In the year 2022 and as is reflected in the article “Industrial Security 2022 in numbers”, cyberattacks in all industrial sectors have increased by around 30 % in the third quarter of 2022 and it is estimated that the number of organizations or industrial manufacturers victims of a cyberattack was around 40% in the last year. Especially in the industrial sector, the number of attacks has grown exponentially due to the massive introduction of IoT devices (it is expected to go from 13.5 to 21.5 million connected devices in three years) or more specifically about IIoT devices, which have been the main gateway for attacks as manufacturers have prioritized features and mass-production of devices over the security. In addition, this is compounded by planned obsolescence planned (increasingly present in this type of devices), increased interoperability and connectivity and the appearance of new types of malware and exploits which are much more effective.

Grandoreiro, also known as Delephant, is a banking trojan from South America, which has spread its operations to other regions, especially Europe, including Spain and Portugal.

Cyberattacks using ransomware are one of the main threats for companies all over the world and Spain is the tenth most affected country. That is why, in this article, as a continuation of the previous one entitled: ‘Ransomware: preventative measures (I)’, will cover in detail new recommendations to prevent them.

Various studies with threat analysis or malware distribution campaigns affecting Spain and identified through incident management undertaken by INCIBE-CERT. The aim is to increase knowledge of the more technical details and characteristics of the threats so that organisations can implement appropriate detection and protection measures.
