What is the first thing to do if your WhatsApp, Instagram or home banking account is hacked

The key is not only to prevent, but act fast: The first minutes can define whether the incident remains a scare or becomes a major problem.

The first thing is stop the damage.

If you detect that your account has been hacked or see suspicious activity:

• Disconnect the Internet device (WiFi and mobile data).

• If you still have access, log out of all devices from account settings.

• If you have already lost access (your password was changed or 2FA was activated): immediately start the official account recovery process (“Forgot your password?” or support). Avoid trying to enter repeatedly, as you may block it.

• In parallel, secure the associated email, because it will be key to recovering it.

• Don’t delete anything yet: emails, messages or notifications can serve as evidence. This step seeks to prevent the attacker from continuing to operate with your account or stealing more information.

Once contained accessyou have to secure the account:

• Change your password from a secure device (ideally another computer).

• Use a unique and robust key (mixture of letters, numbers and symbols).

• Activate double factor authentication (2FA).

• Close open sessions and revoke access from connected apps.

If you cannot enter, start the registration process immediately. recovery official platform (WhatsApp, Instagram, bank, etc.).

One of the most common mistakes is reusing passwords. If one was hacked, the others are at risk.

• Change the passwords on all accounts where you use the same password.

• Check recent activity: sent messages, email or phone changes, suspicious movements.

• Check access from unknown locations or devices.

Key: email is the center of everything. If someone accesses your email, they can reset the rest of your accounts. Secure it first.

The problem may not just be the account, but the equipment.

• Run a full analysis security (antivirus or trusted tool).

• Delete applications or extensions that you do not recognize.

• Update the operating system and all the apps.

This reduces the risk of the attacker re-entering.

At this stage, the focus is on preventing the damage from spreading:

• Let your contacts know: You could receive fake messages asking for money.

• Reports the incident on the affected platform.

• If there are bank accounts or wallets involved, contact immediately to the bank to block operations.

The sooner you act, the easier it is to stop a scam.

Beyond the urgency, there are habits that greatly reduce the risk of hacking:

• Activate two-factor authentication on all possible accounts.

• Use unique and long passwords (do not repeat them between services).

• Do not click on suspicious links or share verification codes.

• Keep devices and applications up to date.

• Have a security solution on your computer (antivirus, there are several good and free ones).

Cybersecurity specialists agree on something: attacks are usually automated and opportunistic. They do not target a particular person, but rather those who have weak setups or oversights.

Therefore, having a clear plan of action for the first minutes not only helps you regain control, but can prevent loss of money, identity theft, or access to sensitive information.

“An account hack works like a process: it has stages. Acting quickly is key, because it can come to nothing or escalate to the loss of sensitive data and money,” explains Mario Micucci, Computer Security researcher at ESET Latin America.

The company points out that, in most cases, initial access occurs without the victim noticing: it may be due to credentials leaked in other breaches, phishing emails that deceive the user, or malware installed on the device.

“Many times the attacker already has access before the person realizes it. Therefore, every minute counts to cut that control window,” they add.

They also warn that one of the most critical points is usually email. “The email is the gateway to the rest of the accounts. If an attacker controls it, they can reset passwords and take control againl even after the victim has regained access,” says Micucci.

In terms of user behavior, the main problem remains password repetition and the lack of two-step verification. “Double factor can completely block many access attempts, even if the password has already been compromised”, stand out from ESET.

Finally, they emphasize that the emotional reaction also plays a key role. “Faced with a hack, the first enemies are panic and anxiety. Having an action plan allows you to make better decisions and reduce the impact of the incident,” concludes Micucci.
