In 2017, 62 million Brazilians suffered some type of cyber attack. Among the most common scams are the theft of personal data, such as passwords, credit card numbers or documents, in addition to the leakage of confidential information and fraud in online commerce. The information was released by a survey by Norton Symantec, an Internet security solutions company.
The Internet Security Threat Report, published annually by Norton Symantec, further confirms that these cyber attacks are on the rise and are only likely to grow. Despite the improvement of antivirus programs, the scams are also becoming more sophisticated. Therefore, I need to be very careful in your online activities. Pay attention to all links and files received, whether via chat, email or SMS. In order not to be a victim of any of these scams, check out a list of the most common crimes and see how to protect yourself from each of them.

What ransomware: five tips to protect yourself
Phishing is a technique used by cyber criminals to steal personal information and data by sending fraudulent addresses. When the scam is successful, the user accesses fake but real-looking Internet pages. Then, he inserts personal data on the website that he believes to be reliable. Phishing can occur, for example, by a fake bank email that alerts you that your account is in trouble and needs to be updated.
Never open attachments carelessly, unless you are sure of what the content is about and know who sent it. Antivirus programs – which should always be up to date – are able to detect this type of malicious activity and usually direct it automatically to the spam folder. Still, one message or another can go unnoticed and reach you, so all the necessary care.

On social media, the danger can appear in different ways. In addition to the malicious links disseminated on Facebook or Twitter, there is also the issue of privacy. Checking in, posting photos of where you are, or posting a lot of confidential information can be a gateway for personal data thieves.
To protect yourself, I never need to click or post links that look suspicious. If the page address is strange, do not access it. It is not recommended to do tests or quizzes that ask for permission to log into your Facebook account. You are literally giving access to your information and, depending on the site, even your friends too.
Avoid exposing your life in detail on social media. Leave on your friends list only those you know. If you feel more secure, keep all accounts private. You can use social networks, just avoid exposing very intimate information to anyone.
Baiting comes from the English word for bait. The scam consists of criminals leaving pen drives or other media (such as DVDs) infected with viruses in random places to attract the curious. The person accesses the device's files on their own PC and inadvertently installs a malicious application on the machine.
It is easy to protect yourself from this threat. Never use a pen drive, memory card or CDs of unknown origin. And, if you need to do it for work reasons, for example, pass the antivirus before performing any activity with the device.

This type of coup is very high this year, due to the expectation of major events, such as the World Cup and the presidential elections. Crime occurs by sending malicious addresses that offer gifts, cash prizes and even job openings. These fake promotions can be spread on any platform, from social networks to messengers like WhatsApp.
The most unsuspecting pass the blow on to their contacts, so that the current only increases. The idea of hackers in this modality would lead the user to click on malicious links and install an application that collects information such as passwords or personal data, whether on the computer or cell phone. Another possibility is to induce the victim to fill in false forms by redirecting her to the alleged promotion's website. The data is then sold on the black market to carry out different types of fraud, such as opening bank accounts.
So never click on any suspicious addresses. In this case, the best thing to do is to contact the company's SAC directly to confirm if it is running any promotions. Be wary of forms that ask for a lot of information and never give them personal passwords, be it Facebook, email or bank account.
