Late final 12 months, safety researchers made a startling discovery: Kremlin-backed disinformation campaigns have been bypassing moderation on social media platforms by leveraging the identical malicious promoting expertise that powers a sprawling ecosystem of on-line hucksters and web site hackers. A brand new report on the fallout from that investigation finds this darkish advert tech trade is much extra resilient and incestuous than beforehand recognized.

In November 2024, researchers on the safety agency Qurium revealed an investigation into “Doppelganger,” a disinformation community that promotes pro-Russian narratives and infiltrates Europe’s media panorama by pushing faux information by way of a community of cloned web sites.
Doppelganger campaigns use specialised hyperlinks that bounce the customer’s browser by way of an extended sequence of domains earlier than the faux information content material is served. Qurium discovered Doppelganger depends on a classy “area cloaking” service, a expertise that enables web sites to current completely different content material to serps in comparison with what common guests see. The usage of cloaking providers helps the disinformation websites stay on-line longer than they in any other case would, whereas guaranteeing that solely the focused viewers will get to view the meant content material.
Qurium found that Doppelganger’s cloaking service additionally promoted on-line relationship websites, and shared a lot of the identical infrastructure with VexTrio, which is regarded as the oldest malicious visitors distribution system (TDS) in existence. Whereas TDSs are generally utilized by official promoting networks to handle visitors from disparate sources and to trace who or what’s behind every click on, VexTrio’s TDS largely manages internet visitors from victims of phishing, malware, and social engineering scams.
BREAKING BAD
Digging deeper, Qurium seen Doppelganger’s cloaking service used an Web supplier in Switzerland as the primary entry level in a sequence of area redirections. Additionally they seen the identical infrastructure hosted a pair of co-branded internet affiliate marketing providers that have been driving visitors to sketchy grownup relationship websites: LosPollos(.)com and TacoLoco(.)co.
The LosPollos advert community incorporates many components and references from the hit sequence “Breaking Dangerous,” mirroring the fictional “Los Pollos Hermanos” restaurant chain that served as a cash laundering operation for a violent methamphetamine cartel.
The LosPollos promoting community invokes characters and themes from the hit present Breaking Dangerous. The brand for LosPollos (higher left) is the picture of Gustavo Fring, the fictional rooster restaurant chain proprietor within the present.
Associates who enroll with LosPollos are given JavaScript-heavy “smartlinks” that drive visitors into the VexTrio TDS, which in flip distributes the visitors amongst a wide range of promoting companions, together with relationship providers, sweepstakes provides, bait-and-switch cell apps, monetary scams and malware obtain websites.
LosPollos associates sometimes sew these good hyperlinks into WordPress web sites which have been hacked by way of recognized vulnerabilities, and people associates will earn a small fee every time an Web consumer referred by any of their hacked websites falls for considered one of these lures.

In response to Qurium, TacoLoco is a visitors monetization community that makes use of misleading ways to trick Web customers into enabling “push notifications,” a cross-platform browser normal that enables web sites to indicate pop-up messages which seem exterior of the browser. For instance, on Microsoft Home windows techniques these notifications sometimes present up within the backside proper nook of the display — simply above the system clock.
Within the case of VexTrio and TacoLoco, the notification approval requests themselves are misleading — disguised as “CAPTCHA” challenges designed to tell apart automated bot visitors from actual guests. For years, VexTrio and its companions have efficiently tricked numerous customers into enabling these web site notifications, that are then used to repeatedly pepper the sufferer’s machine with a wide range of phony virus alerts and deceptive pop-up messages.

In response to a December 2024 annual report from GoDaddy, almost 40 p.c of compromised web sites in 2024 redirected guests to VexTrio by way of LosPollos smartlinks.
ADSPRO AND TECHNOLOGY
On November 14, 2024, Qurium revealed analysis to assist its findings that LosPollos and TacoLoco have been providers operated by Adspro Group, an organization registered within the Czech Republic and Russia, and that Adspro runs its infrastructure on the Swiss internet hosting suppliers C41 and Teknology SA.
Qurium famous the LosPollos and TacoLoco websites state that their content material is copyrighted by ByteCore AG and SkyForge Digital AG, each Swiss corporations which can be run by the proprietor of Teknology SA, Guilio Vitorrio Leonardo Cerutti. Additional investigation revealed LosPollos and TacoLoco have been apps developed by an organization referred to as Holacode, which lists Cerutti as its CEO.
The apps marketed by Holacode embrace quite a few VPN providers, in addition to one referred to as Spamshield that claims to cease undesirable push notifications. However in January, Infoblox mentioned they examined the app on their very own cell gadgets, and located it hides the consumer’s notifications, after which after 24 hours stops hiding them and calls for fee. Spamshield subsequently modified its developer identify from Holacode to ApLabz, though Infoblox famous that the Phrases of Service for a number of of the rebranded ApLabz apps nonetheless referenced Holacode of their phrases of service.
Extremely, Cerutti threatened to sue me for defamation earlier than I’d even uttered his identify or despatched him a request for remark (Cerutti despatched the unsolicited authorized menace again in January after his firm and my identify have been merely tagged in an Infoblox publish on LinkedIn about VexTrio).
Requested to touch upon the findings by Qurium and Infoblox, Cerutti vehemently denied being related to VexTrio. Cerutti asserted that his corporations all strictly adhere to the laws of the nations during which they function, and that they’ve been utterly clear about all of their operations.
“We’re a bunch working within the promoting and advertising house, with an affiliate community program,” Cerutti responded. “I’m not (going) to say we’re good, however I strongly declare we now have no reference to VexTrio in any respect.”
“Sadly, as a giant participant on this house we additionally get to cope with loads of writer fraud, sketchy visitors, faux clicks, bots, hacked, listed and resold writer accounts, and so on, and so on.,” Cerutti continued. “We bleed numerous cash to such malpractices and conduct common inside screenings and audits in a relentless battle to take away dangerous visitors sources. It is usually a extremely aggressive house, the place some upstarts will typically play soiled towards extra established mainstream gamers like us.”
Working with Qurium, researchers on the safety agency Infoblox launched particulars about VexTrio’s infrastructure to their trade companions. Simply 4 days after Qurium revealed its findings, LosPollos introduced it was suspending its push monetization service. Lower than a month later, Adspro had rebranded to Aimed International.

A REVEALING PIVOT
In March 2025, researchers at GoDaddy chronicled how DollyWay — a malware pressure that has constantly redirected victims to VexTrio all through its eight years of exercise — immediately stopped doing that on November 20, 2024. Nearly in a single day, DollyWay and a number of other different malware households that had beforehand used VexTrio started pushing their visitors by way of one other TDS referred to as Assist TDS.
Digging additional into historic DNS information and the distinctive code scripts utilized by the Assist TDS, Infoblox decided it has lengthy loved an unique relationship with VexTrio (at the least till LosPollos ended its push monetization service in November).
In a report launched immediatelyInfoblox mentioned an exhaustive evaluation of the JavaScript code, web site lures, smartlinks and DNS patterns utilized by VexTrio and Assist TDS linked them with at the least 4 different TDS operators (not counting TacoLoco). These 4 entities — Companions Home, BroPush, RichAds and RexPush — are all Russia-based push monetization packages that pay associates to drive signups for a wide range of schemes, however largely on-line relationship providers.
“As Los Pollos push monetization ended, we’ve seen a rise in faux CAPTCHAs that drive consumer acceptance of push notifications, notably from Companions Home,” the Infoblox report reads. “The connection of those industrial entities stays a thriller; whereas they’re actually long-time companions redirecting visitors to 1 one other, and so they all have a Russian nexus, there isn’t a overt frequent possession.”
Renee Burton, vp of menace intelligence at Infoblox, mentioned the safety trade typically treats the misleading strategies utilized by VexTrio and different malicious TDSs as a sort of legally gray space that’s largely related to much less harmful safety threats, equivalent to adware and scareware.
However Burton argues that this view is myopic, and helps perpetuate a darkish adtech trade that additionally pushes loads of straight-up malware, noting that a whole bunch of 1000’s of compromised web sites world wide yearly redirect victims to the tangled internet of VexTrio and VexTrio-affiliate TDSs.
“These TDSs are a nefarious menace, as a result of they’re those you may connect with the supply of issues like data stealers and scams that value shoppers billions of {dollars} a 12 months,” Burton mentioned. “From a bigger strategic perspective, my takeaway is that Russian organized crime has management of malicious adtech, and these are simply among the many teams concerned.”
WHAT CAN YOU DO?
As KrebsOnSecurity warned means again in 2020, it’s a good suggestion to be very sparing in approving notifications when shopping the Internet. In lots of circumstances these notifications are benign, however as we’ve seen there are quite a few dodgy corporations which can be paying web site homeowners to put in their notification scripts, after which reselling that communications pathway to scammers and on-line hucksters.
