Human-Directed Threats: The New Frontline in Cybersecurity

A constantly shifting threat landscape has given rise to a new cyberattack vector, driven by two powerful forces: the rapid migration of data to the cloud and the fundamental change in how employees access and interact with that data. Today’s workforce expects the freedom to work and access information from any device—especially mobile devices, which have become integral to their professional and personal lives.

Cybercriminals have wasted no time adapting their tactics to match these developments. Instead of using traditional malware or software exploits, they are increasingly deploying sophisticated social engineering campaigns that target human vulnerabilities. Their objective is to steal legitimate user credentials—the keys to critical infrastructure and sensitive data. In many cases, credential theft marks the first step in what is known as the "modern kill chain".

Today’s enterprise IT teams must strike a delicate balance between competing priorities. Employees expect seamless access to work, create, and collaborate from anywhere. At the same time, threat actors continuously evolve their tactics, techniques, and procedures (TTPs), increasingly targeting humans as they adapt to the shifting dynamics of how and where work gets done.

The Human Factor: The Weakest Link

At the heart of this evolving threat landscape lies the human factor. While humans have long been recognized as the weakest link in any security strategy, this vulnerability has become even more critical with the rise of social engineering attacks. These human-targeted threats exploit fundamental human instincts—such as trust, curiosity, and urgency—to manipulate individuals into disclosing sensitive information, sharing credentials, granting device access, or otherwise compromising their digital security.

Historically, human-directed attacks have achieved success through conventional email phishing campaigns. However, these tactics have evolved with the rapid advancement of AI and increasingly sophisticated tools. Broad "spray and pray" phishing efforts have been replaced by highly targeted campaigns. Crude attacks marked by typographical errors and homoglyphs have been replaced by AI-generated fakes indistinguishable from legitimate communications. Isolated incidents have morphed into coordinated, omnichannel attacks, leveraging SMS (smishing), voice calls (vishing), and sophisticated phishing websites designed to deceive even the most vigilant users.

Amid these evolving tactics, mobile devices have emerged as the primary delivery vehicle for social engineering attacks. Targeting mobile users has become more common and dangerous, as mobile platforms offer attackers immediate, pervasive, and deeply personal channels to exploit human behavior.

To be clear, attackers aren’t targeting the device itself—they’re targeting the user, exploiting natural human tendencies to deceive them into surrendering corporate credentials or falling for another well-crafted scam. Mobile devices create the ideal environment for these tactics: they’re always on, widely used, and closely connected to users’ personal and professional lives. Small screens, fast-paced interactions, and urgent requests—especially from perceived authority figures—make it easier to mislead users. For example, you may have encountered the “CEO Apple Gift Card Scam”, a textbook case of simple yet highly effective social engineering. In this scheme, scammers impersonate senior executives and send urgent text messages to employees, pressuring them to purchase gift cards under the guise of a business need.

In short, humans have become the new attack surface, where a single misstep can trigger costly consequences. According to IBM’s 2024 Cost of a Data Breach Report, the average breach now costs $4.88 million—up 10% from the previous year and the highest on record.

As risk continues to grow, organizations that lack visibility into the mobile devices accessing their corporate services leave a critical gap in their overall security posture. Where visibility ends, vulnerability begins—particularly for SOC and CISO teams. A strategic, holistic approach to security must address the human factor and the pivotal role of mobile, making comprehensive mobile security essential to any effective defense strategy.

Evolving Threats Call for Evolving Defenses

Traditional cybersecurity strategies rely on complex, outdated methods centered on perimeter defenses, network controls, and securing legacy endpoints like Windows and macOS.  These traditional approaches are necessary but not sufficient.  They were never designed to defend against the advanced tactics, techniques, and procedures (TTPs) that define today’s cyberattacks, particularly those targeting the human element on modern mobile platforms such as iOS and Android..

Defending against these emerging threats requires a fundamentally new approach—one that offers protection across all channels, harnesses AI to outpace AI-based threats, and allows employees to be human without letting inevitable mistakes jeopardize the organization.  A critical component of this strategy is a robust Social Engineering Protection (SEP) solution that integrates technologies and methodologies specifically designed to detect, prevent, and respond to attacks that exploit human behavior.

But that’s only part of the equation. To complete the solution, organizations need robust Mobile Endpoint Detection and Response (EDR) to address a significant blind spot left by traditional EDR tools— visibility into mobile threats.  It gives security teams the ability to collect vital threat intelligence and telemetry, including mobile web history, messaging activity, and call records, all while respecting user privacy. This data can be correlated with signals from across the IT environment to strengthen threat detection, enhance response capabilities, and support comprehensive investigations, regardless of where the attack originated.

Better Together

Here’s a practical example of how SEP and Mobile EDR work together to detect and remediate a coordinated social engineering attack (e.g., SMS Phishing):

First, suspicious messaging activity is flagged when multiple employees receive the same SMS within a short time frame. It is often sent from a spoofed number that appears similar to internal IT contacts. The Mobile EDR system observes unusual inbound messaging volume from suspicious numbers, similar URLs shared across multiple devices, and a pattern of clicks on the link from multiple users. It flags the message pattern and correlates it with known phishing domains or previously reported threats. Messaging metadata indicates the message was delivered, and one or more users clicked the link. Web telemetry confirms users were redirected to a fake login page resembling the corporate SSO portal.

In response, the Mobile EDR system quarantines the malicious link, alerts the SOC, and isolates affected devices or initiates credential resets if login information was compromised. It also compiles a detailed timeline of messaging activity from unknown senders, web interactions, and device behavior to support investigation. This level of visibility enables security teams to swiftly assess the scope of the attack, isolate impacted accounts, and contain the threat by blocking the malicious URLs across the entire device fleet, including desktops and laptops.

While SEP and Mobile EDR tackle distinct facets of mobile security, together they create a robust, integrated defense against today’s human-centric threats. SEP is designed to prevent user-targeted attacks, while Mobile EDR provides the visibility and response capabilities necessary to contain and remediate threats that slip past initial layers of protection.

Framing the Complete Strategy

The human factor remains the weakest link in cybersecurity, and threat actors increasingly exploit this weakness through sophisticated social engineering attacks. Mobile devices have become the primary attack surface for these campaigns, offering direct, personal channels—like SMS, voice, and messaging apps—that are ideal for manipulating users and bypassing traditional security defenses.

Effectively addressing this challenge requires a tailored mobile security solution that integrates AI-powered SEP with Mobile EDR. By combining these two powerful tools, Lookout empowers security teams with real-time visibility and actionable threat intelligence across mobile endpoints, enabling faster detection, deeper investigation, and more effective response. Unlike many providers that focus primarily on traditional endpoints such as email and desktops, Lookout stands apart in delivering comprehensive Human Factor Defense designed explicitly for mobile.
