Why identity is the new internal highway for cyberattacks
Organizations spend tens to hundreds of thousands fortifying their perimeters, but the biggest threats often originate from within. This article explores how saved passwords and autonomous AI agents can create hidden pathways for cybercriminals, bypassing traditional defenses and highlighting the need for a unified approach to mapping user access.
The perimeter is an illusion
Modern businesses rely on a complex web of identities that spans directory services, cloud services, and both human and machine accounts. Each identity holds specific permissions, creating pathways that cross traditional system boundaries. When a cybercriminal compromises a credential, they don’t just steal a password; they inherit every privilege associated with that identity.
This is why modern cyberattacks seldom depend on sophisticated malware. Instead, they exploit these chains of access. A saved password on a retail laptop might lead to a forgotten, overprivileged Active Directory group. That group membership could then unlock a cloud environment, which in turn holds the keys to administrative policies. By linking these seemingly distinct and unmonitored permissions, cybercriminals can walk from a low-level foothold straight to an organization’s most critical assets.
Alarmingly, identity weaknesses were a factor in nearly 90% of investigated breaches. Cybercriminals are taking the path of least resistance: they simply log in.
The unseen workforce: AI and nonhuman identities
The integration of artificial intelligence (AI) into enterprise infrastructure is rapidly evolving the threat landscape. Nonhuman identities, such as service accounts, API keys, and autonomous AI agents, are multiplying at an exponential rate. These entities often possess far more privileges than any human employee, creating significant security vulnerabilities.
Unfortunately, the theft of nonhuman credentials is a surging trend in cybercriminal networks, with 6.2 million credentials or authentication cookies tied to AI tools.
Consider this common scenario:
- The vulnerability: A development team configures a software bridge, enabling their AI tools to interact with various enterprise systems.
- Privilege inheritance: The AI agent automatically inherits the high-level permissions granted to that bridge.
- Exploitation: If there is a flaw in the open-source software, a cybercriminal can hijack the AI agent’s identity, gaining immediate, unimpeded access to production databases and cloud resources.
These high-value, nonhuman credentials are now being traded by the millions on underground marketplaces, posing a critical risk to organizations.
Why traditional gatekeepers fail
Despite rising security budgets, identity-based attacks are on the rise. The IBM 2026 X-Force Threat Intelligence Index reports that compromising valid accounts caused 32% of initial security breaches, establishing it as the second most common entry point for attackers.
The problem stems from the outdated design of traditional identity tools. They were built for an older era of compartmentalized security:
- User management tools: While effective at managing user life cycles and granting access, these tools are blind to real-time threats such as cybercriminals moving laterally within a network.
- Secure password vaults: Although great for securing high-level credentials, these systems can’t detect when lower-tier access is chained together to bypass the vault completely.
These tools operate in silos, unable to map the complex, hybrid relationships between endpoints, directories, and cloud workloads. For example, a user management tool might flag a role provisioned for a temporary cloud migration as compliant. However, when viewed within the broader network context, this same role could function as a massive backdoor, leaving the system vulnerable.
Illuminating the blind spots
The good news is that a vast majority of modern breaches are preventable, relying on exposure rather than advanced attacker sophistication. Palo Alto’s 2025 findings revealed that over 90% of breaches were materially enabled by preventable gaps, specifically limited visibility, inconsistently applied controls, and excessive identity trust. These conditions delayed detection and created easy paths for lateral movement once cybercriminals gained access. Organizations often had the necessary budget and tools but lacked the holistic visibility to see how individual identity risks combined to form a complete attack path.
To stop modern adversaries, security programs must evolve beyond a simple gatekeeper mentality. The industry needs to adopt a continuous, visual mapping approach that tracks identities, access policies, and how everything connects in the real world. Until security teams can visualize and sever the chains linking low-level access to critical assets, identity will remain the most efficient highway for cyberattacks.

A single overlooked access key can compromise an entire digital infrastructure. In this article, we break down the growing threat of nonhuman identities, particularly AI integrations, the blind spots of legacy access management solutions, and why mapping the interconnected web of internal permissions is crucial for modern cybersecurity.
Traditional security tools often treat identity management as a simple gatekeeping function, leaving internal networks vulnerable to cybercriminals who exploit credentials. In this article, we’ll examine why cybercriminals often exploit linked permissions between company systems and why having complete visibility is the only way to effectively block their access.
Keeping an entire fleet of corporate computers running efficiently requires balancing performance with environmental responsibility. A look into your device’s settings can reveal several simple ways to reduce power consumption.
Many business leaders overlook the hidden expenses stemming from idle office hardware and poorly calibrated monitors. Implementing foundational power management habits helps protect your bottom line while minimizing your company’s carbon footprint.
Operating multiple workstations throughout the day heavily inflates commercial utility expenses. Simple, strategic modifications to standard desktop configurations can significantly reduce unnecessary electricity usage across your entire office.
Flexibility is a necessity in the era of remote work. That’s why Voice over Internet Protocol (VoIP) has become the linchpin that connects teams across homes, offices, and client sites. By consolidating calling, video meetings, messaging, and collaboration into one powerful platform, VoIP empowers remote teams to work smarter, not harder.
Remote work offers incredible freedom, but it can also lead to communication breakdowns. Without a central office, teams can feel disconnected, leading to missed calls, disorganized messages, and difficulty collaborating on projects. Voice over Internet Protocol (VoIP) is helping remote teams solve many of these obstacles. Here’s how.
Productivity problems are not always caused by a lack of effort. In many cases, teams are already working hard, but their time is consumed by one too many meetings, scattered communication, constant interruptions, or unclear handoffs between departments. Microsoft Viva Insights helps bring those patterns into view so organizations can make better decisions about how employees work.
