Cybercrime & Digital Threats

Linux powers many cloud infrastructures today. However, it is not immune to threats and risks. We discuss several pressing security issues including malware and vulnerabilities that compromise Linux systems in the first half of 2021.

Our research sheds light on the tools and techniques used by TeamTNT and the potential impact of the group’s sundry malicious activities.

Ransomware-stricken organizations grapple with multilevel extortion schemes that are advancing at an alarming rate. What exactly happens in these campaigns? We scrutinize three active ransomware families associated with these schemes to find out.

Modern ransomware like Nefilim present new challenges and security concerns for enterprises across the world. How do these new families differ from traditional ransomware? And what can organizations do to mitigate risks?

These tools were intended for use in security research and other authorized purposes. However, cybercriminals have found a way to exploit them for ransomware campaigns. What are some of these tools and how exactly are they weaponized?

Many employees have set up makeshift work spaces in their homes. This could leave them more susceptible to ransomware attacks that take advantage of vulnerabilities in unsecured spaces.

Ransomware continues the trend of targeted attacks but with the added challenge of double extortion. Organizations need to be one step ahead of such coercive tactics to avoid potential disruptions, financial losses, and reputational damage.

This article aims to discuss the Linux threat landscape and examine how Linux has become an attractive target for attackers, as well as how it can be prone to a variety of threats and risks.

We discuss the behaviors and external indicators of some phishing campaigns that we observed from the latter part of December 2020 to the first weeks of January 2021.
