Identity-Based Cyberattacks: The Biggest Threat in 2026
Share
Cybersecurity has always been a step ahead game. Defenders build controls, attackers find gaps, and the cycle continues. But something changed over the last couple of years. The rules of that game are no longer the same. Organizations spent years strengthening firewalls, patching vulnerabilities, and deploying endpoint protection. Yet, despite these investments, breaches are not slowing down. In fact, they are becoming faster, more targeted, and harder to detect.
The reason is simple. Attackers are no longer trying to break into systems. They are using legitimate access to move through them. According to the CyberProof 2026 Global Threat Intelligence Report, most major breaches in 2025 involved attackers posing as legitimate users rather than exploiting technical vulnerabilities . This marks a clear shift in attacker strategy. Instead of forcing entry, they are blending in. This shift is also backed by industry-wide data. The Sophos Active Adversary Report 2026 notes that nearly 75% of intrusions now involve compromised credentials, while multiple threat intelligence studies place identity-driven breaches between 67% and 75% of all incidents.
This article explains how cyberattacks have shifted from exploiting systems to abusing identities, making compromised credentials the most common entry point in modern breaches. It breaks down why identity-based attacks are rising, how they work, and what organizations need to do to detect and prevent them in 2026.
What Are Identity-Based Cyberattacks
Identity-based cyberattacks revolve around one central idea: if an attacker can convincingly appear as a legitimate user, most security controls will not stop them. This can happen in several ways. Attackers may steal credentials through phishing, capture session tokens from infected browsers, abuse OAuth permissions, or manipulate internal processes such as help desk workflows to reset access. In more advanced cases, they impersonate employees or IT staff and convince users to grant access voluntarily. The outcome is the same. The attacker gains valid access to systems without triggering traditional defenses.
This is what makes identity attacks different from earlier attack models. There is no obvious breach point. No broken firewall. No visible malware in many cases. Instead, the attacker operates inside the system as a trusted user.
Why Identity Attacks Have Become the Dominant Threat
The rise of identity-based attacks is not accidental. It is a direct result of how modern IT (Information Technology) environments are built and how attackers have adapted to those environments.
- Enterprise Environments Are Built Around Identity
Modern organizations rely heavily on identity-driven systems. Cloud platforms, SaaS applications, collaboration tools, and enterprise resource planning systems are all interconnected through identity layers. The CyberProof report highlights that attackers increasingly target ERP platforms, SaaS ecosystems, and identity services because compromising these systems provides immediate access to critical business functions and sensitive data .
This means a single compromised identity can open the door to multiple systems at once. Attackers no longer need to move step by step through a network. Access to one account can provide visibility across an entire environment.
- Credential-Based Access Enables Faster Attacks
Traditional attacks required time. Exploiting a vulnerability, establishing persistence, and moving laterally often took days or weeks. Identity-based attacks compress this timeline significantly. Once attackers obtain valid credentials, they can log in immediately, access systems, and begin extracting data or disrupting operations. This explains why modern breaches escalate so quickly. The attacker is not navigating defenses. They are bypassing them entirely.
- Human Trust Has Become a Security Weak Point
One of the most consistent findings across recent threat reports is the role of human behavior in enabling identity attacks. Help desk workflows, IT support processes, and internal approvals are designed for efficiency. They prioritize speed and user experience, not adversarial resistance. Attackers exploit this gap. The CyberProof report documents how impersonation of IT staff became one of the most effective attack methods in 2025. By convincing help desk teams to reset MFA tokens or grant remote access, attackers were able to gain control without exploiting any technical vulnerability . This approach works because it targets trust rather than technology.
- SaaS and OAuth Introduced New Attack Surfaces
Another major factor behind the rise of identity attacks is the widespread use of SaaS integrations and OAuth-based access. In several high-impact incidents, attackers did not exploit the core platform. Instead, they abused connected applications and tokens to gain access. The CyberProof report describes campaigns where attackers used OAuth integrations to access CRM systems across hundreds of organizations, exposing millions of records without directly interacting with the platform itself . This type of access is difficult to detect because it appears legitimate. The system sees a trusted application making authorized requests.
- AI Has Lowered the Barrier for Identity Attacks
Artificial intelligence has added a new dimension to identity-based threats. Attackers are using AI to generate convincing phishing emails, automate social engineering scripts, and even create adaptive malware. According to CyberProof, around 80% of ransomware campaigns incorporated AI at some stage of the attack lifecycle. AI is also expected to play a major role in the rise of deepfake-based impersonation attacks. Voice cloning and real-time impersonation are already being used in vishing campaigns, and this trend is expected to grow in 2026.
How Identity-Based Attacks Actually Work
Identity-based attacks follow a pattern that is simple in structure but highly effective in execution. Instead of breaking security controls, attackers work their way in by gaining trust and using that trust to expand access.
It usually starts with reconnaissance. Attackers identify employees who have access to critical systems, such as IT administrators, finance teams, or employees working with SaaS platforms. These users become the primary targets because compromising one high-privilege identity can open multiple systems at once.
The next step is initial access. This is where most identity attacks differ from traditional methods. Instead of exploiting software flaws, attackers rely on techniques like phishing, vishing, or impersonation. For example, an attacker may pose as an internal IT staff member and convince a help desk team to reset a password or approve a multi-factor authentication request. In other cases, they send carefully crafted emails that prompt users to enter credentials on a fake login page.
Once access is obtained, the attacker logs in as a legitimate user. At this stage, there are usually no alerts because the system sees a valid login attempt. This is what makes identity-based attacks difficult to detect. The attacker is not triggering alarms; they are blending into normal activity.
After gaining access, the attacker begins lateral movement. Using the same credentials or tokens, they move across systems, access connected applications, and explore the environment. In modern enterprise setups, where systems are interconnected through identity platforms, this movement can happen quickly and quietly.
The final stage depends on the attacker’s goal. Some focus on data exfiltration, extracting sensitive information such as customer data, financial records, or intellectual property. Others aim for operational disruption, targeting systems that affect business continuity. In many cases, the attack leads to extortion, where stolen data or disrupted operations are used to pressure the organization.
What stands out in this entire process is the minimal reliance on technical exploitation. The success of the attack depends more on access and trust than on breaking systems. That is why identity-based attacks are not only increasing but also becoming the most effective method used by modern threat actors.
Real-World Examples That Show the Shift
The shift toward identity-based attacks is not theoretical. It is visible in some of the most impactful incidents of recent years.
In the Salesforce ecosystem attacks, threat actors gained access by abusing OAuth integrations and connected applications rather than exploiting vulnerabilities. This allowed them to access customer data across multiple organizations at scale.
In the retail sector, attacks on companies such as Marks & Spencer, Co-op, and Harrods involved identity compromise through IT impersonation. Attackers were able to bypass multi-factor authentication by manipulating internal processes and gaining elevated access.
In the aviation sector, attacks on third-party service providers caused widespread disruption across multiple airports and airlines. These incidents showed how a single compromised identity within a shared ecosystem can affect multiple organizations simultaneously.
These examples highlight a common theme. The most damaging attacks are no longer the most technically complex. They are the ones that exploit trust, identity, and interconnected systems.
Why Traditional Security Models Are Struggling
Many organizations still rely on security models built around perimeter defense. Firewalls, intrusion detection systems, and endpoint protection are designed to stop external threats. Identity-based attacks bypass these controls entirely. Even multi-factor authentication, which is considered a strong defense, is not always enough. Attackers are finding ways to bypass MFA through social engineering, token theft, and session hijacking. The challenge is not just technological. It is structural. Security systems are not designed to question legitimate users, even when those users are compromised.
How Organizations Can Defend Against Identity-Based Attacks
Addressing identity-based threats requires a shift in how organizations approach security.
The first step is recognizing that identity is now the primary control plane. Security teams need to monitor not just whether access is granted, but how it is used. Behavioral analytics, continuous authentication, and anomaly detection become critical.
The CyberProof report emphasizes the need to treat identity assurance as a core security discipline, with continuous validation of user behavior and privilege use . Organizations also need to strengthen help desk and support workflows. Processes such as password resets and MFA changes should be treated as high-risk actions, with strict verification and monitoring.
SaaS and OAuth access must be closely managed. This includes auditing connected applications, limiting token permissions, and monitoring API activity for unusual behavior. Finally, organizations need to adopt a zero-trust approach. Instead of assuming that users inside the network are trustworthy, every access request should be verified based on context, behavior, and risk.
What to Expect in 2026
The trends observed in 2025 are expected to accelerate in 2026.
Identity-based attacks will continue to grow as organizations expand their use of cloud and SaaS platforms. AI-driven social engineering will become more sophisticated, making it harder to distinguish between legitimate and malicious interactions.
Deepfake-based impersonation is likely to become more common, especially in high-value targets such as finance and executive communications.
At the same time, attackers are expected to increasingly use regulatory pressure as part of their strategy, leveraging data breaches to trigger legal and reputational consequences for organizations.
To Sum Up
Identity has become the center of modern cybersecurity risk. Attackers no longer need to break through defenses when they can simply log in using stolen or manipulated access. This shift has made attacks faster, harder to detect, and more damaging in terms of business impact. For cybersecurity professionals, this means rethinking how security is approached. It is no longer enough to protect systems. The focus must shift to protecting identities, monitoring behavior, and reducing trust-based vulnerabilities. Organizations that understand this shift and adapt their defenses accordingly will be better prepared for the challenges ahead. Those that continue to rely on outdated models will find it increasingly difficult to keep up.
