SharpRhino RAT: Advanced Threat Hidden in Legitimate Software
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.

Introduction
The pervasive issue of misinformation in India is a multifaceted challenge with profound implications for democratic processes, public awareness, and social harmony. The Election Commission of India (ECI) has taken measures to counter misinformation during the 2024 elections. ECI has launched campaigns to educate people and urge them to verify election-related content and share responsibly on social media. In response to the proliferation of fake news and misinformation online, the ECI has introduced initiatives such as ‘Myth vs. Reality’ and 'VerifyBeforeYouAmplify' to clear the air around fake news being spread on social media. EC measures aim to ensure that the spread of misinformation is curbed, especially during election time, when voters consume a lot of information from social media. It is of the utmost importance that voters take in facts and reliable information and avoid any manipulative or fake information that can negatively impact the election process.
EC Collaboration with Tech Platforms
In this new age of technology, the Internet and social media continue to witness a surge in the spread of misinformation, disinformation, synthetic media content, and deepfake videos. This has rightly raised serious concerns. The responsible use of social media is instrumental in maintaining the accuracy of information and curbing misinformation incidents.
The ECI has collaborated with Google to empower the citizenry by making it easy to find critical voting information on Google Search and YouTube. In this way, Google supports the 2024 Indian General Election by providing high-quality information to voters, safeguarding platforms from abuse, and helping people navigate AI-generated content. The company connects voters to helpful information through product features that show data from trusted organisations across its portfolio. YouTube showcases election information panels, including how to register to vote, how to vote, and candidate information. YouTube's recommendation system prominently features content from authority sources on the homepage, in search results, and in the "Up Next" panel. YouTube highlights high-quality content from authoritative news sources during key moments through its Top News and Breaking News shelves, as well as the news watch page.
Google has also implemented strict policies and restrictions regarding who can run election-related advertising campaigns on its platforms. They require all advertisers who wish to run election ads to undergo an identity verification process, provide a pre-certificate issued by the ECI or anyone authorised by the ECI for each election ad they want to run where necessary, and have in-ad disclosures that clearly show who paid for the ad. Additionally, they have long-standing ad policies that prohibit ads from promoting demonstrably false claims that could undermine trust or participation in elections.
CyberPeace Countering Misinformation
CyberPeace Foundation, a leading organisation in the field of cybersecurity works to promote digital peace for all. CyberPeace is working on the wider ecosystem to counter misinformation and develop a safer and more responsible Internet. CyberPeace has collaborated with Google.org to run a pan-India awareness-building program and comprehensive multilingual digital resource hub with content available in up to 15 Indian languages to empower over 40 million netizens in building resilience against misinformation and practising responsible online behaviour. This step is crucial in creating a strong foundation for a trustworthy Internet and secure digital landscape.
Myth vs Reality Register by ECI
The Election Commission of India (ECI) has launched the 'Myth vs Reality Register' to combat misinformation and ensure the integrity of the electoral process during the general elections 2024. The 'Myth vs Reality Register' can be accessed through the Election Commission's official website (https://mythvsreality.eci.gov.in/). All stakeholders are urged to verify and corroborate any dubious information they receive through any channel with the information provided in the register. The register provides a one-stop platform for credible and authenticated election-related information, with the factual matrix regularly updated to include the latest busted fakes and fresh FAQs. The ECI has identified misinformation as one of the challenges, along with money, muscle, and Model Code of Conduct violations, for electoral integrity. The platform can be used to verify information, prevent the spread of misinformation, debunk myths, and stay informed about key issues during the General Elections 2024.
The ECI has taken proactive steps to combat the challenge of misinformation which could cripple the democratic process. EC has issued directives urging vigilance and responsibility from all stakeholders, including political parties, to verify information before amplifying it. The EC has also urged responsible behaviour on social media platforms and discourse that inspires unity rather than division. The commission has stated that originators of false information will face severe consequences, and nodal officers across states will remove unlawful content. Parties are encouraged to engage in issue-based campaigning and refrain from disseminating unverified or misleading advertisements.
Conclusion
The steps taken by the ECI have been designed to empower citizens and help them affirm the accuracy and authenticity of content before amplifying it. All citizens must be well-educated about the entire election process in India. This includes information on how the electoral rolls are made, how candidates are monitored, a complete database of candidates and candidate backgrounds, party manifestos, etc. For informed decision-making, active reading and seeking information from authentic sources is imperative. The partnership between government agencies, tech platforms and civil societies helps develop strategies to counter the widespread misinformation and promote online safety in general, and electoral integrity in particular.

Introduction
Rajeev Chandrasekhar, Minister of State at the Ministry of Electronics and Information Technology, has emphasised the need for an open internet. He stated that no platform can deny content creators access to distribute and monetise content and that large technology companies have begun to play a significant role in the digital evolution. Chandrasekhar emphasised that the government does not want the internet or monetisation to be in the purview of just one or two companies and does not want 120 crore Indians on the internet in 2025 to be catered to by big islands on the internet.
The Voice for Open Internet
India's Minister of State for IT, Rajeev Chandrasekhar, has stated that no technology company or social media platform can deny content creators access to distribute and monetise their content. Speaking at the Digital News Publishers Association Conference in Delhi, Chandrasekhar emphasized that the government does not want the internet or monetization of the internet to be in the hands of just one or two companies. He argued that the government does not like monopoly or duopoly and does not want 120 crore Indians on the Internet in 2025 to be catered to by big islands on the internet.
Chandrasekhar highlighted that large technology companies have begun to exert influence when it comes to the dissemination of content, which has become an area of concern for publishers and content creators. He stated that if any platform finds it necessary to block any content, they need to give reasons or grounds to the creators, stating that the content is violating norms.
As India tries to establish itself as an innovator in the technology sector, a recent corpus of Rs 1 lakh crore was announced by the government in the interim Budget of 2024-25. As big companies continue to tighten their stronghold on the sector, content moderation has become crucial. Under the IT Rules Act, 11 types of categories are unlawful under IT Act and criminal law. Platforms must ensure no user posts content that falls under these categories, take down any such content, and gateway users to either de-platforming or prosecuting. Chandrasekhar believes that the government has to protect the fundamental rights of people and emphasises legislative guardrails to ensure platforms are accountable for the correctness of the content.
Monetizing Content on the Platform
No platform can deny a content creator access to the platform to distribute and monetise it,' Chandrasekhar declared, boldly laying down a gauntlet that defies the prevailing norms. This tenet signals a nascent dawn where creators may envision reaping the rewards borne of their creative endeavours unfettered by platform restrictions.
An increasingly contentious issue that shadows this debate is the moderation of content within the digital realm. In this vast uncharted expanse, the powers that be within these monolithic platforms assume the mantle of vigilance—policing the digital avenues for transgressions against a conscribed code of conduct. Under the stipulations of India's IT Rules Act, for example, platforms are duty-bound to interdict user content that strays into territories encompassing a spectrum of 11 delineated unlawful categories. Violations span the gamut from the infringement of intellectual property rights to the propagation of misinformation—each category necessitating swift and decisive intervention. He raised the alarm against misinformation—a malignant growth fed by the fertile soils of innovation—a phenomenon wherein media reports chillingly suggest that up to half of the information circulating on the internet might be a mere fabrication, a misleading simulacrum of authenticity.
The government's stance, as expounded by Chandrasekhar, pivots on an axis of safeguarding citizens' fundamental rights, compelling digital platforms to shoulder the responsibility of arbiters of truth. 'We are a nation of over 90 crores today, a nation progressing with vigour, yet we find ourselves beset by those who wish us ill,'
Upcoming Digital India Act
Awaiting upon the horizon, India's proposed Digital India Act (DIA), still in its embryonic stage of pre-consultation deliberation, seeks to sculpt these asymmetries into a more balanced form. Chandrasekhar hinted at the potential inclusion within the DIA of regulatory measures that would sculpt the interactions between platforms and the mosaic of content creators who inhabit them. Although specifics await the crucible of public discourse and the formalities of consultation, indications of a maturing framework are palpable.
Conclusion
It is essential that the fable of digital transformation reverberates with the voices of individual creators, the very lifeblood propelling the vibrant heartbeat of the internet's culture. These are the voices that must echo at the centre stage of policy deliberations and legislative assembly halls; these are the visions that must guide us, and these are the rights that we must uphold. As we stand upon the precipice of a nascent digital age, the decisions we forge at this moment will cascade into the morrow and define the internet of our future. This internet must eternally stand as a bastion of freedom, of ceaseless innovation and as a realm of boundless opportunity for every soul that ventures into its infinite expanse with responsible use.

Key points: Data collection, Protecting Children, and Awareness
Introduction
The evolution of technology has drastically changed over the period impacting mankind and their lifestyle. For every single smallest aspect, humans are reliable on the computers they have manufactured. The use of AI has almost hindered mankind, kids these days are more lethargic to work and write more sensibly on their own, but they are more likely interested in television, video games, mobile games, etc. School kids use AI just to complete their homework. Is it a good sign for the country’s future? The study suggests that Tools like ChatGPT is a threat to humans/a child’s potential to be creative and make original content requiring a human writer’s insight. Tools like ChatGPT can remove students’ artistic voices rather than using their unique writing style.
Does any of those browsers or search engines use your search history against you? or How do non-users tend to lose their private info on such a search engine?
Are there any safety measures that one’s the government of a particular country taking to protect their people’s rights?
Some of us might wonder how these two fancy-looking world merge and into, Arey they a boon or curse?
So here’s the top news getting flooded all over the world through the internet,
“Italian Agency impose strict measures on OpenAI’s ChatGPT”
Italy becomes the first Western European country to take serious measures about using Open AI ChatGPT. An Italian Data Protection agency named Garante has set mandates on ChatGPT. Garante has raised concerns about privacy violations and the inability to verify the age of users. Garate has also claimed that the AI ChatBot is violating the EU’s General Data Protection Regulation (GDPR). In a press release, Garante demanded OpenAI take necessary actions.
To begin with, Garante has demanded that OpenAI’s ChatGPT should increase its transparency and give a comprehensive statement about its data processing practices. OpenAI must specify between obtaining user consent for processing users’ data to train its AI model or may rely on a legitimate basis. OpenAI must maintain the privacy of users’ data.
In addition, ChatGPT should also take measures to prevent minors from accessing the technology at such an early stage of life, which could hinder their brain power. ChatGPT should add some age verification system to prevent minors from accessing explicit content. Moreover, Garante suggests that OpenAI should spread awareness among its users about their data being processed to train its AI model. Garante has set a deadline of April 30 for ChatGPT to complete the given tasks. Until then, its service should be banned in the country.
Child safety while surfing on ChatGpt
Italian agency demands age limitation to surf and an age verification method to exclude users under the age of 13, and parental authority should be required for users between the ages of 13 and 18. As this is a matter of security. Children might get exposed to explicit content invalidated to their age or explore illegitimate content. The AI chatbot doesn’t have the sense to determine which content is appropriate for the underage audience. Due to tools like chatbots, subjective things/information are already available to young students, leading to endangered irrespective of their future. As ChatGpt can hinder their potential and ability to create original and creative content for young minds. It is a threat motivation to humans’ motivation to write. Moreover, when students need time to think and analyze they get lethargic due to tools like ChatGPT, and the practice they need fades away.
Collection of User’s Data
According to some reports from the company’s privacy policy, OpenAI ChatGpt collects an assortment of additional data. The first two questions are for a free trial when a session starts. It asks for your Login, and SignUp through your Gmail account collects your IP address, browser type, and the data you put in the form of input, i.e. it collects data on the user’s interaction with the website, It also collects the user’s data like session time, cookies through third party may tend to sell it to an unspecified third party.
This snapshot shows that they have added a few things after Garante’s draft.
Conclusion
AI chatbot – Chatgpt is an advanced technology tool that makes work a little easier, but one surfing on such tools must stay aware of the information they are asking for. Such AI bots are trained to understand mankind, its job is to give a helping hand and not doltish. In case of this, some people tend to provide sensitive information unknowingly, young minds get exposed to explicit information. Such bots need to put some age limitations. Such innovations keep taking place, but it’s individuals’ responsibility what actions to be allowed to access their online connected device. Unlike the Italian Agency, which has taken some preventive measures to keep their user’s data safe, also looking at the adverse effect of such chatbots on a young mind.
