Hacker attack? Five Signs Your PC Has Been Affected
If you don't pay attention, you can fall victim to malware or a hacker attack on the Internet. How to know you've been hacked.
If the computer suddenly takes on a life of its own, it is likely to have been the victim of a hacker attack. According to Matthias Friese, web security expert and founder of patronus.io, "Cybercriminals often target companies. But private users are also affected - and notice the attacks late or not at all". Here the expert reveals how even laypeople can recognize hacker attacks:
1. Your computer desktop takes on a life of its own
If files move and install on their own, you could harbor uninvited guests like Trojans on your system. Mostly camouflaged by inconspicuous file names, Trojans nestle in the system unnoticed. Trojans can be used for various attacks, for example for spying on sensitive data. These are then sold for a profit: Cybercriminals receive the equivalent of between 20 and 40 euros for credit card data.
2. Your searches are constantly being redirected
You haven't made a mistake and are constantly ending up on pages that you have never looked for? These are signs of a so-called "browser hijacker", malware that automatically opens certain websites. With every click and visit to the site, internet criminals make money. Since browser Trojans can also be used to spy on secret data, they should definitely be removed. This is where adware removers and browser cleaning programs are used.
3. Your computer is constantly overloaded
If your computer reacts slowly, this could be a sign that it is busy in the background. Or maybe you got into bad company unexpectedly: a botnet. This is a network of computers that were hijacked without the knowledge and consent of the owner. Computers obtained in this way can be checked and remotely controlled by cyber criminals and misused for various attacks. As a layperson, it is extremely difficult to track down bots. In the event of any suspicion, the cleanest solution is to completely rebuild your system and reinstall the operating system.
4. You see unusual warnings on the desktop
With these "scareware pop-ups", the affected user is warned of possible dangers in order to induce them to buy or install (malicious) software. In doing so, logos or error messages are often used in order to imitate the professionalism of software manufacturers. This constant exposure to fear is usually caused by so-called "drive-by downloads": Sometimes criminals manage to manipulate websites in such a way that visitors become infected with malware without being noticed when they visit the site. Regular browser updates are particularly important here in order to reduce the risk of these attacks.
5. Money will be withdrawn from your account
It is the fault of criminals who got hold of your account details. Often this happens through phishing. The term is an artificial word that is made up of the terms "Password" and "fishing ". These attacks use fake websites or messages to trick recipients into disclosing sensitive data. Raising awareness of" social engineering "is the best protection against these attacks. Be careful Opening e-mails or giving out data on the phone are also a good defense against data fishermen. Even if it looks real at first glance, would your bank really send you an e-mail or phone to reveal your TAN in an emergency? and ask for a PIN? Certainly not.
