The Rise and Fall of Dridex: What were the Most Prevalent Malwares of Last Spring

Check Point Research (CPR) reports that the Dridex trojan, which is often used in the initial stages of ransomware attacks, has now dropped from the index after being one of the most prevalent malwares in recent months

CPR latest Global Threat Index for May 2021 has revealed that Trickbot, which first entered the list in April 2019, has now taken the top spot, while the established Dridex trojan has dropped off altogether after being one of the most popular malwares in recent months amidst a global surge in ransomware. While it’s not yet known why Dridex has fallen from the list,  indicate that the Evil Corp gang, which is well known for distributing Dridex, has rebranded and shifted its approach to evade US treasury department sanctions.

Taking first place in the index is Trickbot, which is a botnet and banking Trojan that can steal financial details, account credentials, and personally identifiable information, as well as spread within a network and drop ransomware, particularly Ryuk. It is constantly being updated with new capabilities, features and distribution vectors, which enables it to be a flexible and customizable malware that can be distributed as part of multi-purpose campaigns. Trickbot gained popularity after the takedown of the , and made fresh headlines this week as the  charged a Latvian woman for her role in creating and deploying the Trickbot malware.

Since the beginning of 2021, CPR has seen a significant increase in the volume of cyberattacks towards enterprises. When comparing to May 2020 CPR has seen an increase of 70% in the number of cyberattacks in the Americas, while EMEA presents a 97% increase compared to May 2020, and APAC sees a staggering 168% year on year increase.

While there have been a lot of talks about the recent increase in ransomware attacks, the reality is that there has been a huge increase in the total number of cyberattacks in general. It’s a significant and troubling trend, and organizations need to be aware of the risks and ensure adequate solutions are in place. Attacks cannot only be blocked; they can also be prevented, including zero-day attacks and unknown malware. With the right security solutions in place, the majority of attacks, even the most advanced ones can be prevented without disrupting the normal business flow.

CPR also revealed that “Web Server Exposed Git Repository Information Disclosure” is still the most common exploited vulnerability, impacting 48% of organizations globally, followed by “HTTP Headers Remote Code Execution (CVE-2020-13756)” which impacts 47.5% of organizations worldwide. “MVPower DVR Remote Code Execution” ranks in third place in the top exploited vulnerabilities list, with a global impact of 46%.
