Ransomware can arrive through a simple file. For example a Word, Excel or PDF document. Cybercriminals are going to put this type of malware there and try to get the victim to open it to infect the computer. This is when the ransomware is actually executed and the problem of encrypting the files starts.

What they do is send an attached file, which can be one of those that we have named. are going to use some strategy to get the victim’s attention. For example, saying that it is an unpaid invoice, an important document that you have to read, some change in the employment contract…
To make this more believable they are going to impersonate identity of an organization or company. If, for example, they are going to say that it is an error that has occurred in the Facebook account, they are going to impersonate this social network. This includes the name, logo, etc. They will show a supposed file that must be downloaded and where all the information to solve the problem will be.
Opening that document is when the attack starts. The ransomware will run and start encrypting files or the system itself. You will not be able to access documents that you have saved and you may lose important information. Cybercriminals will ask for a financial ransom in exchange for you to get all the content back.
