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 The policy’s outdated guidelines, insufficient prevention and response measures, and lack of legal implications hindered its ability to protect critical sectors adequately.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. Strengthening regulatory frameworks, sharing threat intelligence, and adopting best practices are essential to ensure our critical infrastructure’s resilience and security. 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.

SVIMS Director and Vice-Chancellor B. Vengamma lighting a lamp to formally launch the cybercrime awareness programme conducted by the police department for the medical students in Tirupati on Wednesday.

An awareness meet on safe Internet practices was held for the students of Sri Venkateswara University University (SVU) and Sri Venkateswara Institute of Medical Sciences (SVIMS) here on Wednesday.

“Cyber criminals on the prowl can easily track our digital footprint, steal our identity and resort to impersonation,” cyber expert I.L. Narasimha Rao cautioned the college students.

Addressing the students in two sessions, Mr. Narasimha Rao, who is a Senior Manager with CyberPeace Foundation, said seemingly common acts like browsing a website, and liking and commenting on posts on social media platforms could be used by impersonators to recreate an account in our name.

Turning to the youth, Mr. Narasimha Rao said the incognito mode and Virtual Private Network (VPN) used as a protected network connection do not ensure total privacy as third parties could still snoop over the websites being visited by the users. He also cautioned them tactics like ‘phishing’, ‘vishing’ and ‘smishing’ being used by cybercriminals to steal our passwords and gain access to our accounts.

“After cracking the whip on websites and apps that could potentially compromise our security, the Government of India has recently banned 232 more apps,” he noted.

Additional Superintendent of Police (Crime) B.H. Vimala Kumari appealed to cyber victims to call 1930 or the Cyber Mitra’s helpline 9121211100. SVIMS Director B. Vengamma stressed the need for caution with smartphones becoming an indispensable tool for students, be it for online education, seeking information, entertainment or for conducting digital transactions.

Executive Summary:

A new threat being uncovered in today’s threat landscape is that while threat actors took an average of one hour and seven minutes to leverage Proof-of-Concept(PoC) exploits after they went public, now the time is at a record low of 22 minutes. This incredibly fast exploitation means that there is very limited time for organizations’ IT departments to address these issues and close the leaks before they are exploited. Cloudflare released the Application Security report which shows that the attack percentage is more often higher than the rate at which individuals invent and develop security countermeasures like the WAF rules and software patches. In one case, Cloudflare noted an attacker using a PoC-based attack within a mere 22 minutes from the moment it was released, leaving almost no time for a remediation window. 

Despite the constant growth of vulnerabilities in various applications and systems, the share of exploited vulnerabilities, which are accompanied by some level of public exploit or PoC code, has remained relatively stable over the past several years and fluctuates around 50%. These vulnerabilities with publicly known exploit code, 41% was initially attacked in the zero-day mode while of those with no known code, 84% was first attacked in the same mode. 

Modus Operandi:

The modus operandi of the attack involving the rapid weaponization of proof-of-concept (PoC) exploits is characterized by the following steps:

• Vulnerability Identification: Threat actors bring together the exploitation of a system vulnerability that may be in the software or hardware of the system; this may be a code error, design failure, or a configuration error. This is normally achieved using vulnerability scanners and test procedures that have to be performed manually. 

• Vulnerability Analysis: After the vulnerability is identified, the attackers study how it operates to determine when and how it can be triggered and what consequences that action will have. This means that one needs to analyze the details of the PoC code or system to find out the connection sequence that leads to vulnerability exploitation. 

• Exploit Code Development: Being aware of the weakness, the attackers develop a small program or script denoted as the PoC that addresses exclusively the identified vulnerability and manipulates it in a moderated manner. This particular code is meant to be utilized in showing a particular penalty, which could be unauthorized access or alteration of data. 

• Public Disclosure and Weaponization: The PoC exploit is released which is frequently done shortly after the vulnerability has been announced to the public. This makes it easier for the attackers to exploit it while waiting for the software developer to release the patch. To illustrate, Cloudflare has spotted an attacker using the PoC-based exploit 22 minutes after the publication only. 

• Attack Execution: The attackers then use the weaponized PoC exploit to attack systems which are known to be vulnerable to it. Some of the actions that are tried in this context are attempts at running remote code, unauthorized access and so on. The pace at which it happens is often much faster than the pace at which humans put in place proper security defense mechanisms, such as the WAF rules or software application fixes. 

• Targeted Operations: Sometimes, they act as if it’s a planned operation, where the attackers are selective in the system or organization to attack. For example, exploitation of CVE-2022-47966 in ManageEngine software was used during the espionage subprocess, where to perform such activity, the attackers used the mentioned vulnerability to install tools and malware connected with espionage. 

Precautions: Mitigation

Following are the mitigating measures against the PoC Exploits: 

1. Fast Patching and New Vulnerability Handling 

• Introduce proper patching procedures to address quickly the security released updates and disclosed vulnerabilities. 

• Focus should be made on the patching of those vulnerabilities that are observed to be having available PoC exploits, which often risks being exploited almost immediately.

• It is necessary to frequently check for the new vulnerability disclosures and PoC releases and have a prepared incident response plan for this purpose. 

2. Leverage AI-Powered Security Tools 

•  Employ intelligent security applications which can easily generate desirable protection rules and signatures as attackers ramp up the weaponization of PoC exploits. 

• Step up use of artificial intelligence (AI) - fueled endpoint detection and response (EDR) applications to quickly detect and mitigate the attempts. 

• Integrate Artificial Intelligence based SIEM tools to Detect & analyze Indicators of compromise to form faster reaction. 

 3. Network Segmentation and Hardening 

• Use strong networking segregation to prevent the attacker’s movement across the network and also restrict the effects of successful attacks. 

• Secure any that are accessible from the internet, and service or protocols such as RDP, CIFS, or Active directory. 

• Limit the usage of native scripting applications as much as possible because cyber attackers may exploit them. 

4. Vulnerability Disclosure and PoC Management 

• Inform the vendors of the bugs and PoC exploits and make sure there is a common understanding of when they are reported, to ensure fast response and mitigation. 

• It is suggested to incorporate mechanisms like digital signing and encryption for managing and distributing PoC exploits to prevent them from being accessed by unauthorized persons. 

• Exploits used in PoC should be simple and independent with clear and meaningful variable and function names that help reduce time spent on triage and remediation. 

5. Risk Assessment and Response to Incidents 

• Maintain constant supervision of the environment with an intention of identifying signs of a compromise, as well as, attempts of exploitation. 

• Support a frequent detection, analysis and fighting of threats, which use PoC exploits into the system and its components. 

• Regularly communicate with security researchers and vendors to understand the existing threats and how to prevent them.

Conclusion:

The rapid process of monetization of Proof of Concept (POC) exploits is one of the most innovative and constantly expanding global threats to cybersecurity at the present moment. Cyber security experts must react quickly while applying a patch, incorporate AI to their security tools, efficiently subdivide their networks and always heed their vulnerability announcements. Stronger incident response plan would aid in handling these kinds of menaces. Hence, applying measures mentioned above, the organizations will be able to prevent the acceleration of turning PoC exploits into weapons and the probability of neutral affecting cyber attacks.
