The ' ransomware ' has become the digital Black Plague

The ' ransomware ' has become the digital Black Plague
The virus that has left KO to Telefónica and half the planet is not an unknown in the world of computer security, nor is Telefónica the first company that falls under the attack of a ' ransomware '. In just five years, these viruses have been located in the top 3 of the worst computer threats. The apocalypse was seen coming and just happened: Someone has turned a ' ransomware ' into a ' worm ' that is propagated by the Nets only automatically.

Cybersecurity experts as respected as the Englishman Kevin Beaumont or Spanish Bernardo Quintero, creator of VirusTotal, endorse the thesis that we are before a ' worm '. In the case of Telefónica, it is confirmed that the initial infection was caused by a ' spam ' campaign, but the most worrying thing is that it was neither necessary. With this type of ' worms ', it is possible to infect thousands of computers without an employee misleading to click on an attachment in your email or plug a malicious USB into your company's internal computer.

Reality can now be more brutal. In this massive and global attack, very focused on Europe, someone would have launched ' worms ' with ' ransomware ' functions to the Internet. These functions would be: Encrypt the computers that are in their path and ask for a ransom of 300 euros for each one, in exchange for the key that decrypts them.

The hole that this worm gets into is a Windows vulnerability for which a patch exists; The affected companies did nothing
 
As for the functions of the ' worm ', these would be to walk through the networks autonomously to the search for computers that had a concrete hole, ' meddle ' by it, infect it and follow its unstoppable path. Only that one of these worms would have reached Telefónica's network, perhaps from Russia or Taiwan, where there have been even more massive infections than in Spain, would be enough to start this historic chaos.

The hole that this worm gets into is a Windows vulnerability that Microsoft reported on March 14 and for which there was a patch since then that, incomprehensibly, the affected companies had not yet installed, perhaps by having thousands of computers and non-exhaustive security policies. Or, also incomprehensiblely, they did not use antivirus, since most antivirus detected this ' ransomware ', according to data from VirusTotal.

The knowledge of this security hole we owe it to equation Group, one of the NSA's elite hacker groups, who ' enjoyed ' him for years, until another group of hackers, called Shadow brokers, stole this information and spread it to the world.
 
Like all the ' ransomware ' of today, this also collects its bailouts with the virtual currency Bitcoin. Tracing the Bitcoin addresses that the criminals have provided their victims to pay the ransom is proving that many of them are paying. As Lorenzo Martínez, technical director of Securízame explains, one of the keys to the success of ' ransomware ' is precisely that "there is a way to solve the attack based on paying a ransom that is affordable in price and that really fix it, it is not a hoax." According to Verizon, 64% of the victims end up paying.
 
70% of the attacks today
 
The possibility of an immediate economic achievement has made growing as the foam the organized ' cybercrime ' related to the ' ransomware ', creating even a business model: ' ransomware-like-service '. In this modality are offered different services to anyone who wants to start in this crime, know nothing about computers but have money to pay: there are those who will sell the virus, who will mount the collection service with Bitcoins, and even who will organize the infection.

Thus, the number of attacks of ' ransomware ' carries bending around the world since at least 2014, when it began to be a massive attack. The police can do little against these criminals, shielded in the ' cybercrime ' international, attacking normally to individuals and small businesses that have no own resources to fight against them, except the known police report.
 
There is already the ' ransomware-like-service ': You can sell the virus, mount the collection service with bitcoins and even organize the infection

With the passage of the years and the impunity of this crime, the amount of the bailouts has been increasing and its authors have dared with bigger ' fish ', like the system of transport of San Francisco and diverse hospitals. The attacks of ' ransomware ' are today 70% of all who are committed to viruses in the world, according to Verizon. We will see now, when the undertakings concerned are large and many, in an unprecedented planetary attack, if it is so easy for their authors to remain safe and sound in their hiding places, in the black caves of the underground.
