WhatsApp Takeover: A Business Risk

WhatsApp takeover attacks are a significant and growing threat to businesses in Southern Africa. Unauthorized access to a WhatsApp account can lead to severe data breaches, financial loss, and reputational damage. This type of account compromise often serves as a gateway for broader cyberattacks, making proactive defence essential for maintaining operational integrity and client trust. Understanding the mechanisms of a WhatsApp takeover is the first step toward robust protection and compliance with data protection laws like POPIA and the Zim Cyber Act.

How a WhatsApp Takeover Occurs

Cybercriminals employ several sophisticated methods to execute a WhatsApp takeover. These techniques primarily exploit human trust and technical vulnerabilities rather than breaking WhatsApp’s end-to-end encryption. Attackers aim to gain control of your account to impersonate you, scam your contacts, or steal sensitive information. Awareness of these methods is critical for both individuals and businesses in South Africa and Zimbabwe, where mobile communication is integral to daily operations. The financial and reputational stakes are high, especially when business communications are involved in a WhatsApp security breach.

• Social Engineering: This is the most common method. An attacker, often posing as a friend or an official from a known company, tricks you into sharing your 6-digit WhatsApp verification code. They might claim it was sent to you by mistake.
• SIM Swap Fraud: A more advanced technique where criminals convince your mobile service provider to transfer your phone number to a SIM card they control. Once successful, they receive all your calls and SMS messages, including the WhatsApp verification code, locking you out entirely.
• QR Code Phishing (Quishing): Attackers trick users into scanning a malicious QR code, often sent via email or another messaging platform. This can link your WhatsApp account to their device via WhatsApp Web, giving them full access to your chats.
• Malware and Spyware: Malicious software installed on your device can record your keystrokes or grant attackers remote access, allowing them to steal verification codes and other sensitive data directly.

Steps to Prevent and Recover from a Takeover

1. Activate Two-Step Verification: This is the single most effective preventive measure. Go to WhatsApp Settings > Account > Two-Step Verification and set a 6-digit PIN. This PIN will be required when registering your phone number with WhatsApp again, preventing a takeover even if an attacker has your SMS code.
2. Never Share Verification Codes: Your 6-digit SMS registration code is a key to your account. WhatsApp will never legitimately ask you for this code. Be suspicious of any message, no matter how convincing, that requests this information. According to the UK’s Action Fraud police unit, this is a primary vector for account compromise.
3. Recover Your Account Immediately: If you suspect a takeover, sign back into WhatsApp with your phone number and enter the 6-digit code you receive via SMS. This automatically logs out anyone else using your account. If the attacker enabled a two-step verification PIN, you must wait seven days to recover your account without the PIN.
