Computer attacks have seen accelerated development in recent years. And the most dangerous involves encrypting data and requesting money for access. Computer security specialists present an important report for 2019.

SonicWall published a biannual report on global computer threats. This report is based on information collected from over one million SonicWall sensors in over 200 countries.

The new data shows a growing interest in cybercriminals for ransomware-as-a-service, open-source malware packages and cryptojacking. At the same time, the encrypted threats experienced a jump of 76% compared to the first half of last year.

Moreover, traditional PDF or Office files continue to be used to launch attacks based on user confidence in these formats. In February and March 2019, SonicWall Capture Labs researchers noted that 51% and 47% of unmet threats were distributed via PDF or other files in the Office suite.

Ransomware-as-a-Service: Kits used by attackers are at their discretion

While the volume of malware globally declined by 20%, cybersecurity specialists discovered in the first half of the year a 15% evolution of the number of ransomware attacks globally. However, in some countries the evolution was 195% as well as in the United Kingdom.

Evolution based on the preferences of cybercriminals for so-called ransomware-as-a-service (RaaS) services and open-source malware packages at their discretion on the Internet, which allow them to permanently launch new types of attacks.

The IoT industry has come to the attention of cyber attackers

As companies and consumers continue to connect to the Internet a variety of devices, without taking adequate security measures, they are increasingly being used by cyber criminals for the spread of malware.

In the first half of 2019, SonicWall saw a 55% increase in IoT attacks, a number that exceeds the cumulative values ​​of the first two quarters of the previous year.

Cryptojacking attacks remain strong because the price of Bitcoin is high

The volume of cryptojacking attacks reached 52.7 million cases in the first 6 months globally, up 9% compared to the same period in 2018.

This evolution can be partly attributed to the increase in the value of bitcoin and Monero virtual currencies, with cryptojacking attacks remaining profitable for initiators. Coinhive remains the most important cryptojacking threat, despite the closure of the service in March 2019.

One reason why this IT threat is still among the top ones detected is that the compromised websites have not been cleaned since they were infected, even though the Coinhive service no longer exists and its web address has been abandoned.
