This way, you can enjoy WhatsApp safely and securely, minimizing any risk.
Why and how is a WhatsApp account stolen?
WhatsApp account theft is a threat that has grown in popularity, primarily due to the large amount of personal data, contacts, and confidential conversations that criminals can exploit. But how do they do it?
- Impersonation through social engineering: Scammers obtain your phone number from leaked databases or even from social media. Once they have it, they try to register your account on another device so the system can send the verification code to your phone. They then impersonate you and, using deceptive methods, ask you for these codes under seemingly plausible pretexts.
- Physical theft of the mobile phone and SIM: If you lose your phone and don't have a screen lock or advanced security measures, an attacker can access your messages, chats, and even log into your account on another device.
- Open sessions on WhatsApp Web/Desktop: Using physical access or spyware, someone can log into WhatsApp Web using your phone and have unlimited access to your chats without you even realizing it.
- Privacy vulnerabilities and malicious links: Strange messages, suspicious files, and fraudulent links may contain malware or attempt to steal sensitive information.
Main techniques used by cybercriminals
Criminals have perfected several methods to hijack WhatsApp accounts. Among the most common are:
- Fake verification code requests: They pose as technical support, friends, or institutions and request the six-digit PIN that is sent to your device.
- Phishing and malicious links: They send messages or files that redirect to fraudulent pages to steal personal data or install malware.
- Contact impersonation: They access an acquaintance's account and, from there, request sensitive information or money from their contacts.
- Access via WhatsApp Web: They leave sessions open on public or unsupervised computers to access conversations and data.
Privacy and security settings: first barriers
WhatsApp offers several privacy settings that you should know and use to protect your account:
- Profile picture, status and last connection: Define that only your contacts can see your photo, status or when you were online. Enter Settings> Privacy and choose the appropriate visibility (“My contacts” or “Nobody”).
- Locking the app and device: Secure your phone with a PIN, pattern, fingerprint, or facial recognition. Also, enable WhatsApp fingerprint lock (on supported devices).
- Hide personal information: Limit the visibility of your personal information, description, and status updates to make it harder for scammers.
These measures, although basic, make it difficult for strangers to access and reduce the possibility of data collection for fraud attempts.
How to activate and configure two-step verification correctly
Two-step verification is undoubtedly the most effective tool for protecting your account. It ensures that even if an attacker obtains your verification code via SMS, they can't access it without the additional PIN that only you know.
- Open WhatsApp and go to Settings > Account > Two-Step Verification.
- Select “Activate” and enter a six-digit PIN code that only you know.
- Associate a secure email address (ideally different from the one you use for social networks), as it will help you recover your PIN if you forget it.
- Don't share this PIN with anyone and avoid letters or numbers that are easy to guess (such as birthdays).
This way, if someone tries to register your account, they will need both codes, which drastically raises the level of security.
Management and control of connected devices
One of the most common access routes for account theft is WhatsApp Web or DesktopAnyone who scans your QR code or has physical access to your phone can maintain an open session on their device.
- Accede to Settings > Paired Devices and frequently check the list of computers and tablets connected to your account.
- If you detect any suspicious or unrecognized devices, log out of your mobile device immediately.
- Avoid logging into public or other people's computers and always remember to log out when you're finished.
Also, whenever you leave a shared computer, check the active sessions and, if possible, activates blocking systems on the computer or mobile (automatic screen closing, password, etc.).
The importance of keeping WhatsApp and your device updated
Updates to WhatsApp and your device's operating system not only bring new features, but also fix security vulnerabilities that can be exploited by attackers. Keeping the app and your phone up to date is essential to stay protected against new threats.
- Activate the Automatic Updates in your app store (Play Store or App Store).
- Regularly check that your WhatsApp is running the latest version.
- Do not install apps from unofficial sources or modified versions of WhatsApp, as they may contain malware.
How to protect your account from social engineering and impersonation threats
WhatsApp scams often start with messages from legitimate contacts, businesses, or organizations. Scammers can pose as friends, family, banks, or even WhatsApp support to gain access to your account or financial information.
- Never share your verification code nor the two-step verification PIN with anyone, even if they claim to be from official support or a family member.
- Distrust requests for money or sensitive information via WhatsApp, even if they appear to come from people you know.
- Always verify the identity of the contact if you have any doubts, do not open suspicious links.
Advanced tips to strengthen the security of your WhatsApp account
- Biometric app lock: Use features like fingerprint, Face ID, or facial recognition to access WhatsApp from your mobile. More and more devices support this feature, adding an extra layer of security.
- Strong voicemail password: Some attacks involve accessing your voicemail to obtain the verification code if you don't answer the call. Change your voicemail password to a strong, hard-to-guess password.
- Disable display of notifications on the lock screen: This way, you can prevent curious people or attackers with physical access from seeing verification codes or sensitive messages without unlocking your phone.
- Periodically review the permissions of installed apps and delete those you don't recognize or no longer use.
- Make encrypted backups of your chats in Google Drive or iCloud, so you can recover your conversations only if an incident occurs.
What to do if you've been a victim of WhatsApp account theft
No one is 100% immune to a potential attack, but if you discover your account has been accessed, follow these quick steps:
- Try recovering your account: Install WhatsApp on your phone and follow the verification procedure. If the attacker still has access, you'll receive a notification.
- Contact support: Write to support@whatsapp.com requesting deactivation of your account. Include your number in international format.
- Contact your operator: Request a SIM lock and ask for a duplicate if necessary.
- Warn your contacts: Inform them about the theft so they can be alert to any suspicious messages or requests for money they may receive from your number.
Remember that if your account is suspended, you have a period of time to recover it, along with your messages and files, if you had backup enabled.
