TL,DR:
- Infostealer malware and phishing attacks capture credentials and session cookies to bypass traditional defenses like MFA, allowing attackers to hijack accounts for follow-on attacks like ransomware and fraud.
- Visibility gaps from unmanaged devices, shadow IT, and third-party vendors require a shift to identity-focused security that monitors exposures beyond the corporate perimeter.
- Security teams must integrate dark web identity intelligence with IAM and SOAR tools to automate the immediate remediation of compromised credentials and active sessions.
As 2026 unfolds, CISOs face an unprecedented convergence of challenges including AI-accelerated attacks, identity sprawl, and tightening budgets. We’ve identified the concerns keeping security leaders up at night and how dark web intelligence can help you stay ahead.
Here, we explore the top concerns shaping security agendas, and tips for adopting actionable strategies rooted in identity threat intelligence.
The evolving threat landscape: Malware, phishing, and session hijacking
The threat landscape is evolving rapidly, driven by infostealer malware that captures credentials, session cookies, refresh tokens, and more for immediate exploitation. This shift moves beyond simple credential theft to include sophisticated authentication bypass techniques. CISOs must now contend with attackers who can bypass traditional defenses like MFA with ease.
Why infostealer malware is the fastest-growing attack vector
Infostealer malware is designed to be undetectable while extracting credentials, web session cookies, PII, and other sensitive data from a user’s device. This data is then used to launch account takeover (ATO), ransomware attacks, authentication bypass, and more. Today’s malware incident response must shift from a device-focused to an identity-focused approach.
How criminals weaponize stolen credentials and session cookies
Bad actors use stolen data from malware logs and phishing attacks to impersonate legitimate users and move laterally within a network.
- Stolen credentials are used for ATO and privilege escalation.
- Stolen session cookies and refresh tokens are used to bypass MFA and hijack active accounts.
- Exfiltrated PII is leveraged for fraud and targeted social engineering.
From phishing to business email compromise: the social engineering evolution
Social engineering tactics are growing more sophisticated. Bad actors use stolen credentials to masquerade as executives in business email compromise (BEC) attacks.
The human factor: Why employees remain one of CISOs' biggest security challenges
The human element remains a primary factor in security incidents, with Verizon’s latest Data Breach Investigations Report citing it in 60% of breaches. Risky behaviors create significant blind spots for security teams and open doors for criminals. These behaviors go beyond falling for social engineering tricks.
Key human-related risks include:
- Using under-managed work devices that are not current on security policies
- Accessing corporate data from unmanaged personal devices
- Employing unapproved applications, also known as “shadow IT”
Detecting unwitting insider threats through dark web monitoring
Most insider threats are unwitting, not malicious. When an employee’s personal credentials are stolen from a third-party service, criminals can reuse them to target corporate systems. Dark web intelligence surfaces these hidden risks before they are weaponized.
Visibility gaps: shadow IT, unmanaged devices, and exposed cloud applications
Remote work and cloud adoption expand the attack surface, creating more blind spots. CISOs must gain visibility into these key areas to protect the enterprise. Just one exposed SSO credential can give criminals incredible access to corporate data.
Common visibility gaps include:
- Shadow IT: Unapproved applications and services that operate outside of security oversight.
- Unmanaged devices: Personal laptops and mobile devices accessing corporate data without proper security controls.
- Browser synchronization: Saved credentials and sessions synced across devices, including potentially infected personal machines.
Session hijacking: the post-password attack vector
Session hijacking is a critical threat that bypasses passwords and MFA entirely. Attackers use stolen session cookies, often exfiltrated by malware, to take over active user accounts in real time. This attack is frequently undetected by traditional security tools.
AI-driven attacks and identity exposure: The new CISO challenge
Generative AI has democratized sophisticated attack capabilities for criminals. They now use AI to automate and scale attacks with unprecedented efficiency. This creates a new class of threats that CISOs must address.
How criminals use AI to accelerate credential theft and fraud
Criminals leverage AI for a variety of malicious purposes, including:
- Crafting hyper-personalized phishing emails at scale.
- Automating credential stuffing attacks against login portals.
- Analyzing stolen data to identify high-value targets quickly.
- Creating deepfake audio or video for advanced BEC attacks.
Protecting identity data in the LLM era
Organizational adoption of AI tools like Large Language Models (LLMs) also creates new risks. Employees may inadvertently input sensitive PII or corporate data into unsecured AI applications. This can lead to data exposure if the AI tool is compromised or its data is used for training future models.
Identity and access management: From blind spot to strategic priority
CISOs now face a harsh reality: stolen credentials and session cookies can render traditional IAM controls moot. Identity management must evolve beyond simple access policies. It now requires continuous monitoring of identity exposures outside the corporate perimeter.
Why traditional IAM fails against stolen session cookies
Traditional IAM solutions are not built to detect when an authenticated session has been hijacked. Stolen session cookies allow attackers to bypass key defenses. These include:
- Multi-factor authentication (MFA)
- Password complexity and rotation policies
- Geofencing and IP-based access controls
Zero trust requires dark web intelligence
A true Zero Trust architecture assumes no user or device is inherently trustworthy. This requires verifying that an identity is not already compromised before granting access. Dark web intelligence is essential for a continuous Zero Trust approach that can validate that a user’s credentials have not been exposed – beyond login events.
Automation and alert fatigue: Helping SOC teams do more with less
With security budgets failing to keep pace, CISOs rely on automation to scale SOC capabilities without adding headcount. Alert fatigue from overwhelming alert volumes is a major challenge for these teams. Automation helps prioritize threats and reduce time spent on false positives.
Effective automation, however, is only as good as the data it acts on. High-fidelity intelligence is critical for SOC teams to trust automated actions. This allows them to focus on high-value projects instead of manual triage.
Key benefits of automating identity threat detection include:
- Reduced alert fatigue: Automatically surfacing and prioritizing the most critical threats.
- Faster remediation: Slashing Mean-Time-to-Remediate (MTTR) by triggering automated password resets or session invalidations.
- Increased efficiency: Enabling SOC teams to do more with less by handling repetitive tasks at machine speed.
That’s why automation is a key factor for SpyCloud customers like Atlassian, who use our solutions to automatically detect compromised identities and trigger remediation workflows.
Building cyber resilience through identity threat intelligence
Cyber resilience is about minimizing impact and accelerating recovery when breaches occur. For CISOs, this begins with knowing which identities are already compromised. Dark web intelligence provides an essential early warning system.
Identity exposures directly undermine an organization’s resilience.
- Stolen credentials and other authentication data: Enable attackers to gain initial access, move laterally, and escalate privileges undetected.
- Compromised identities: Increase attacker dwell time, allowing them to cause more damage before being discovered.
Automating recovery from credential compromise
Automating recovery is a cornerstone of modern resilience. By integrating dark web intelligence with IAM and SOAR platforms, teams can instantly trigger remediation playbooks. This includes forcing password resets and invalidating stolen session tokens within minutes of detection.
Supply chain security: Why vendor exposures are your problem
Your security is only as strong as your supply chain’s weakest link. Vendor and contractor identities represent high-risk entry points into your network. CISOs must extend identity exposure monitoring beyond their own workforce to the entire ecosystem.
When a third-party vendor’s employee credentials are stolen, attackers can use that access to pivot into your systems. This inherits your vendor’s security problems. Key risks include:
- Access to shared systems and sensitive data.
- Lateral movement from the vendor network into your own.
- Reputational damage from a breach originating with a partner.
Data protection in a breach-saturated environment
CISOs face a paradox of more data protection regulations but more breached data in circulation than ever. The challenge is not just preventing breaches, but detecting when your sensitive data has already been exfiltrated. This includes credentials, PII, and financial information being traded on the dark web.
Compliance pressures: How breach data impacts regulatory requirements
A complex web of regulations creates strict requirements for breach notification and data protection. When employee or customer credentials appear in a breach, CISOs must quickly determine if it is a reportable incident. Demonstrating due diligence is key.
Dark web intelligence helps CISOs meet mandates for regulations such as:
- GDPR (General Data Protection Regulation)
- CCPA (California Consumer Privacy Act)
- HIPAA (Health Insurance Portability and Accountability Act)
- PCI-DSS (Payment Card Industry Data Security Standard)
Proactive monitoring for exposed data helps establish ‘reasonable security measures’ and informs breach notification decisions. It allows CISOs to prove they are taking timely action to protect data, which is a critical component of compliance audits.
Addressing CISO concerns: An identity intelligence framework
The challenges above share a common thread: identity sprawl creates blind spots that fuel cyberattacks. CISOs need a framework that addresses threats at the identity layer where criminals operate. Here is how to integrate dark web intelligence into your security strategy:
- Prioritize identity-based risks. Use recaptured data from malware logs and breaches to identify the highest-risk exposures across your workforce, consumers, and supply chain.
- Automate detection and remediation. Implement automated workflows for credential resets, session invalidation, and alerting to reduce your Mean-Time-to-Remediate (MTTR).
- Integrate identity intelligence across your security stack.</ Feed dark web intelligence into your SIEM, SOAR, EDR, and IAM platforms to create a feedback loop between threat intelligence and security operations.
Addressing the top CISO concerns for 2026 requires a strategic shift toward protecting identities beyond the corporate perimeter. From AI-driven attacks to supply chain risks, the common thread is the exploitation of compromised credentials and session data. By integrating automated dark web intelligence, security leaders can move from a reactive to a proactive posture.
This approach provides the necessary visibility to close security gaps, build resilience, and protect the organization from the most prevalent modern threats. It transforms security from a source of concern to a source of confidence.
