Introduction

With the increasing frequency and severity of cyber-attacks on critical sectors, the government of India has formulated the National Cyber Security Reference Framework (NCRF) 2023, aimed to address cybersecurity concerns in India. In today’s digital age, the security of critical sectors is paramount due to the ever-evolving landscape of cyber threats. Cybersecurity measures are crucial for protecting essential sectors such as banking, energy, healthcare, telecommunications, transportation, strategic enterprises, and government enterprises. This is an essential step towards safeguarding these critical sectors and preparing for the challenges they face in the face of cyber threats. Protecting critical sectors from cyber threats is an urgent priority that requires the development of robust cybersecurity practices and the implementation of effective measures to mitigate risks.

Overview of the National Cyber Security Policy 2013

The National Cyber Security Policy of 2013 was the first attempt to address cybersecurity concerns in India. However, it had several drawbacks that limited its effectiveness in mitigating cyber risks in the contemporary digital age. The policy’s outdated guidelines, insufficient prevention and response measures, and lack of legal implications hindered its ability to protect critical sectors adequately. Moreover, the policy should have kept up with the rapidly evolving cyber threat landscape and emerging technologies, leaving organisations vulnerable to new cyber-attacks. The 2013 policy failed to address the evolving nature of cyber threats, leaving organisations needing updated guidelines to combat new and sophisticated attacks.

As a result, an updated and more comprehensive policy, the National Cyber Security Reference Framework 2023, was necessary to address emerging challenges and provide strategic guidance for protecting critical sectors against cyber threats.

Highlights of NCRF 2023

Strategic Guidance: NCRF 2023 has been developed to provide organisations with strategic guidance to address their cybersecurity concerns in a structured manner.

Common but Differentiated Responsibility (CBDR): The policy is based on a CBDR approach, recognising that different organisations have varying levels of cybersecurity needs and responsibilities.

Update of National Cyber Security Policy 2013: NCRF supersedes the National Cyber Security Policy 2013, which was due for an update to align with the evolving cyber threat landscape and emerging challenges.

Different from CERT-In Directives: NCRF is distinct from the directives issued by the Indian Computer Emergency Response Team (CERT-In) published in April 2023. It provides a comprehensive framework rather than specific directives for reporting cyber incidents.

Combination of robust strategies: National Cyber Security Reference Framework 2023 will provide strategic guidance, a revised structure, and a proactive approach to cybersecurity, enabling organisations to tackle the growing cyberattacks in India better and safeguard critical sectors. Rising incidents of malware attacks on critical sectors

In recent years, there has been a significant increase in malware attacks targeting critical sectors. These sectors, including banking, energy, healthcare, telecommunications, transportation, strategic enterprises, and government enterprises, play a crucial role in the functioning of economies and the well-being of societies. The escalating incidents of malware attacks on these sectors have raised concerns about the security and resilience of critical infrastructure.

Banking: The banking sector handles sensitive financial data and is a prime target for cybercriminals due to the potential for financial fraud and theft.

Energy: The energy sector, including power grids and oil companies, is critical for the functioning of economies, and disruptions can have severe consequences for national security and public safety.

Healthcare: The healthcare sector holds valuable patient data, and cyber-attacks can compromise patient privacy and disrupt healthcare services. Malware attacks on healthcare organisations can result in the theft of patient records, ransomware incidents that cripple healthcare operations, and compromise medical devices.

Telecommunications: Telecommunications infrastructure is vital for reliable communication, and attacks targeting this sector can lead to communication disruptions and compromise the privacy of transmitted data. The interconnectedness of telecommunications networks globally presents opportunities for cybercriminals to launch large-scale attacks, such as Distributed Denial-of-Service (DDoS) attacks.

Transportation: Malware attacks on transportation systems can lead to service disruptions, compromise control systems, and pose safety risks.

Strategic Enterprises: Strategic enterprises, including defence, aerospace, intelligence agencies, and other sectors vital to national security, face sophisticated malware attacks with potentially severe consequences. Cyber adversaries target these enterprises to gain unauthorised access to classified information, compromise critical infrastructure, or sabotage national security operations.

Government Enterprises: Government organisations hold a vast amount of sensitive data and provide essential services to citizens, making them targets for data breaches and attacks that can disrupt critical services.

Conclusion  

The sectors of banking, energy, healthcare, telecommunications, transportation, strategic enterprises, and government enterprises face unique vulnerabilities and challenges in the face of cyber-attacks. By recognising the significance of safeguarding these sectors, we can emphasise the need for proactive cybersecurity measures and collaborative efforts between public and private entities.

Through these concerted efforts, we can create a safer digital environment for these sectors, protecting vital services and preserving the integrity of our economy and society. The rising incidents of malware attacks on critical sectors emphasise the urgent need for updated cybersecurity policy, enhanced cybersecurity measures, a collaboration between public and private entities, and the development of proactive defence strategies. National Cyber Security Reference Framework 2023 will help in addressing the evolving cyber threat landscape, protect critical sectors, fill the gaps in sector-specific best practices, promote collaboration, establish a regulatory framework, and address the challenges posed by emerging technologies. By providing strategic guidance, this framework will enhance organisations’ cybersecurity posture and ensure the protection of critical infrastructure in an increasingly digitised world.

Introduction

Recently the attackers employed the CVE-2017-0199 vulnerability in Microsoft Office to deliver a fileless form of the Remcos RAT. The Remcos RAT makes the attacker have full control of the systems that have been infected by this malware. This research will give a detailed technical description of the identified vulnerability, attack vector, and tactics together with the practical steps to counter the identified risks.

The Targeted Malware: Remcos RAT

Remcos RAT (Remote Control & Surveillance) is a commercially available remote access tool designed for legitimate administrative use. However, it has been widely adopted by cybercriminals for its stealth and extensive control capabilities, enabling:

• System control and monitoring
• Keylogging
• Data exfiltration
• Execution of arbitrary commands

The fileless variant utilised in this campaign makes detection even more challenging by running entirely in system memory, leaving minimal forensic traces.

Attack Vector: Phishing with Malicious Excel Attachments

The phishing email will be sent which appears as legitimate business communication, such as a purchase order or invoice. This email contains an Excel attachment that is weaponized to exploit the CVE-2017-0199 vulnerability.

Technical Analysis: CVE-2017-0199 Exploitation

Vulnerability Assessment

• CVE-2017-0199 is a Remote Code Execution (RCE) vulnerability in Microsoft Office which uses Object Linking and Embedding (OLE) objects.
• Affected Components:some text
  • Microsoft Word
  • Microsoft Excel
  • WordPad
• CVSS Score: 7.8 (High Severity)

Mechanism of Exploitation

The vulnerability enables attackers to craft a malicious document when opened, it fetches and executes an external payload via an HTML Application (HTA) file. The execution process occurs without requiring user interaction beyond opening the document.

Detailed Exploitation Steps

1. Phishing Email and Malicious Document some text
   • The email contains an Excel file designed to make use of CVE-2017-0199.
   • When the email gets opened, the document automatically connects to a remote server (e.g., 192.3.220[.]22) to download an HTA file (cookienetbookinetcache.hta).
2. Execution via mshta.exe some text
   • The downloaded HTA file is executed using mshta.exe, a legitimate Windows process for running HTML Applications.
   • This execution is seamless and does not prompt the user, making the attack stealthy.
3. Multi-Layer Obfuscation some text
   • The HTA file is wrapped in several layers of scripting, including: some text
     • JavaScript
     • VBScript
     • PowerShell
   • This obfuscation helps evade static analysis by traditional antivirus solutions.
4. Fileless Payload Deployment some text
   • The downloaded executable leverages process hollowing to inject malicious code into legitimate system processes.
   • The Remcos RAT payload is loaded directly into memory, avoiding the creation of files on disk.

Fileless Malware Techniques

1. Process Hollowing
The attack replaces the memory of a legitimate process (e.g., explorer.exe) with the malicious Remcos RAT payload. This allows the malware to:

• Evade detection by blending into normal system activity.
• Run with the privileges of the hijacked process.

2. Anti-Analysis Techniques

• Anti-Debugging: Detects the presence of debugging tools and terminates malicious processes if found.
• Anti-VM and Sandbox Evasion: Ensures execution only on real systems to avoid detection during security analysis.

3. In-Memory Execution

• By running entirely in system memory, the malware avoids leaving artifacts on the disk, making forensic analysis and detection more challenging.

Capabilities of Remcos RAT

Once deployed, Remcos RAT provides attackers with a comprehensive suite of functionalities, including:

• Data Exfiltration: some text
  • Stealing system information, files, and credentials.
• Remote Execution: some text
  • Running arbitrary commands, scripts, and additional payloads.
• Surveillance: some text
  • Enabling the camera and microphone.
  • Capturing screen activity and clipboard contents.
• System Manipulation: some text
  • Modifying Windows Registry entries.
  • Controlling system services and processes.
  • Disabling user input devices (keyboard and mouse).

Advanced Phishing Techniques in Parallel Campaigns

1. DocuSign Abuse
Attackers exploit legitimate DocuSign APIs to create authentic-looking phishing invoices. These invoices can trick users into authorising payments or signing malicious documents, bypassing traditional email security systems.

2. ZIP File Concatenation
By appending multiple ZIP archives into a single file, attackers exploit inconsistencies in how different tools handle these files. This allows them to embed malware that evades detection by certain archive managers.

Broader Implications of Fileless Malware

Fileless malware like Remcos RAT poses significant challenges:

• Detection Difficulties: Traditional signature-based antivirus systems struggle to detect fileless malware, as there are no static files to scan.
• Forensic Limitations: The lack of disk artifacts complicates post-incident analysis, making it harder to trace the attack's origin and scope.
• Increased Sophistication: These campaigns demonstrate the growing technical prowess of cybercriminals, leveraging legitimate tools and services for malicious purposes.

Mitigation Strategies

1. Patch Management some text
   • It is important to regularly update software to address known vulnerabilities like CVE-2017-0199. Microsoft released a patch for this vulnerability in April 2017.
2. Advanced Email Security some text
   • It is important to implement email filtering solutions that can detect phishing attempts, even those using legitimate services like DocuSign.
3. Endpoint Detection and Response (EDR)some text
   • Always use EDR solutions to monitor for suspicious behavior, such as unauthorized use of mshta.exe or process hollowing.
4. User Awareness and Training some text
   • Educate users about phishing techniques and the risks of opening unexpected attachments.
5. Behavioral Analysis some text
   • Deploy security solutions capable of detecting anomalous activity, even if no malicious files are present.

Conclusion

The attack via CVE-2017-0199 further led to the injection of a new fileless variant of Remcos RAT, proving how threats are getting more and more sophisticated. Thanks to the improved obfuscation and the lack of files, the attackers eliminate all traditional antiviral protection and gain full control over the infected computers. It is real and organisations have to make sure that they apply patches on time, that they build better technologies for detection and that the users themselves are more wary of the threats.

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.
