During the first nine months of this year 495 million ransomware attacks have been registered, which represents an increase of 148 % worldwide, compared to 2020, as reported in its report by the company SonicWall.

According to the information provided by the cybersecurity expert company, 2021 has become the most expensive and dangerous year for global organizations due to the figures they have had to pay to protect the data and information of their companies.

In addition, SonicWall predicted that in the last quarter of the year attacks could increase to 714 million. The figures provided by company, highlight that in the third quarter of the year there were “a total of 190.4 million worldwide”, to become one of the most negative in the history of the company.

When comparing with 2020, it is observed that for the first 3 quarter of last year a total of 195.7 million ransomware attacks were added. Another data reported is the number of attempts to hijack the data obtained by clients during the third quarter, equivalent to 1,748, which translates into 9.7 cyberattack attempts per client in each working day.

Attacks on the rise

On the other hand, the company indicated that its technology called RTDMI, from January to September, “has discovered 307,516 new malware variants.” In addition, this technology recognized an increase by 33 % of malware that was directed to the global IoT, mainly in the United States and Europe.

The same happens with cryptojacking, where an increase of 21 % is registered worldwide, but in the European continent it is more significant, obtaining a “massive growth of 461 %”.

For the president and CEO of SonicWall, Bill Conner, “ransomware is immersed in an almost unimaginable upward trend, representing a significant risk to companies, service providers, governments and citizens”.

Microsoft reinforced the standard Windows antivirus, Microsoft Defender, with new functions that seek to prevent ‘cryptojacking’ cyberattacks, through the use of Intel’s Threat Detection Technology (TDT) automatic threat detection technology.

Cryptojacking is a type of malware that uses a part of the computing power of infected computers to mine cryptocurrencies, such as bitcoin or ethereum. This type of attack increased 43 % in the fourth quarter of 2020 compared to the previous period, according to data from Avira Protection Labs.

To protect users from this type of threat, Microsoft and Intel reached an agreement to implement the threat detection technology of this second company in the processor to the antivirus.

Threat detection and protection

The integration of Intel’s Threat Detection Technology (TDT) in Microsoft Defender allows additional detection and protection functions against ‘cryptojacking’, through the use of machine learning technologies, as the company reported in a statement.

TDT performs hardware-based low-level telemetry from the CPU’s performance monitoring unit (PMU), an element that is dedicated to collecting low-level information on performance and microarchitecture.

This system is capable of detecting the footprint left by cryptocurrency mining malware in the execution of code in real time, such as the repeated execution of mathematical calculations, “with minimal indirect expense,” according to the US company.

The new mechanism works even when obfuscation techniques occur or when malware lurks within virtualized guests, “without the need for intrusive techniques such as code injection or performing complex hypervisor introspection.”
