2025 Identity Threat Landscape Report: Inside the Infostealer Economy: Credential Threats in 2025
Sam Langrock and Dmitry Smilyanets · 2026-03-16 · via Recorded Future

Executive Summary

Credential theft is the dominant initial access vector for enterprise breaches. In 2025, Recorded Future detected:

  • 1.95 billion malware combo list credential exposures
  • 36 million database combo list credential exposures
  • 24 million database dump credential exposures
  • 892 million malware log credential exposures

Five findings stand out from the data:

  1. Credential theft accelerated as the year progressed. Recorded Future identified 50% more credentials in the second half of 2025 than in the first half of the year. 90% more credentials were identified in the last three months of the year than in the first three months
  2. Stolen credentials are targeted, not random. Of the 7 million credentials indexed with identifiable authorization URLs, 63.2% were tied to authentication systems. VPNs, RMM tools, cloud platforms, and detection software also featured prominently — meaning attackers are often going directly for the systems that provide the broadest access and, in some cases, the ability to blind security teams entirely.
  3. Infostealer malware is outpacing traditional breach detection. Each compromised device yielded an average of 87 stolen credentials. The scale and precision of modern infostealers means a single infected endpoint — including a personal device used to access corporate systems — can expose an entire organization.
  4. MFA alone is no longer sufficient protection. 276 million of the credentials indexed in 2025 included active session cookies, meaning attackers can bypass multi-factor authentication entirely. This represents 31% of all malware-sourced credentials.
  5. Detection speed is the decisive advantage. Over half of all credentials (53%) were indexed within one week of exfiltration, and 36.4% within 24 hours. Organizations that act on intelligence quickly can intervene before stolen credentials are exploited.

The Scale of the Problem: Compromised Credentials in 2025

Volume Grew Throughout the Year

Credential compromise from malware logs was not a static risk in 2025 — it compounded. Recorded Future observed a consistent upward trend throughout the year, with the second half producing 50% more indexed credentials than the first.

The final three months of the year were particularly active: They saw 90% more volume than the first three months, reflecting both the continued proliferation of infostealer malware-as-a-service (MaaS) and the disruption and reformation of major malware families mid-year (covered in detail in the malware section below).

What this means for security teams: Seasonal or quarterly threat reviews are insufficient. The volume and pace of credential exposure in 2025 demands continuous monitoring — not periodic audits.

What do Those Credentials Actually Unlock?

CHART 2: Top authorization URL categories, 2025 (Source: Recorded Future)

More credentials exposed means more doors open to attackers. The authorization URL data from 2025 reveals exactly which doors they're targeting — and the picture is stark.

Of the 7 million credentials with high-risk authorization URLs indexed in 2025, 63.2% were tied to authentication systems. The next largest categories were web content management (9.95%) and cloud computing (7.58%), followed by remote monitoring and management tools (6.19%) and email infrastructure (3.87%).

This is not a random distribution. Authentication systems, cloud platforms, and remote access tools — VPNs at 2.4% and RMM tools at 6.19% — are precisely the systems that give attackers the broadest foothold inside an organization. A single stolen credential for an authentication portal or VPN can serve as the entry point for lateral movement, privilege escalation, and ultimately a full breach.

The presence of detection and response software (1.17%) and SIEM platforms (0.06%) in this list is particularly notable. Credentials for the tools organizations rely on to detect attacks are themselves being stolen — giving attackers the ability to blind security teams before they strike.

What this means for security teams: The value of a stolen credential is determined by what it unlocks. Prioritize monitoring and rapid response for credentials tied to authentication systems, remote access tools, cloud infrastructure, and security platforms — these can represent the highest-leverage targets for attackers operating with stolen credentials.

A Global Problem With Regional Concentration

Compromised credentials were indexed from organizations across the globe. The ten countries with the highest credential volume in 2025 were:

The breadth of this data underscores that credential theft is not concentrated in a single region or industry — it is a universal risk. Organizations with global workforces, multinational supply chains, or international customer bases face exposure across multiple geographies simultaneously.

The Anatomy of a Compromise: What Attackers Actually Steal

87 Credentials Per Device

When an employee's device is infected with infostealer malware, the damage rarely stops at one account. In 2025, the average compromised device yielded 87 stolen credentials — spanning corporate applications, personal accounts, and cloud services accessed from the same machine.

Recorded Future's Compromised Host Incident Reports surface the full scope of each device-level infection, including the malware family responsible, file paths, IP addresses, and infection timelines. This context is what separates actionable intelligence from a list of leaked passwords.

What this means for security teams: A single alert should trigger a device-level incident response, not just a password reset. Understanding what else was on that machine — and what else may have been exfiltrated — is essential to containing the full extent of the exposure.

One of the most significant findings from 2025 is the volume of credentials that included active session cookies alongside stolen passwords. Recorded Future indexed 276 million credentials with cookies — 31% of all malware-sourced credentials — a figure that grew 30% from the first half of the year to the second half.

Session cookies allow attackers to authenticate as a user without entering a password or completing an MFA challenge. They effectively render secondary authentication controls irrelevant for as long as the session remains active.

December was the single highest month for cookie-bearing credential exposure, indexing 18% more than the next highest month (November).

What this means for security teams: MFA enrollment is necessary but not sufficient. Organizations should monitor for session cookie theft specifically, enforce shorter session token lifespans for high-risk applications, and treat any credential exposure from an infostealer log as a potential authentication bypass — not just a password reset trigger.

The Infostealer Ecosystem: How the Malware Landscape Shifted in 2025

LummaC2: The Year's Dominant Threat

LummaStealer emerged as the most widely deployed infostealer of 2025. Operating under a malware-as-a-service model since late 2022, it matured significantly over the past year, targeting Windows systems to harvest browser credentials, session cookies, cryptocurrency wallets, and two-factor authentication tokens.

Its distribution relied heavily on social engineering — fake software downloads and "ClickFix" techniques that trick users into executing malicious commands disguised as CAPTCHA challenges. Recent campaigns used CastleLoader for delivery, running obfuscated payloads in memory to evade detection.

In May 2025, a coordinated law enforcement action neutralized more than 2,300 LummaC2 command-and-control domains. The disruption was significant — but not fatal. LummaStealer operators migrated to bulletproof hosting services and employed sophisticated sandbox evasion techniques, including trigonometric analysis of mouse movements to avoid automated detection environments. Activity continued under private, select-affiliate operations through the remainder of the year.

How the Rest of the Ecosystem Responded

The 2025 infostealer landscape was shaped as much by law enforcement disruption as by attacker innovation. Each takedown created a vacuum that other malware families quickly filled.

Early 2025: The late-2024 law enforcement actions against RedLine and META pushed users toward emerging MaaS alternatives, consolidating volume around LummaC2 and accelerating its dominance through Q2.

Mid-2025: Following the LummaC2 disruption in May, established families — Rhadamanthys, Vidar, and StealC — absorbed the displaced activity. Rhadamanthys led through the summer until its own infrastructure was taken down by law enforcement in November 2025. Vidar stepped into the lead position thereafter.

Rebranding as a survival strategy: Disruption prompted reinvention. StealC relaunched as StealC v2. Vidar operators attempted a similar rebrand. These moves reflect a deliberate effort by malware developers to obscure continuity and frustrate attribution.

macOS: Atomic macOS Stealer (AMOS) dominated the macOS market through most of 2025, disappearing in October before returning in February 2026. MacSync (formerly Mac.C) emerged as the primary commodity macOS infostealer by year end.

Private operations grew: Increased law enforcement pressure on publicly accessible MaaS tools pushed sophisticated threat actors toward private infostealers with restricted affiliate access. Acreed (also known as ACR Stealer) and Odyssey Stealer represented the most significant private-operation families of 2025. Private Lumma operations also continued post-disruption.

What this means for security teams: Malware family names change. Takedowns create temporary disruption, not permanent resolution. Organizations that track exposure by malware family rather than only by leaked credential volume will be better positioned to understand the true source and scope of each incident.

Recommendations for Security Teams

The 2025 data points to four areas where security teams can meaningfully reduce their exposure to credential-based attacks.

1. Extend monitoring to personal devices. The majority of infostealer infections occur on personal devices used to access corporate systems — a risk that endpoint detection tools and traditional perimeter controls cannot address. Monitoring infostealer malware logs directly provides visibility into these exposures before they are weaponized.

One large automotive parts distributor found that Recorded Future surfaced stolen credentials tied to an employee's personal device — an exposure their existing tools had no visibility into and would likely never have caught.

2. Treat session cookie exposure as a critical-severity event. With 276 million credentials carrying active cookies in 2025, any infostealer-sourced credential exposure should trigger immediate session invalidation in addition to a password reset. MFA bypass via stolen cookies is not a theoretical threat — it is an observed, frequent attack pattern.

3. Automate response workflows to close the detection-to-remediation gap. The data shows that most credentials are indexed within days of theft. Organizations that have pre-built response playbooks — automatically checking Active Directory, clearing sessions, forcing resets, and notifying managers — respond in minutes rather than hours.

"We created a custom SOAR playbook using the Identity Intelligence module. This playbook takes the information of compromised corporate user accounts, runs an Active Directory check for the credentials, clears user sessions and resets the password if the account is found to be compromised. It also notifies the user's manager for email response. To date, we have processed over 330 different identity alerts. " — Bryan Cassidy, Lead Cyber Defense Engineer, 7-Eleven (UserEvidence)

4. Monitor your entire domain footprint — including subsidiaries and third parties. Some of the most consequential exposures in 2025 involved obscure subsidiaries and supply chain partners, not core corporate domains. Attackers do not limit themselves to obvious targets. Security teams shouldn't limit their monitoring to obvious domains either.

One large international financial services firm detected an infostealer on a third-party service provider's machine through Recorded Future — surfacing a supply chain exposure that would have been invisible through traditional monitoring alone.

The Recorded Future Advantage: Detection Speed – From Exfiltration to Alert in Hours

The gap between when credentials are stolen and when a security team finds out is where breaches happen. Most organizations discover compromised credentials days or weeks after the fact — through a public breach disclosure, a tip from law enforcement, or an incident that's already underway.

Recorded Future closes that gap. In 2025, 36.4% of all indexed credentials were detected within 24 hours of exfiltration, and 52.9% within one week. By the time stolen credentials are being traded or weaponized, Recorded Future customers have already been alerted.

Credential Exfiltration Breakdown

Speed matters because attackers move fast. Infostealer logs are often listed for sale within hours of collection. Every day between exfiltration and detection is a day an attacker may already have access. The 15.3% of credentials not detected within a month illustrate what happens when that window stays open — extended attacker dwell time, lateral movement, and incidents that escalate into major breaches.

For Recorded Future customers, early detection is only half the equation. Pre-built integrations with Okta, Microsoft Entra ID, and SOAR platforms like XSOAR mean that when a credential alert fires, automated workflows can clear sessions, force password resets, and notify managers — without waiting for an analyst to pick up the ticket.

A large international financial services firm's Team Lead described a recent credential leak: identified and escalated in under 24 hours, triggering immediate automated remediation — exactly the outcome their team had built toward.

Appendix: Notable Passwords from 2025 Credential Exposures

The following passwords appeared most frequently across credentials indexed by Recorded Future in 2025. Their prevalence reflects the continued gap between password policies and actual user behavior — and the reason why credential monitoring cannot rely on password complexity alone as a proxy for risk.
