WhatsApp, Japan, and a 500% Traffic Spike! 💹 🚨
To be honest, we thought threat actors were tripping when we saw a new WhatsApp phishing campaign targeting Japanese citizens. Don't they know LINE is the app in Japan? Well, we were surprised because this campaign is actually working…
The campaign doesn't only impersonate WhatsApp through its phishing page, but also through the lookalike domains it uses. Around 2k "WhatsApp" domain name variations are involved. The actor also leverages RDGAs – mostly for subdomains. Domains like web-rka-whatsapp[.]com[.]cn have up to 32 RDGA subdomains!
Upon visiting one of these lookalike domains, the user is fingerprinted and only forwarded to the phishing page if they match the intended profile — otherwise they get redirected to sites like bing[.]com or microsoft[.]com. As we show at the image below (with an AI-translated version), the malicious landing page simulates the WhatsApp login screen and encourages victims to scan a malicious QR code with their phone to log in.
When we found the cluster, we genuinely didn't think this campaign would land in Japan — but we were wrong. In the last 6 months, traffic to these domains has increased more than 500%, and it continues to rise.
What impact would these top quality lookalikes have if the campaigns were directed at countries where WhatsApp is actually the preferred messaging app?
Domain sample:
whatsappweb[.]net
whatapapp[.]com
whatsptapp[.]com

We planned one report on Keitaro abuse, but we ran out of pages before we ran out of cases.
So here’s Part 2 of 3, a medley of threats that go well beyond AI‑investment scams.Threat actors abuse Keitaro’s traffic distribution, cloaking, and rule engine to hide malicious landing pages behind geo and device-based filters. They stack bulletproof hosting and reverse proxies to add layers of indirection, making takedown and analysis harder. In this post, we share how we overcame this using multi‑protocol, multi‑vantage telemetry. We leveraged JA4+ web server fingerprints, DNS analytics, and Confiant’s visibility into advertising supply chain data to uncover Keitaro abuse and the delivery of malware downloaders, infostealers, weaponized RMMs, wallet drainer campaigns, scams, and email spam and advertising attack vectors.
If you hunt threats distributed via adtech, these indicators can be useful pivots. https://www.infoblox.com/blog/threat-intelligence/no-reach-no-risk-the-keitaro-abuse-in-modern-cybercrime-distribution/

🔴 A threat isn't much of a threat if it can't reach the right victims. 📦 That's why many modern threat actors rely on cloakers and traffic distribution systems (TDS) to target, route, and hide at scale. In a six‑month joint effort analyzing four months of data with Confiant, we identified 15,500 domains configured to Keitaro instances and actively used in cyber campaigns. Keitaro is a legitimate ad tracker, but it is frequently misused by cybercriminals as an all‑in‑one tracker + TDS + cloaker in scam and malware campaigns. We encounter Keitaro in our investigations nearly every day, and we set out to quantify that abuse in the broader landscape. We're publishing a three‑part series to share what we learned. Part 1 focuses on a subset of actors who leverage AI in their operations, most of whom are tied to investment scams. At the end of the report, you'll find a link to our github repository that contains thousands of related Keitaro iocs.

📱Smishing Slows, Quishing Quickens 🎣
Sick of smishing and those pesky parking/toll texts? Don’t get caught by crafty, counterfeit court QR codes — it’s a scan-and-scam! 💳 🚨
North American cell phone users are being hit with yet another wave of smishing campaigns that now include quishing elements. Likely orchestrated by Chinese-speaking threat actors, this latest campaign builds on previous vehicular violations, evolving tactics while impersonating US courts. 🧑⚖️
We’ve recently seen a flurry of SMS messages pushing parking violations — but with a twist: face justice in court… or scan and pay instead!
Delivered as an official-looking image, the actor has begun integrating QR codes into these lures to help mask suspicious phishing URLs, baiting victims into entering personal information, credentials, and ultimately making payments.
For some, this lure may sound better than facing justice for their perceived poor parking. Victims who don't comply are warned that failure to appear or pay could have serious repercussions - a scare tactic designed to push you toward a hasty decision and scanning the QR code! 🫣
We uncovered thousands of these nefarious domains, through their use of Registered Domain Generation Algorithms (RDGAs) and local government impersonation, hosted across a diverse range of hosting providers to evade takedown.
Recent examples:
⛔ ahfgx[.]icu
⛔ euoyq[.]icu
⛔ htpze[.]icu
⛔ mwlaj[.]icuFriendly reminder - courts don't usually communicate with you via text. That said, we suspect this actor will continue to evolve, expanding their global reach and diversifying lures while improving tradecraft used in smishing and quishing delivery. As for us, we'll take our chances on evading that bench warrant and running from the law. 🏃♂️➡️

After three years of relentless tracking, we’ve published a [paper](https://blogs.infoblox.com/threat-intelligence/vextrios-origin-story-from-spam-to-scam-to-adtech/) that, for the first time, exposes the true identities behind VexTrio. This research connects real names to the various companies that form the VexTrio ecosystem. It begins with the origin story—how a group of Italians launched a successful spam and dating business. Over time, VexTrio expanded its operations into malicious adtech and online scams. For over a decade, the group employed deceptive tactics to defraud countless innocent internet users. These illegitimate gains funded the extravagant lifestyles of VexTrio’s key figures—who, despite increasing scrutiny, have yet to be fully stopped.
We’re deeply grateful to all the contributors who helped us reach this research milestone, especially @rmceoin and Tord from [Qurium](https://www.qurium.org/).
