Data stolen and then resold on the black market

There would never have been as many data leaks as in 2021, according to Damien Bancal, computer security expert from the Zataz blog.

Several causes have been mentioned.

Tenable highlights in particular the multiplication of attacks via ransomware.

These are malicious software capable of paralyzing a computer system before hackers demand a ransom, usually in Bitcoin.

In 2021, many companies have been confronted with this type of computer attack.

Result: thousands of data were stolen and then resold on the dark Web.

For example, the identity cards of 3,000 French people or the data of 39 million French people ended up for sale on a black market.

At the same time, big corporations such as oil pipeline operator Colonial Pipeline have seen their operations crippled by a ransom demand of millions of dollars.
