Ransomware - what is it?

Intruders are capable of stealing our cash by using more sophisticated methods as technology improves. We frequently receive messages sent to our mail or mobile device that contain images or other programs that may "interest us", but they are actually malware that can take over our mobile device or PC.

For example, you could place an advert on an ads platform about selling some product. A few hours later you get an SMS with an offer to exchange the product you are selling for another along with a link to photos of this product. If you browse this link on an Android device, you download an application that transfers all your money to accounts belonging to the intruder.

Another technique used to attack is to send out mail messages with link text and hyperlinks, which prompt users to click the link. You may receive a job offer from an attacker, and must fill out the form through this link. Your device, or computer will then be infected by a trojan, or a "keylogger" that downloads data from your drive and stores keystrokes. The attacker will then make use of these files to target your system. The attacker will be able to analyse the data and identify your passwords. This is a way to steal your personal information or cash.

What exactly is ransomware?

Ransomware, which is based upon the human mind, is a completely new way to make cash for hackers. When you click on a link your device will be blocked and you see the message as follows: "You need to transfer 100dollars to gain access back to the device and prevent loss of data. "

Most of the time, the program code alters autorun files or the registry when you open these hyperlinks. The user then sees this message. If you do make a transfer of money, it will not alter anything, and you won’t have access to your device.

Ransomware also can cause serious harm to your computer. Be aware, that this type of malware doesn't create backups. Therefore, your information will be lost forever and nobody will be able to retrieve it remotely.

Therefore, it is essential to utilize anti-virus or special programs to restore the system. In any case, don't give money to a thief!

How to Protect

The first step is to keep the database of antivirus up-to-date. Most cases of infection are protected by antivirus software.

Then, you should regularly backup your information. Make use of a removable external hard drive, or cloud services for this. It is easy to restore your data in the event that you lose it on your device.

Be alert, and that's the most important thing. The research shows that malware can cause harm to a laptop or device in the majority of instances when it opens attachments to the letter, for example, an attached image, in your mailbox. Do not open attachments to messages from unknown senders. To safeguard yourself against such messages, use temporary mailboxes. It will conceal your identity online and block any messages that are suspicious. According to studies, temporary mailboxes are least susceptible to attack of this type as their time of use is limited.

Summary

Never open email from unknown people and never open attachments.

If your device is blocked, never send money to a thief, as your device isn't unlocked. Use antivirus software or scripts to fix the issue.

You can safeguard yourself from harmful attachments with disposable mailing.
