.
Backing up your smartphone’s data before leaving for vacation can save you from a lot of stress. In case of loss, theft, or damage, having a backup ensures that you won’t lose your cherished photos, contacts, and other essential data. Most smartphones allow you to back up your data to the cloud. Make sure to do this over a safe, secure network and not on public Wi-Fi.
For Android users, Google provides an automatic backup service for things like app data, call history, and settings. You can check if this feature is enabled on your phone by going to the Google Drive App and checking in the Backups section. For iPhone users, iCloud Backup can help save most of your data and settings. To enable it, go to Settings, tap on your name, then tap iCloud and scroll down to tap iCloud Backup.
Without proper management, staying connected while abroad can result in expensive roaming charges. Before you leave, check with your mobile provider to understand the costs associated with using your phone abroad. Some providers offer international plans that you can temporarily switch to for your vacation. If your provider’s charges are too high, consider purchasing a local SIM card once you arrive at your destination or use an international data package.
Another way to avoid roaming charges is by using Wi-Fi. Most hotels, cafes, and many public spaces have free Wi-Fi available. However, again, public Wi-Fi is not always safe. So, avoid accessing sensitive information such as bank accounts, and before traveling, download maps and essential content before traveling to reduce the need for constant data usage. This is especially helpful for navigation apps. To protect your data in such situations, it’s advisable to use a Virtual Private Network (VPN).
Several apps can help protect your phone and its data during your vacation. Most smartphone operating systems offer a “Find My Phone” feature that can locate, lock, or erase your device if it is lost or stolen. Make sure this feature is enabled before you leave.
Again, antivirus apps can provide an extra layer of protection against virus and malware threats. Password manager apps can help you create and store complex, unique passwords for your accounts to enhance security.
VPN apps can protect your data from being intercepted when using public Wi-Fi networks. There are also apps that monitor your data usage and can alert you if you’re near your limit to avoid unexpected charges. Research and install these apps prior to your vacation for added security and peace of mind.
Your family’s smartphones are essential travel companions that deserve as much protection as any other valuable item during your vacation. By physically safeguarding the device, securing your data, backing up regularly, understanding roaming charges, and utilizing productive apps, you can enjoy a worry-free vacation. Remember, in the event of a mishap, having travel insurance can provide an extra layer of financial protection. So, before setting off, review your policy and check if it covers lost or stolen devices. In the end, preparation is key, so take the time to implement these safety measures and enjoy your vacation with peace of mind.
Above and beyond security settings and software, there’s you. Get in the habit of talking with your child for a sense of what they’re doing online. As a mom, I like to ask them about their favorite games, share some funny TikTok clips or cute photos with them, and generally make it a point to be a part of their digital lives. It’s great, because it gives you peace of mind knowing what types of things they are doing or interactions they are having online.
For those of you hitting the road in the coming weeks, enjoy your travels, wherever they take you!

Virtual private networking (VPN) companies market their services as a way to prevent anyone from snooping on your Internet usage. But new research suggests this is a dangerous assumption when connecting to a VPN via an untrusted network, because attackers on the same network could force a target’s traffic off of the protection provided by their VPN without triggering any alerts to the user.

When a device initially tries to connect to a network, it broadcasts a message to the entire local network stating that it is requesting an Internet address. Normally, the only system on the network that notices this request and replies is the router responsible for managing the network to which the user is trying to connect.
The machine on a network responsible for fielding these requests is called a Dynamic Host Configuration Protocol (DHCP) server, which will issue time-based leases for IP addresses. The DHCP server also takes care of setting a specific local address — known as an Internet gateway — that all connecting systems will use as a primary route to the Web.
VPNs work by creating a virtual network interface that serves as an encrypted tunnel for communications. But researchers at Leviathan Security say they’ve discovered it’s possible to abuse an obscure feature built into the DHCP standard so that other users on the local network are forced to connect to a rogue DHCP server.
“Our technique is to run a DHCP server on the same network as a targeted VPN user and to also set our DHCP configuration to use itself as a gateway,” Leviathan researchers Lizzie Moratti and Dani Cronce wrote. “When the traffic hits our gateway, we use traffic forwarding rules on the DHCP server to pass traffic through to a legitimate gateway while we snoop on it.”
The feature being abused here is known as DHCP option 121, and it allows a DHCP server to set a route on the VPN user’s system that is more specific than those used by most VPNs. Abusing this option, Leviathan found, effectively gives an attacker on the local network the ability to set up routing rules that have a higher priority than the routes for the virtual network interface that the target’s VPN creates.
“Pushing a route also means that the network traffic will be sent over the same interface as the DHCP server instead of the virtual network interface,” the Leviathan researchers said. “This is intended functionality that isn’t clearly stated in the RFC [standard]. Therefore, for the routes we push, it is never encrypted by the VPN’s virtual interface but instead transmitted by the network interface that is talking to the DHCP server. As an attacker, we can select which IP addresses go over the tunnel and which addresses go over the network interface talking to our DHCP server.”
Leviathan found they could force VPNs on the local network that already had a connection to arbitrarily request a new one. In this well-documented tactic, known as a DHCP starvation attack, an attacker floods the DHCP server with requests that consume all available IP addresses that can be allocated. Once the network’s legitimate DHCP server is completely tied up, the attacker can then have their rogue DHCP server respond to all pending requests.
“This technique can also be used against an already established VPN connection once the VPN user’s host needs to renew a lease from our DHCP server,” the researchers wrote. “We can artificially create that scenario by setting a short lease time in the DHCP lease, so the user updates their routing table more frequently. In addition, the VPN control channel is still intact because it already uses the physical interface for its communication. In our testing, the VPN always continued to report as connected, and the kill switch was never engaged to drop our VPN connection.”
The researchers say their methods could be used by an attacker who compromises a DHCP server or wireless access point, or by a rogue network administrator who owns the infrastructure themselves and maliciously configures it. Alternatively, an attacker could set up an “evil twin” wireless hotspot that mimics the signal broadcast by a legitimate provider.
Bill Woodcock is executive director at Packet Clearing House, a nonprofit based in San Francisco. Woodcock said Option 121 has been included in the DHCP standard since 2002, which means the attack described by Leviathan has technically been possible for the last 22 years.
“They’re realizing now that this can be used to circumvent a VPN in a way that’s really problematic, and they’re right,” Woodcock said.
Woodcock said anyone who might be a target of spear phishing attacks should be very concerned about using VPNs on an untrusted network.
“Anyone who is in a position of authority or maybe even someone who is just a high net worth individual, those are all very reasonable targets of this attack,” he said. “If I were trying to do an attack against someone at a relatively high security company and I knew where they typically get their coffee or sandwich at twice a week, this is a very effective tool in that toolbox. I’d be a little surprised if it wasn’t already being exploited in that way, because again this isn’t rocket science. It’s just thinking a little outside the box.”
Successfully executing this attack on a network likely would not allow an attacker to see all of a target’s traffic or browsing activity. That’s because for the vast majority of the websites visited by the target, the content is encrypted (the site’s address begins with https://). However, an attacker would still be able to see the metadata — such as the source and destination addresses — of any traffic flowing by.
KrebsOnSecurity shared Leviathan’s research with John Kristoff, founder of dataplane.org and a PhD candidate in computer science at the University of Illinois Chicago. Kristoff said practically all user-edge network gear, including WiFi deployments, support some form of rogue DHCP server detection and mitigation, but that it’s unclear how widely deployed those protections are in real-world environments.
“However, and I think this is a key point to emphasize, an untrusted network is an untrusted network, which is why you’re usually employing the VPN in the first place,” Kristoff said. “If [the] local network is inherently hostile and has no qualms about operating a rogue DHCP server, then this is a sneaky technique that could be used to de-cloak some traffic – and if done carefully, I’m sure a user might never notice.”
According to Leviathan, there are several ways to minimize the threat from rogue DHCP servers on an unsecured network. One is using a device powered by the Android operating system, which apparently ignores DHCP option 121.
Relying on a temporary wireless hotspot controlled by a cellular device you own also effectively blocks this attack.
“They create a password-locked LAN with automatic network address translation,” the researchers wrote of cellular hot-spots. “Because this network is completely controlled by the cellular device and requires a password, an attacker should not have local network access.”
Leviathan’s Moratti said another mitigation is to run your VPN from inside of a virtual machine (VM) — like Parallels, VMware or VirtualBox. VPNs run inside of a VM are not vulnerable to this attack, Moratti said, provided they are not run in “bridged mode,” which causes the VM to replicate another node on the network.
In addition, a technology called “deep packet inspection” can be used to deny all in- and outbound traffic from the physical interface except for the DHCP and the VPN server. However, Leviathan says this approach opens up a potential “side channel” attack that could be used to determine the destination of traffic.
“This could be theoretically done by performing traffic analysis on the volume a target user sends when the attacker’s routes are installed compared to the baseline,” they wrote. “In addition, this selective denial-of-service is unique as it could be used to censor specific resources that an attacker doesn’t want a target user to connect to even while they are using the VPN.”
Moratti said Leviathan’s research shows that many VPN providers are currently making promises to their customers that their technology can’t keep.
“VPNs weren’t designed to keep you more secure on your local network, but to keep your traffic more secure on the Internet,” Moratti said. “When you start making assurances that your product protects people from seeing your traffic, there’s an assurance or promise that can’t be met.”
A copy of Leviathan’s research, along with code intended to allow others to duplicate their findings in a lab environment, is available here.
