September 2024’s Most Wanted Malware: Notable AI-Driven Techniques and Persistent RansomHub Threats
Check Point’s latest threat index emphasizes the shift towards AI-driven malware tactics in the current cyber landscape
Check Point’s Global Threat Index for September 2024 revealed its Global Threat Index for September 2024. The report highlights an interesting trend in the cybersecurity landscape, particularly the emergence of artificial intelligence (AI)-driven malware, alongside the ongoing dominance of ransomware threats.
This month, researchers discovered that threat actors likely used AI to develop a script that delivers AsyncRAT malware, which has now ranked 10th on the most prevalent malware list. The method involved HTML smuggling, where a password-protected ZIP file containing malicious VBScript code was sent to initiate an infection chain on the victim’s device. The well-structured and commented code suggested AI involvement. Once fully executed, AsyncRAT is installed, enabling the attacker to record keystrokes, remotely control the infected device, and deploy additional malware. This discovery highlights a growing trend of cybercriminals with limited technical skills using AI to create malware more easily.
The fact that threat actors have started utilizing generative AI as part of their attack infrastructure highlights the continuous evolution of cyber-attack tactics. Cybercriminals are increasingly leveraging available technologies to enhance their operations, making it essential for organizations to implement proactive security strategies, including advanced prevention methods and comprehensive training for their teams.
This month, Joker continues to be the most prevalent mobile malware, while RansomHub remains the leading ransomware group, both maintaining their positions from the previous month. These findings highlight the persistent threats posed by these malicious entities in the evolving cyber security landscape.

- ↑ NJRat – NJRat is a remote accesses Trojan, targeting mainly government agencies and organizations in the Middle East. The Trojan has first emerged on 2012 and has multiple capabilities: capturing keystrokes, accessing the victim’s camera, stealing credentials stored in browsers, uploading and downloading files, performing process and file manipulations, and viewing the victim’s desktop. NJRat infects victims via phishing attacks and drive-by downloads, and propagates through infected USB keys or networked drives, with the support of Command & Control server software.
- ↑ Glupteba – Known since 2011, Glupteba is a backdoor that 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.
- ↑ AsyncRat – Asyncrat is a Trojan that targets the Windows platform. This malware sends out system information about the targeted system to a remote server. It receives commands from the server to download and execute plugins, kill processes, uninstall/update itself, and capture screenshots of the infected system.
Top exploited vulnerabilities
- ↔ Command Injection Over HTTP (CVE-2021-43936, CVE-2022-24086) – A command Injection over HTTP vulnerability has been reported. A remote attacker can exploit this issue by sending a specially crafted request to the victim. Successful exploitation would allow an attacker to execute arbitrary code on the target machine.
- ↑ Web Servers Malicious URL Directory Traversal (CVE-2010-4598, CVE-2011-2474,CVE-2014-0130,CVE-2014-0780,CVE-2015-0666,CVE-2015-4068,CVE-2015-7254,CVE-2016-4523,CVE-2016-8530,CVE-2017-11512,CVE-2018-3948,CVE-2018-3949,CVE-2019-18952,CVE-2020-5410,CVE-2020-8260) – There exists a directory traversal vulnerability On different web servers. The vulnerability is due to an input validation error in a web server that does not properly sanitize the URI for the directory traversal patterns. Successful exploitation allows unauthenticated remote attackers to disclose or access arbitrary files on the vulnerable server.
