Check Point’s latest Threat Index has revealed RansomHub has remained the most prevalent Ransomware group. Meanwhile, researchers identified a Remcos Windows malware campaign exploiting a recent security software update

Our last Global Threat Index for June 2024 revealed significant changes in ransomware rankings. Despite a significant drop in June, LockBit re-emerged last month to become the second most prevalent ransomware group, while RansomHub retained the top spot. Meanwhile, researchers identified both a campaign distributing Remcos malware following a CrowdStrike update issue, and a series of new FakeUpdates tactics, which once again ranked first on the top malware list for July.

An issue in the CrowdStrike Falcon sensor for Windows led to cybercriminals distributing a malicious ZIP file named crowdstrike-hotfix.zip. This file contained HijackLoader, which subsequently activated Remcos malware, ranked as the seventh most wanted malware in July. The campaign targeted businesses using Spanish-language instructions and involved the creation of fake domains for phishing attacks.

Meanwhile, researchers uncovered a series of new tactics employing FakeUpdates, which topped the malware ranking for another month. Users visiting compromised websites encountered fake browser update prompts, leading to the installation of Remote Access Trojans (RATs) like AsyncRAT, currently ranked ninth on Check Point’s index. Alarmingly, cyber criminals have now started exploiting BOINC, a platform meant for volunteer computing, to gain remote control over infected systems.

Cyber criminals are always looking for ways to innovate malware distribution to bypass security measures and take advantage of vulnerabilities. It is important that organizations take extra precautions to avoid downtime, such as implementing preventative security measures and keeping offline back-ups for quicker recovery.

Top malware families

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

FakeUpdates was the most prevalent malware last month with an impact of 7% worldwide organizations, followed by Androxgh0st with a global impact of 5%, and AgentTesla with a global impact of 3%.

  1. ↔ FakeUpdates – FakeUpdates (AKA SocGholish) is a downloader written in JavaScript. It writes the payloads to disk prior to launching them. FakeUpdates led to further compromise via many additional malware, including GootLoader, Dridex, NetSupport, DoppelPaymer, and AZORult.
  2. ↔ Androxgh0st – Androxgh0st is a botnet that targets Windows, Mac, and Linux platforms. For initial infection, Androxgh0st exploits multiple vulnerabilities, specifically targeting- the PHPUnit, Laravel Framework, and Apache Web Server. The malware steals sensitive information such as Twilio account information, SMTP credentials, AWS key, etc. It uses Laravel files to collect the required information. It has different variants which scan for different information.
  3. ↔ AgentTesla – AgentTesla 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).
  4. ↑ Formbook – Formbook is an Infostealer targeting the 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.
  5. ↓ Qbot – Qbot AKA Qakbot is a multipurpose malware that first appeared in 2008. It was designed to steal a user’s credentials, record keystrokes, steal cookies from browsers, spy on banking activities, and deploy additional malware. Often distributed via spam email, Qbot employs several anti-VM, anti-debugging, and anti-sandbox techniques to hinder analysis and evade detection. Commencing in 2022, it emerged as one of the most prevalent Trojans.
  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. ↔ Phorpiex – Phorpiex is a botnet known for distributing other malware families via spam campaigns as well as fueling large scale Sextortion campaigns.
  8. ↑ Vidar- Vidar is an infostealer malware operating as malware-as-a-service that was first discovered in the wild in late 2018. The malware runs on Windows and can collect a wide range of sensitive data from browsers and digital wallets. Additionally, malware is used as a downloader for ransomware.
  9. ↓ 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.
  10. ↓ 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.

Top Ransomware Groups

The data is based on insights from ransomware “shame sites” run by double-extortion ransomware groups which posted victim information. RansomHub is the most prevalent ransomware group this month, responsible for 11% of the published attacks, followed by Lockbit3 with 8% and Akira with 6% .

  1. RansomHub – RansomHub is a Ransomware-as-a-Service (RaaS) operation that emerged as a rebranded version of the previously known Knight ransomware. Surfacing prominently in early 2024 in underground cyber crime forums, RansomHub has quickly gained notoriety for its aggressive campaigns targeting various systems including Windows, macOS, Linux, and particularly VMware ESXi environments. This malware is known for employing sophisticated encryption methods.
  2. Lockbit3 – LockBit is a ransomware, operating in a RaaS model, first reported in September 2019. LockBit targets large enterprises and government entities from various countries and does not target individuals in Russia or the Commonwealth of Independent States.
  3. Akira – Akira Ransomware, first reported in the beginning of 2023, targets both Windows and Linux systems. It uses symmetric encryption with CryptGenRandom() and Chacha 2008 for file encryption and is similar to the leaked Conti v2 ransomware. Akira is distributed through various means, including infected email attachments and exploits in VPN endpoints. Upon infection, it encrypts data and appends a “.akira” extension to file names, then presents a ransom note demanding payment for decryption.
