Trending Topics Cybersecurity – March 2023

SECURITY INSIGHTS | April 03, 2023

Myra's monthly security highlights provide IT decision-makers and security professionals with the most relevant topics from the world of cybersecurity. Current trends, defense strategies and news on cyber attacks, attack campaigns and more can be found here in a clearly arranged format.

Public administration is still one of the preferred targets of cybercriminals. Most recently, the authorities of the city of Rastatt were hit by an attack and could not be reached by email or telephone as a result of this attack. In the meantime, federal states and municipalities have moved to actively "fight back”: More and more initiatives with the slogan "Prevention against cyber attacks" are being founded. In Rhineland-Palatinate, for example, there are now specialized cybercrime units, a working group of the ministry and the leading municipal associations, and a mobile response team (MIRT) for the state administration to strengthen cyber and information security.

Particularly in the healthcare sector, data requiring special protection is handled daily, and its sensitivity makes it exceedingly attractive to cybercriminals. For example, Hospital Clinic de Barcelona recently had to cancel 150 surgeries and close to 3,000 scheduled examinations due to a ransomware attack. Cybercriminals are also becoming increasingly unscrupulous in their attacks: For example, the cybergang Alphv posted nude pictures of breast cancer patients on its Darknet website. This was preceded by an attack on the Lehigh Valley Health Network (LVHN) in Pennsylvania. German institutions were also affected: Criminals used malware to capture the data of 39 patients at Essen University Medical Center and published it on the darknet.

This and other important news, developments and insights from IT security can be found in the following overview.
