The National Cybersecurity Agency reports ransomware attacks around the world

The National Cybersecurity Agency's Computer Security Incident Response team said it has detected a massive ransomware attack happening around the world (in about 120 countries), with around a thousand compromised servers.

Which countries are most affected? first all France, but also Finland and Italy would register massive attacks, ditto for Canada and the United States. Despite this, it is strange that only Italy seems to have sounded the alarm, with the French media, for example, which have not reported the news at all – at least so far.

The attack would have targeted VMware ESXi servers, exploiting a vulnerability by all those who use these systems. It is recommended to carry out the updates recommended by the manufacturer.

Description

Massive exploitation of the vulnerability for the purpose of releasing ransomware has recently been detected CVE-2021–21974 treated by this CSIRT in the alert AL03/210224/CSIRT-ITA. On the related campaign, the French Computer Emergency Response Team (CERT-FR) has published a security advisory, available in the references section, which highlights the related details.

From the analyzes carried out, the campaign is also directed towards national subjects.

How it occurs

A virus ransomware takes control of a user's computer by violating cybersecurity, encrypts the data, preventing access to it and then asking for a ransom to get it back.
