What is cybercrime?

Cybercrime describes criminal activities that are carried out using information technology. These are not only traditional fraud crimes, but also completely new forms of crime that have only become possible through digitalization.

One example of this is phishing, where attackers steal personal data such as passwords or credit card information through fake emails or websites. Other examples of cybercrime include hacker attacks, data theft, identity fraud or extortion through so-called ransomware, where data is encrypted and only released in return for a ransom payment.

Cybercrime is a global phenomenon, as digital perpetrators know no geographical boundaries. Whether private individuals, companies or governments – anyone can become the target of cyber attacks.

Why is cybercrime so dangerous?

Cybercrime is one of the biggest challenges of the modern digital world. But why is this type of crime so dangerous? Here are some reasons:

1. global reach of the perpetrators

Cyber criminals can operate from anywhere in the world and harm victims on the other side of the globe. Thanks to the anonymity of the internet, it is often difficult for the perpetrators to be tracked down by law enforcement authorities. This makes cybercrime particularly effective and dangerous.

2. growing attack surface

With increasing digitalization, the number of potential gateways for cyberattacks is also growing. Smartphones, tablets, laptops, smart household appliances or industrial control systems – all of these devices can serve as targets for attacks. The more devices are connected to each other, the larger the attack surface becomes.

3. professionalization of the perpetrators

While hobby hackers or individual perpetrators were often behind cybercrime activities in the past, the threat situation has changed considerably. Today, it is often highly professional networks and organizations that carry out cyber attacks. These groups work in a structured manner, have a high level of technical expertise and often pursue economic or political goals. Companies and international corporations in particular are now the focus of attention, as they are worthwhile targets.

4. high damage potential

Cyberattacks on large companies or critical infrastructure, such as energy suppliers or healthcare facilities, can have devastating effects. In addition to financial damage – such as blackmail or operational downtime – trust in companies and institutions can also be permanently shaken.

What can I do to protect myself?

The good news is that there are many ways to protect yourself and your data from cyber attacks. Here are some of the most important measures:

1. sensitive handling of passwords

Passwords are the first line of defense against cyber attacks. Pay attention to them:

• Use strong passwords: A combination of upper and lower case letters, numbers and special characters.
• Create unique passwords for each account so that several of your accounts are not at risk in the event of a data leak.
• Use a password manager to help you create and store secure and complex passwords.

2. activate two-factor authentication (2FA)

Do not rely solely on passwords. Two-factor authentication offers an additional layer of security. In addition to your password, you need a second factor, such as a code sent by text message or an authentication app. Even more secure are hardware tokens, such as USB security devices, which can be connected directly to your account.

3. perform regular security updates

Outdated software is one of the biggest gateways for cyber attacks. Hackers exploit security gaps in programs and operating systems that have not yet been updated. Therefore, always install the latest updates and patches, both for your operating systems and for applications such as browsers, antivirus programs and other software.

4. be careful when dealing with emails and unknown links

Be skeptical of emails from unknown senders, especially if they contain attachments or ask you to click on links. Phishing emails are one of the most common methods used to spread malware or intercept personal data.

5. create data backups

Make regular backups of your data so that you don’t lose everything in the event of an attack, for example by ransomware. It is best to back up your data to an external storage device that is not permanently connected to the internet.

6. use antivirus and firewall software

Use reliable security software to protect your system from viruses, Trojans and other malware. A firewall can also help to block unauthorized access from outside.

Conclusion: better safe than sorry

Cybercrime is a real and ever-growing threat in our digital world. However, with the right caution and the appropriate protective measures, you can significantly reduce the risk of becoming a victim of a cyberattack. The key is to use digital technologies consciously and responsibly. Always keep your devices and software up to date, protect your accounts with strong passwords and watch out for suspicious activity.
