Common cyber threats
Some of the most common threats include:
Phishing: Fake emails, messages, or websites that try to trick people into revealing passwords or financial information.
Malware: Malicious software such as viruses, worms, spyware, and ransomware.
Ransomware: Malware that encrypts files and demands payment to restore access.
Password attacks: Attempts to guess, steal, or crack passwords.
Data breaches: Unauthorized access to confidential information.
Basic cybersecurity practices
To stay safer online:
Use strong, unique passwords for each account.
Enable multi-factor authentication (MFA) whenever possible.
Keep your operating system and apps updated.
Avoid clicking suspicious links or downloading files from unknown sources.
Install and maintain reputable antivirus or security software.
Back up important files regularly.
Use secure Wi-Fi networks and avoid entering sensitive information on public Wi-Fi unless using a trusted VPN.
