Hello my friend here I will leave a list of the worst
Undoubtedly he was the protagonist during 2017, and will continue to be in 2018. What is this attack? It is a malicious software that infects our computer and blocks the device, encrypting all files and stored data. Once executed, the virus shows us a pop-up window in which it requests a payment for the rescue of the information. MIT cites several key examples that have taken place in the last 12 months executed by a ransomware: the attack on the National Health Service of Great Britain, the rail network in San Francisco and companies like FedEx.
However, one of the most alarming and sounded cases has been WannaCry last year. An "unprecedented" attack, carried out last Friday, May 12, 2017, which managed to infect network equipment and 230,000 computers in more than 150 countries. The objective was to encrypt the computer files to request a ransom in bitcoins.
One of the focus of action for the attackers in 2018 will be cloud computing companies, since they control large volumes of data. Google, Amazon or IBM have already hired specialized teams in digital security to avoid possible risks.
The confidential information of large companies is a big target for cyber attackers and they will remain in their sights in 2018. One of the best-known attacks during 2017 was to Equifax, the credit reporting agency, which caused the theft of phone numbers. social security and large amount of personal data of the American population.
From ElevenPaths, Telefónica's cybersecurity unit, reports are made dedicated to analyzing information leaks. For the preparation of each CyberSecurity Shot, a team of analysts makes use of monitoring tools that use current information, both in open source and in other web sites, in addition to the application of analytical methodologies for the anticipation of possible threats. If you are interested, here is the link to the publications.
Attacks against infrastructures
These types of attacks, considered "cyber-physical", are also very damaging, and constitute a great threat to large companies. The attackers act against transport systems, electrical constructions, physical networks ... with the aim of leaving them in a state of vulnerability.
Recently, in BlogThinkBig.com, we analyzed an attack of this type through 'Triton', a malware designed to attack industries and infrastructures. The Mandiant threat research team of the computer security company FireEye revealed the existence of this malware, ensuring that its creators point to the Triconex Safety Instrumented System controllers, sold by Schneider Electric. The objective? The research indicates that cybercriminals used this malware to take control of a workstation that runs Windows and works with a security system owned by Schneider Electric.
In this regard, MIT points out that the biggest threat is not the theft of cryptocurrencies, but the theft of the computer's processing power. What is the reason? Currently, mining requires a large computer capacity, this has motivated cybercriminals and has endangered the computers that perform this type of work.
One of the most recent related cases is Starbucks. The Wi-Fi network of a Starbucks in Buenos Aires was infecting the devices that were connected to perform mining through the injection of a malicious code. All the computers that connected to the network gave part of their computing capacity without knowing it.
Cyber attacks in election processes
Attacks in voting processes are other risks that must be taken in 2018. Last year, the US He formally accused Russia of having carried out cyber attacks to interfere in the presidential elections. Now, expert teams work to reduce attack vulnerability, but there are still many potential targets for cybercriminals. In this sense, Europe has created a specialized unit to fight against fake news from Russia.
