The “Deepfake CEO” Scam Why Voice Cloning Is the New Business Email Compromise (BEC)

Tanya Wetson-Catt • 9 February 2026

The phone rings, and it’s your boss. The voice is unmistakable; with the same flow and tone you’ve come to expect. They’re asking for a favour: an urgent bank transfer to lock in a new vendor contract, or sensitive client information that’s strictly confidential. Everything about the call feels normal, and your trust kicks in immediately. It’s hard to say no to your boss, and so you begin to act.

What if this isn’t really your boss on the other end? What if every inflection, every word you think you recognise has been perfectly mimicked by a cybercriminal? In seconds, a routine call could turn into a costly mistake; money gone, data compromised, and consequences that ripple far beyond the office.

What was once the stuff of science fiction is now a real threat for businesses. Cybercriminals have moved beyond poorly written phishing emails to sophisticated AI voice cloning scams, signalling a new and alarming evolution in corporate fraud.

How AI Voice Cloning Scams Are Changing the Threat Landscape

We have spent years learning how to spot suspicious emails by looking for misspelled domains, odd grammar, and unsolicited attachments. Yet we haven’t trained our ears to question the voices of people we know, and that’s exactly what AI voice cloning scams exploit.

Attackers only need a few seconds of audio to replicate a person’s voice, and they can easily acquire this from press releases, news interviews, presentations, and social media posts. Once they obtain the voice samples, attackers use widely available AI tools to create models capable of saying anything they type.

The barrier to entry for these attacks is surprisingly low. AI tools have proliferated in recent years, covering applications from text and audio, to video creation and coding. A scammer doesn’t need to be a programming expert to impersonate your CEO, they only need a recording and a script.

The Evolution of Business Email Compromise

Traditionally, business email compromise (BEC) involved compromising a legitimate email account through techniques like phishing and spoofing a domain to trick employees into sending money or confidential information. BEC scams relied heavily on text-based deception, which could be easily countered using email and spam filters. While these attacks are still prevalent, they are becoming harder to pull off as email filters improve.

Voice cloning, however, lowers your guard by adding a touch of urgency and trust that emails cannot match. While you can sit back and check email headers and a sender’s IP address before responding, when your boss is on the phone sounding stressed, your immediate instinct is to help.

“Vishing” (voice phishing) uses AI voice cloning to bypass the various technical safeguards built around email and even voice-based verification systems. Attackers target the human element directly by creating high-pressure situations where the victim feels they must act fast to save the day.

Why Does It Work?

Voice cloning scams succeed because they manipulate organisational hierarchies and social norms. Most employees are conditioned to say “yes” to leadership, and few feel they can challenge a direct request from a senior executive. Attackers take advantage of this, often making calls right before weekends or holidays to increase pressure and reduce the victim’s ability to verify the request.

More importantly, the technology can convincingly replicate emotional cues such as anger, desperation, or fatigue. It is this emotional manipulation that disrupts logical thinking.

Challenges in Audio Deepfake Detection

Detecting a fake voice is far more difficult than spotting a fraudulent email. Few tools currently exist for real-time audio deepfake detection, and human ears are unreliable, as the brain often fills in gaps to make sense of what we hear.

That said, there are some common tell-tale signs, such as the voice sounding slightly robotic or having digital artifacts when saying complex words. Other subtle signs you can listen for include unnatural breathing patterns, weird background noise, or personal cues such as how a particular person greets you.

Depending on human detection is an unreliable approach, as technological improvements will eventually eliminate these detectable flaws. Instead, procedural checks should be implemented to verify authenticity.

Why Cybersecurity Awareness Training Must Evolve

Many corporate training programs remain outdated, focusing primarily on password hygiene and link checking. Modern cybersecurity awareness must also address emerging threats like AI. Employees need to understand how easily caller IDs can be spoofed and that a familiar voice is no longer a guarantee of identity.

Modern IT security training should include policies and simulations for vishing attacks to test how staff respond under pressure. These trainings should be mandatory for all employees with access to sensitive data, including finance teams, IT administrators, HR professionals, and executive assistants.

Establishing Verification Protocols

The best defence against voice cloning is a strict verification protocol. Establish a “zero trust” policy for voice-based requests involving money or data. If a request comes in by phone, it must be verified through a secondary channel. For example, if the CEO calls requesting a bank transfer, the employee should hang up and call the CEO back on their internal line or send a message via an encrypted messaging app like Teams or Slack to confirm.

Some companies are also implementing challenge-response phrases and “safe words” known only by specific personnel. If the caller cannot provide or respond to the phrase, the request is immediately declined.

The Future of Identity Verification

We are entering an era where digital identity is fluid. As AI voice cloning scams evolve, we may see a renewed emphasis on in-person verification for high-value transactions and the adoption of cryptographic signatures for voice communications.

Until technology catches up, a strong verification process is your best defence. Slow down transaction approvals, as scammers rely on speed and panic. Introducing deliberate pauses and verification steps disrupts their workflow.

Securing Your Organisation Against Synthetic Threats

The threat of deepfakes extends beyond financial loss. It can lead to reputational damage, stock price volatility, and legal liability. A recording of a CEO making offensive comments could go viral before the company can prove it is a fake.

Organisations need a crisis communication plan that specifically addresses deepfakes since voice phishing is just the beginning. As AI tools become multimodal, we will likely see real-time video deepfakes joining these voice scams, and you will need to know how to prove that a recording is false to the press and public. Waiting until an incident occurs means you will already be too late.

Does your organisation have the right protocols to stop a deepfake attack? We help businesses assess their vulnerabilities and build resilient verification processes that protect their assets without slowing down operations.

Micro-SaaS Vetting: The 5-Minute Security Check for Browser Add-ons

by Tanya Wetson-Catt • 25 May 2026

Browser add-ons have a funny reputation. They feel “small”. A quick install. A tiny productivity boost. A harmless little helper that lives in your toolbar. But in practice, a browser extension is more like a micro-SaaS vendor sitting inside your browser session. It can see what you see, interact with the pages you open, and sometimes access the same cloud apps your business runs on all day. That’s why a browser extension security check matters. Not because every extension is bad, but because it only takes one over-permissioned add-on or one bad update to turn “helpful” into exposure. The good news is you don’t need a 40-page policy to reduce the risk. A simple five-minute check can prevent most extension problems before they start. Why Browser Extensions Are a High-Leverage Risk Browser extensions sit in the most sensitive place in modern work: the browser tab where your staff live all day. That matters because extensions aren’t just “apps”. They’re granted special authorisations inside the browser. That makes them attractive targets and gives them leverage that’s disproportionate to how “small” they feel. UC Berkeley’s guidance says extensions get “special authorisations,” and the more you install, the bigger the attack surface becomes. The risk is often permission-based. OWASP calls out “permissions overreach” as a core problem. Extensions can request more access than they need, including access to “all tabs, browsing history, and even sensitive user data.” When an extension can read and modify what happens in the browser, it can potentially see data in cloud tools, capture what’s typed into forms, or alter content on a page. It’s also a “change over time” risk. A useful extension today can become a different extension tomorrow. The 5-Minute Browser Extension Security Check This browser extension security check is designed to be fast, repeatable, and realistic. It helps staff make safe decisions in minutes without turning every extension into a big IT ticket. Vet the developer like a real vendor If you wouldn’t give a random supplier access to your customer records, don’t give a random extension access to your browser. Start with the basics: Confirm the developer has a real website, support details, and a consistent name across listings Look for a track record (other products, a clear company presence, updates that look normal) Prefer official stores and trusted sources over “download this .zip” links

LinkedIn "Social Engineering": Protecting Your Staff from Fake Recruitment Scams

by Tanya Wetson-Catt • 22 May 2026

A fake recruiter message is one of the cleanest social engineering tricks around because it doesn’t look like a trick. That’s why LinkedIn recruitment scams work so well inside real businesses. They don’t arrive as malware. They arrive as a normal conversation that nudges someone toward one small action: click this link, open this file, “verify” this detail, move the chat to a different app. A few simple checks, a couple of hard-stop rules, and an easy way to report suspicious outreach can shut these scams down without slowing anyone down. LinkedIn Recruitment Scams LinkedIn recruitment scams artfully blend into normal professional behaviour. The message doesn’t look like a “cyber attack.” It looks like networking, and it borrows credibility from recognisable brands, polished profiles, and familiar hiring language. At platform scale, the volume is also hard to wrap your head around. Rest of World reports that LinkedIn said it “identified and removed 80.6 million fake accounts” at registration from July to December 2024. A LinkedIn spokesperson claimed “over 99%” of the fake accounts they remove are detected proactively before anyone reports them. Even with that level of detection, enough scam activity still leaks through to reach real employees. That’s especially true when scammers tailor their approach to what looks credible in a specific industry and location. The other reason these scams succeed is that they follow a predictable persuasion pattern: urgency, authority, and a quick push to “do the next step.” The FTC describes scammers impersonating well-known companies and then steering targets toward actions that create leverage. These actions include handing over sensitive personal information or sending money for “equipment” or other upfront costs. Once someone is rushed into treating the process as real, the scam doesn’t need to be technically sophisticated. It just needs the victim to keep moving. The Scam Pattern Most Teams Miss 1. A polished approach on LinkedIn The profile looks credible enough, the role sounds plausible, and the message is written in a professional tone. The job post itself may still be oddly generic, though. Amoria Bond notes that fake job postings often “lack details” and lean on broad language to catch as many people as possible. 2. A quick push off-platform The conversation shifts to email, WhatsApp/Telegram, or a “recruitment portal” link. That shift is important because it removes the built-in friction of LinkedIn’s environment and makes it easier to send links, files, and instructions.

3. A credibility wrapper: “assessment”, “interview pack”, or “onboarding”

Airswift flags link/attachment requests and urgency tactics as common red flags. The story is usually something like: “Download this assessment,” “Review these onboarding steps,” or “Log in here to schedule.” Tag Apps Make decisions visible and repeatable by tagging apps. Microsoft explicitly calls tagging apps as sanctioned or unsanctioned an important step, because it lets you filter, track progress, and drive consistent action over time. 4. The pivot: money, sensitive info, or account takeover Scammers impersonate well-known companies and then ask for things legitimate employers typically don’t: payment for “equipment” or early requests for personal information. Another variation is more subtle: “verification” steps that are really designed to steal identity details or compromise accounts. 5. Pressure to keep moving If someone hesitates, the scam leans on urgency: “limited slots,” “fast-track hiring,” “complete this today.” That’s why Forbes frames the key skill as slowing down and checking details, because the scam depends on momentum. Red Flags Checklist for Staff Here are the red flags to look out for. Red flags in the job posting The role is oddly vague or overly broad. Generic responsibilities, unclear reporting lines, and “we’ll share details later” language are common in fake listings. The company's presence doesn’t match the brand name. Thin company pages, inconsistent logos/branding, or a web presence that feels incomplete are worth pausing on. The process is “too easy, too fast.” If the listing implies immediate hiring with minimal steps, treat it as suspicious. Red flags in recruiter behaviour They push you off LinkedIn quickly. Moving to WhatsApp/Telegram or personal email early is a common tactic. They use a personal email address or unusual contact details. Be specifically cautious of recruiters using free webmail accounts instead of a company domain. They avoid verification. If they dodge basic questions, treat that as a signal, not a scheduling issue Hard-stop requests Any request for money or fees. Application fees, equipment purchases, “training costs”, gift cards, crypto, that’s a hard stop. Requests for sensitive personal info early. Bank details, identity documents, tax forms, or “background checks” before a real interview process is established. Requests for verification codes. If anyone asks you to read back a one-time code sent to your phone/email, assume they’re trying to take over an account. Requests for non-public company information like org charts, internal system details, client lists, invoice processes and security tools. Look out for requisitions for anything beyond what a recruiter would reasonably need. Stop Scams With Simple Defaults LinkedIn recruitment scams don’t succeed because staff are careless. They succeed because the outreach looks normal, the process feels familiar, and the next step is always framed as urgent. The fix isn’t turning everyone into an investigator. It’s setting simple defaults that make scams harder to complete: slow down before clicking, verify the recruiter and role through official channels, keep conversations on-platform until identity checks out, and treat money requests, code requests, and early personal data demands as hard stops. When those habits are standardised, the scam loses its leverage.

The "Legacy Debt" Audit: Identifying the 3 Oldest Risks in Your Server Room

by Tanya Wetson-Catt • 18 May 2026

The most dangerous thing in a server room is often the phrase, “Don’t touch that.” It’s usually said with a half-joke and a grimace. It refers to the old box that “still works”, runs something important, and has survived so many fixes and workarounds that nobody feels confident changing it anymore. That’s legacy debt. Not just “old tech”, but old tech that’s become a dependency. It’s the kind that quietly accumulates risk until it turns into downtime, security exposure, or an emergency upgrade at the worst possible time. A legacy debt audit is the fast way to bring that risk back into the light. What Legacy Debt Really Looks Like Legacy debt isn’t “old gear”. It’s old gear that has become normal. It’s the server that runs a critical app, the edge device nobody remembers buying, the workaround that turned into a dependency. Over time, that debt stacks up quietly. Infinite Lambda describes legacy debt as something that “happens even to the best systems,” “silently accruing costs and constraints,” and it can “accumulate basically unnoticed until it is too costly to ignore.” That’s why a legacy debt audit isn’t a theoretical exercise. It’s a visibility exercise to bring the oldest, highest-leverage risks back onto the list of things you actively manage. The security problem shows up when “old” becomes “unpatchable.” The UK’s NCSC guidance on obsolete products says, “Ideally, once out of date, technology should not be used,” and “the only fully effective way to mitigate this risk is to stop using the obsolete product.” If something can’t be updated, weaknesses don’t age out. They sit there, waiting for the wrong day. Legacy debt also looks like basic server hygiene slipping. NIST SP 800-123 frames secure server operations as an ongoing process: “Maintaining the secure configuration through application of appropriate patches and upgrades, security testing, monitoring of logs, and backups…” It also calls out foundational hardening steps like “Patch and upgrade the operating system” and “Remove or disable unnecessary services, applications, and network protocols.” When those basics become inconsistent, legacy debt turns into a reliability and incident-response problem, not just a security one. Finally, legacy debt often hides at the edge. If you have end-of-support internet-facing devices, you’ve got high-leverage risk in the most exposed place. The 3 Oldest Risks to Find First These three categories are where “old” most often turns into outsized risk, because they combine age with leverage: they either sit at the front door, can’t be fixed anymore, or have quietly drifted out of a safe baseline. Risk #1: End-of-support edge devices If you’re looking for high-leverage legacy debt, start at the edge. Firewalls, VPN gateways, routers, and other internet-facing devices are the front door to your environment. When they reach end-of-support (EOS), they don’t just become outdated. They become harder to defend because security fixes stop arriving. What to check in your audit List every edge device (firewall, VPN, router) and the support status for each one Confirm which ones are internet-facing and which services are exposed Identify devices that can’t run the current firmware or no longer receive updates. Risk #2: Obsolete products that can’t be fixed anymore Obsolete products are the purest form of legacy debt: things that are still operating but no longer receive security updates. That means every new vulnerability becomes permanent. In other words, there’s no clever workaround that makes an unsupported system “safe”. There are only risk reductions until you can replace it. What to check in your audit Identify anything past support: server OS versions, appliances, old hypervisors, and line-of-business apps Flag systems that require exceptions, like the ones with old protocols, weak auth, and special firewall rules Find the “business-critical but unsupported” systems. Risk #3: “It still works” servers with neglected basics This is the sneakiest risk because it looks normal. The server is supported. The hardware runs. Nobody’s complaining. But the basics have drifted: patching is inconsistent, unnecessary services are still running, and backups haven’t been proven under pressure. SP 800-123 Guide to General Server Security frames secure server operations as an ongoing discipline, including “patches and upgrades,” “monitoring of logs,” and “backups.” It also calls out core hardening steps like “Patch and upgrade the operating system” and “Remove or disable unnecessary services, applications, and network protocols.” Those are the unglamorous fundamentals that stop small problems from turning into long outages. What to check in your audit Patch reality: what’s the current patch level and how often do updates slip? Service sprawl: what’s running that doesn’t need to be running? Admin and service accounts: where are the broad permissions and shared credentials? Backup confidence: when was the last restore test and did it succeed? Change control: who can make changes, and how are they tracked? Stop Carrying Silent Risk Legacy debt doesn’t announce itself. It sits quietly in the background until the day it becomes downtime, exposure, or an emergency upgrade you didn’t plan for. A legacy debt audit gives you control back by turning “we should deal with that someday” into a shortlist you can act on. Start with the highest-leverage risks: end-of-support edge devices, obsolete products that can’t be patched, and servers where the basics have drifted. Then assign owners, set dates, and move one item at a time from “too scary to touch” to “handled”. Contact us for help running your next legacy debt audit.
