At Microsoft, we proceed to search for inventive methods to guard individuals on-line and that features having no tolerance for individuals who create fraudulent copies of our merchandise to hurt others. Fraudulent on-line accounts act because the gateway to a number of cybercrime, together with mass phishing, identification theft and fraud, and distributed denial of service (DDoS) assaults. That’s the reason right this moment, we, with worthwhile menace intelligence insights from Arkose Labs, a number one cybersecurity protection and bot administration vendor, are going after the primary vendor and creator of fraudulent Microsoft accounts, a gaggle we name Storm-1152. We’re sending a robust message to those that search to create, promote or distribute fraudulent Microsoft merchandise for cybercrime: We’re watching, taking discover and can act to guard our clients.
Storm-1152 runs illicit web sites and social media pages, promoting fraudulent Microsoft accounts and instruments to bypass identification verification software program throughout well-known know-how platforms. These companies scale back the effort and time wanted for criminals to conduct a number of prison and abusive behaviors on-line. Up to now, Storm-1152 created on the market roughly 750 million fraudulent Microsoft accounts, incomes the group thousands and thousands of {dollars} in illicit income, and costing Microsoft and different firms much more to fight their prison exercise.
With right this moment’s motion, our objective is to discourage prison habits. By looking for to gradual the pace at which cybercriminals launch their assaults, we goal to boost their value of doing enterprise whereas persevering with our investigation and defending our clients and different on-line customers.
How cybercriminals use Storm-1152’s companies
Storm-1152 performs a major position within the extremely specialised cybercrime-as-a-service ecosystem. Cybercriminals want fraudulent accounts to help their largely automated prison actions. With firms capable of shortly determine and shut down fraudulent accounts, criminals require a larger amount of accounts to avoid mitigation efforts. As a substitute of spending time making an attempt to create 1000’s of fraudulent accounts, cybercriminals can merely buy them from Storm-1152 and different teams. This enables criminals to focus their efforts on their final objectives of phishing, spamming, ransomware, and different sorts of fraud and abuse. Storm-1152 and teams like them allow scores of cybercriminals to hold out their malicious actions extra effectively and successfully.
Microsoft Risk Intelligence has recognized a number of teams engaged in ransomware, information theft and extortion which have used Storm-1152 accounts. For instance, Octo Tempest, also called Scattered Spider, obtained fraudulent Microsoft accounts from Storm-1152. Octo Tempest is a financially motivated cybercrime group that leverages broad social engineering campaigns to compromise organizations throughout the globe with the objective of economic extortion. Microsoft continues to trace a number of different ransomware or extortion menace actors which have bought fraudulent accounts from Storm-1152 to boost their assaults, together with Storm-0252 and Storm-0455.
Our disruption technique
On Thursday, December 7, Microsoft obtained a court docket order from the Southern District of New York to grab U.S.-based infrastructure and take offline web sites utilized by Storm-1152 to hurt Microsoft clients. Whereas our case focuses on fraudulent Microsoft accounts, the web sites impacted additionally offered companies to bypass safety measures on different well-known know-how platforms. At the moment’s motion due to this fact has a broader impression, benefiting customers past Microsoft. Particularly, Microsoft’s Digital Crimes Unit disrupted:
- Hotmailbox.me, an internet site promoting fraudulent Microsoft Outlook accounts
- 1stCAPTCHA, AnyCAPTCHA, and NoneCAPTCHA, web sites that facilitate the tooling, infrastructure, and promoting of the CAPTCHA remedy service to bypass the affirmation of use and account setup by an actual particular person. These websites offered identification verification bypass instruments for different know-how platforms
- The social media websites actively used to market these companies

Microsoft is dedicated to offering a secure digital expertise for each particular person and group on the planet. We work carefully with Arkose Labs to deploy a next-generation CAPTCHA protection answer. The answer requires each would-be consumer who needs to open a Microsoft account to characterize that they’re a human being (not a bot) and confirm the accuracy of that illustration by fixing numerous sorts of challenges.
As founder and CEO of Arkose Labs, Kevin Gosschalk says: “Storm-1152 is a formidable foe established with the only real goal of making a living by empowering adversaries to commit complicated assaults. The group is distinguished by the truth that it constructed its CaaS enterprise within the gentle of day versus on the darkish internet. Storm-1152 operated as a typical web going-concern, offering coaching for its instruments and even providing full buyer help. In actuality, Storm-1152 was an unlocked gateway to critical fraud.”
Storm-1152’s exercise not solely violates Microsoft’s phrases of companies by promoting fraudulent accounts, nevertheless it additionally purposely seeks to hurt clients of Arkose Labs and deceive victims pretending to be respectable customers in an try to bypass safety measures.

Figuring out the people and infrastructure behind Storm-1152
Our evaluation of Storm-1152’s exercise included detection, evaluation, telemetry, undercover check purchases, and reverse engineering to pinpoint the malicious infrastructure hosted in the US. Microsoft Risk Intelligence and Arkose Cyber Risk Intelligence Analysis unit (ACTIR) offered further information and insights to strengthen our authorized case.
As a part of our investigation, we had been capable of verify the identification of the actors main Storm-1152’s operations – Duong Dinh Tu, Linh Van Nguyễn (also called Nguyễn Van Linh), and Tai Van Nguyen – based mostly in Vietnam. Our findings present these people operated and wrote the code for the illicit web sites, printed detailed step-by-step directions on easy methods to use their merchandise by way of video tutorials and offered chat companies to help these utilizing their fraudulent companies.

Microsoft has since submitted a prison referral to U.S. legislation enforcement. We’re grateful for our partnership with legislation enforcement who can carry these seeking to hurt our clients to justice.
Our ongoing dedication to preventing cybercrime
At the moment’s motion is a continuation of Microsoft’s technique of taking goal on the broader cybercriminal ecosystem and focusing on the instruments cybercriminals use to launch their assaults. It builds on our enlargement of a authorized technique used efficiently to disrupt malware and nation-state operations. We have now additionally partnered with different organizations throughout the trade to extend intelligence sharing on fraud and additional improve our synthetic intelligence and machine studying algorithms that shortly detect and flag fraudulent accounts.
As we’ve mentioned earlier than, no disruption is full in at some point. Going after cybercrime requires persistence and ongoing vigilance to disrupt new malicious infrastructure. Whereas right this moment’s authorized motion will impression Storm-1152’s operations, we anticipate different menace actors will adapt their strategies in consequence. Continued private and non-private sector collaboration, like todays with Arkose Labs and U.S. legislation enforcement, stay important if we need to meaningfully dent the impression of cybercrime.
