Introduction

Cyber attacks experienced during the COVID-19 pandemic process have increased not only in vectors and numbers but also in terms of their impact. The pandemic process has expanded the surface of attacks and caused an increase in the number of cyber attacks targeting organizations through homes and offices. Also, cyber threat environments are changing with the fact that attackers are coming up with new technologies and processes constantly.

For example, in 2021, when we inspect the SolarWinds attack, which made an enormous impact, it seems that the malware has adopted a way of distributing embedded in a trusted product. After the SolarWinds attack, it has been determined that 1500 small and medium-sized companies were affected, especially the U.S. and Europe.

It has been observed that the main motivation of individual threat actors who carry out European-focused attacks is to earn financial gain. Cybercriminals have made the banking/financial sector the main target. With the crisis of the COVID-19 Pandemic, targeted ransomware attacks have increased swiftly. Many organizations that could not afford service interruptions had to pay the requested ransom. Although, some ransomware groups have demanded more ransomware, threatening organizations to publish stolen data using Double Extortion methods.

Threat actors that are supported by governments usually organize longer-term operations in the interests of the state they are affiliated with. Financial interests are in the background and trying to obtain strategic intelligence about the targeted country. It all comes to this that it is significant for security teams’ operations in today’s environment, where visibility and agility are crucial more than ever to be able to monitor cyber threat actors and their ongoing activities.

Associated Malware: APT38, one of the most productive groups, uses malware families to target financial organizations.

APT38 is a threat group supported by the North Korean regime. It was observed that this threat group carried out the largest known cyber heist. Although APT38 is known as “Lazarus” by the security community, APT38’s financial motivation, unique toolkit, tactics, techniques, and procedures (TTPs) suggest that they are a different threat group from Lazarus. in addition, APT38 is also known for aggressively destroying evidence or victim networks in its operations.
