If you suspect your computer has been hacked, there are a few steps you should take to protect your data and to prevent the hacker from continuing to breach your system.
First, try to identify how the hacker gained access to your system. This can be done by checking your firewall settings and by examining the system logs. If the hacker used an exploit in a software application, you should update the application to the latest version as soon as possible. Also check to see if any new accounts have been created or if any files or folders have been created or modified.
Second, change all of your passwords, especially for financial accounts. Choose strong passwords that are at least eight characters long and contain a combination of upper and lower case letters, numbers, and symbols. Additionally, enable two-factor authentication if available.
Third, scan your computer with anti-malware software. Check to make sure the software is up-to-date, and keep it regularly updated. This will detect any malware that may have been installed on your computer by the hacker.
Fourth, disconnect your computer from the internet to limit the hacker’s ability to access your system. Change the settings on your router so that it no longer allows remote access. Additionally, consider disabling your computer’s Wi-Fi and Bluetooth connections to reduce the risk of unauthorized access.
Fifth, backup your data to an external source. This can be done by copying the data from your hard drive to a USB drive or to a cloud-based storage service. This will ensure that you can retrieve your data even if your computer is compromised.
Finally, if you believe the hacker has accessed sensitive information, you should contact the relevant authorities. In addition, make sure you inform any financial institutions or companies who may have been affected by the breach.
These steps will help protect your data and minimize the damage caused by a hacker. It is important to take these steps quickly if you suspect your computer has been hacked, as the longer the hacker has access to your system, the more likely it is that they will be able to exploit your information.
