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

Our latest Global Threat Index for December 2021 reveals Trickbot is still the most prevalent malware, albeit at a slightly lower rate affecting 4% of organizations worldwide (5% in November). The recently resurgent Emotet has swiftly risen from seventh position to second. 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.

Log4j dominated headlines in December. It is one of the most serious vulnerabilities we have ever witnessed, 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. This month we have also seen the Emotet botnet move from the seventh most prevalent malware to the second. Just as we suspected, it has not taken long at all for Emotet to build a strong foothold since it resurfaced in November. It is evasive and is spreading fast via phishing emails with malicious attachments or links. 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 a suspicious looking message or attachment.

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%.

Top malware families

*The arrows relate to the change in rank compared to the previous month.

This month, Trickbot is the most popular malware impacting 4% of organizations worldwide, followed by Emotet and Formbook, both with a global impact of 3%.

  1. ↔ Trickbot – Trickbot is a modular Botnet and Banking Trojan constantly being updated with new capabilities, features and distribution vectors. This enables Trickbot to be a flexible and customizable malware that can be distributed as part of multi-purpose campaigns.
  2. ↑ Emotet – Emotet is an advanced, self-propagating and modular Trojan. Emotet once used as a banking Trojan but recently is used as a distributer to other malware or malicious campaigns. It uses multiple methods for maintaining persistence and evasion techniques to avoid detection. In addition, it can spread through phishing spam emails containing malicious attachments or links.
  3. ↑ Formbook – Formbook is an InfoStealer that harvests credentials from various web browsers, collects screenshots, monitors and logs keystrokes, and can download and execute files according to its C&C orders.
  4. ↔ Agent Tesla – Agent Tesla is an advanced RAT functioning as a keylogger and information stealer, which is capable of monitoring and collecting the victim’s keyboard input, system keyboard, taking screenshots, and exfiltrating credentials to a variety of software installed on a victim’s machine (including Google Chrome, Mozilla Firefox and the Microsoft Outlook email client).
  5. ↓ Glupteba – Glupteba is a backdoor which gradually matured into a botnet. By 2019 it included a C&C address update mechanism through public BitCoin lists, an integral browser stealer capability and a router exploiter.
  6. ↓ Remcos – Remcos is a RAT that first appeared in the wild in 2016. Remcos distributes itself through malicious Microsoft Office documents which are attached to SPAM emails, and is designed to bypass Microsoft Windows UAC security and execute malware with high-level privileges.
  7. ↓ XMRig – XMRig is an open-source CPU mining software used for the mining process of the Monero cryptocurrency, and first seen in-the-wild in May 2017.
  8. ↔ Ramnit  -Ramnit is a banking Trojan that steals banking credentials, FTP passwords, session cookies and personal data.
  9. ↑ Dridex – Dridex is a Banking Trojan that targets the Windows platform, observed delivered by spam campaigns and Exploit Kits, which relies on WebInjects to intercept and redirect banking credentials to an attacker-controlled server. Dridex contacts a remote server, sends information about the infected system and can also download and execute additional modules for remote control.
  10. ↑ Phorpiex – Phorpiex is a botnet (aka Trik) has been since 2010 and at its peak controlled more than a million infected hosts. Known for distributing other malware families via spam campaigns as well as fueling large-scale spam and sextortion campaigns.
