When you talk about cyber security It is always emphasized that all users, without exception, must be careful when clicking on unknown links, downloading files and even what they post on social networks. Believe “it will never happen to me” is a common error, as the credentials can be sold by hackers on the dark web either Deep Web (deep web).
It should be remembered that the Deep Web is found on the Internet and its pages can be accessed through a browser and search engine, similar to the Surface Web that everyone knows and uses. The difference is that sites like YouTube, FacebookWikipedia, Twitter, among others, are indexedthis means that they are publicly seen in the first results of the search engine. Deep web sites are not indexed.
According to the Royal Spanish Academy (RAE), the word indexing means: “Register data and information in an orderly manner, to prepare its index”. It means that they are sites that appear in Google results, for example. Although the sites found on the Surface Web are vast, they represent a small part of the Internet.
Non-indexed sites stay in a “deep” part. Many of them are not “evil” because they are sites known by the name of “intranet” and are used by companies for their employees to communicate.
However, this option of not appearing in search engines was used by hackers to sell illegal things such as: Personal data of those who have attacked with social engineering.
In addition to child pornography sites, violent videos, narcotics or forged documents, there are for sale medical records, subscription service credentials, driver’s licenses scanned, among others that according to data from Kasperski, they cost the following:
– Data of credit cardbetween US$6 and US$10.
– driving licenses scanned, between US$5 and US$25.
– passports scanned, between US$6 and US$15.
– subscription servicesbetween US$0.5 and US$8.
– selfie with documentsbetween US$40 and US$60.
– Medical historybetween US$1 and US$30.
– IDbetween US$0.5 and US$10.
The last point also includes full name, date of birth, social security number, email, mobile phone, among other data. Although the price may seem affordable, accessing the dark web to make purchases can be risky.
Part of the danger is due to the fact that the supply could be fraud, that is, the transaction is completed but the purchase is never received or something does not match. On the other hand, that the cyber police or hackers they detect it.
It should be noted that to transact on the deep web bitcoin needed (in fact they are known as the currencies of the Deep Web). Cryptocurrencies are the safest method to make purchases without being trackedThis is thanks to the fact that they are decentralized and do not go through the view of financial entities.
Another reason why it is used is thanks to the chain blocks (blockchain), since analyzing them requires a large technological investment and data collection from all its nodes.
