The increase in cyber attacks targeting messaging applications has put millions of users on alert. Digital Criminosos constantly improves its tactics to gain unauthorized access to accounts, using methods ranging from social engineering to sending malicious links. The objective is almost always the same: steal personal data, apply financial scams to the victim’s contacts or spread disinformation.
Cybersecurity reports indicate that the cloning of accounts on WhatsApp recorded a significant growth of 20% in 2025, a direct reflection of the popularity and importance of the platform in daily communication. Esse scenario reinforces the need for users to adopt a proactive stance in relation to the security of their information, understanding the risks and the tools available for protection.
The main vulnerability exploited by scammers is the six-digit verification code, sent via SMS to authenticate account access. Once in possession of this code, the attacker is able to register the victim’s number on another device, taking full control of the profile. Felizmente, there are effective methods for identifying an invasion and reversing the situation quickly.
Signs that your account has been compromised
The first indication that something is wrong is the sudden loss of access to the application. If WhatsApp asks for a new verification code without you starting the process, it’s a strong sign that someone else is trying to register your number. Além Furthermore, messages that appear as read without you having opened them indicate that a third party is monitoring your conversations. It is essential to be aware of any unusual activity, as early detection is crucial to minimizing damage.
Other warning signs include unauthorized changes to your profile, such as changing your photo or status message. Contatos who report receiving strange messages or requests for money from you are also clear evidence of account compromise. Criminals often impersonate the victim to deceive friends and family, making immediate communication about the intrusion a collective protection measure.
The most common tactics used by criminals
Social engineering continues to be the most used technique. Golpistas contact the victim through calls or messages, pretending to be from well-known companies or WhatsApp’s own technical support, and request the verification code under a false pretext.
Sending malicious links (phishing) via SMS, email or even other conversations in the app is another recurring tactic. By clicking on the link, the user may be directed to a fake page that requests the authentication code or installs spyware on the device.
Misusing WhatsApp Web also poses a significant risk. A criminal can scan your cell phone’s QR code in a moment of distraction, gaining mirrored, real-time access to all your conversations from a computer.
Spyware are spy programs that, once installed, monitor all cell phone activities, including entering passwords and accessing applications. An unexplained increase in mobile data consumption or battery discharge may be an indication of the presence of this type of malicious software.
Immediate steps to regain control
When you suspect cloning, the first action should be to try to re-register your WhatsApp account. Abra the app and enter your phone number to request a new verification code via SMS. Esse process will automatically log out the attacker who is using your account on another device.
If the criminal activated two-step verification with a PIN you don’t know, the app will require this password. Após a few wrong attempts, access will be temporarily blocked. Nesse case, you will need to wait a period of seven days to be able to recover the account without the PIN, just with the SMS code.
It is essential to notify your closest contacts, through calls or other social networks, that your account has been hacked. Alerte them to ignore any suspicious messages, especially requests for money or sharing of personal information, preventing them from becoming new victims of the scam.
Activating the main protective barrier
The most effective security measure to prevent cloning is enabling two-step verification. Esse feature adds an extra layer of protection by requiring a six-digit PIN, created by you, every time your phone number is registered on a new device. Mesmo If a criminal manages to steal the verification code sent by SMS, he will not be able to access your account without this personal password. Para configure, access “Settings” on your WhatsApp, then go to “Account” and select “Two-step confirmation”. The process is simple, fast and drastically increases the security of your profile, being recommended by all cybersecurity experts as an essential practice.
Checking active sessions and other precautions
Another important practice is to regularly monitor active sessions on WhatsApp Web or Desktop. In the “Connected devices” section within settings, you can view all computers and browsers with access to your account.
If you identify any unknown devices in the list, disconnect them immediately. Essa simple verification helps ensure no one is eavesdropping on your conversations without your consent.
Strengthening your device security
Keeping your smartphone’s operating system up to date is vital, as updates often include fixes for security flaws. Da Likewise, installing reliable antivirus software can help detect and remove spyware and other threats that could compromise not only WhatsApp, but all data stored on your cell phone.
