A spear-phishing attack can take many different disguises.

It could be a text that looks like an urgent board alert. Or a Slack message from a “colleague” requesting a wire approval. Or even a call from a family member in need of help.

In recent years, hackers have increasingly used targeted spear-phishing tactics on corporate executives, with these attacks on business leaders increasing from 43% in 2023 to 51% in 2025, while the trend continues upward.

And though many people still picture spear phishing as a standard deceptive phishing email, in 2027, the dynamic has changed. For the people who approve a transfer, access sensitive data, or speak for the company, these attacks will be coming from almost any channel.

What is spear phishing?

Spear phishing is any targeted phishing attack built on research into a specific person, delivered through whatever channel that person is most likely to trust and act on quickly.

This scam used to be associated primarily with targeted emails, but today spear phishing takes on many different forms.

Targeted spear-phishing attacks are implemented in a variety of ways, often several at once as part of a single coordinated attack, including:

  • Malicious email attachments
  • Malicious links
  • Falsified voice/video calls
  • Compromised or spoofed accounts (like Slack, Teams, or LinkedIn)
  • Other coordinated tactics, such as advanced targeted SIM swapping, help desk/support impersonation, and more

Other types of phishing, like smishing (SMS) and vishing (voice) can also be forms of spear phishing—as long as they are planned, researched, and target a specific individual or small group.

Why spear-phishing attacks are so effective

Traditional phishing scams are fairly simple. They blast a generic “your account has been suspended” message to thousands of inboxes, knowing that, while the scam won’t work on most users, it will work on some.

For spear phishing, an attacker studies a target’s job, company, vendors, and personal life, then builds a tailored message, call, or even video for that specific person.

The end result is a scam that is often convincing to the most discerning individuals, even ones well-trained in cybersecurity best practices.

How spear phishing works

A typical spear phishing attack follows a standard pattern:

  • Reconnaissance: The attacker gathers information from data broker sites, LinkedIn, company press releases, breached credential dumps, and social media. This includes any public video and audio for voice or video deepfakes.
  • Pretexting: They build a plausible story: a vendor invoice, a board request, a legal notice, an urgent favor “from” (or for) the CEO. Pretexts typically reference something real, a deal the target is actually working on, a conference they actually attended, a colleague who actually exists. This data may be private, coming from the result of previous breaches.
  • Delivery: The message or call arrives via email, text, a Slack or Teams DM, a social media message, or a live phone or video call using a cloned voice or a deepfaked face.
  • Exploitation: The target clicks a link, enters credentials, approves a payment, or stays on the call long enough to leak information or follow instructions.

Spear phishing so often works because it removes the tells that awareness training teaches people to catch. In 2027, there are no obvious typos, unfamiliar sender, or generic greetings. The attackers might sound like a trusted individual. They might look like one.

Spear phishing vs. whaling: what’s the difference?

Often used interchangeably, spear phishing and whaling attacks are similar.

A whaling attack is a spear phishing attack aimed at the highest-value targets inside an organization: CEOs, CFOs, board members, and other senior executives. The term comes from the size of the catch.

Whale phishing uses the same reconnaissance and pretexting as any spear phishing attack; it just aims higher, and the payoff is bigger. (Think wire transfers, M&A details, board-level access.)

Who is the focus of whaling attacks? Almost always the people with the authority to approve large payments, access sensitive data, or speak for the company publicly. This makes whaling cybersecurity a distinct discipline within phishing defense, one that has to account for personal exposure (home networks, family members, social media) and not just corporate email filters.

How spear phishing is changing in 2027

For 2027, five rapidly developing trends are worth following:

  • AI has improved and expedited the research phase. Attackers used to spend hours building a target profile by hand. Generative AI now does that work in minutes—and often just as well—pulling from public records, social posts, and breached data to draft a personalized pretext at scale.
  • Impersonation attacks are becoming common. In a recent Ponemon Institute survey, 42% of respondents say their companies’ executives and board members have been targeted at least once by a fake image or video. A cloned voice needs as little as three seconds of source audio to sound convincing.
  • Collaboration platforms are closing in on email as a primary attack point. As Slack, Teams, WhatsApp, and similar tools have taken over day-to-day communication, security researchers report attackers treat them as a primary means of deception, using fake connection requests, compromised accounts, and shared files to reach targets.
  • AI phishing detection can’t reliably keep up. Detection remains a reactive form of cyber defense, with the latest AI developments always remaining one step ahead.
  • The c-suite is increasingly the target. 75% of organizations now see cyberattacks targeting senior leaders’ personal digital lives every year. Attackers are increasingly realizing the executives’ accounts—both corporate and personal—are the most direct means to infiltration.

Most common spear phishing tactics in 2027

Spear phishing rarely arrives through just one channel anymore. The common entry points typically use a combination of:

  • Email phishing: Still the primary delivery method for the initial approach, especially in attacks that later move to phone or video.
  • Smishing: Text messages are particularly effective for impersonating known services from unknown users: delivery services, banks, or IT help desks.
  • Vishing and AI deepfake impersonation: Live or AI-cloned video and voice calls can impersonate anyone, even those in your closest circle of trust.
  • Business email compromise (BEC): Attackers gain access to, or spoof, a real business email account and use it to redirect payments or request sensitive data.
  • Social media and collaboration platforms: Fake LinkedIn connections, compromised Slack or Teams accounts, and DMs on WhatsApp or Telegram.

These efforts are intended to take over accounts, send fraudulent wire transfers and install malware. Note that spear phishing is also one of the most common entry points for ransomware-as-a-service (RaaS) operators.

How to protect against spear phishing in 2027

There are a number of strategies to reduce the attack surface from phishing attacks. Here’s what BlackCloak’s experts have identified will help most for 2027’s developing threats:

  • Minimize the footprint attackers can research. 

Most spear phishing starts with public information, including: home addresses, family members’ names, travel schedules, board memberships, and any recorded video or audio of the target speaking.

Removing executives and their families from data broker sites, hardening social media accounts, and blurring homes from Google Street View cuts off a large share of the reconnaissance attackers rely on to build convincing impersonations with added context.

  • Build deepfake authentication that doesn’t depend on detection.

Any request involving money, credentials, or sensitive data, whether it arrives by email, phone, video, or DM, needs a second channel to confirm it, one the attacker can’t also control.

That means reliable impersonation authentication to confirm the request is legitimate. At the very least, an agreed-upon phrase can offer some additional security.

  • Tighten credential phishing prevention. 

Phishing-resistant multifactor authentication, passkeys or hardware keys (instead of SMS codes), password managers, and monitoring for credentials that show up in breaches all reduce what an attacker can do even after a successful click.

  • Train executives specifically, and cover every channel. 

Executives face a different threat model than the rest of the company: more targeted research, higher-value approvals, and more personal exposure across email, phone, and social platforms alike. Yet only 43% of organizations currently provide personal digital asset training, and just half plan to train executives on deepfake recognition at all.

The best anti-spear phishing software for C-level executives is actually a comprehensive suite. Inbox filtering alone isn’t enough anymore. A complete executive cybersecurity service can monitor personal accounts and home networks for risks, flag exposed personal data before it can be used in a pretext, and add impersonation protection to fight back against deepfake attacks.

FAQs: What do I do if I’m the target of spear phishing?

  • Stop before acting on the request, no matter what channel it came through.
  • Authenticate the sender through a separate channel you already know is legitimate, not a phone number or link provided in the suspicious message itself. Do not use information or passwords that might be found inside a compromised account.
  • Report it to your security team immediately, even if you’re not certain it’s malicious. If you clicked a link or entered credentials, change those credentials right away and let IT know so they can check for further access. If attackers are researching your personal digital life too, your personal email, phone, and social accounts need the same scrutiny. For executives, high-access, or high-net-worth individuals, contact personal cybersecurity services.

I clicked on a spear phishing link. What should I do?

  • Disconnect the device from your internet network if you can do so safely.
  • Change any passwords you entered on the site.
  • Enable multifactor authentication if it isn’t already applied.
  • Report the incident to your cybersecurity team, if you have one. Keep the original email or message rather than deleting it. Investigators will want it.

I’m concerned I’m the target of AI impersonation. What should I do?

I got a call that sounded exactly like my boss asking for something urgent. Could that be fake?

  • Yes. Voice cloning now needs only a few seconds of audio, pulled from a public talk, podcast, or earnings call, to produce a convincing clone.
  • Treat any urgent, unusual request that arrives by phone the same way you’d treat a suspicious email: hang up and call back on a number you already have, not one given during the call.

Is whaling the same thing as CEO fraud?

  • All CEO fraud is whaling, but not all whaling is CEO fraud. Whaling describes any spear-phishing attack aimed at senior executives; CEO fraud is a specific whaling tactic where the attacker impersonates the CEO to authorize a payment or request.

How can I tell if a message or call is spear phishing?

  • Your spear-phishing red flags include: Urgency paired with an unusual request (a payment change, a request for credentials, a demand for secrecy), pressure to move off a monitored channel or skip normal authentication, and any detail, callback number, reply-to address, or meeting link that doesn’t match what you already have on file.

How BlackCloak protects executives from phishing and whaling attacks

BlackCloak’s Digital Executive Protection Platform protects the parts of an executive’s digital life that sit outside the corporate perimeter: personal email and accounts, home networks, personal devices. This full category, unified solution also includes monitoring for exposed personal data, removal of personal information on broker sites, identity theft protection, and impersonation protection to combat deepfakes. This is all supported by a dedicated Concierge Team from a U.S.-based Security Operations Center to offer guidance, and provide incident response should a threat escalate.

When a spear-phishing or whaling attempt targets an executive personally, through email, a phone call, or a deepfaked video, BlackCloak’s security team investigates and responds directly, rather than leaving it to the executive to recognize the attack on their own.
