THE MALWARE ENTERPRISE THREAT
The reality of enterprise malware risk
False Sense of Security
Traditional defenses aren't stopping infostealers
EDR and antivirus tools are essential – but they don’t defend you fully. Infostealers are specifically engineered to evade detection, execute rapidly, and disappear before endpoint tools can flag them. By the time a scan fires, the data is already in criminal hands.

Data Weaponization
A single infection gives criminals a multi-pathway attack kit
Stolen credentials, session cookies, and tokens don’t just unlock one door, they open entire enterprise environments. SpyCloud recaptures this data from the underground before it’s weaponized against your organization.

Take Action Now
Post-infection remediation isn't optional – it's urgent
After a malware infection, the clock is ticking. Without immediate remediation of all exposed identities, attackers have everything they need to launch account takeover, commit fraud, or establish persistent access before you’ve even opened the incident ticket.
Malware's role in the modern identity attack chain
Every infostealer infection is the starting gun for a chain of identity-based threats. Here’s how attackers move from device to damage.

USE CASES
Put our malware intelligence to work
SpyCloud’s recaptured data powers a broad range of security and fraud prevention use cases – all from a reliable source of underground truth. Up-level your defenses with trusted malware intelligence from our platform.
Automate identity exposure remediation
Automatically invalidate stolen sessions, reset compromised credentials, and trigger remediation workflows before attackers can exploit what malware has already stolen.
Prevent authentication bypass
Prevent ransomware
Cut off the initial access pathway. Ransomware operators rely on stolen credentials to establish footholds. SpyCloud intelligence disrupts the attack before it escalates.
Detect insider threats
Identify employees whose devices and credentials have been compromised by malware, enabling rapid response to insider risk driven by external infection.
Remediate supply chain threats
Monitor third-party and vendor exposure. When a supplier’s credentials appear in stealer logs, you’ll know before the threat reaches your environment.
Power Zero Trust policies
Feed real-time compromised identity signals into your Zero Trust architecture to continuously validate access decisions based on actual threat intelligence.

Malware intelligence FAQs
SpyCloud Workforce Threat Protection monitors employee and contractor credentials across four distinct data sources recaptured from criminal infrastructure. Third-party breach data covers credentials from breaches at companies where employees registered with work email addresses, including breach source details and plaintext passwords. Infostealer malware logs cover credentials exfiltrated from infected employee and contractor devices, along with session cookies, device fingerprints, and application access data captured in the same infection. Phishing capture data covers credentials harvested during successful phishing attacks targeting employee accounts, surfaced from captured phishing kit output before those credentials circulate widely in criminal markets. Combolists cover repackaged credential sets that aggregate multiple breach and malware sources into new attack-ready lists. SpyCloud continuously ingests and processes more than 25 billion pieces of stolen identity data every month, with new data typically published within days of appearing in criminal markets well before it reaches breach notification services or public indexes. The practical difference is that SpyCloud customers see exposures in hours to days rather than the weeks to months that follow typical breach disclosure timelines.
Standard dark web monitoring and breach notification services identify credential exposures by scanning indexable portions of dark web forums and marketplaces, or by receiving notifications when a breach is publicly disclosed. Both approaches depend on data that is already publicly or semi-publicly available — which means it arrived in criminal markets weeks or months before the monitoring service found it. SpyCloud infiltrates criminal communities directly and recaptures stolen identity data from the source before it enters the wider criminal ecosystem. This includes infostealer malware logs, which are distributed through private criminal channels and rarely indexed by dark web scanners, and phishing kit output, which is captured before credentials from a phishing campaign have been aggregated and resold. SpyCloud’s recaptured dataset now contains 65.7 billion distinct identity records. Beyond data freshness and scope, SpyCloud’s IDLink analytics extend monitoring to employees’ personal identity footprints — surfacing exposures tied to personal email addresses and personal accounts that share password patterns with corporate accounts. This produces 14 times more plaintext passwords per user compared to exact-match monitoring against the corporate domain alone, catching the password reuse attack path that breach notification services structurally cannot see.
Workforce Threat Protection is an intelligence and detection layer, not a replacement for IAM tools. Okta and Azure AD manage identity lifecycle, access policy, and authentication. They operate on internal signals — login events, access requests, policy violations inside the corporate environment. They have no visibility into what is happening in criminal markets with employee credentials outside the corporate perimeter. Workforce Threat Protection fills that gap by continuously monitoring criminal sources for exposures tied to employee identities and delivering actionable exposure alerts. Those alerts then feed directly into IAM workflows: Workforce Threat Protection integrates with Okta, Entra ID, and Active Directory to trigger automated remediation when a match is confirmed. For organizations using Identity Guardians, the automated response is a forced password reset or session revocation executed within minutes of detection. For organizations using SIEM or SOAR, the exposure data enriches alert queues and feeds automated playbooks. The relationship is additive: IAM tools manage the authentication layer while Workforce Threat Protection monitors the criminal underground for what attackers already know about that layer.
Workforce Threat Protection and Endpoint Threat Protection both use SpyCloud’s recaptured darknet data, but they address different scopes of the identity exposure problem. Workforce Threat Protection monitors employee and contractor credentials across the corporate domain against breach, malware, and phishing data, and surfaces the credential-level exposure: which employees have compromised passwords, from which source, and with what recency. It answers the question of who is exposed and triggers credential hygiene remediation. Endpoint Threat Protection goes deeper into the device-level impact of infostealer infections specifically. When a device is infected, an infostealer exfiltrates not just credentials but also session cookies, browser autofill data, PII, device fingerprints, and the full inventory of every application accessed from that device. Endpoint Threat Protection surfaces the cookie count, application exposure scope, and PII from each infected device — the full blast radius of the infection rather than just the credential portion. Most security programs benefit from both. Workforce Threat Protection provides continuous credential hygiene across the entire workforce. Endpoint Threat Protection handles the deeper investigation and response when a specific infostealer infection is confirmed and the full scope of what was exfiltrated needs to be understood before remediation is complete.
SpyCloud’s data processing pipeline is designed to minimize the window between when stolen credentials appear in criminal sources and when security teams can act on them. Breach data and phishing captures are typically published in the SpyCloud platform within days of being recaptured from criminal sources. Infostealer malware logs, which circulate through more private criminal channels, are processed within hours to days of SpyCloud recapturing them. The practical effect is that security teams learn about employee credential exposures in the same timeframe that criminal operators are acquiring and testing that data — often before the data has been weaponized in a targeted attack. A financial services company using Workforce Threat Protection reported discovering anywhere from 3,000 to 11,000 direct credential matches per hour at peak. Each of those represents an account that could have led to account takeover before Workforce Threat Protection surfaced the exposure. The alternative — waiting for a breach notification that arrives weeks or months after the data has been in criminal hands — leaves an extended window during which attackers with access to the same data can test credentials against corporate login portals without any detection.
