“Ongoing education of staff about cyber threats and e-mail user safety is the most efficient prevention of such cyber incidents, therefore the National Cyber Security Centre experts will deliver such a course for the National Public Health Centre staff in the nearest while,” Vice Minister of National Defence Margiris Abukevičius says.
Director of the National Cyber Security Centre Dr. Rytis Rainys stresses that the investigation has revealed loopholes in the efforts of institutions to prevent such incidents, therefore the National Cyber Security Centre has updated its recommendations for protection against such malicious codes getting into their internal networks. “From the cybersecurity point of view, e-mail filtering policy must be rigid, for example, e-mail letters with archived attachments, executable files, or documents that ask for enabling have to be blocked – only those e-mail letters that are verified for absence of malicious codes should be delivered to users,” warns R. Rainys.
This was the second sizeable surge of infected e-mail letters identified by the National Cyber Security Centre in the past quarter. The first attempt to incident of spreading the Trojan.Emotet code by e-mail letters was recorded in October 2020. Public sectors of other countries were subject to similar Emotet attacks too.
The investigation and recommendations are provided on the official National Cyber Security Centre website.
