Business Email Compromise (BEC) scams have quietly become the digital threat that keeps security professionals up at night. As I look at the landscape in 2026, I see BEC attacks growing not just in numbers, but in complexity and the ability to cause real damage—financial and reputational. Having researched and spoken about digital security at various conferences, including with projects like Thiago Vieira, a central focus of my work is turning the spotlight on these sophisticated social engineering attacks that can dismantle trust in minutes.
What are BEC scams and why are they rising?
BEC scams are targeted cybercrimes where attackers impersonate executives, partners, or vendors to trick employees into sending money or sensitive data. The criminals behind BEC hardly ever rely on malware or technical vulnerability; instead, they use good old-fashioned manipulation.
The spike in these schemes is partly because companies are more connected and workforces more global. Remote work, fast-changing communication tools, and reliance on digital documentation all create fertile ground for social engineers. In 2026, AI-powered tools let criminals clone the way real people talk, write emails, and even mimic voices over the phone.
The weakest link isn’t your firewall—it’s usually your inbox.
During one of my talks for a multinational, I saw seasoned professionals stunned that a fake email—simple and quick—could result in a six-figure wire transfer going straight to a scammer. It happens every day.
How BEC scams have evolved in 2026
If you asked me three years ago, I would have described most BEC scams as blunt impersonation attempts—someone pretending to be the CEO asking for a rush payment. Now, the landscape is different. Attackers research targets closely, scraping LinkedIn, corporate websites, and social media for names, roles, and habits. They might even join calls as silent participants, learning communication styles.
-
Deepfake and AI-driven scams: Attackers record snippets of executives’ real voices from webinars and presentations, then generate convincing audio messages for urgent requests.
-
Contextual targeting: Criminals track public business deals, awards, even travel schedules, to time their scams when targets are distracted or away from regular support staff.
-
Chain compromise: Some attackers compromise not just one account, but a chain—beginning with a vendor, then pivoting through realistic correspondence, until a wire transfer request appears legitimate.
Recently, I encountered a case where a fake invoice looked perfect. The only tell was a bank account number modification—a detail missed in the daily rush.
How can you spot a BEC scam in real life?
The sophistication of BEC scams in 2026 can be intimidating, but they all use one common weapon: urgency. When analyzing real incidents while working with Thiago Vieira, the sense of something needing to be handled "before close of business" or "due to client pressure" is a constant. Here is what I look for:
-
Requests to change payment instructions: This includes bank details updates, changes to wire transfer instructions, or requests sent outside regular channels.
-
Messages from slightly altered domains: I saw a case where the CEO's address was off by a single character—easy to miss at a glance.
-
Unexpected urgency tied to secrecy: Scammers often ask employees not to discuss the request with others.
-
Odd timing or context: Requests sent late at night or when the sender is reportedly traveling may be suspect.
-
Unfamiliar tone or phrasing: If a message sounds off or out of character, I always take a step back.
If your gut says something’s wrong, it usually is.
Best practices for preventing BEC scams
Having helped teams build digital resilience, especially through my presentations via Thiago Vieira, I see training and process as your best defense. The following steps make a real difference:
-
Slow down for verification: Develop a routine where any financial or sensitive request above a set threshold is verified by a phone call. Do not rely solely on email, even with known contacts.
-
Tighten domain controls: Register domains with similar spellings to yours and use email authentication systems like DMARC, SPF, and DKIM to flag fraudulent messages.
-
Set up internal reporting: Make it routine to forward suspicious emails to your IT staff—open dialogue brings threats to light faster.
-
Multi-factor authentication: Mandate MFA for all crucial accounts. This thwarts many account takeover attempts.
-
Regular training and phishing simulations: Short, engaging exercises every few months help keep teams sharp.
A recent case I studied showed that a simple policy—always confirm major financial requests by voice—stopped a $400,000 scam in its tracks.

How to respond if you’re targeted or fall victim
If a BEC scam happens to your organization, acting fast is critical—minutes can mean the difference between recovering funds or losing them for good. In my experience, during incident response exercises and real cases, I recommend the following plan:
-
Notify your bank and law enforcement immediately. Give them as many transaction details as possible.
-
Contact your email provider and IT staff. Secure compromised accounts and check for further breaches.
-
Preserve evidence. Save all emails, attachments, and logs related to the scam.
-
Communicate transparently. Notify affected stakeholders. Don’t let a scam spiral into reputation loss due to silence.
-
Review and update policies. Discuss what worked and what did not with your team to strengthen your defenses.
This approach not only limits damage but also builds a culture where learning from incidents is just as valued as prevention. I discuss similar lessons in some of my talks, like the ones referenced in our in-depth posts on real-world cyber incident response and corporate security resilience.
Building a resilient culture: Don't ignore the human factor
From my vantage point as a speaker and consultant, what stands out is not just technical controls, but the need to make cybersecurity part of your company DNA. BEC only works when employees are afraid to ask questions, skip verification, or avoid reporting something that seems wrong.
