  • December 2021’s Most Wanted Malware: Trickbot, Emotet and the Log4j plague

    Published on January 18, 2022

    Check Point Research reveals that Emotet has risen from eighth to second place in the most prevalent malwares index while Trickbot remains on top. Apache Log4j is the most exploited vulnerability.

    Dubai, UAE : Check Point Research, the Threat Intelligence arm of Check Point® Software Technologies Ltd. (NASDAQ: CHKP), a leading provider of cyber security solutions globally, has published its latest Global Threat Index for December 2021. In a month that saw the Apache Log4j vulnerability sweep the internet, researchers reported that Trickbot is still the most prevalent malware in the UAE, affecting 8% of organizations in December 2021 as compared to 7% in November 2021. The recently resurgent Emotet has swiftly risen from eighth position to second as it targets nearly 3% of the organisations in the UAE with close to 2% in November 2021. CPR also reveals that the most attacked industry continues to be Education/Research.

    This month “Apache Log4j Remote Code Execution” is the most exploited vulnerability, affecting 48.3% of organizations globally. The vulnerability was first reported on December 9th in the Apache logging package Log4j – the most popular Java logging library used in many Internet services and apps with over 400,000 downloads from its GitHub project. The vulnerability caused a new plague, impacting almost half of all companies worldwide in a very short space of time. Attackers are able to exploit vulnerable apps to execute cryptojackers and other malware on compromised servers. Until now, most of the attacks have focused on the use of cryptocurrency mining at the expense of the victims however, advanced attackers have started to act aggressively and take advantage of the breach on high-quality targets.

    “The security landscape is becoming more complex and strenuous to determine. We recently witnessed Log4j, one of the most serious vulnerabilities we have ever encountered, and due to the complexity in patching it and its easiness to exploit, it is likely to stay with us for many years to come unless companies take immediate action to prevent attacks,” said Ram Narayanan, Country Manager at Check Point Software Technologies, Middle East. “This month we have also seen the Emotet botnet move from the eighth most prevalent malware in the UAE to the second. As assumed, it did not take much time for Emotet to build a strong foundation since it reappeared in November. It is evasive and is spreading fast via phishing emails with malicious attachments or links. According to Check Point Software’s latest threat intelligence report, 84% of the malicious files in United Arab Emirates were delivered via email in the last 30 days. It is now more important than ever to have a robust email security solution in place and to ensure that users know how to identify suspicious looking messages or attachments.” 

    CPR revealed this month that Education/Research is the most attacked industry globally, followed by Government/Military and ISP/MSP. “Apache Log4j Remote Code Execution” is the most commonly exploited vulnerability, impacting 48.3% of organizations globally, followed by “Web Server Exposed Git Repository Information Disclosure” which affects 43.8% of organizations worldwide. “HTTP Headers Remote Code Execution” remains in third place in the top exploited vulnerabilities list, with a global impact of 41.5%.
