Year 2017 abounded in spectacular, international cyber attacks, which resulted in large losses, not only financial ones. Technological progress allows cybercriminals to access key company resources. What should we pay attention to in 2018?

In article you can read about:

  • WannaCry, Petya,
  • CIA data leak through Wikileaks,
  • MacronLeaks i Equifax,
  • Yahoo and Uber problems with security,
  • and about difficult beginnings of 2018.

In addition to the most notorious ones, the number of smaller targeted attacks has also increased. Technological progress increases the number of gates that cybercriminals can gain access to key company resources. We live in times when digital security threats become much larger than physical ones (European Cybersecurity Market). Unfortunately, forecasts for the coming years show that there will still be a race between cybercriminals and security specialists, and the first ones are still a step ahead. Fortunately, from year to year we are smarter about the experience from previous years. Let's take a look at what 2017 has brought us.


Almost everyone has heard about WannaCry, one of the loudest cyberattacks of the past year. This malicious ransomware in a very short time infected over 300,000 computers in about 100 countries, encrypting disks, blocking access to hardware and demanding a ransom. Its huge reach and spread rate was mainly due to the exploit stolen from the NSA by a group of hackers from Shadow Brokers, which allowed it to spread in search of vulnerabilities in the software of the network.


The Petya virus hit Ukraine before the world could recover after WannaCry. Seemingly, it was an ordinary ransomware (software demanding a ransom), but there are still speculations about its true character. Subsequent analyzes indicated that the attackers' goal was destruction, not ransom, and the victims never had a chance to regain their data. The main objectives of the cyberattacks were government institutions, financial organizations, energy or telecommunications companies.

Wikileaks reveals CIA files

The scandal began in March 2017, when the WikiLeaks Portal published nearly 9,000. files and documents from the CIA cyber intelligence center. The revealed files showed that the US Intelligence Agency has for a long time worked on the creation of tools that allow hacking into most of the most popular electronic devices. It is not so much the creepy that the services had the theoretical possibility of making cyberattaks and eavesdropping on every average user of electronic devices, but the mere fact of the existence of software allowing such a detailed surveillance.


The aim of the cyberattacks, just before the second round of the presidential election in France, became the candidate of the En Marche! group Emmanuel Macron. The result of the attack was the publication of nearly 9 GB of documents and internal data from the course of the campaign, including e-mails and financial settlements in public websites.


One of the largest US economic information offices fell victim to cyberattacks, which the public was informed at the end of June 2017. Hackers have access to data of 143 million Americans, including their credit card numbers, driving licenses, insurance and names, names, addresses and dates of birth. The threat was rated very high, mainly due to the possibilities related to identity theft.


The case concerning the theft of Yahoo users' data took place much earlier, but information on this subject came to light at the turn of 2016/2017.At that time, the public was informed about the leak taking place several years earlier. As a result of the attack, hackers gained access to data of up to 3 billion people. The company admitted that the theft was, among others, dates of birth, phone numbers or passwords. According to later information, among them were also payment card or bank account details.

The attackers used cookies files, thanks to which they could gain access to user accounts to impersonate them. Then they selected the users who were interested in them. In this way, the direct victims of this attack fell about 6.5 thousand people, including politicians, journalists, representatives of foreign interviews, employees of companies, banks and institutions.


Although the attack took place in 2016, the company waited a year with its disclosure. In the meantime, they managed to pay the criminals a ransom for deleting data. As a result of the attack, criminals obtained data from 57 million users (including 7 million drivers), all thanks to the theft of passwords posted in the Github company repository.

The year 2018 has already begun...

...and it started with Meltdown and Spectre, the gaps in the Intel, AMD and ARM processors. Patching these vulnerabilities is not so simple, and the greatest risk of their use in order to attack are subject to any Internet service provider.

A more spectacular threat was the attack of hackers on the Olympic Games in Pyongsang. Although the attackers failed to disrupt the course of the opening ceremony, they effectively hampered the lives of many people by hacking the servers, disabling Wi-Fi at the stadium or TVs in the press center and blocking the Olympic website, which many fans could not print tickets.

At the beginning of February, the Swiss mobile operator Swisscom announced a data leak of approximately 800,000 users. The leakage was most likely through one of the trading partners, and among the data to which the offenders gained access were the names, addresses, birthdays and telephone numbers of Swisscom customers.

An endless arms race...

All previous experiences indicate that in the coming years cybercriminals will not be more gracious. Experts of the European Cybersecurity Forum – CYBERSEC indicate the biggest challenges that await us in 2018, among them rising tension on the cyber crime front. Recent hacking trends include cyberattacks on a mass scale, gaps in devices connected to the network and the Internet of Things. It is also projected increase in the number of fake news and cases of hacking methods used by legitimate organizations.

What is essential for entrepreneurs seems above all to raise awareness that digital security issues are not just a problem for IT departments, and that real threats apply to all companies. We have good sense, reliable knowledge and a responsible approach to security.
