#FactCheck - Viral Photos Falsely Linked to Iranian President Ebrahim Raisi's Helicopter Crash

March 3rd 2023, New Delhi: If you have received any message that contains a link asking users to download an application to avail Income Tax Refund or KYC benefits with the name of Income Tax Department or reputed Banks, Beware!

CyberPeace Foundation and Autobot Infosec Private Limited along with the academic partners under CyberPeace Center of Excellence (CCoE) recently conducted five different studies on phishing campaigns that have been circulating on the internet by using misleading tactics to convince users to install malicious applications on their devices. The first campaign impersonates the Income Tax Department, while the rest of the campaigns impersonate ICICI Bank, State Bank of India, IDFC Bank and Axis bank respectively. The phishing campaigns aim to trick users into divulging their personal and financial information.

After a detailed study, the research team found that:

• All campaigns appear to be an offer from reputed entities, however hosted on third-party domains instead of the official website of the Income Tax Department or the respective Banks, raising suspicion.
• The applications ask several access permissions of the device. Moreover some of them seek users to provide full control of the device. Allowing such access permission could result in a complete compromise of the system, including access to sensitive information such as microphone recordings, camera footage, text messages, contacts, pictures, videos, and even banking applications.
• Cybercriminals created malicious applications using icons that closely resemble those of legitimate entities with the intention of enticing users into downloading the malicious applications.
• The applications collect user’s personal and banking information. Getting into this type of trap could lead users to face significant financial losses.
• While investigating the impersonated Income Tax Department’s application, the Research team identified the application sends http traffic to a remote server which acts as a Command and Control (CnC/C2) for the application.
• Customers who desire to avail benefits or refunds from respective banks, download relevant apps, believing that the chosen app will assist them. However, they are not always aware that the app may be fraudulent.

“The Research highlights the importance of being vigilant while browsing the internet and not falling prey to such phishing attacks. It is crucial to be cautious when clicking on links or downloading attachments from unknown sources, as they may contain malware that can harm the device or compromise the data.” spokesperson, CyberPeace added.

In addition to this in an earlier report released in last month, the same research team had drawn attention to the WhatsApp messages masquerading as an offer from Tanishq Jewellers with links luring unsuspecting users with the promise of free valentine’s day  presents making the rounds on the app.

CyberPeace Advisory:

• The Research team recommends that people should avoid opening such messages sent via social platforms. One must always think before clicking on such links, or downloading any attachments from unauthorised sources.
• Downloading any application from any third party sources instead of the official app store should be avoided. This will greatly reduce the risk of downloading a malicious app, as official app stores have strict guidelines for app developers and review each app before it gets published on the store.
• Even if you download the application from an authorised source, check the app’s permissions before you install it. Some malicious apps may request access to sensitive information or resources on your device. If an app is asking for too many permissions, it’s best to avoid it.
• Keep your device and the app-store app up to date. This will ensure that you have the latest security updates and bug fixes.
• Falling into such a trap could result in a complete compromise of the system, including access to sensitive information such as microphone recordings, camera footage, text messages, contacts, pictures, videos, and even banking applications and could lead users to financial loss.
• Do not share confidential details like credentials, banking information with such types of Phishing scams.
• Never share or forward fake messages containing links on any social platform without proper verification.

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

In a setback to the Centre, the Bombay High Court on Friday 20th September 2024, struck down the provisions under IT Amendment Rules 2023, which empowered the Central Government to establish Fact Check Units (FCUs) to identify ‘fake and misleading’ information about its business on social media platforms. 

Chronological Overview

• On 6th April 2023, the Ministry of Electronics and Information Technology (MeitY) notified the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Amendment Rules, 2023 (IT Amendment Rules, 2023). These rules introduced new provisions to establish a fact-checking unit with respect to “any business of the central government”. This amendment was done In exercise of the powers conferred by section 87 of the Information Technology Act, 2000. (IT Act).
• On 20 March 2024, the Central Government notified the Press Information Bureau (PIB) as FCU under rule 3(1)(b)(v) of the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Amendment Rules 2023 (IT Amendment Rules 2023). 
• The next day on  21st March 2024, the Supreme Court stayed the Centre's decision on notifying PIB -FCU, considering the pendency of the proceedings before the High Court of Judicature at Bombay. A detailed analysis covered by CyberPeace on the Supreme Court Stay decision can be accessed here.
• In the latest development, the Bombay High Court on 20th September 2024, struck down the provisions under IT Amendment Rules 2023, which empowered the Central Government to establish Fact Check Units (FCUs) to identify ‘fake and misleading’ information about its business on social media platforms.  

Brief Overview of Bombay High Court decision dated 20th September 2024

Justice AS Chandurkar was appointed as the third judge after a split verdict in January 2023 by a division bench consisting of Justices Gautam Patel and Neela Gokhal.  As a Tie-breaker judge' Justice AS Chandurkar delivered the decision striking down provisions for setting up a Fact Check Unit under IT amendment 2023 rules. Striking down the Centre's proposed fact check unit provision, Justice A S Chandurkar of Bombay High Court also opined that there was no rationale to undertake an exercise in determining whether information related to the business of the Central govt was fake or false or misleading when in digital form but not doing the same when such information was in print. It was also contended that there is no justification to introduce an FCU only in relation to the business of the Central Government. Rule 3(1)(b)(v) has a serious chilling effect on the exercise of the freedom of speech and expression under Article 19(1)(a) of the Constitution since the communication of the view of the FCU will result in the intermediary simply pulling down the content for fear of consequences or losing the safe harbour provision given under IT Act.  

Justice Chandurkar held that the expressions ‘fake, false or misleading’ are ‘vague and overbroad’, and that the ‘test of proportionality’ is not satisfied. Rule 3(1)(b)(v), was violative of Articles 14 and 19 (1) (a) and 19 (1) (g) of the Constitution and it is “ultra vires”, or beyond the powers, of the IT Act.

Role of Expert Organisations in Curbing Mis/Disinformation and Fake News

In light of the recent developments, and the rising incidents of Mis/Disinformation and Fake News it becomes significantly important that we all stand together in the fight against these challenges. The actions against Mis/Disinformation and fake news should be strengthened by collective efforts, the expert organisations like CyberPeace Foundation plays an key role in enabling and encouraging netizens to exercise caution and rely on authenticated sources, rather than solely rely on govt FCU to block the content. 

Mis/Disinformation and Fake News should be stopped, identified and countered by netizens at the very first stage of its spread. In light of the Bombay High Court's decision to stuck down the provision related to setting up the FCU by the Central Government, it entails that the government's intention to address misinformation related solely to its business/operations may not have been effectively communicated in the eyes of the judiciary.

It is high time to exercise collective efforts against Mis/Disinformation and Fake News and support expert organizations who are actively engaged in conducting proactive measures, and campaigns to target these challenges, specifically in the online information landscape. CyberPeace actively publishes fact-checking reports and insights on Prebunking and Debunking, conducts expert sessions and takes various key steps aimed at empowering netizens to build cognitive defences to recognise the susceptible information, disregard misleading claims and prevent further spreads to ensure the true online information landscape.
