E-Commerce Brushing Scam: Alerts and Insights

Introduction

Devices and interconnectivity are the pipelines which drive the data into cyberspace, and in turn, the users consume this data to perform different tasks in the digital age. The security of devices and networks is essential as they are the first defenders of cyberspace. Bad actors often target systems and networks with malware and ransomware, these attacks are differently motivated, but all wreak havoc upon the system and can impact individuals and organisations alike. Mobile users worldwide prefer iOS or Android, but both operating systems are vulnerable to cyberattacks these days. Some of these attacks go undetected for a long time.

Op Triangulation

As reported by Kaspersky, While monitoring the network traffic of their own corporate Wi-Fi network dedicated to mobile devices using the Kaspersky Unified Monitoring and Analysis Platform (KUMA), Kaspersky noticed suspicious activity that originated from several iOS-based phones. Since it is impossible to inspect modern iOS devices from the inside, they created offline backups of the devices in question, inspected them using the Mobile Verification Toolkit’s mvt-ios and discovered traces of compromise. This is known as Operation Triangulation and has been in action since 2019 and got detected in 2023.

The Malware

A portion of the filesystem, including some of the user data and service databases, is included in mobile device backups. The files, directories, and database entries’ timestamps make it possible to reconstruct the events that happened to the device roughly. The “timeline.csv” file created by the mvt-ios software contains a sorted timeline of events that is comparable to the super-timeline utilised by traditional digital forensic tools. Pinpointing particular artefacts that show the compromise using this timeframe. This made it possible to advance the research and reassemble the broad infection sequence:

Through the iMessage service, a message with an attachment containing an exploit is delivered to the target iOS device.

The message initiates a vulnerability that results in code execution without any user input.

The exploit’s code downloads multiple additional stages, including additional exploits for privilege escalation, from the C&C server.

After successful exploitation, a fully functional APT platform is downloaded as the final payload from the C&C server.

The first message and the attachment’s exploit are removed

The lack of persistence support in the harmful toolset is most likely a result of OS restrictions. Multiple devices’ timeframes suggest that after rebooting, they might get infected again. The earliest signs of infection that we found date to 2019. The most recent version of the devices that have been successfully attacked as of the time of writing in June 2023 is iOS 15.7.

The final payload analysis is still ongoing. The programme executes with root rights, implements a set of commands for gathering user and system data, and can run any code downloaded as plugin modules from the C&C server.

Malicious Domains

Using the forensic artefacts, it was possible to identify the domain name set used by the exploits and further malicious stages. They can be used to check the DNS logs for historical information and to identify the devices currently running the malware:

Safeguards for iOS users

Despite its world-class safety and privacy architecture, iOS is vulnerable to a few attacks; the following steps can be undertaken to safeguard iOS users –

Keeping Device updated

Security patches

Disabling iMessage would prevent Zero clicks exploits or the Triangulation attacks

Paying zero attention to unwanted, unsolicited messages

The user should make sure that any application they are downloading or installing; it should be from a trusted source ( This Zero click attack does not occur by any other means, It exploits / it targets software vulnerabilities in operating systems networks and applications)

Being cautious with the messaging app and emails

Implement device restrictions (management features like parental control and restrictions over using necessary applications)

Conclusion

Operation Triangulation is one of the recent operations combating cyber attacks, but such operations are launched nearly daily. This is also due to a rapid rise in internet and technology penetration across the world. Cyberattacks have taken a new face as they have evolved with the new and emerging technology. The influence of the Darknet has allowed many hackers to remain on the black hat side due to easy accessibility to illegal tools and material over the dark net, which facilitates such crimes.

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

All citizens are using tech to their advantage, and so we see a lot of upskilling among the population leading to innovation in India. As we go deeper into cyberspace, we must maintain our cyber security efficiently and effectively. When bad actors use technology to their advantage, we often see data loss or financial loss of the victim, In this blog, we will shine light upon two new forms of cyber attacks, causing havoc upon the innocent. The “Daam” Malware and a new malicious app are the two new issues.

Daam Botnet

Since 2021, the DAAM Android botnet has been used to acquire unauthorised access to targeted devices. Cybercriminals use it to carry out different destructive actions. Using the DAAM Android botnet’s APK binding service, threat actors can combine malicious code with a legitimate application. Keylogging, ransomware, VOIP call records, runtime code execution, browser history collecting, incoming call recording, PII data theft, phishing URL opening, photo capture, clipboard data theft, WiFi and data status switching, and browser history gathering are just a few of the functions offered by the DAAM Android botnet. The DAAM botnet tracks user activity using the Accessibility Service and stores keystrokes it has recorded together with the name of the programme package in a database. It also contains a ransomware module that encrypts and decrypts data on the infected device using the AES method.

Additionally, the botnet uses the Accessibility service to monitor the VOIP call-making features of social media apps like WhatsApp, Skype, Telegram, and others. When a user engages with these elements, the virus begins audio recording.

The Malware

CERT-IN, the central nodal institution that reacts to computer security-related issues, claims that Daam connects with various Android APK files to access a phone. The files on the phone are encrypted using the AES encryption technique, and it is distributed through third-party websites.

It is claimed that the malware can damage call recordings and contacts, gain access to the camera, change passwords, take screenshots, steal SMS, download/upload files, and perform a variety of other things.

Safeguards and Guidelines by Cert-In

Cert-In has released the guideline for combating malware. These were issued in the public interest. The recommendations by Cert-In are as follows-

Only download from official app stores to limit the risk of potentially harmful apps.

Before downloading an app, always read the details and user reviews; likewise, always give permissions that are related to the program’s purpose.

Install Android updates solely from Android device vendors as they become available.

Avoid visiting untrustworthy websites or clicking on untrustworthy

Install and keep anti-virus and anti-spyware software up to date.

Be cautious if you see mobile numbers that appear to be something other than genuine/regular mobile numbers.

Conduct sufficient investigation Before clicking on a link supplied in a communication.

Only click on URLs that clearly display the website domain; avoid abbreviated URLs, particularly those employing bit.ly and tinyurl.

Use secure browsing technologies and filtering tools in antivirus, firewall, and filtering services.

Before providing sensitive information, look for authentic encryption certificates by looking for the green lock in your browser’s URL information, look for authentic encryption certificates by looking for the green lock in your browser’s URL bar.

Any ‘strange’ activity in a user’s bank account must be reported immediately to the appropriate bank.

‍

New Malicious App

From the remote parts of Jharkhand, a new form of malicious application has been circulated among people on the pretext of a bank account closure. The bad actors have always used messaging platforms like Whatsapp and Telegram to circulate malicious links among unaware and uneducated people to dupe them of their hard-earned money.

They send an ordinary-looking message on Whatsapp or Telegram where they mention that the user has a bank account at ICICI bank and, due to irregularity with the credentials, their account is being deactivated. Further, they ask users to update their PAN card to reactivate their account by uploading the PAN card on an application. This app, in turn, is a malicious app that downloads all the user’s personal credentials and shares them with the bad actors via text message, allowing them to bypass banks’ two-factor authentication and drain the money from their accounts. The Jharkhand Police Cyber Cells have registered numerous FIRs pertaining to this type of cybercrime and are conducting full-scale investigations to apprehend the criminals.

Conclusion

Malware and phishing attacks have gained momentum in the previous years and have become a major contributor to the tally of cybercrimes in the country. DaaM malware is one of the examples brought into light due to the timely action by Cert-In, but still, a lot of such malware are deployed by bad actors, and we as netizens need to use our best practices to keep such criminals at bay. Phishing crimes are often substantiated by exploiting vulnerabilities and social engineering. Thus working towards a rise in awareness is the need of the hour to safeguard the population by and large.
