WhatsApp Malware Campaign Uses DLL Sideloading and BYOVD to Target Business Users

A new WhatsApp malware campaign is targeting business users by using trusted WhatsApp conversations to deliver malicious files. Attackers may send files that appear to be financial reports, account statements, invoices, or payment documents, making them difficult for employees to identify as dangerous.

The campaign reportedly uses techniques such as DLL sideloading and BYOVD (Bring Your Own Vulnerable Driver) to help malware evade or weaken security protections.

Why Businesses Should Be Careful

A compromised WhatsApp account can make a malicious file appear to come from a trusted colleague, client, or business partner. Once opened, the malware may potentially compromise the device and expose business information.

How to Stay Protected

Businesses should:

• Avoid opening unexpected WhatsApp attachments.
• Verify suspicious files with the sender through another channel.
• Never approve urgent payment requests without independent verification.
• Keep Windows and security software updated.
• Review WhatsApp linked devices regularly.
• Restrict unauthorized software and remote-access tools.
• Train employees about phishing and malware risks.

The key lesson: A file isn't automatically safe just because it comes from a known WhatsApp contact.
