Picture opening WhatsApp and noticing messages sent that you never wrote. Account cloning in the app, one of the most widely used globally, has become a growing concern for millions of users. Criminals employ sophisticated techniques, such as social engineering and SIM swapping, to access others’ accounts and carry out scams. Additionally, the introduction of Meta AI to WhatsApp has brought new possibilities, like creating images and answering questions, but it also demands caution to protect personal data.
WhatsApp’s popularity, with over 2 billion global users, makes it a constant target for cybercriminals. In Brazil, where the app is nearly ubiquitous, cloning cases have surged significantly in recent years. Meta AI, launched in the country in October 2024, adds a layer of innovation but also raises privacy concerns. This text details how to identify if your account has been compromised and explores the features of the new artificial intelligence tool.
- Warning signs of cloning: Messages sent without your authorization, login notifications from unknown devices, and unsolicited verification codes.
- Using Meta AI: The tool allows creating images, answering questions, and generating quizzes, but requires care to avoid sharing sensitive data.
- Protection measures: Enabling two-step verification and monitoring connected devices are essential steps for security.
Detecting WhatsApp cloning
Unexpected notifications on your phone may be the first sign something is wrong. When a criminal attempts to register your account on another device, WhatsApp sends a message indicating your number is being used elsewhere. This alert, often accompanied by a six-digit code, signals a cloning attempt. Ignoring or sharing this code can lead to complete loss of account access.
Another common clue is sudden disconnection from the app on your phone. Since WhatsApp does not allow simultaneous use of an account on two smartphones, any login on another device logs out the original user. Changes to your profile, such as unauthorized photo or status updates, are also key indicators. Criminals often tweak these details to deceive contacts.
Messages marked as read that you haven’t opened or chats with unfamiliar contacts may suggest unauthorized access. In some cases, audio messages appear as listened to, even if you haven’t played them. Regularly checking these activities helps detect issues before they escalate.
- Login notification: Receiving an alert that your account was registered on another device.
- SMS codes: Receiving verification tokens without requesting them.
- Strange activity: Messages sent or read without your knowledge.
- Profile changes: Unauthorized alterations to photo or status.
Methods used by scammers
Cybercriminals use various techniques to clone WhatsApp accounts. Social engineering, for instance, involves manipulating victims into providing sensitive information, like verification codes. Scammers may pose as bank representatives, companies, or even friends, requesting data under convincing pretexts, such as emergencies or promotions.
The SIM swap scam is another common method. Here, the criminal contacts the phone carrier, pretending to be the account holder, and requests the number be transferred to a new SIM card. With access to the number, the intruder can receive verification codes and take over the account. This fraud relies on authentication flaws by the carrier but has become more frequent.
Malicious apps also pose a threat. Software downloaded from untrustworthy sources can capture phone data, including WhatsApp verification codes. Additionally, misuse of WhatsApp Web, when the QR code is scanned on an unknown device, allows criminals to monitor conversations in real time.
Steps to recover a cloned account
When an account is compromised, quick action is critical. The first step is to reinstall WhatsApp on your phone and log in with your original phone number. During the process, the app sends a verification code via SMS. Entering this code will automatically disconnect the intruder, as the account can only be active on one device at a time.
In cases of SIM swapping, the user must immediately contact the phone carrier to block the compromised SIM card. Requesting a new SIM with the same number and reconfiguring WhatsApp is the next step. This process may take a few hours, depending on the carrier, but is essential to regain control of the line.
If account access isn’t recovered immediately, WhatsApp support can be contacted. Sending an email to [email protected] with the subject “Cloned/stolen account” and including the phone number in international format (+55 followed by area code and number) is recommended. Support can temporarily deactivate the account, giving the user 30 days to reactivate it.
- App reinstallation: Uninstall and reinstall WhatsApp to regain access.
- Carrier contact: Block the SIM card in case of SIM swap and request a new one.
- WhatsApp support: Email details to deactivate the compromised account.
- Notify contacts: Inform friends and family about the cloning to prevent scams.
Preventing cloning
Preventing cloning requires daily vigilance. Enabling two-step verification is one of the most effective measures. This feature, available in the app’s settings, requires a six-digit PIN whenever the account is registered on a new device. Even if a criminal obtains the verification code, the PIN blocks access.
Avoiding public Wi-Fi networks also reduces risks. These often insecure connections can be exploited to capture phone data. Never sharing the SMS verification code is a fundamental rule. Scammers frequently use fake messages to trick users into sharing this code.
Monitoring devices linked to WhatsApp Web is another essential practice. By accessing the “Connected devices” section in settings, users can view all devices tied to their account and disconnect unknown ones. This check should be done regularly, especially after using WhatsApp on shared computers.
Introduction to Meta AI on WhatsApp
Meta AI, launched in Brazil in October 2024, brought a new dimension to WhatsApp. Integrated directly into the app, the tool allows tasks like answering questions, creating images, and generating quizzes. Available in 43 countries and 12 languages, the AI already has 500 million monthly active users, according to Meta.
To use Meta AI, tap the blue icon in the app’s top corner, accept the terms of use, and start a conversation. Powered by the Llama 3 model, the tool can handle a wide range of queries, from everyday questions to complex tasks like creating photo montages or translating texts.
Despite its features, Meta AI has sparked privacy debates. Data collection for AI training, especially before its Brazil launch, raised concerns among users and authorities. Meta assures that private WhatsApp conversations are not accessed by the tool, only direct interactions with the chatbot.
- Chatbot access: Tap the blue icon in WhatsApp to start a conversation.
- Available features: Image creation, question answering, and quiz generation.
- Privacy concerns: Public data may be used to train the AI.
Practical Meta AI features
Meta AI stands out for its versatility. Users can request image creation with the “imagine” command followed by a detailed description. Generated images carry a watermark indicating they were AI-created, ensuring transparency. This feature is useful for creating visual content for social media or personal projects.
Another standout is the ability to generate multiple-choice quizzes. Students can use the tool to create tests based on specific content, while groups can use it for interactive quizzes. Meta AI also offers personalized suggestions, like gardening tips based on local weather or meal planning ideas.
The tool is accessible directly in WhatsApp, requiring no additional apps. However, using it in group chats requires mentioning “@MetaAI” to activate the assistant. This integration simplifies access but demands caution to avoid sharing sensitive information during interactions.
Precautions when using Meta AI
While Meta AI is powerful, users must take precautions to protect their data. Meta clarifies that only messages sent directly to the chatbot are processed, but the use of public data for AI training has drawn criticism. In Brazil, the launch was delayed due to concerns related to the General Data Protection Law (LGPD).
To minimize risks, avoid sharing personal information, such as phone numbers or addresses, when interacting with Meta AI. Enabling two-step verification on WhatsApp also protects the account from unauthorized access, especially when using the AI on shared devices.
Users wishing to limit Meta AI use can hide the assistant’s chat, though it cannot be fully disabled. Reviewing WhatsApp’s privacy settings and Meta AI’s terms of use is recommended to understand how data is handled.
- Avoid sensitive data: Don’t share personal information with the chatbot.
- Two-step verification: Enable to secure the account during AI use.
- Hide chat: Reduce the assistant’s visibility in the app.
- Review terms: Understand Meta’s data usage policies.
Risks of cloning
WhatsApp cloning can have severe consequences. Criminals with account access can send fake messages in the user’s name, requesting money or personal information. These scams often exploit the trust of friends and family, leading to financial losses and reputational damage.
For business accounts, the impacts are even more significant. Scammers may send fraudulent links or fake promotions to clients, harming the company’s image. In some cases, criminals access conversation backups stored on Google Drive or iCloud, gaining access to old messages and media.
Protecting backups with end-to-end encryption is essential. This feature, available in WhatsApp settings, prevents intruders from accessing saved conversations, even if they obtain cloud storage credentials.
Advanced preventive measures
Beyond basic practices like two-step verification, installing a trusted antivirus on the phone adds an extra layer of protection. Programs like McAfee, recognized for security certifications, can detect malicious apps and block threats in real time. Keeping the phone’s operating system updated also reduces vulnerabilities.
Avoiding suspicious links sent via messages is another key recommendation. Many cloning scams start with phishing, where users are tricked into providing data on fake websites mimicking WhatsApp. Checking URLs before clicking and being wary of urgent messages are habits that minimize risks.
Businesses using WhatsApp Business must be especially cautious. Setting up automated responses and monitoring client interactions helps identify suspicious activity. Training teams to recognize scam attempts is an effective strategy for protecting corporate accounts.
- Trusted antivirus: Install recognized programs to detect threats.
- System updates: Keep the phone secure against vulnerabilities.
