Trust this “Amazon” phishing email in Japan—and you’re Prime sashimi 🎣 🍣

Looking into our malspam data, we identified an active campaign impersonating Amazon and targeting Japanese citizens. The emails use subjects such as 「至急 Amazonプライム会員情報の確認」 (“Urgent: Confirm Amazon Prime member information”).

The URLs within the emails ultimately lead to an Amazon phishing page, but only after routing victims through a TDS. Interestingly, instead of keeping the TDS step invisible, the actors chose to show it off—repackaging it as a reassuring security check.

Upon clicking the link within the email, victims are first redirected to an RDGA TDS domain, where fingerprinting occurs. If the user does not match the targeting criteria (e.g., connecting from outside Japan), access is blocked. If they do match, potential victims are redirected to a second RDGA domain.
This second and last domain is not a TDS domain, but funny enough, these actors decided they would emulate it anyway!

At that step victims are already at the landing page but instead of immediately displaying a standard Amazon phishing page, the website displays a CAPTCHA and fake console interface simulating environment fingerprinting checks to “make sure your environment and connection is safe” before "proceeding to the landing page". Ironically, part of their message is true: fingerprinting did happen one domain earlier. It just wasn’t for the user’s benefit—it was to make sure the environment was safe… for the scammers. A few seconds later, without added user interaction needed, a fake Amazon login page is displayed.

💬 Telegram plays an important role in many underground businesses. Threat actors commonly stand up channels to market and support malicious activities such as malware-as-a-service (MaaS) subscriptions. While investigating ScreenConnect servers, a remote access support tool commonly abused by threat actors, we found an interesting business that we had never seen before. This actor used telegram as a storefront and support channel for an underground Remote Access Toolkit Online (RATO) platform. Technically RATO is a service that bundles cPanel and ScreenConnect technology to help its cyber criminal customers remotely access victim machines and manage scams, phishing, and malware (e.g. Latrodectus).

🐀 🔴 We discovered several servers that matched a ScreenConnect signature but these instances did not serve the typical ScreenConnect web content. Instead, their service is called "RATO PLATFORM" and the portal page shows the slogan "Can't catch the RAT__". We've found several telegram channels that promote services named "RATO", use the rat head logo (see attached image), or the domain rato[.]to. Based on their telegram chat content, it's clear their business model is focused on enabling cybercrime.

Consistent with RATO’s “BulletProof & Anti-Red Hosting” feature, we saw many RATO instances on ASNs with a high concentration of malicious activity (e.g., AS202412). Additionally, RATO infrastructure shows strong ties to Indonesia including Indonesian IP addresses in passive DNS and domains within the same cloudflare account used for serving online gambling to Indonesian-speaking users. Collectively, RATO and its customers operate a large number of domains. Here are some examples:
