Introduction

Attacks by cybercriminals targeting national critical infrastructure are increasing at an unsettling rate. Such attacks have the potential to do severe damage by upsetting transportation networks, utilities, financial services, and other vital infrastructure. The physical and digital systems that underpin a nation's economy are known as critical infrastructure thus if they were to be disrupted, there would be serious risks to the economy and public health and safety. Establishing proper cybersecurity measures and protecting those digital systems from possible threats or cyberattacks is necessary. Both public and private sector assets are included in these essential infrastructure categories.

Nationwide alert:

Recently one of the biggest hacker organizations has warned of an upcoming cyberattack on the critical infrastructure and websites in India, causing a countrywide alert. A gang of hackers from Indonesia and Pakistan, celebrating 4,000 members, announced a planned “Cyber Party” on 11 December 2023. The event’s claimed goal is to compromise and disrupt India's digital infrastructure. They disclosed this information on their Telegram channel.

This hacker organization holds a record of launching extensive cyberattacks; in the past, it sent out a "red notice" that was intended to target 12,000 websites run by the Indian government. They have previously attacked other nations, such as Israel, Sweden, and the United States. Their reasons are varied and might include anything from assaults on certain groups to religious disagreements.

The gang has also been acclaimed for hacking into a New York City police agency, obtaining health and social media data from Israel, and exposing information from Swedish social media users. These alarming events show how urgently strong and all-encompassing cybersecurity measures are needed, not only in India but throughout the world.

Effect(s) on India

1.  Central Agencies Are Alert, Expect Health Sector Attacks: The cyberinfrastructure of the health sector has been a common target of assaults, particularly in the aftermath of the COVID-19 epidemic, which has authorities particularly concerned. Relevant ministries have received notifications from central authorities advising them to take precautions against unwanted access. The security of digital infrastructure is seriously challenged by the constantly changing panorama of cyber-attacks, according to those who are aware of the warning and threat.

2. National security concerns: Because of the interconnectedness of critical national infrastructure, a cyberattack may have an impact on national security. Attacks against defense networks, intelligence organizations health infrastructure, or military systems, for instance, might make it more difficult for the nation to respond to threats from outside.

3.    Concerns for Public Safety and Health: Cyberattacks on healthcare systems run the risk of compromising patient data, stopping medical procedures, and even endangering the general public's health. This might have potentially fatal results in urgent circumstances.

4.  Data Breach and Privacy Issues: Stealing confidential data is a common component of cybersecurity assaults. A breach of critical infrastructure systems might result in sensitive data, including personal information, being misused and accessed without authorization, raising privacy issues.

Preventive and protective measures

1.    The plan for responding to incidents: Make sure a clear incident response strategy is in place, with a focus on healthcare systems, and that it is especially designed to handle cyber-attacks on critical infrastructure.

2.  Better Tracking: Observing vital networks, systems, and data flows more closely, especially in the healthcare industry. Using cutting-edge threat detection technologies to spot odd or questionable activity.

3.   Critical System Isolation: Cutting off vital healthcare systems from the wider network to reduce the chance of attackers moving laterally.

4.   Continual Backups: Make sure that backup copies of important data and systems are kept in a safe, isolated location by regularly backing them up. In the event of a ransomware attack or data breach, this makes recovery easier.

5.    Update and patch systems: Make sure that all operating systems and apps utilized in the infrastructure of the healthcare industry are updated with the most recent security updates.

6. Protocols for Communication: In the case of a cyber-incident, establishing explicit communication mechanisms to guarantee that pertinent parties are notified as soon as possible. This covers correspondence with law enforcement, the public, and other members of the healthcare industry as needed.

Conclusion

Urgent preventative actions are essential in response to an impending cyber threat revealed by a large hacker organization that is targeting India's key infrastructure, specifically the healthcare sector. The interconnectedness of this infrastructure puts public safety, privacy, and national security in danger.

Introduction

In the digital landscape, there is a rapid advancement of technologies such as generative AI(Artificial Intelligence), deepfake, machine learning, etc. Such technologies offer convenience to users in performing several tasks and are capable of assisting individuals and business entities. Certain regulatory mechanisms are also established for the ethical and reasonable use of such advanced technologies. However, these technologies are easily accessible; hence, cyber-criminals leverage AI tools and technologies for malicious activities or for committing various cyber frauds. By such misuse of advanced technologies, new cyber threats have emerged. 

Deepfake Scams 

Deepfake is an AI-based technology. Deepfake is capable of creating realistic images or videos which in actuality are created by machine algorithms. Deepfake technology, since easily accessible, is misused by fraudsters to commit various cyber crimes or deceive and scam people through fake images or videos that look realistic. By using the Deepfake technology, cybercriminals manipulate audio and video content, which looks very realistic but, in actuality, is fake. 

Voice cloning 

To create a voice clone of anyone's, audio can be deepfaked too, which closely resembles a real one but, in actuality, is a fake voice created through deepfake technology. Recently, in Kerala, a man fell victim to an AI-based video call on WhatsApp. He received a video call from a person claiming to be his former colleague. The scammer, using AI deepfake technology, impersonated the face of his former colleague and asked for financial help of 40,000. 

Uttarakhand Police issues warning admitting the rising trend of AI-based scams

Recently, Uttarakhand police’s Special Task Force (STF) has issued a warning admitting the widespread of AI technology-based scams such as deepfake or voice cloning scams targeting innocent people. Police expressed concern that several incidents have been reported where innocent people are lured by cybercriminals. Cybercriminals exploit advanced technologies and manipulate innocent people to believe that they are talking to their close ones or friends, but in actuality, they are fake voice clones or deepfake video calls. In this way, cybercriminals ask for immediate financial help, which ultimately leads to financial losses for victims of such scams. 

Tamil Nadu Police Issues advisory on deepfake scams

To deceive people, cyber criminals misuse deepfake technologies and target them for financial gain. Recently, Tamilnadu Police Cyberwing have issued an advisory on rising deepfake scams. Fraudsters are creating highly convincing images, videos or voice clones to defraud innocent people and make them victims of financial fraud. The advisory states that you limit the personal data you share you share online and adjust privacy settings. Advisory says to promptly report any suspicious activity or cyber crimes to 1930 or the National Cyber Crime Reporting portal.

Best practices 

1. Pay attention if you notice compromised video quality because deepfake videos often have compromised or poor video quality and unusual blur resolution, which poses a question to its genuineness. Deepfake videos often loop or unusually freeze, which indicates that the video content might be fabricated.

1. Whenever you receive requests for any immediate financial help, act responsively and verify the situation by directly contacting the person on his primary contact number.
2. You need to be vigilant and cautious, since scammers often possess a sense of urgency, leading to giving no time for the victim to think about it and deceiving them by making a quick decision. Scammers pose sudden emergencies and demand financial support on an urgent basis. 
3. Be aware of the recent scams and follow the best practices to stay protected from rising cyber frauds. 
4. Verify the identity of unknown callers.
5. Utilise privacy settings on your social media.
6. Pay attention if you notice any suspicious nature, and avoid sharing voice notes with unknown users because scammers might use them as voice samples and create your voice clone. 
7. If you fall victim to such frauds, one powerful resource available is the National Cyber Crime Reporting Portal (www.cybercrime.gov.in) and the 1930 toll-free helpline number where you can report cyber fraud, including any financial crimes.

Overview:

It is worth stating that millions of Windows users around the world are facing the Blue Screen of Death (BSOD) problem that makes systems shutdown or restart. This has been attributed to a CrowdStrike update that was released recently and has impacted many organizations, financial institutions, and government agencies across the globe. Indian airlines have also reported disruptions on X (formerly Twitter), informing passengers about the issue.

Understanding Blue Screen of Death:

Blue Screen errors, also known as black screen errors or STOP code errors, can occur due to critical issues forcing Windows to shut down or restart. You may encounter messages like "Windows has been shut down to prevent damage to your computer." These errors can be caused by hardware or software problems.

Impact on Industries

Some of the large U. S. airlines such as American Airlines, Delta Airlines, and United Airlines had to issue ground stops because of communication problems. Also, several airports on Friday suffered a massive technical issue in check-in kiosks for IndiGo, Akasa Air, SpiceJet, and Air India Express.

The Widespread Issue

The issue seems widespread and is causing disruption across the board as Windows PCs are deployed at workplaces and other public entities like airlines, banks, and even media companies. It has been pointed out that Windows PCs use a special cybersecurity solution from a company called CrowdStrike that seems to be the culprit for this outage, affecting most Windows PC users out there.

Microsoft's Response

The issue was acknowledged by Microsoft and the mitigations are underway. The company in its verified X handle Microsoft 365 status has shared a series information on the latest outage and they are looking into the matter. The issue is under investigation.

In one of the posts from Microsoft Azure, it is mentioned that they have become aware of an issue affecting Virtual Machines (VMs) running Windows Client and Windows Server with the CrowdStrike Falcon agent installed. These VMs may encounter a bug check (BSOD) and become stuck in a restarting state. Their analysis indicates that this issue started approximately at 19:00 UTC on July 18th. They have provided recommendations as follows:

Restore from Backup:   In case customers have available backups prior to 19:00 UTC on July 18th, they should recover VM data from the backups. If the customer is using Azure Backup, they can get exact steps on how to restore VM data in the Azure portal. here.

Offline OS Disk Repair: Alternatively, customers can attempt offline repair of the OS disk by attaching an unmanaged disk to the affected VM. Encrypted disks may require additional steps to unlock before repair. Once attached, delete the following file:

Windows/System/System32/Drivers/CrowdStrike/C00000291*.sys 

After deletion, reattach the disk to the original VM.

Microsoft Azure is actively investigating additional mitigation options for affected customers. We will provide updates as we gather more information.
