Check Point Research reports that Trickbot, often used in the initial stages of ransomware attacks, is the most prevalent malware for the second month running
Check Point Research (CPR), the Threat Intelligence arm of Check Point Software Technologies Ltd., a leading provider of cybersecurity solutions globally, has published its latest Global Threat Index for June 2021. Researchers report that Trickbot is still the most prevalent malware, having first taken the top spot in May.
Trickbot 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. Last month CPR reported that the average weekly number of ransomware attacks increased 93% over the past 12 months, and also warned that ransomware attacks often don’t start with ransomware. For example, in the Ryuk ransomware attacks, the Emotet malware was used to infiltrate the network, which was then infected with this month’s top malware, Trickbot, before the ransomware finally encrypted the data.
Since the Emotet botnet was taken down in January, the Trickbot Trojan and botnet has gained popularity. It has also recently been linked to a new ransomware strain called ‘Diavol’. Trickbot 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.
“Well-known ransomware groups such as Ryuk and REvil first rely on various forms of malware for the initial stages of infection – a key one being this month’s top malware, Trickbot,” said Maya Horowitz, Director, Threat Intelligence & Research, Products at Check Point. “Organizations need to remain acutely aware of the risks and ensure adequate solutions are in place. In addition to the botnet and banking trojan, Trickbot, this month’s list includes a big range of different malware types including botnets, infostealers, backdoors, RATs, and mobile. It’s crucial for organizations to have the right technologies in place to deal with such a wide variety of threats. If they do, the majority of attacks, even the most advanced ones such as REvil, can be prevented without disrupting the normal business flow.”
CPR also revealed this month “HTTP Headers Remote Code Execution” is the most commonly exploited vulnerability, impacting 47% of organizations globally, followed by “MVPower DVR Remote Code Execution” which impacts 45% of organizations worldwide. “Dasan GPON Router Authentication Bypass” takes third place in the top exploited vulnerabilities list, with a global impact of 44%.

Top exploited vulnerabilities
This month “HTTP Headers Remote Code Execution” is the most commonly exploited vulnerability, impacting 47% of organizations globally, followed by “MVPower DVR Remote Code Execution” which impacts 45% of organizations worldwide. “Dasan GPON Router Authentication Bypass” takes third place in the top exploited vulnerabilities list, with a global impact of 44%.
- ↑ HTTP Headers Remote Code Execution (CVE-2020-10826,CVE-2020-10827,CVE-2020-10828,CVE-2020-13756) – HTTP headers let the client and the server pass additional information with an HTTP request. A remote attacker may use a vulnerable HTTP header to run arbitrary code on the victim machine.
- ↑ MVPower DVR Remote Code Execution – A remote code execution vulnerability exists in MVPower DVR devices. A remote attacker can exploit this weakness to execute arbitrary code in the affected router via a crafted request.
- ↑ Dasan GPON Router Authentication Bypass (CVE-2018-10561) – An authentication bypass vulnerability exists in Dasan GPON routers. Successful exploitation of this vulnerability would allow remote attackers to obtain sensitive information and gain unauthorized access into the affected system.
Top mobile malwares
This month xHelper takes first place in the most prevalent mobile malware, followed by Hiddad and XLoader.
- xHelper – A malicious application seen in the wild since March 2019, used for downloading other malicious apps and display advertisements. The application is capable of hiding itself from the user, and can reinstall itself in the event that it was uninstalled.
- Hiddad – Hiddad is an Android malware which repackages legitimate apps and then releases them to a third-party store. Its main function is to display ads, but it can also gain access to key security details built into the OS.
- XLoader – XLoader is an Android Spyware and Banking Trojan developed by the Yanbian Gang, a Chinese hacker group. This malware uses DNS spoofing to distribute infected Android apps, in order to collect personal and financial information.
