“We didn’t even know we were hacked—until customer data leaked.”
This chilling confession from a mid-sized UK retail firm could’ve been anyone. All it took was a single employee opening a WhatsApp message that contained malicious code. The result? A severe data breach, reputational damage, and months of recovery efforts.
In today’s digital-first business world, WhatsApp isn’t just a messaging app—it’s a critical communication tool. But as reliance on WhatsApp grows, so does its attractiveness to cybercriminals. The latest WhatsApp vulnerability is not a hypothetical risk—it’s a real, exploitable flaw that can lead to severe business consequences. This blog will break down what the vulnerability is, who’s affected, why it matters, how it works, and most importantly, what your organisation can do about it.
Let’s unpack what every business leader and IT professional needs to know now.
Understanding the Latest WhatsApp Vulnerability
What happened?
In March 2025, cybersecurity researchers at Check Point uncovered a critical zero-day WhatsApp vulnerability that allowed attackers to execute malicious code via specially crafted video files sent through WhatsApp. When users viewed the video, malicious scripts were silently deployed on the device, granting cybercriminals access to local storage, the camera, the microphone, and even WhatsApp chat logs.
According to Meta (WhatsApp’s parent company), over 2 billion users globally are potentially exposed to this flaw, with enterprise accounts being prime targets.
Why WhatsApp Vulnerability Is a Business Problem
The WhatsApp vulnerability isn’t just a technical glitch—it poses serious risks to your business operations, data security, compliance, and brand reputation. Here’s exactly why it should be a top priority for business leaders:
1. People Use WhatsApp for Work Every Day
- Many businesses use WhatsApp to talk to clients, send documents, or handle customer service.
- This means private business info is being shared there.
If hackers break in, they can steal sensitive data like contracts, passwords, or payment info.
2. Hackers Can Sneak In Without You Knowing
- This new issue lets hackers attack just by sending a video.
- You don’t even have to click anything—just viewing the video is enough.
That’s dangerous because it’s invisible and silent, so you might not even realise you’ve been hacked.
3. Employees Often Use Personal Phones for Work
- Many workers use their smartphones to check work messages.
- These phones might not be fully protected or up to date.
If just one phone gets infected, a hacker could get into your whole business network.
4. Hacked Accounts Can Trick Your Staff or Customers
- If someone hacks a WhatsApp account, they can send fake messages pretending to be you.
- They might ask a customer for payment or send a dangerous link to your team.
This can cause money loss or spread the attack further.
5. You Could Break the Law Without Realising
- If your company handles customer data (like names, phone numbers, or payment info), you must follow data protection laws.
- If WhatsApp is used without proper controls, you could be breaking rules like GDPR.
That can lead to fines or legal trouble for your business.
6. Customers Will Lose Trust
- If customers find out your WhatsApp was hacked, they may not trust you to protect their information again.
- They might stop doing business with you or tell others.
Even one breach can hurt your reputation badly.
7. Hackers Might Use WhatsApp to Break Into Bigger Systems
- Once hackers get into one device, they often try to reach more—like your email, files, or even bank details.
What starts as a small issue on WhatsApp could lead to a bigger cyberattack on your entire company.
8. Leaders and Executives Are Prime Targets
- Company leaders often use WhatsApp to talk to important contacts.
- Hackers know this—and they love targeting high-level people.
If the boss’s phone is hacked, it could expose critical business info.
9. WhatsApp Is Hard for Your IT Team to Watch
- Unlike email or company chat apps, WhatsApp messages can’t be easily checked or backed up by your IT team.
- That makes it tough to see if something suspicious is happening.
It’s like a dark corner of your network that no one’s watching.
10. Most Companies Don’t Take It Seriously Until It’s Too Late
- Because WhatsApp feels “safe” and easy to use, many businesses ignore the risks.
- They don’t realise how exposed they are—until something goes wrong.
Being unprepared makes you an easy target for cybercriminals.
How to Mitigate the WhatsApp Vulnerability
Here’s what cybersecurity experts at Transputec recommend doing immediately:
1. Patch and Update
Ensure all employees update to the latest WhatsApp version. Meta has released an emergency security patch, but adoption remains slow.
2. Establish Messaging Protocols
Create a corporate policy that dictates which messaging platforms are permitted for work communication, and ensure WhatsApp isn’t used without encryption and endpoint security.
3. Invest in MDM Solutions
Use Mobile Device Management (MDM) platforms to enforce controls on employee devices and remotely wipe data if a breach occurs.
4. Use Endpoint Detection and Response (EDR) Tools
EDR solutions monitor suspicious behaviours on employee devices, such as unauthorised access attempts or memory spikes.
5. Educate Employees
Run simulation training to help employees spot suspicious files and report suspicious activity on their devices.
