#FactCheck - False Claim about Video of Sadhu Lying in Fire at Mahakumbh 2025

Executive Summary:

In late 2024 an Indian healthcare provider experienced a severe cybersecurity attack that demonstrated how powerful AI ransomware is. This blog discusses the background to the attack, how it took place and the effects it caused (both medical and financial), how organisations reacted, and the final result of it all, stressing on possible dangers in the healthcare industry with a lack of sufficiently adequate cybersecurity measures in place. The incident also interrupted the normal functioning of business and explained the possible economic and image losses from cyber threats. Other technical results of the study also provide more evidence and analysis of the advanced AI malware and best practices for defending against them. 

1. Introduction

The integration of artificial intelligence (AI) in cybersecurity has revolutionised both defence mechanisms and the strategies employed by cybercriminals. AI-powered attacks, particularly ransomware, have become increasingly sophisticated, posing significant threats to various sectors, including healthcare. This report delves into a case study of an AI-powered ransomware attack on a prominent Indian healthcare provider in 2024, analysing the attack's execution, impact, and the subsequent response, along with key technical findings.

2. Background 

 In late 2024, a leading healthcare organisation in India which is involved in the research and development of AI techniques fell prey to a ransomware attack that was AI driven to get the most out of it. With many businesses today relying on data especially in the healthcare industry that requires real-time operations, health care has become the favourite of cyber criminals. AI aided attackers were able to cause far more detailed and damaging attack that severely affected the operation of the provider whilst jeopardising the safety of the patient information.  

 3. Attack Execution 

The attack began with the launch of a phishing email designed to target a hospital administrator. They received an email with an infected attachment which when clicked in some cases injected the AI enabled ransomware into the hospitals network. AI incorporated ransomware was not as blasé as traditional ransomware, which sends copies to anyone, this studied the hospital’s IT network. First, it focused and targeted important systems which involved implementation of encryption such as the electronic health records and the billing departments. 

The fact that the malware had an AI feature allowed it to learn and adjust its way of propagation in the network, and prioritise the encryption of most valuable data. This accuracy did not only increase the possibility of the potential ransom demand but also it allowed reducing the risks of the possibility of early discovery. 

 4. Impact 

•  The consequences of the attack were immediate and severe: The consequences of the attack were immediate and severe.
•  Operational Disruption: The centralization of important systems made the hospital cease its functionality through the acts of encrypting the respective components. Operations such as surgeries, routine medical procedures and admitting of patients were slowed or in some cases referred to other hospitals. 
•  Data Security: Electronic patient records and associated billing data became off-limit because of the vulnerability of patient confidentiality. The danger of data loss was on the verge of becoming permanent, much to the concern of both the healthcare provider and its patients. 
•  Financial Loss: The attackers asked for 100 crore Indian rupees (approximately 12 USD million) for the decryption key. Despite the hospital not paying for it, there were certain losses that include the operational loss due to the server being down, loss incurred by the patients who were affected in one way or the other, loss incurred in responding to such an incident and the loss due to bad reputation. 

5. Response

As soon as the hotel’s management was informed about the presence of ransomware, its IT department joined forces with cybersecurity professionals and local police. The team decided not to pay the ransom and instead recover the systems from backup. Despite the fact that this was an ethically and strategically correct decision, it was not without some challenges. Reconstruction was gradual, and certain elements of the patients’ records were permanently erased. 

 In order to avoid such attacks in the future, the healthcare provider put into force several organisational and technical actions such as network isolation and increase of cybersecurity measures. Even so, the attack revealed serious breaches in the provider’s IT systems security measures and protocols. 

6. Outcome

The attack had far-reaching consequences:

• Financial Impact: A healthcare provider suffers a lot of crashes in its reckoning due to substantial service disruption as well as bolstering cybersecurity and compensating patients. 
•  Reputational Damage: The leakage of the data had a potential of causing a complete loss of confidence from patients and the public this affecting the reputation of the provider. This, of course, had an effect on patient care, and ultimately resulted in long-term effects on revenue as patients were retained. 
•  Industry Awareness: The breakthrough fed discussions across the country on how to improve cybersecurity provisions in the healthcare industry. It woke up the other care providers to review and improve their cyber defence status. 

7. Technical Findings

The AI-powered ransomware attack on the healthcare provider revealed several technical vulnerabilities and provided insights into the sophisticated mechanisms employed by the attackers. These findings highlight the evolving threat landscape and the importance of advanced cybersecurity measures.

7.1 Phishing Vector and Initial Penetration

• Sophisticated Phishing Tactics: The phishing email was crafted with precision, utilising AI to mimic the communication style of trusted contacts within the organisation. The email bypassed standard email filters, indicating a high level of customization and adaptation, likely due to AI-driven analysis of previous successful phishing attempts.
• Exploitation of Human Error: The phishing email targeted an administrative user with access to critical systems, exploiting the lack of stringent access controls and user awareness. The successful penetration into the network highlighted the need for multi-factor authentication (MFA) and continuous training on identifying phishing attempts.

7.2 AI-Driven Malware Behavior

• Dynamic Network Mapping: Once inside the network, the AI-powered malware executed a sophisticated mapping of the hospital's IT infrastructure. Using machine learning algorithms, the malware identified the most critical systems—such as Electronic Health Records (EHR) and the billing system—prioritising them for encryption. This dynamic mapping capability allowed the malware to maximise damage while minimising its footprint, delaying detection.
• Adaptive Encryption Techniques: The malware employed adaptive encryption techniques, adjusting its encryption strategy based on the system's response. For instance, if it detected attempts to isolate the network or initiate backup protocols, it accelerated the encryption process or targeted backup systems directly, demonstrating an ability to anticipate and counteract defensive measures.
• Evasive Tactics: The ransomware utilised advanced evasion tactics, such as polymorphic code and anti-forensic features, to avoid detection by traditional antivirus software and security monitoring tools. The AI component allowed the malware to alter its code and behaviour in real time, making signature-based detection methods ineffective.

7.3 Vulnerability Exploitation

• Weaknesses in Network Segmentation: The hospital’s network was insufficiently segmented, allowing the ransomware to spread rapidly across various departments. The malware exploited this lack of segmentation to access critical systems that should have been isolated from each other, indicating the need for stronger network architecture and micro-segmentation.
• Inadequate Patch Management: The attackers exploited unpatched vulnerabilities in the hospital’s IT infrastructure, particularly within outdated software used for managing patient records and billing. The failure to apply timely patches allowed the ransomware to penetrate and escalate privileges within the network, underlining the importance of rigorous patch management policies.

7.4 Data Recovery and Backup Failures

• Inaccessible Backups: The malware specifically targeted backup servers, encrypting them alongside primary systems. This revealed weaknesses in the backup strategy, including the lack of offline or immutable backups that could have been used for recovery. The healthcare provider’s reliance on connected backups left them vulnerable to such targeted attacks.
• Slow Recovery Process: The restoration of systems from backups was hindered by the sheer volume of encrypted data and the complexity of the hospital’s IT environment. The investigation found that the backups were not regularly tested for integrity and completeness, resulting in partial data loss and extended downtime during recovery.

7.5 Incident Response and Containment

• Delayed Detection and Response: The initial response was delayed due to the sophisticated nature of the attack, with traditional security measures failing to identify the ransomware until significant damage had occurred. The AI-powered malware’s ability to adapt and camouflage its activities contributed to this delay, highlighting the need for AI-enhanced detection and response tools.
• Forensic Analysis Challenges: The anti-forensic capabilities of the malware, including log wiping and data obfuscation, complicated the post-incident forensic analysis. Investigators had to rely on advanced techniques, such as memory forensics and machine learning-based anomaly detection, to trace the malware’s activities and identify the attack vector.

8. Recommendations Based on Technical Findings

To prevent similar incidents, the following measures are recommended:

1. AI-Powered Threat Detection: Implement AI-driven threat detection systems capable of identifying and responding to AI-powered attacks in real time. These systems should include behavioural analysis, anomaly detection, and machine learning models trained on diverse datasets.
2. Enhanced Backup Strategies: Develop a more resilient backup strategy that includes offline, air-gapped, or immutable backups. Regularly test backup systems to ensure they can be restored quickly and effectively in the event of a ransomware attack.
3. Strengthened Network Segmentation: Re-architect the network with robust segmentation and micro-segmentation to limit the spread of malware. Critical systems should be isolated, and access should be tightly controlled and monitored.
4. Regular Vulnerability Assessments: Conduct frequent vulnerability assessments and patch management audits to ensure all systems are up to date. Implement automated patch management tools where possible to reduce the window of exposure to known vulnerabilities.
5. Advanced Phishing Defences: Deploy AI-powered anti-phishing tools that can detect and block sophisticated phishing attempts. Train staff regularly on the latest phishing tactics, including how to recognize AI-generated phishing emails.

9. Conclusion

The AI empowered ransomware attack on the Indian healthcare provider in 2024 makes it clear that the threat of advanced cyber attacks has grown in the healthcare facilities. Sophisticated technical brief outlines the steps used by hackers hence underlining the importance of ongoing active and strong security. This event is a stark message to all about the importance of not only remaining alert and implementing strong investments in cybersecurity but also embarking on the formulation of measures on how best to counter such incidents with limited harm. AI is now being used by cybercriminals to increase the effectiveness of the attacks they make and it is now high time all healthcare organisations ensure that their crucial systems and data are well protected from such attacks.

Introduction

Misinformation is rampant all over the world and impacting people at large. In 2023, UNESCO commissioned a survey on the impact of Fake News which was conducted by IPSOS. This survey was conducted in 16 countries that are to hold national elections in 2024 with a total of 2.5 billion voters and showed how pressing the need for effective regulation had become and found that 85% of people are apprehensive about the repercussions of online disinformation or misinformation. UNESCO has introduced a plan to regulate social media platforms in light of these worries, as they have become major sources of misinformation and hate speech online. This action plan is supported by the worldwide opinion survey, highlighting the urgent need for strong actions. The action plan outlines the fundamental principles that must be respected and concrete measures to be implemented by all stakeholders associated, i.e., government, regulators, civil society and the platforms themselves. 

The Key Areas in Focus of the Action Plan

The focus area of the action plan is on the protection of the Freedom of Expression while also including access to information and other human rights in digital platform governance. The action plan works on the basic premise that the impact on human rights becomes the compass for all decision-making, at every stage and by every stakeholder. Groups of independent regulators work in close coordination as part of a wider network, to prevent digital companies from taking advantage of disparities between national regulations. Moderation of content as a feasible and effective option at the required scale, in all regions and all languages. 

The algorithms of these online platforms, particularly the social media platforms are established, but it is too often geared towards maximizing engagement rather than the reliability of information. Platforms are required to take on more initiative to educate and train users to be critical thinkers and not just hopers. Regulators and platforms are in a position to take strong measures during particularly sensitive conditions ranging from elections to crises, particularly the information overload that is taking place.

Key Principles of the Action Plan

1. Human Rights Due Diligence: Platforms are required to assess their impact on human rights, including gender and cultural dimensions, and to implement risk mitigation measures. This would ensure that the platforms are responsible for educating users about their rights.
2. Adherence to International Human Rights Standards: Platforms must align their design, content moderation, and curation with international human rights standards. This includes ensuring non-discrimination, supporting cultural diversity, and protecting human moderators.
3. Transparency and Openness: Platforms are expected to operate transparently, with clear, understandable, and auditable policies. This includes being open about the tools and algorithms used for content moderation and the results they produce.
4. User Access to Information: Platforms should provide accessible information that enables users to make informed decisions. 
5. Accountability: Platforms must be accountable to their stakeholders which would include the users and the public, which would ensure that redressal for content-related decisions is not compromised. This accountability extends to the implementation of their terms of service and content policies.

Enabling Environment for the application of the UNESCO Plan

The UNESCO Action Plan to counter misinformation has been created to create an environment where freedom of expression and access to information flourish, all while ensuring safety and security for digital platform users and non-users. This endeavour calls for collective action—societies as a whole must work together. Relevant stakeholders, from vulnerable groups to journalists and artists, enable the right to expression. 

Conclusion

The UNESCO Action Plan is a response to the dilemma that has been created due to the information overload, particularly, because the distinction between information and misinformation has been so clouded. The IPSOS survey has revealed the need for an urgency to address these challenges in the users who fear the repercussions of misinformation. 

The UNESCO action plan provides a comprehensive framework that emphasises the protection of human rights, particularly freedom of expression, while also emphasizing the importance of transparency, accountability, and education in the governance of digital platforms as a priority. By advocating for independent regulators and encouraging platforms to align with international human rights standards, UNESCO is setting the stage for a more responsible and ethical digital ecosystem. 

The recommendations include integrating regulators through collaborations and promoting global cooperation to harmonize regulations, expanding the Digital Literacy campaign to educate users about misinformation risks and online rights, ensuring inclusive access to diverse content in multiple languages and contexts, and monitoring and refining tech advancements and regulatory strategies as challenges evolve. To ultimately promote a true online information landscape.

Introduction

Digital Arrests are a form of scam that involves the digital restraint of individuals. These restraints can vary from restricting access to the account(s), and digital platforms, to implementing measures to prevent further digital activities or being restrained on video calling or being monitored through video calling. Typically, these scams target vulnerable individuals who are unfamiliar with digital fraud tactics, making them more susceptible to manipulation. These scams often target the victims on allegations of drug trafficking, money laundering, falsified documents, etc. These are serious crimes and these scammers scare the victim into thinking that either their identities were used to commit these crimes or they have committed these crimes. Recently there has been an uptick in the digital fraud scams in India highlighting the growing concerns.

The Legality of Digital Arrests in India

There is no legal provision for law enforcement to conduct ‘arrests’ via video calls or online monitoring. If you receive such calls, it is a clear scam. In fact, recently enacted new criminal laws do not provide for any provision for law enforcement agencies conducting a digital arrest.  The law only provides for service of the summons and the proceedings in an electronic mode. 

The Bhartiya Nagrik Suraksha Sanhita (BNSS), 2023 provides for the summons to be served electronically under section 63. The section defines the form of summons. It states that every summons served electronically shall be encrypted and bear the image of the seal of the Court or digital signature. Further, according to section 532 of the BNSS, the trial and proceedings may be held in electronic mode, by use of electronic communication or by the use of audio-video electronic means. 

Modus Operandi

Under digital arrest scams, the scammer makes a connection via video calls (WhatsApp calls, skype, etc) with the victim over their alleged involvement in crimes (financial, drug trafficking, etc) in bogus charges. The victims are intimidated that the arrest will take place soon and till the time the arresting officers do not reach the victim they are to remain on the call and be under digital surveillance and not contact anyone during the ongoing investigation. 

During this period, the scammers start collecting information from the victim to confirm their identity and create an atmosphere in which multiple senior officials are on the victim’s case and they are investigating the case thoroughly. By this time, the victim, scared out of their wits, sits through this arrest and it is then that the scammers posing as law enforcement officials make comments that they can avoid arrest by paying a certain amount of the fines to the accounts that they specify.  This monitoring/ surveillance continues till the time the victim makes the transfers to the accounts provided by the scammers. These are the common manipulation tactics used by scammers in digital arrest fraud.

Recent Cyber Arrest Cases

• Recently a 35-year-old NBCC official was duped of Rs 55 lakh in a 'digital arrest' scam. Posing as customs officials, fraudsters claimed her details were linked to intercepted illegal items and a pending arrest. They kept her on video calls, convincing her to transfer Rs 55 lakh to avoid money laundering charges. After the transfer, the scammers vanished. A police investigation traced the funds to a fake company, leading to the arrest of suspects.
• Another recent case involved a neurologist who was duped Rs 2.81 crores in a ‘digital arrest’ scam. Fraudsters claimed her phone number and Aadhaar was linked to accounts transferring funds to an Individual. Under pressure, she was convinced to undergo “verification” and made multiple transactions over two days. The scammers threatened legal consequences for money laundering if she didn’t comply. Now a police investigation is ongoing, and her immense financial loss highlights the severity of this cybercrime.
• One another case took place where the victim was duped of Rs 7.67 crores in a prolonged ‘digital arrest’ scam over three months. Fraudsters posing as TRAI officials claimed complaints against her phone number and threatened to suspend it, alleging illegal use of another number linked to her Aadhaar. Pressured and manipulated through video calls, the victim was coerced into transferring large sums, even taking an Rs 80 lakh loan. The case is under investigation as authorities pursue the cybercriminals behind the massive fraud.

Best Practices

• Do not panic when you get any calls where sudden unexpected news is shared with you. Scammers thrive on the panic that they create.
• Do not share personal details such as Aadhaar number, PAN number etc with unknown or suspect entities. Be cautious of your personal and financial information such as credit card numbers, OTPs, or any other passwords with anyone.
• If individuals contact, claiming to be government officials, always verify their identities by contacting the entity through the proper channels. 
• Report and block any fraudulent communications that are received and mark them as Spam. This would further inform other users if they see the caller ID being marked as fraud or spam.
• If you have been defrauded then report about the same to the authorities so that action can be taken and authorities can arrest the fraudsters. 
• Do not transfer any money as part of ‘fines’ or ‘dues’ to the accounts that these calls or messages link to. 
• In case of any threat, issue or discrepancy, file a complaint at cybercrime.gov.in or helpline number 1930. You can also seek assistance from the CyberPeace helpline at +91 9570000066.
