Along with search facilities and online businesses, the internet has also brought this great concern to its users.

Therefore, it is necessary to be very careful when clicking on any file attached to the email or even on a website pop-up, especially on unknown pages, also regarded as unreliable.

What are cyber crimes?

Cybercrimes or cybercrimes (in English, cybercrimes) are any and all illegal activities carried out on the internet , through electronic devices such as computers and cell phones.

The first registration of cybercrime nomenclature occurred in the late 1990s, during a meeting of leaders of the G-8, the group of eight richest countries in the world.

Practices range from the spread of viruses through links sent by e-mail to invasions of operating systems of companies or even private ones.

With this, offenders can steal confidential information and data , being able to apply scams such as fraudulent misrepresentation, for example.

Therefore, cybercrime involves, on the one hand, one or more criminals and, on the other, one or more victims.

With the evolution of devices in recent decades, the way in which crimes are committed has also evolved.

That is, anyone is liable to be attacked.

Is there any law in Brazil against cybercrime?

Since 2012, Brazil has legislation focused on cybercrime.

Nicknamed the Carolina Dieckmann Law – an actress who had 36 intimate photos leaked on the internet -, Law No. 12,737/2012 was added to the Penal Code and started to typify specifically virtual crimes.

Despite the great repercussion due to the case of the actress, the country’s financial system already required this type of legislation because of the high number of scams and password thefts via the internet.

With the rules, criminals who invade computer devices, such as computers, notebooks, cell phones, tablets and others, supply data breach programs and, thus, disclose, trade or transmit this information, should be penalized .

The sanctions for those who illegally obtain information apply both to those who commit the crime online (connected to the internet) or offline.

Penalties range from three months to up to two years in prison , in addition to fines.

On the other hand, Law No. 12,735/2012 , that is, a little earlier than what we saw above, focuses on conducts through electronic and/or digital systems, that is, practiced against computerized systems.

And this led the state to implement specialized police stations .

Finally, the so-called Marco Civil da Internet , 2014 ( Law No. 12.965/2014 ), stipulates and regulates Internet users’ rights and duties, with the intention of protecting users’ personal information and private data.

This implies legal action against online crimes and also in relation to the possible removal of offensive or criminal content from the network.

What are the motivations behind cybercrime?

What are the motivations behind cybercrime?

The quest for notoriety (ego, after all) and personal revenge are two of the reasons criminals access computers, devices and, consequently, victims’ data.

There are also causes arising from fanaticism, especially through political or religious aspects.

However, the main cause is usually financial .

In most crimes, whether committed out of ego, revenge, or fanaticism, extortion is the number one motive for criminals.

Because they obtained data and information that is often considered confidential, they demand a so-called “ransom”, a payment for returning what was stolen.

In fact, one of the most common formats of cybercrime is ransomware, a kind of virus that hijacks information, which we’ll talk about later.

Most common types of cybercrime

Most common types of cybercrime

There are at least three categories of cybercrime.

First, there are attacks that directly use computers (both the criminal and the victim, which can be exemplified in hacker actions).

Then there are those who seek access to other computers or devices by illegally obtaining a particular network.

Finally, there are crimes in which the computer does not perform the main function, but it is essential to store, for example, confidential documents obtained from illegal access.
