Problems with the computer that may indicate a cyber attack

How to know if you've been cyber-attacked? Surely, after this question, you might think, what a silly question, detecting a cyber attack is very easy and obvious. However, as cybersecurity specialists, we can tell you that this is not always the case. It all depends on your technical knowledge and the type of cyber attack.

For example, ransomware attacks are easier to detect since they block access to our own information. However, phishing attacks are usually much more subtle, and sometimes it takes days to notice abnormal behaviors indicating that we've been victims of this type of attack.

Nonetheless, to make it easy, there are several types of computer problems that could indicate we have been cyber-attacked.

Some computer problems that indicate we have been cyber-attacked

Slow or unusual performance

Do you feel that your computer is running slower than usual? Before getting alarmed, first make sure all your updates are up to date. If they are, the next step is to check for the presence of malware in your software. If you lack technical knowledge, it is best to inform your company's IT department so they can perform the necessary checks, such as ensuring that it is only your computer and not the entire team's.

Spontaneous appearance of pop-ups and ads

If pop-ups and ads start appearing spontaneously on your computer, this is a sign that something is not right and could indicate malware in your system.

Automatic and unauthorized changes in system settings

If you notice changes in the system configuration without your authorization, such as the deactivation of antivirus software or modifications to critical settings, it could be indicative of a cyber attack.

Log in alerts

If you have 2FA (two-factor authentication) enabled and you receive a notification alerting you of a login attempt, it means someone has obtained your password, making you a victim of a cyber attack. If you don't have 2FA enabled, the system won't be able to alert you. Instead, you may directly notice suspicious changes or activities on your hacked account that you didn't initiate.

Missing files or programs

The unauthorized deletion or modification of important files could indicate the presence of malware or an attacker who has compromised your system.

Unauthorized use of resources

If you notice an unusually high usage of your computer resources, such as CPU or memory, it could be due to the execution of malicious software.

If you notice any of these anomalies in your computer's behavior, it's important to take immediate action to investigate and resolve the issue.

To do this, we recommend running antivirus scans, resetting passwords, and monitoring network activity.
