CEOs now rank phishing ahead of all other cyberattack concerns, with 73% stating that they were (or know someone who was) directly affected in the last year. Spear phishing is a targeted form of phishing where attackers tailor messages to specific individuals or roles using personal, organizational, or contextual information. This added precision significantly increases the likelihood of success.

While spear phishing has been around for a while, modern attacks now combine traditional targeting methods with AI-generated content, allowing attackers to create highly convincing messages at scale. Easy-to-spot emails with poor grammar are becoming fewer and farther between. Today’s attacks are heavily tailored, context-aware, deeply embedded in communications and workflows, and are often indistinguishable from legitimate business communications. 

The result is a class of attacks that can bypass both technical controls and human intuition, making spear phishing one of the most effective and persistent threats organizations face today.

What are the Most Common Spear Phishing Techniques?

Most modern spear phishing attacks fall into a few familiar categories, often used in combination: 

• Credential harvesting 
• Malicious links and attachments
• Business communication compromise

These are not new techniques, but they have evolved significantly. Attackers have refined them to better align with real business workflows, evade detection, and increase success rates, making them far more effective than in the past.

How Has Credential Harvesting Changed?

Credential harvesting is not new, but it has become significantly more advanced and harder to detect. Attackers now impersonate trusted business systems and workflows that users rely on every day, prompting routine actions such as password resets, document access, or security alerts. These messages direct users to highly convincing login pages that are often indistinguishable from legitimate ones. Modern campaigns increasingly target not just usernames and passwords, but active session tokens, allowing attackers to take over authenticated sessions and bypass multi-factor authentication.

In more advanced attacks, adversary-in-the-middle (AiTM) techniques proxy the authentication process in real time, capturing credentials and session cookies as the user logs in. This allows attackers to hijack sessions immediately, often without triggering traditional security alerts or requiring further interaction.

What’s New with Malicious Links and Attachments?

Attackers know that most people will think twice before clicking an unknown link or opening a suspicious attachment, and they’ve pivoted accordingly. Threat actors now craft links that appear legitimate while concealing their true destination, often using compromised websites, trusted platforms, or layered redirection to bypass detection. These links are tied to realistic business activities such as file sharing, approvals, or account notifications, making them more likely to be trusted and acted on.

Attachments have shifted away from malware-infected documents to user-driven actions and workflows. While attackers will still attach PDFs, spreadsheets, and compressed files to emails, they are increasingly designed to appear relevant to the recipient’s role or current work. Instead of carrying a malicious payload directly in the attachment, they’ll often guide users through specific steps, such as enabling content or following embedded links, to trigger compromise. This approach increases success rates while reducing reliance on easily detectable malware.

What’s Changed with Business Communication Compromise?

Business communication compromise is an evolution of Business Email Compromise (BEC), where threat actors impersonate executives, vendors, or internal stakeholders to request payments, modify banking details, or obtain sensitive information. These requests are often embedded in real business processes such as invoicing, payroll, or vendor management, making them difficult to distinguish from legitimate communication. 

Increasingly, attackers go beyond email, communicating instead through text messages, workplace collaboration platforms, and embedded workflows. This shift allows attackers to engage targets across multiple channels. Additionally, these types of attacks do not rely on malicious links or attachments. By leveraging trusted communication channels and relying on heavily social engineering, they frequently evade technical controls and can bypass user awareness training focused on well-known phishing indicators.

In more advanced scenarios, attackers use techniques such as thread hijacking, where they compromise a legitimate account and insert themselves into ongoing conversations. By leveraging real message history, established relationships, and accurate context, they significantly increase credibility and reduce the likelihood of detection. This allows them to manipulate transactions or extract sensitive data with minimal friction, which often leads to financial loss, data exposure, and broader organizational compromise.

How Does AI Factor Into Spear Phishing?

AI enables attackers to produce highly convincing, context-aware phishing content with minimal effort. Messages can be tailored to specific individuals, roles, and business activities, while accurately mimicking tone, language, and communication patterns. This precision removes many of the traditional indicators users rely on to identify phishing and increases the likelihood of user interaction by eliminating many of the cues users once relied on. If you’re used to looking for unexpected requests, unusual tone or urgency, and subtle inconsistencies in links, domains, or sender context, you won’t typically find them once AI is involved.

AI also allows attackers to scale targeted campaigns, dynamically adapt content, and test variations to improve success rates. It supports more advanced techniques such as interactive phishing pages and real-time engagement, while helping evade traditional detection methods. 

Attackers are also extending campaigns beyond email, combining it with SMS (smishing), voice calls (vishing), and collaboration tools to reinforce legitimacy. Techniques such as QR code phishing (quishing) further bypass traditional defenses by shifting user interaction to mobile devices. The result is a more efficient and effective attack model that combines precision with scale.

Who Is Commonly Targeted by Spear Phishing?

While traditional phishing casts a wide net, hoping to bait an unsuspecting user, spear phishing tends to be more tactical. It targets individuals with access, authority, or influence over business processes. Common targets include:

• Executives and senior leadership who can authorize payments or access sensitive data.
• Finance and accounting teams responsible for invoices, payroll, and wire transfers.
• IT and help desk personnel with access to systems, credentials, and account recovery processes.
• HR teams that manage employee data and onboarding workflows.
• Procurement and vendor management roles involved in third-party payments and communications.

However, anyone can become a target. Spear phishing attacks also go after individual contributors who have access to internal systems that serve as entry points for lateral movement. In many cases, these users are selected based on publicly available information about their role, projects, or relationships.

The common thread is access. Whether the goal is financial fraud, credential theft, or broader compromise, attackers who use spear phishing techniques focus on individuals whose actions can move the attack forward quickly, with minimal resistance.

Why Spear Phishing Attacks Succeed and How to Break the Attack Chain

Spear phishing requires targets to follow a sequence of actions. By designing attacks that blend into normal business activity, threat actors convince their targets to click, respond, and divulge information. Understanding where and how these attacks succeed is key to stopping them.

Targeting and Context Building

Attackers identify individuals based on their role, assumed access, and business function. They build context using publicly available information, data obtained through prior breaches, and in some cases, existing email access. The data they gather allows them to align attacks with real workflows such as financial approvals, vendor communications, or internal requests. It also allows them to engage in social engineering, known as pretexting, by crafting believable scenarios and requests that match real business activity and reduce the likelihood of suspicion.

Message Alignment and Delivery

Instead of generic lures, attackers craft messages that fit naturally into day-to-day operations. This may include impersonating known contacts, inserting into existing threads, or timing messages around real business events. Delivery is no longer limited to email and may include SMS, voice, or collaboration platforms to reinforce legitimacy.

User Action and Trust Exploitation

The attack succeeds when a user takes an action that feels routine, such as logging into a system, opening a document, or approving a request, but instead grants access or triggers a malicious outcome. Because these actions align with normal workflows, they often bypass both technical controls and user suspicion. Small signals such as an unexpected request, a subtle change in tone, or a break from standard process are often the only indicators something is wrong, and they are easy to miss without clear validation steps in place.

Access, Persistence, and Expansion

Once access is obtained, attackers typically move quickly to establish persistence and expand their reach. This may include accessing email, initiating internal phishing, escalating privileges, or manipulating financial transactions. In many cases, the initial compromise is just the starting point for broader activity.
