If you’re like me, you probably receive dozens of images on WhatsApp every week; memes, screenshots, family pictures. Most of us open them without a second thought. But recently, I came across a case that made me stop and rethink this habit.
In Jabalpur, Madhya Pradesh, a man lost nearly ₹2 lakh after downloading what seemed like a harmless image from WhatsApp. That image was hiding malicious code, embedded using a technique called steganography. I had heard of steganography in cybersecurity circles, but never imagined it would be used so casually on everyday platforms like WhatsApp.

A New Breed of Digital Scam
Steganography is basically the art of hiding messages or code inside other files, in this case, images. Hackers use it to embed malicious scripts into images that appear totally normal. When someone opens or downloads the image, the code can silently install malware onto their device.
This isn’t your typical phishing scam. There’s no dodgy link to click or OTP to enter. It targets our trust and our habits especially our tendency to view and download shared media without a second glance.
Why This Scare Feels Different?
What makes this kind of scam especially worrying is how quiet and undetectable it is:
Antivirus programs don’t always catch it because the image file looks normal.
You don’t have to do much to activate the malware—sometimes just previewing the image is enough.
No red flags like suspicious URLs or odd requests for login info.
Once the malware is in, it can access your personal data, banking apps, or even take remote control of your phone.
How the WhatsApp Image Scam Typically Works
Here’s a breakdown of how the scam usually plays out:
A hacker crafts an image using steganography to hide malware inside it.
They send it through WhatsApp, either directly or in a group.
The user downloads or previews the image.
Malware installs silently in the background.
The attacker gains access to sensitive data and begins draining money or stealing credentials.
In the Jabalpur case, the victim thought he was receiving a regular image from someone he knew. Within minutes of downloading it, his bank account was compromised. It all happened so fast, and that’s what really scared me.
Who's at Risk?
If you use WhatsApp regularly, you could be a target. Especially if:
You download media from unknown contacts
Your phone doesn’t have a solid security app
You’re using an older device without recent updates
You haven’t changed your default media download settings
What You Might Notice If You're Infected
Here are a few red flags I learned to look out for:
Your phone suddenly becomes slower or overheats
Battery drains unusually fast
Apps you didn’t install start showing up
Strange activity on your network or data usage
Unauthorized transactions or app logins
What I Now Do to Protect Myself (And What You Can Too)
Turn off auto-download for media on WhatsApp
Settings > Storage and Data > Media Auto-Download > Set all to “No media”
Install a trusted mobile security app
I use Malwarebytes, but others like Norton or Bitdefender are also great.
Keep your phone updated
Regular updates patch security loopholes hackers love to exploit.
Don’t open images from unknown contacts
If it feels out of place, it probably is.
Use biometric locks for banking apps
Adds an extra layer of protection even if malware tries to access them.
Warn your family and friends
I sent a quick message to my WhatsApp groups explaining this scam. The more people know, the better.
What Needs to Happen Next
This issue is bigger than just individual precautions. I believe platforms like WhatsApp should step up their security game. Better image scanning tech and alert systems could make a huge difference. Government bodies like CERT-In should also launch awareness campaigns to warn users across India.
And maybe our telecom providers could start flagging or blocking known malicious files before they reach us.
Final Thoughts
This scam made me realize that the threat landscape is changing fast. It’s no longer just about avoiding sketchy links or never sharing your OTP. Cybercriminals are getting more creative—and sneakier.
So the next time you receive an image on WhatsApp, pause for a second before you download or forward it. It might look like a funny meme or a festival greeting, but it could be a digital trap in disguise.
Stay safe out there, and share this with someone who needs to hear it!
