Infostealer intelligence has become one of the important tool in cybersecurity as malware has become one of the most efficient tools in a cybercriminal's kit. A single infected laptop can leak saved passwords, browser cookies, autofill data, and enough machine details for an attacker to impersonate the user outright. Stolen session cookies are especially damaging because they let intruders skip multi-factor authentication entirely. That makes the choice of an intelligence vendor in this space an operational decision, not a box-checking exercise. 

Top 10 Infostealer Intelligence Vendors 

1. Cyble

Cyble is a preferred vendor for organizations that want infostealer data inside a broader threat intelligence workflow rather than as a standalone feed. Its Cyble Vision platform combines compromised credential monitoring with dark web surveillance, brand protection, and attack surface management, so a leaked employee login can be connected to related exposure elsewhere.   The company's research arm, Cyble Research and Intelligence Labs, publishes regular analysis of new stealer families and campaigns. For teams that need context across several threat categories in a single console, Cyble is a strong starting point. Buyers focused narrowly on deep machine-level forensics should test that capability directly during a trial.

2. Flare

Flare is a full CTI platform that treats stealer logs as a core dataset rather than an add-on. Its interface is one of the cleanest in the category, which lowers the learning curve for analysts. Coverage of stealer logs is broad, and the platform provides solid details about infected machines.

3. SpyCloud

SpyCloud focuses on identity threat protection and is particularly strong on session data. It tracks stolen cookies and helps organizations invalidate compromised sessions before attackers can use them. That focus makes it a natural fit for teams worried about MFA bypass. Its free public tooling is more limited than some competitors'.

4. Breachsense

Breachsense takes an API-first approach to dark web and stealer-log monitoring. Its backend is consistent and well-documented, which appeals to teams that plan to pipe alerts directly into a SIEM or SOAR rather than work in a vendor's dashboard.

5. Lunar (Webz.io)

Lunar is built on Webz.io's web data infrastructure and stands out for generous free access to compromised-credential monitoring. Smaller organizations can get meaningful visibility without a large contract. Its API is less mature than those of the leaders, so heavy integration work may take more effort.

6. SOCRadar

SOCRadar positions itself as an extended threat intelligence provider, and its infostealer data sits alongside external attack surface monitoring and digital risk protection. Machine context is a notable strength. Teams looking for a specialist tool may find the platform's breadth more than they need.

7. Constella Intelligence

Constella approaches infostealers through the lens of identity risk, drawing on a large repository of breach and exposure records. Session tracking and API capabilities are both well regarded, which makes it useful for fraud prevention and account takeover defense.

8. Recorded Future

Recorded Future is one of the best-known names in threat intelligence. Infostealer data is one module among many in its intelligence platform. Machine context and API quality are strong, though session-level detail trails the more focused vendors. Organizations already using Recorded Future for other intelligence may find it convenient to extend coverage here.

9. NordStellar

NordStellar comes from Nord Security, the company behind NordVPN. It has gained ground quickly, with strong session coverage and good machine context. It is a relatively new entrant, so buyers should weigh its fast development pace against a shorter track record.

10. KELA

KELA specializes in cybercrime intelligence gathered from underground forums and marketplaces. Its infostealer coverage benefits from that vantage point, and session tracking is solid. Machine context and API depth are moderate compared with the vendors ranked above it. 

What Buyers Should Take Away 

No single vendor wins on every measure. Teams that want infostealer intelligence connected to wider threat monitoring will find Cyble, Flare, and SOCRadar worth a close look. Those focused on stopping account takeover should prioritize session capabilities, where SpyCloud, Constella, and NordStellar perform well. Engineering-heavy teams should put API quality near the top of their criteria, which favors Breachsense and Recorded Future.  Whatever the shortlist, two capabilities deserve extra weight. The first is session coverage, because cookie theft is now a routine way to defeat MFA. The second is machine context, because knowing exactly which device was compromised determines how quickly a team can contain the damage. A trial run against a known set of exposed accounts remains the most reliable way to see how a vendor performs in practice.  (Disclaimer: This article is based on third-party research and publicly available information, credited where applicable.

A text message about an unpaid traffic challan could cost Android users in India far more than a fine. GhostBat RAT, an Android malware strain first identified by cybersecurity firm Cyble in October 2025, has evolved to capture PINs from 60 banking, UPI apps, wallet and fintech applications, according to new research published by Cyble. The firm's investigation into fake mParivahan and eChallan apps also exposed a wider operator-controlled ecosystem it tracks as GhostX, linking phishing pages, backend control systems and malware distribution.

How GhostBat RAT Reaches Victims

The malware spreads mainly through smishing, or SMS phishing. Victims receive messages with malicious links that lead to pages impersonating the official Parivahan service or a Google Play-style download page. These pages push users to install a fraudulent mParivahan APK. Researchers also found GitHub repositories being repeatedly used to host the malicious files. Many of these apps are only first-stage loaders. The real payload stays hidden in encrypted files or is downloaded later, which makes the app look harmless during an initial scan. [caption id="attachment_114830" align="aligncenter" width="600"] GhostBat-RAT-Infection-Chain-1536x595[/caption]

GhostBat RAT's Ghost Overlay Trick

The most significant change in the latest variant is its abuse of Android's Accessibility Service, a technique commonly linked to modern Android banking trojan families. Earlier variants analyzed by Cyble did not have this capability. Its standout feature, called Ghost Overlay, targets Google Pay and MobiKwik. Instead of showing a fake login screen, the malware places an invisible 12-key grid over the real PIN keypad. When a user taps a digit, the overlay records it and then replays the same tap into the genuine app. The payment goes through normally, so the victim has no visible reason to suspect anything, while the PIN is quietly sent to the attackers' server.

GhostBat RAT Watches 60 Financial Apps

Beyond Google Pay and MobiKwik, a broader keylogging feature monitors 60 financial apps. Cyble's list includes PhonePe, Paytm, BHIM, SBI UPI, Axis Pay, BharatPe, CRED, Freecharge, PayZapp, Groww, Navi, Jupiter, OneCard, JioFinance and Samsung Pay. The malware checks which app is open and the screen context before treating numeric input as a possible PIN. This builds on older capabilities that remain in play, including reading SMS messages and OTPs, manipulating call forwarding, collecting call logs and sending SMS messages through the victim's SIM card, which could be used to spread further smishing campaigns.

Inside the GhostX Network Behind GhostBat RAT

A key finding came from an exposed Firebase backend named "ghostx-panel." It contained administrator records, user roles, login logs with device fingerprints and bot-user mappings. Cyble says these separate roles point to a multi-operator setup and raise the possibility of a Malware-as-a-Service model. While monitoring the backend, researchers saw SMS lure text, phishing links, vehicle registration numbers and recipient phone numbers changing repeatedly, indicating an active campaign. Matching eChallan messages were also reported by users on social media.

Why GhostBat RAT Is Hard to Detect

Cyble identified at least six different loader designs. The newest, built around a native library called libnetbridge.so, passes the payload through several layers of encryption, compression and custom packaging before the final app appears. Security tools that scan only the outer APK are unlikely to catch it consistently. The malware also uses Firebase Remote Config, which lets operators switch command servers and turn features on or off remotely without pushing a new app to victims.

Staying Safe From GhostBat RAT

Cyble advises users to install apps only from official stores such as Google Play and to avoid APK links received by SMS, social media or email. Users should be cautious about granting app permissions, especially Accessibility access, verify website addresses before entering sensitive details, enable multi-factor authentication on financial apps and keep their phones updated. Anyone who suspects infection should contact their bank and local authorities immediately.

A text alert about an undelivered package or an unpaid toll may look like a one-off scam. A new Microsoft cybercrime crackdown shows it is often the visible end of a much larger operation. Microsoft and Health-ISAC, a global non-profit that helps health sector organizations share cyber threat information and improve operational resilience, have moved to dismantle three services, YAM Store, CoGUI and Iron Man, that supplied criminals worldwide with accounts, hosting and tools to build fake websites and online identities. Since January 2026, the three services have collectively enabled more than one billion malicious messages targeting over 75,000 organizations worldwide. More than 750 million of those messages were aimed at Microsoft customers alone. Consumers, healthcare organizations, financial institutions and other businesses in more than 150 countries were targeted, generating tens of millions of dollars for the operators.

How the Microsoft Cybercrime Crackdown Began

The investigation started in late 2025 after Japan's National Police Agency (NPA) alerted Microsoft to malicious messaging campaigns targeting people in Japan. The NPA continued providing intelligence and investigative support throughout the probe as partners traced those campaigns back to the businesses supplying criminals around the world. Investigators expected to find individual campaigns. Instead, they traced the activity to a sprawling Chinese-language marketplace that was difficult for non-native-speaking investigators to penetrate. The probe widened to include the Japan Cybercrime Control Center (JC3), Resecurity, Cloudflare, Oracle, Proofpoint and TRM Labs. Drawing on its network of more than 130 member organizations, JC3 linked what appeared to be separate incidents into a broader pattern of scams against Japanese companies and financial institutions. Health-ISAC provided insight into the impact on healthcare organizations.

What the Microsoft Cybercrime Crackdown Uncovered

YAM Store operated much like an online shop. Customers could browse products, compare prices and buy fraudulent Microsoft and Google accounts along with ready-made scam tools, including those used for credential theft. Controlled purchases by Microsoft helped confirm how it worked. In some cases, operators bought internet domains that legitimate organizations had allowed to expire, often in sectors such as non-profits and education, with specialized product offerings for those sectors. They rebuilt the websites to make those organizations appear active, then used them to fraudulently obtain Microsoft 365 accounts for resale. The infrastructure sold through YAM Store was frequently paired with CoGUI. This service supplied ready-made websites and messages impersonating companies, banks, government agencies and other trusted organizations. Rather than build fraudulent sites themselves, criminals could quickly deploy pages designed to steal passwords, payment details and personal data. CoGUI became one of the most widely used offerings in the ecosystem, particularly targeting victims in Japan and the United States. [caption id="attachment_114817" align="aligncenter" width="600"] Image Source: https://blogs.microsoft.com/[/caption] By mid-2026, CoGUI was increasingly being replaced by Iron Man, which offered thousands of phishing templates tailored to specific brands, industries and countries. Criminals could use them to quickly deploy email, text and web content. Through test purchases and work with Resecurity, investigators identified more than 2,300 templates impersonating banks, retailers, healthcare providers, transportation authorities, police departments and government agencies across more than 150 countries. Others mimicked airlines, telecommunications companies and parcel delivery services. Some were built for government impersonation scams, using the look of official authority to pressure victims into paying or sharing sensitive information. Microsoft noted that an organization appearing in these templates does not mean its systems were compromised.

Court Order Backs Microsoft Cybercrime Crackdown

Acting on an order from the United States District Court for the Southern District of Florida, Microsoft and Health-ISAC seized and redirected domains that formed part of the infrastructure behind the three services. Microsoft has disabled more than 20,000 accounts linked to YAM Store and is blocking more than 100,000 domains used for impersonation and fraud, while removing infrastructure hosted on its services. Microsoft also shared intelligence with the U.S. Secret Service and international law enforcement partners. Investigators used AI tools to connect accounts, websites and infrastructure that initially appeared unrelated. The case reflects a trend highlighted in this year's Microsoft Digital Defense Report: modern fraud increasingly relies on businesses and services that help criminals reach more victims. No single organization saw the full picture of this transnational cybercrime network, and uncovering it required two-way information sharing across industries and borders. YAM Store, CoGUI and Iron Man are only part of a larger criminal ecosystem. Still, the Microsoft cybercrime crackdown makes it harder for criminals to obtain the accounts, tools and infrastructure that keep scam messages flowing. Microsoft Threat Intelligence has published a blog with further details on the network and steps customers can take to protect themselves.

X has suspended more than 13,000 accounts tied to three suspected foreign influence operations linked to Iran, Russia, and China. With the US midterms approaching, the platform said the fake X accounts were trying to shape political debate in the United States. The crackdown came one week after OpenAI announced it had disrupted two similar influence campaigns from Russia and Iran.  The company announced the suspensions on Wednesday while outlining its plans for the November 3 US midterm elections. According to X, its investigations found that the networks used fake accounts to publish and amplify political content aimed at candidates and public figures "across the political spectrum." 

Fake X Accounts Targeted Candidates Across Party Lines 

X said it detected the accounts through "proactive sweeps and investigations" carried out under its rules against spam and coordinated inauthentic behaviour.  In a statement on the suspensions, X Global Government Affairs said: "Free speech is the bedrock of a functioning democracy, and we are proud that X is the global town square where these debates happen. Our job is to keep that conversation authentic, open, and safe."  Along with removing the fake X accounts, the platform set out its rules for the US midterms. These rules ban misleading information about how, when, or where to vote. They also cover attempts to suppress voter turnout and acts of voter intimidation, including calls for violence near polling stations.  Users who come across questionable election-related posts can report them through the "civic integrity" option and request a community note that adds context. In urgent cases, X said it may also label posts that break its election rules. 

OpenAI's Recent Action and X's Earlier Crackdowns 

X's announcement followed a similar move by OpenAI a week earlier. OpenAI said it had shut down two alleged influence operations from Russia and Iran that used ChatGPT to create fake journalist personas. One of the operations also ran a "think-tank" that covertly spread anti-Ukraine propaganda.  This is not the first time the platform has acted against suspected foreign networks. In 2021, Twitter, as X was then known, said it had suspended 238 accounts purportedly operating from Iran.  The latest suspensions are much larger than that earlier action. The actions by X and OpenAI also show that foreign influence efforts are now spread across several technology platforms, from social media networks to AI tools, as the US midterms draw closer. 

The OLVX marketplace, an illicit online platform used to sell stolen personal data, login credentials and cybercrime tools, has been dismantled following a coordinated investigation by North Macedonia’s Ministry of Interior and the US Federal Bureau of Investigation (FBI). Authorities have filed criminal charges against a 20-year-old suspect from the Tetovo area, alleging involvement in computer fraud, misuse of personal data and the production and distribution of child sexual abuse material. According to North Macedonia’s Ministry of Interior, the Cybercrime and Digital Forensics Sector submitted the charges against E.A., from the village of Golema Rečica, to the Basic Public Prosecutor’s Office in Tetovo. The investigation focused on the suspect’s alleged administration of the OLVX marketplace, which operated between 2023 and 2025. The operation began after the FBI provided intelligence that prompted a joint investigation into the platform and its associated criminal activities.

OLVX Marketplace Offered More Than 1,500 Stolen Login Credentials

Evidence gathered during the investigation indicated that the suspect administered domains and websites associated with OLVX between 2023 and 2025. The platform functioned as a cybercrime marketplace, where users could buy and sell stolen digital information, software tools and services intended to facilitate criminal activity. The marketplace primarily served cybercriminals seeking personal information and stolen login credentials that could provide access to victims’ online accounts and computer networks. During its operation, more than 1,500 sets of stolen login credentials were offered for sale, according to the authorities. The platform also used a cryptocurrency-based payment arrangement. Rather than operating an escrow service, as many underground marketplaces do, OLVX allowed users to load funds onto the site and use those funds to pay one another. The arrangement provided an alternative payment mechanism for transactions conducted through the platform.

Telegram Group Allegedly Offered Cybercrime Tools

The investigation also examined the suspect’s alleged activities on Telegram. Authorities said that between 2025 and 2026, the suspect administered an illicit online group called ONEMILI, which offered software tools and services designed to facilitate cybercrime. These included fraudulent refund schemes, according to the Ministry of Interior. Investigators also obtained evidence indicating that the suspect had acquired and possessed child sexual abuse material (CSAM) for personal use through Telegram. The allegations form part of the criminal charges filed with the prosecutor’s office. The available information does not specify whether the suspect has been arrested or whether court proceedings have begun.

FBI Investigation Highlights Cross-Border Cybercrime Enforcement

The operation marks the first jointly coordinated cybercrime operation between North Macedonia’s Ministry of Interior and the FBI, according to the ministry. The case demonstrates how intelligence sharing between law enforcement agencies can support investigations into online platforms operating across jurisdictions. Authorities have increasingly targeted illicit online marketplaces that facilitate the exchange of stolen information, cybercrime tools and tactics. Over the past five years, law enforcement agencies have taken down dozens of such marketplaces, which have become focal points for cybercriminals trading data and services. In a separate development, Microsoft announced the takedown of three popular Chinese phishing sites used by cybercriminals to send hundreds of millions of malicious messages impersonating more than 75,000 organizations worldwide. Although the cases involve different platforms and activities, both illustrate law enforcement and technology companies’ efforts to disrupt online infrastructure used for cybercrime. The North Macedonia investigation highlights the role of international cooperation in identifying platform administrators and disrupting services linked to the trade in stolen data. The Ministry of Interior said its Cybercrime and Digital Forensics Sector would continue working to combat cybercrime, protect personal data and improve digital safety.
