Every year there are dozens of reports of various vulnerabilities discovered and patched in the Android OS. Many of them Google detects before cybercriminals do, but some become critical threats.

Situations happen that indicate insufficient protection for mobile operating systems. And in 2021, this issue is becoming more and more of an issue.

Today, reality is largely replaced by the virtual world. We meet, communicate and play online; we have friends we have never met in real life, but we trust such people more than we trust our loved ones. We create our virtual (informational) prototype on social media pages by posting information about ourselves. By using the electronic space we think it is safe because we are only sharing information about ourselves and it doesn’t seem to apply to our ordinary lives.

Information about the person, his personal data today has become an expensive commodity that is used in different ways: someone uses this data to sell you something with the help of advertising; someone simply does not like you, and on the Internet you can be insulted, defamed, put you in a bad light, create a bad reputation and become an outcast in society; using your personal data, fraudsters, thieves can steal your money, blackmail you and force you to commit any act; and many others.

Personal data is information about an individual. This is data that allows us to recognize a person in a crowd, to identify and define him or her as a specific person. There is an enormous amount of identifying data, such as: name, first name, patronymic, date of birth, place of birth, place of residence, telephone number, email address, photo, age, etc. If we tell someone our surname, first name, patronymic, and address, we can be identified as a specific person. But if we exclude the surname or the address of residence from the list, it would be impossible to understand who the person in question is. This means that personal data is not just your first name or surname, personal data is a set of data, a combination of data that allows you to be identified.

So we can conclude that depending on how you use your personal data and how you try to prevent loss of personal data, your security depends on it. In the information age, it has become difficult to hide your data. Since it is almost impossible to hide personal data, one option remains to protect your personal data. These days there are even online courses to help you learn the basics of online security. The main thing is that this knowledge should be taught by someone knowledgeable in cybersecurity.


The development of communication technology has changed our lives. The usual processes of human relations through the Internet, take on new characteristics in the digital world. The speed at which information spreads on the Internet allows you to share your life news, pictures and communicate with many people in an instant.

The information you post can be restricted to your communication circle or made available to an unlimited number of people. However, the circulation of personal information online can lead to problems when strangers, passers-by, or even friends use the information irresponsibly and without regard for the right to privacy.

So cyberbullying and the power of technology to show negative attributes and to do so anonymously without fear of retaliation appeared. Social media became the main venue for cyberbullying. Not only can they be abusive in messages, but they can also hijack a victim’s page or create fake pages in the victim’s name where derogatory content is posted, hurtful and obscene messages are distributed.

In all forms, cyberbullying may cause significant harm to the victim, and in extreme cases may lead to the most tragic consequences.

How to protect personal data on the internet?

  1. Limit the amount of information you put online about yourself. Remove unnecessary photos, videos, addresses, phone numbers, dates of birth, relatives, and other personal information.
  2. Don’t send videos or photos to people you have met online and don’t know in real life. If you send personal information or confidential information to anyone, make sure the recipient is who he or she says he or she is.
  1. If someone asks for your personal information, like where you live, or your school or class number, or other personal information online, talk to a parent or trusted adult.
  2. Only use complex passwords, different ones for different accounts and services.
  3. Have two email addresses – a private one for correspondence (private and obscure, which you never publish in public sources), and a public one for public activities (forums, chats, etc.).

How do I protect my gadgets from malware?

  1. Install special email filters and anti-virus software on your gadgets. These can prevent both direct attacks from intruders and attacks using malicious applications.
  2. only use licensed software. Pirate copies of software are most often infected by viruses.
  3. use reputable sites.
  4. Systematically check your home computers for viruses.
  5. Back up important data.
  6. Periodically change your passwords for email, social networks, forums, etc.
  7. Consider Android penetration testing services (more details below)

What are Android Penetration Testing services and what are they for?

By ordering Android penetration testing of your app, you can identify security flaws that could lead to a data breach. Based on past information, you already know that a data breach can have serious consequences, both for an individual and a company. An important consideration when identifying vulnerabilities would be the company. After all, depending on the abilities and skills of the company doing the vulnerability testing, you will get different results.

The first time I ordered such a service I ran into some shoddy vendors that wouldn’t find any vulnerabilities afterward. I know from my school computer science course that no security system is perfect. So not having vulnerabilities on my android device made me suspicious. Then I found a second company that was doing android application penetration testing and found 8 vulnerabilities on my website. Subsequently, hacken.io specialists fixed all the invulnerabilities and solved my problems, for which I thank them.

To summarize

The development of information technology has changed the model of collecting, accumulating, using, and transmitting data, greatly simplifying our lives and making them more mobile. However, behind the convenience, simplicity, speed, and ease of use of information technology lies the other side of the coin. So, by following some elementary rules of conduct on the Internet you can protect your personal data and prevent cybercriminals from damaging your reputation or stealing your money.

Remember that technology to protect personal data is evolving, and fraudulent schemes are being developed to circumvent existing data protection schemes. Protect your data!
