At Microsoft, we proceed to search for artistic methods to guard folks on-line and that features having no tolerance for many who create fraudulent copies of our merchandise to hurt others. Fraudulent on-line accounts act because the gateway to a bunch of cybercrime, together with mass phishing, identification theft and fraud, and distributed denial of service (DDoS) assaults. That’s the reason right now, we, with invaluable risk 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 prospects.
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 expertise platforms. These providers cut back the effort and time wanted for criminals to conduct a bunch of legal and abusive behaviors on-line. To this point, Storm-1152 created on the market roughly 750 million fraudulent Microsoft accounts, incomes the group tens of millions of {dollars} in illicit income, and costing Microsoft and different firms much more to fight their legal exercise.
With right now’s motion, our aim is to discourage legal habits. By looking for to sluggish the pace at which cybercriminals launch their assaults, we purpose to boost their price of doing enterprise whereas persevering with our investigation and defending our prospects and different on-line customers.
How cybercriminals use Storm-1152’s providers
Storm-1152 performs a major position within the extremely specialised cybercrime-as-a-service ecosystem. Cybercriminals want fraudulent accounts to help their largely automated legal actions. With firms in a position to rapidly determine and shut down fraudulent accounts, criminals require a better amount of accounts to avoid mitigation efforts. As an alternative of spending time making an attempt to create hundreds of fraudulent accounts, cybercriminals can merely buy them from Storm-1152 and different teams. This permits criminals to focus their efforts on their final objectives of phishing, spamming, ransomware, and different varieties 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, knowledge theft and extortion which have used Storm-1152 accounts. For instance, Octo Tempest, often known as 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 aim of monetary extortion. Microsoft continues to trace a number of different ransomware or extortion risk actors which have bought fraudulent accounts from Storm-1152 to reinforce their assaults, together with Storm-0252 and Storm-0455.
Our disruption technique
On Thursday, December 7, Microsoft obtained a courtroom 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 prospects. Whereas our case focuses on fraudulent Microsoft accounts, the web sites impacted additionally offered providers to bypass safety measures on different well-known expertise platforms. In the present day’s motion subsequently has a broader influence, 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 resolve service to bypass the affirmation of use and account setup by an actual particular person. These websites offered identification verification bypass instruments for different expertise platforms
- The social media websites actively used to market these providers

Microsoft is dedicated to offering a protected digital expertise for each particular person and group on the planet. We work carefully with Arkose Labs to deploy a next-generation CAPTCHA protection resolution. The answer requires each would-be person who needs to open a Microsoft account to signify that they’re a human being (not a bot) and confirm the accuracy of that illustration by fixing varied varieties of challenges.
As founder and CEO of Arkose Labs, Kevin Gosschalk says: “Storm-1152 is a formidable foe established with the only real function of being profitable by empowering adversaries to commit advanced assaults. The group is distinguished by the truth that it constructed its CaaS enterprise within the mild 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 severe fraud.”
Storm-1152’s exercise not solely violates Microsoft’s phrases of providers by promoting fraudulent accounts, nevertheless it additionally purposely seeks to hurt prospects of Arkose Labs and deceive victims pretending to be reputable customers in an try and bypass safety measures.

Figuring out the people and infrastructure behind Storm-1152
Our evaluation of Storm-1152’s exercise included detection, evaluation, telemetry, undercover take a look at purchases, and reverse engineering to pinpoint the malicious infrastructure hosted in the US. Microsoft Risk Intelligence and Arkose Cyber Risk Intelligence Analysis unit (ACTIR) supplied further knowledge and insights to strengthen our authorized case.
As a part of our investigation, we have been in a position to verify the identification of the actors main Storm-1152’s operations – Duong Dinh Tu, Linh Van Nguyễn (often known as Nguyễn Van Linh), and Tai Van Nguyen – primarily based in Vietnam. Our findings present these people operated and wrote the code for the illicit web sites, printed detailed step-by-step directions on tips on how to use their merchandise through video tutorials and supplied chat providers to help these utilizing their fraudulent providers.

Microsoft has since submitted a legal referral to U.S. legislation enforcement. We’re grateful for our partnership with legislation enforcement who can deliver these seeking to hurt our prospects to justice.
Our ongoing dedication to preventing cybercrime
In the present day’s motion is a continuation of Microsoft’s technique of taking purpose on the broader cybercriminal ecosystem and focusing on the instruments cybercriminals use to launch their assaults. It builds on our enlargement of a authorized methodology used efficiently to disrupt malware and nation-state operations. We now have additionally partnered with different organizations throughout the business to extend intelligence sharing on fraud and additional improve our synthetic intelligence and machine studying algorithms that rapidly detect and flag fraudulent accounts.
As we’ve mentioned earlier than, no disruption is full in sooner or later. Going after cybercrime requires persistence and ongoing vigilance to disrupt new malicious infrastructure. Whereas right now’s authorized motion will influence Storm-1152’s operations, we count on different risk 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 influence of cybercrime.
