I often come across such a notion as phishing and I know that it is something related to network security, but I don't quite understand it. Is there anyone who can explain to me what it is and how to protect yourself from hackers. Thank you.
Phishing in different words is a cybercrime in which a hacker accuses a 'bait' by contacting via e-mail, phone or SMS via a person pretending to be a legal institution or company. Its purpose is to lure people into sharing sensitive information such as personal details, banking and credit card details and passwords. Typical hacker tricks are great deals / promotions that attract attention. For example, many say you won an iPhone, lottery, or other cool prize. Just don't click on any suspicious emails.
The next hacker method is hyperlinks, or questionable links, which may not be what you think. The link may be completely different than it seems, for example, a popular website with spelling errors.
And remember about email attachments - if you see an attachment in an email that you didn't expect or it doesn't make sense, don't open it! They often contain elements such as malware or other viruses.
Unusual Sender - Whether it looks like it's coming from someone you don't know or someone you know, if something seems unusual, unexpected, out of character or just plain suspicious, don't click on it!
The classic phishing fraud attempt begins with an email from a bank, email service provider, or other known entity. These messages usually require a click on the link to check your personal data. Failure to confirm such information leads to suspension or deletion of the account. To be true, phishing messages contain logos and images related to the activity the criminal is impersonating.
Instead of moving to a bank or other activity that we expect to see after the email, the link leads to the fraudster's website. Everything that will be entered there will be sent to the creator, together with the login and password to the trusted site. Once an account has been accessed, the attacker may use it in different ways, depending on the account type. In the case of an e-banking account, the swindler can purchase what he wants and make a transfer from our account: the email address can be used to log in to the forums, view email correspondence, send spam to other users.
Phishing is a scam used by online criminals to obtain valuable information, such as logins and passwords oraz credit card numbers.
The name evokes sound associations with fishing. Criminals, like anglers, use a properly prepared "lure". In this role they usually use fake e-mails and text messages. More and more often scammers act also through communicators and community portals.
In order to inspire the trust of the victim, phishers impersonate commonly recognized companies and institutions - banks, offices, auction portals, courier and telecommunication companies. With the help of fake messages they try to persuade the victim to click on the link in the message. It usually leads to a website created by fraudsters. It is deceptively similar to the authentic website of the company or institution from which the message allegedly comes - but in fact, it is a trap set for careless internet users.
The fraudsters use the fake website to obtain the data that the victim himself makes available to them, they are convinced that they are logging into the authentic transactional service of their bank. It is also common practice to send out fake e-mails, the content of which encourages Internet users to download a harmful file, which is included in the attachment.
Phishing is a devious method of Internet fraud, through which a criminal impersonates an institution or person. The aim of this activity is to scam personal data, such as bank account and credit card numbers, log-in passwords and other confidential information. Phishing is also called password harvesting fishing, the purpose of which is to steal credit card numbers through various techniques.
