#FactCheck -Scripted Video of Pre-Wedding Roka at Metro Station Misleads Users

Overview:

A recent addition to the  list of cybercrime  is SharpRhino, a RAT (Remote Access Trojan) actively used by Hunters International ransomware group. SharpRhino is highly developed and penetrates into the network mask of IT specialists, primarily due to the belief in the tools’ legitimacy. Going under the genuine software installer, SharpRhino started functioning in mid-June 2024. However, Quorum Cyber discovered it in early August 2024 while investigating ransomware.

About Hunters International Group:

Hunters International emerged as one of the most notorious groups focused on ransomware attacks, having compromised over 134 targets worldwide in the first seven months of 2024. It is believed that the group is the rebranding of Hive ransomware group that was previously active, and there are considerable similarities in the code. Its focus on IT employees in particular demonstrates the fact that they move tactically in gaining access to the organizations’ networks.

Modus Operandi:

1. Typosquatting Technique 

SharpRhino is mainly distributed by a domain that looks like the genuine Angry IP Scanner, which is a popular network discovery tool. The malware installer, labeled as ipscan-3.9.1-setup. It is a 32-bit Nullsoft installer which embeds a password protected 7z archive in it. 

2. Installation Process 

• Execution of Installer: When the victim downloads and executes the installer and changes the windows registry in order to attain persistence. This is done by generating a registry entry that starts a harmful file, Microsoft. AnyKey. exe, are fakes originating from fake versions of true legitimate Microsoft Visual Studio tools. 

• Creation of Batch File: This drops a batch file qualified as LogUpdate at the installer.bat, that runs the PowerShell scripts on the device. These scripts are to compile C# code into memory to serve as a means of making the malware covert in its operation. 

• Directory Creation: The installer establishes two directories that allow the C2 communication – C:\ProgramData\Microsoft: WindowsUpdater24 and LogUpdateWindows. 

3. Execution and Functionality: 

• Command Execution: The malware can execute PowerShell commands on the infected system, these actions may involve privilege escalation and other extended actions such as lateral movement. 

• C2 Communication: SharpRhino interacts with command and control servers located on domains from platforms such as Cloudflare. This communication is necessary for receiving commands from the attackers and for returning any data of interest to the attackers. 

• Data Exfiltration and Ransomware Deployment: Once SharpRhino has gained control, it can steal information and then proceed to encrypt it with a .locked extension. The procedure generally concludes with a ransom message, which informs users on how to purchase the decryption key. 

4. Propagation Techniques: 

Also, SharpRhino can spread through the self-copying method, this is the virus may copy itself to other computers using the network account of the victim and pretending to be trustworthy senders such as emails or network-shared files. Moreover, the victim’s machine may then proceed to propagate the malware to other systems like sharing in the company with other employees.

Indicators of Compromise (IOCs):

• LogUpdate.bat
• Wiaphoh7um.t
• ipscan-3.9.1-setup.exe
• kautix2aeX.t
• WindowsUpdate.bat

Command and Control Servers:

• cdn-server-1.xiren77418.workers.dev
• cdn-server-2.wesoc40288.workers.dev
• Angryipo.org
• Angryipsca.com

Precautionary measures to be taken:

To mitigate the risks posed by SharpRhino and similar malware, organizations should implement the following measures:

• Implement Security Best Practices: It is important only to download software from official sites and avoid similar sites to confuse the user by changing a few letters.

• Enhance Detection Capabilities: Use technology in detection that can detect the IOCs linked to Sharp Rhino.

• Educate Employees: Educate IT people and employees on phishing scams and the requirement to check the origin of the application.

• Regular Backups: It is also important to back up important files from systems and networks in order to minimize the effects of ransomware attacks on a business.

Conclusion:

SharpRhino could be deemed as the evolution of the strategies used by organizations like Hunters International and others involved in the distribution of ransomware. SharpRhino primarily focuses on the audience of IT professionals and employs complex delivery and execution schemes, which makes it an extremely serious threat for corporate networks. To do so it is imperative that organizations have an understanding of its inner workings in order to fortify their security measures against this relatively new threat. Through the enforcement of proper security measures and constant enlightenment of organizations on the importance of cybersecurity, firms can prevent the various risks associated with SharpRhino and related malware. Be safe, be knowledgeable, and most importantly, be secure when it comes to cyber security for your investments.

On June 5th, the world comes together to reflect on how the way we live impacts the environment.  We discuss conserving water, cutting back on plastic, and planting trees, but how often do we think about the environmental impact of our digital lives?

The internet is ubiquitous but invisible in a world that is becoming more interconnected by the day. It drives our communications, meetings, and recollections. However, there is a price for this digital convenience: carbon emissions.

A Digital Carbon Footprint: What Is It?

Electricity is necessary for every video we stream, email we send, and file we store on the cloud. But almost 60% of the electricity produced today is generated from burning fossil fuels. The digital world uses an incredible amount of energy, from the energy-hungry data centres that house our information to the networks that send it. Thus, the greenhouse gas emissions produced by our use of digital tools and services are referred to as our "digital carbon footprint." 

To put it in perspective:

• Up to 150–200 grams of CO₂ can be produced by streaming an hour-long HD video on your phone.

• A typical email sent can release about 4 grams of CO₂, and more if it contains attachments.
• Comparable to the airline industry, the internet as a whole accounts for 1.5% to 4% of global greenhouse gas emissions.

Why It Matters 

Ironically, despite the fact that digital life frequently feels "clean" and weightless, it is backed by enormous, power-hungry infrastructures. Additionally, our online activity is growing at a rapid pace as digital penetration increases. Plus, with the advent of AI and big data, the demand for energy is only going to rise. The harms of air, water, and soil degradation, and biodiversity loss are already upon us.  It's high time we reconsider how we use technology on World Environment Day.

What Can You Do? 

The good news is that even minor adjustments to our online conduct can have an impact.
