Being aware of evolving scams

1. 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. 
2. 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. 
3. Stalkerware or spyware: Stalkware or spyware is one of the serious threats to individual digital safety and personal information. Stalkware is basically software installed into your device without your consent or knowledge in order to track your activities and exploit your data. Stalkware, also referred to as spyware, is a type of malicious software secretly installed on your device without your knowledge. Its purpose is to track you or monitor your activities and record sensitive information such as passwords, text messages, GPS location, call history and access to your photos and videos. Cybercriminals and stalkers use this malicious software to unauthorisedly gain access to someone's phone devices.

‍

Best practices or Cyber security tips:

• Keep your software up to date: Turn on automatic software updates for your device and make sure your mobile apps are up to date.
• Using strong passwords: Use strong passwords on your lock/unlock and on important apps on your mobile device.
• Using 2FA or multi-factor authentication: Two-factor authentication or multi-factor authentication provides extra layers of security. Be cautious before clicking on any link and downloading any app or file: Users are often led to click on malicious online links. Scammers may present such links to users through false advertisements on social media platforms, payment processes for online purchases, or in phone text messages. Through the links, victims are led either to phishing sites to give away personal data or to download harmful Android Package Kit (APK) files used to distribute and install apps on Android mobile phones.‍
• Secure Payments: Do not open any malicious links. Always make payments from secure and trusted payment apps.  Use strong passwords for your payment apps as well. And secure your banking credentials.‍
• Safe browsing: Pay due care and attention while clicking on any link and downloading content. Ignore the links or attachments of suspicious emails which are from an unknown sender. ‍
• Do not download third-party apps: Using an APK file to download a third-party app to an Android device is commonly known as sideloading. Be cautious and avoid downloading apps from third-party or dubious sites. Doing so may lead to the installation of malware in the device, which in turn may result in confidential and sensitive data such as banking credentials being stolen. Always download apps only from the official app store.‍
• App permissions: Review app permission and only grant permission which is necessary to use that app. ‍
• Do not bypass security measures: Android offers more flexibility in the mobile operating system and in mobile settings. For example, sideloading of apps is disabled by default, and alerts are also in place to warn users. However, an unwitting user who may not truly understand the warnings may simply grant permission to an app to bypass the default setting.‍
• Monitoring: Regularly monitor your devices and system logs for security check-ups and for detecting any suspicious activity.‍
• Reporting online scams: A powerful resource available to victims of cybercrime is the National Cyber Crime Reporting Portal, equipped with a 24x7 helpline number, 1930. This portal serves as a centralized platform for reporting cybercrimes, including financial fraud.

Introduction

In an alarming event, one of India’s premier healthcare institutes, AIIMS Delhi, has fallen victim to a malicious cyberattack for the second time in the year. The Incident serves as a clear-cut reminder of the escalating threat landscape faced by the healthcare organisation in this digital age. In the attack, which unfolded with grave implications, the attackers not only explored the vulnerabilities present in the healthcare sector, but this also raised the concern about the security of patient data and the uninterrupted delivery of critical healthcare services. In this blog post, we will explore the incident, what happened, and what safety measures can be taken.

Backdrop

The cyber-security systems deployed in AIIMS, New Delhi, recently detected a malware attack. The nature and scope of the attack were both sophisticated and targeted. This second hack acts as a wake-up call for healthcare organisations nationwide. As the healthcare business increasingly depends on digital technology to improve patient care and operational efficiency, cybersecurity must be prioritised to protect sensitive data. To minimise cyber-attack dangers, healthcare organisations must invest in robust defences such as multi-factor authentication, network security, frequent system upgrades, and employee training.

The attempt was successfully prevented, and the deployed cyber-security systems neutralised the threat. The e-Hospital services remain to be fully secure and are functioning normally.

Impact on AIIMS

Healthcare services have been under hackers’ radar worldwide, and the healthcare sector has been impacted badly. The attack on AIIMS Delhi’s effects has been both immediate and far-reaching. The organisation, which is recognised for delivering excellent healthcare services and performing breakthrough medical research, faced significant interruptions in its everyday operations. Patient care and treatment processes were considerably impeded, resulting in delays, cancellations, and the inability to access essential medical documents. The stolen data raises serious concerns about patient privacy and confidentiality, raising doubts about the institution’s capacity to protect sensitive information. Furthermore, the financial ramifications of the assault, such as the cost of recovery, deploying more robust cybersecurity measures, and potential legal penalties and forensic analyses, contribute to the scale of the effect. The event has also generated public concerns about the institution’s ability to preserve personal information, undermining confidence and degrading AIIMS Delhi’s image.

Impact on Patients: The attacks not only impact the institutes but also have serious implications for the patients and here are some key highlights:

Healthcare Service Disruption: The hack has affected the seamless delivery of healthcare services at AIIMS Delhi. Appointments, surgeries, and other medical treatments may be delayed, cancelled, or rescheduled. This disturbance can result in longer wait times, longer treatment periods, and potential problems from delayed or interrupted therapy.

Patient Privacy and Confidentiality are jeopardised because of the breach of sensitive patient data. Medical data, test findings, and treatment plans may have been compromised. This breach may diminish patient faith in the institution’s capacity to safeguard their personal information, discouraging them from seeking care or submitting sensitive information in the future.

As a result of the cyberattack, patients may endure mental anguish and worry. Fear of possible exploitation of personal health information, confusion about the scope of the breach, and concerns about the security of their healthcare data can all have a negative impact on their mental health. This stress might aggravate pre-existing medical issues and impede total recovery.

Trust at stake: A data breach may harm patients’ faith and confidence in AIIMS Delhi and the healthcare system. Patients rely on healthcare facilities to keep their information secure and confidential while providing safe, high-quality care. A hack can doubt the institution’s ability to safeguard patient data, affecting patients’ overall faith in the organisation and potentially leading to patients seeking care elsewhere.

Cybersecurity Measures

To avoid future hacks and protect patient data, AIIMS Delhi must prioritize enhancing its cybersecurity procedures. The institution can strengthen its resistance to changing threats by establishing strong security practices. The following steps can be considered.

Using Multi-factor Authentication: By forcing users to submit several forms of identity to access systems and data, multi-factor authentication offers an extra layer of protection. AIIMS Delhi may considerably lower the danger of unauthorised access by applying this precaution, even in the case of leaked passwords or credentials. Biometrics and one-time passwords, for example, should be integrated into the institution’s authentication systems.

Improving Network Security and Firewalls: AIIMS Delhi should improve network security by implementing strong firewalls, intrusion detection and prevention systems, and network segmentation. These techniques serve to construct barriers between internal systems and external threats, reducing attackers’ lateral movement within the network. Regular network traffic monitoring and analysis can assist in recognising and mitigating any security breaches.

Risk Assessment: Regular penetration testing and vulnerability assessments are required to uncover possible flaws and vulnerabilities in AIIMS Delhi’s systems and infrastructure. Security professionals can detect vulnerabilities and offer remedial solutions by carrying out controlled simulated assaults. This proactive strategy assists in identifying and addressing any security flaws before attackers exploit them.

Educating and training Healthcare Professionals: Education and training have a crucial role in enhancing cybersecurity practices in healthcare facilities. Healthcare workers, including physicians, nurses, administrators, and support staff, must be well-informed about the importance of cybersecurity and trained in risk-mitigation best practices. This will empower healthcare professionals to actively contribute to protecting the patient’s data and maintaining the trust and confidence of patients.

Learnings from Incidents

AIIMS Delhi should embrace cyber-attacks as learning opportunities to strengthen its security posture. Following each event, a detailed post-incident study should be performed to identify areas for improvement, update security policies and procedures, and improve employee training programs. This iterative strategy contributes to the institution’s overall resilience and preparation for future cyber-attacks. AIIMS Delhi can effectively respond to cyber incidents, minimise the impact on operations, and protect patient data by establishing an effective incident response and recovery plan, implementing data backup and recovery mechanisms, conducting forensic analysis, and promoting open communication. Proactive measures, constant review, and regular revisions to incident response plans are critical for staying ahead of developing cyber threats and ensuring the institution’s resilience in the face of potential future assaults.

Conclusion

To summarise, developing robust healthcare systems in the digital era is a key challenge that healthcare organisations must prioritise. Healthcare organisations can secure patient data, assure the continuation of key services, and maintain patients’ trust and confidence by adopting comprehensive cybersecurity measures, building incident response plans, training healthcare personnel, and cultivating a security culture. Adopting a proactive and holistic strategy for cybersecurity is critical to developing a healthcare system capable of withstanding and successfully responding to digital-age problems.

Introduction

With mobile phones at the centre of our working and personal lives, the SIM card, which was once just a plain chip that links phones with networks, has turned into a vital component of our online identity, SIM cloning has become a sneaky but powerful cyber-attack, where attackers are able to subvert multi-factor authentication (MFA), intercept sensitive messages, and empty bank accounts, frequently without the victim's immediate awareness. As threat actors are becoming more sophisticated, knowing the process, effects, and prevention of SIM cloning is essential for security professionals, telecom operators, and individuals alike.

Understanding SIM Cloning

SIM cloning is the act of making an exact copy of a victim's original SIM card. After cloning, the attacker's phone acts like the victim's, receiving calls, messages, and OTPs. This allows for a variety of cybercrimes, ranging from unauthorised financial transactions to social media account hijacking. The attacker virtually impersonates the victim, often leading to disastrous outcomes.

The cloning can be executed through various means:

● Phishing or Social Engineering: The attack compels the victim or a mobile carrier into divulging personal information or requesting a replacement SIM.

● SIM Swap Requests: Attackers use fake IDs or stolen credentials to make telecom providers port the victim's number to a new SIM.

● SS7 Protocol Exploitation: Certain sophisticated attacks target weaknesses in the Signalling System No. 7 (SS7) protocol employed by cellular networks to communicate.

● Hardware based SIM Cloning: Although uncommon, experienced attackers will clone SIMs through the use of specialized hardware and malware that steals authentication keys.

The Real-World Consequences

The harm inflicted by SIM cloning is systemic as well as personal. The victims are deprived of their phones and online accounts, realising the breach only when improper dealings or login attempts have occurred. The FBI reported over $50 million loss in 2023 from crimes associated with SIM, most of which involved cryptocurrency account and high net-worth persons.

Closer to home, Indian entrepreneurs, journalists, and fintech users have reported losing access to their numbers, only to have their WhatsApp, UPI, and banking apps taken over. In a few instances, the attackers even contacted contacts, posing as the victim to scam others.

Why the Threat Is Growing

Dependence on SMS-based OTPs is still a core vulnerability. Even as there are attempts to move towards app-based two-factor authentication (2FA), most banking, government, and e-commerce websites continue to employ SMS as their main authentication method. This reliance provides an entry point for attackers who can replicate a SIM and obtain OTPs without detection.

Vulnerabilities in telecom infrastructure are also a part of the issue. Insider attacks at telecom operators, where malicious employees handle fraud SIM swap requests, also keep cropping up. On top of that, most users are not even aware of what exactly SIM cloning is or how to identify it, leaving attackers with a head start.

Very often, the victims are only aware that their SIM has been cloned when they lose mobile service or notice unusual activity on their accounts. Red flags include loss of signal, failure to send or receive messages, and inability to receive OTPs. Alerts on password changes or unusual login attempts must never be taken lightly, particularly if this is coupled with loss of mobile service.

How Users Can Protect Themselves

● Use A Strong SIM Pin: This protects your SIM from access by unauthorized users should your phone be lost or stolen.

● Secure Personal Information: Don't post sensitive personal information online that can have a place in social engineering.

● Notify your Carrier of Suspicious Activity: If your phone suddenly has lost service or is behaving strangely, contact your mobile operator immediately.

● Register for Telecom Alerts: Many providers offer alerts to SIM swap or porting requests that are useful to preliminarily detect a possible takeover.

● Verify SIM card status using Sanchar Saathi: Visit [https://sancharsaathi.gov.in](https://sancharsaathi.gov.in) to check how many mobile numbers are issued using your ID. This government portal allows you to identify unauthorized or unknown SIM cards, helping prevent SIM swapping fraud. You can also request to block suspicious numbers linked to your identity.

Conclusion

SIM cloning is not a retrograde nod to vintage cybercrime; it's an effective method of exploitation, especially where there's a strong presence of SMS-based authentication. The attack vector is simple, but the damage it causes can be profound, both financial and reputational. With telecommunication networks forming the backbone of digital identity, users, regulators, and telecom service providers have to move in tandem. For the users, awareness is the best protection. For Telecoms, security must be a baseline requirement, not a value-add option. It's time to redefine mobile security, before your identity is in anyone else's hands.
