"According to the conclusions of the latest edition of the ESET Security Report, the biggest concern for companies in the region is the ransomware. This is the reason why the ESET laboratory analyzed the families with the greatest presence in terms of detections in Latin America in 2018, and concluded that the ransomware he is still active and reinvents himself in search of new victims"commented Jorge Zeballos, general manager of ESET Peru.
After analyzing a large number of families, the executive added, we confirm that the first place in the number of detections, even the double that follows, is WanaCryptor; especially in Venezuela, where it has a total of 2407 detections. This malicious code, the most frequently mentioned worldwide during 2017, spreads through known vulnerabilities and is still very active.
The following graph shows the relationship between families of ransomware most striking and total detections in Latin America.
"The ransomware appearing in the second and third place are Teslacryp and Crysis. The latter shows the victim through a window that his files are encrypted and which steps must be followed to restore the information. It is important to draw attention to the activity of a fourth family, who can steal certain sensitive information in addition to encrypting the files of the victim.", Remarked Zeballos.
Venezuela, Peru and Mexico are the countries with the highest number of detections in Latin America. Very often through Colombia and Brazil.
"Despite that it is the ransomware The greatest concern of users in our region is that there is still a long way to go before that concern turns to specific prevention measures. According to the results of the surveys conducted in the ESET security report to more than 2,500 companies in Latin America, only 68% of large companies backup of your information and only 56% at the smallest. Similarly, only 40% of large companies classify information, ie it makes a good backup"said Zeballos.
He added that, taking into account that Wanacryptor, the ransomware Most popular used a Windows vulnerability for which there was a patch that was released two months before the outbreak. Companies should have known how important it is to have up-to-date equipment. Of the large companies, only 43% use a solution for managing software patches and updates and only 20% of small businesses.
"These threats are there to stay and every day they try to evolve and reinvent themselves, the trends are not encouraging and the profitability of these malicious codes remains favorable for cyber criminals, and therefore it is necessary to keep information and other possessions Protecting antivirus and back-up copies, operating system and application updates, along with education are a strong barrier to stop and reduce the impact and growth of these threats.", Ready with Zeballos.
