Check Point reveals top threats and targeted industries for February 2023

Check Point Software Technologies, a provider of cybersecurity solutions globally, has published its Global Threat Index for February 2023.

Last month saw the Remcos Trojan return to the top ten list for the first time since December 2022 after it was reported being used by threat actors to target Ukranian government entities through phishing attacks.

Meanwhile, Emotet Trojan and Formbook Infostealer climbed the ranking taking second and third place respectively, while Education/Research remained the most targeted industry.

Despite researchers identifying a 44% decrease in the average number of weekly attacks per organisation between October 2022 and February 2023, Ukraine remains a popular target for cyber criminals, following the Russian invasion, the report finds.

In the most recent campaign, attackers impersonated Ukrtelecom JSC in a mass email distribution, using a malicious RAR attachment to spread the Remcos Trojan, which has returned to the top malware list for the first time since October 2022.

Once installed, the tool opens a backdoor on the compromised system, allowing full access to the remote user for activities such as data exfiltration and command execution.

The ongoing attacks are believed to be linked to cyberespionage operations due to the behaviour patterns and offensive capabilities of the incidents.

Maya Horowitz, VP Research at Check Point Software, says, "While there has been a decrease in the number of politically motivated attacks on Ukraine, they remain a battleground for cyber criminals. Hacktivism has typically been high on the agenda for threat actors since the Russo-Ukrainian war began and most have favored disruptive attack methods such as DDoS to garner the most publicity.

"However, the latest campaign used a more traditional route of attack, using phishing scams to obtain information and extract data.

"It's important that all organizations and government bodies follow safe security practices when receiving and opening emails. Do not download attachments without scanning the properties first. Avoid clicking on links within the body of the email and check the sender address for any abnormalities such as additional characters or misspellings."

CPR also revealed that Web Servers Malicious URL Directory Traversal was the most exploited vulnerability, impacting 47% of organisations globally. This was followed by Web Server Exposed Git Repository Information Disclosure which impacted 46% of organisations worldwide while Apache Log4j Remote Code Execution is the third most used vulnerability, with a global impact of 45%.

Top malware families

Overall, Check Point finds Qbot was the most prevalent malware last month with an impact of more than 7% on worldwide organizations respectively, followed by Formbook at 5% and Emotet with 4%.

• Qbot: Qbot AKA Qakbot is a banking Trojan that first appeared in 2008. It was designed to steal a users banking credentials or keystrokes and is often distributed via spam emails. Qbot employs several anti-VM, anti-debugging and anti-sandbox techniques to hinder analysis and evade detection.
• FormBook: FormBook is an Infostealer targeting Windows OS and was first detected in 2016. It is marketed as Malware as a Service (MaaS) in underground hacking forums for its strong evasion techniques and relatively low price. Formbook harvests credentials from various web browsers, collects screenshots, monitors and logs keystrokes and can download and execute files according to orders from its C&C.
• Emotet: Emotet is an advanced, self-propagating and modular Trojan. Emotet used to be employed as a banking Trojan but has recently been used as a distributor to other malware or malicious campaigns. It uses multiple methods for maintaining persistence and evasion techniques to avoid detection. In addition, it can be spread through phishing spam emails containing malicious attachments or links.

Top attacked industries globally: Last month, Education/Research remained the most attacked industry globally, followed by Government/Military and then Healthcare.

Top exploited vulnerabilities

Last month 'Web Servers Malicious URL Directory Traversal' was the most exploited vulnerability, impacting 47% of organisations globally.

This was followed by 'Web Server Exposed Git Repository Information Disclosure' which impacted 46% of organisations worldwide while 'Apache Log4j Remote Code Execution' is the third most used vulnerability, with a global impact of 45%.

• Web Servers Malicious URL Directory Traversal: 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.
• Web Server Exposed Git Repository Information Disclosure: An information disclosure vulnerability has been reported in Git Repository. Successful exploitation of this vulnerability could allow an unintentional disclosure of account information.
• Apache Log4j Remote Code Execution (CVE-2021-44228): A remote code execution vulnerability exists in Apache Log4j. Successful exploitation of this vulnerability could allow a remote attacker to execute arbitrary code on the affected system.

Top mobile malwares

Last month Anubis remained the most prevalent mobile malware, followed by Hiddad and AhMyth.

• Anubis: Anubis is a banking Trojan malware designed for Android mobile phones. Since it was initially detected, it has gained additional functions including Remote Access Trojan (RAT) functionality, keylogger, audio recording capabilities and various ransomware features. It has been detected on hundreds of different applications available in the Google Store.
• 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.
• AhMyth: AhMyth is a Remote Access Trojan (RAT) discovered in 2017. It is distributed through Android apps that can be found on app stores and various websites. When a user installs one of these infected apps, the malware can collect sensitive information from the device and perform actions such as keylogging, taking screenshots, sending SMS messages, and activating the camera.
