IP 123.201.40[.]112 uses the requested URL-path to make a GET request on the IP-address at port 80. "NOT RESPONDED" is the response status code for the request "C:\PROGRAM FILES GOOGLE CHROME APPLICATION CHROME.EXE" that was started by the process. 

Programs that retrieve their server data using a GET request are considered legitimate. The Google Chrome browser, a fully functional application widely used for web browsing, was used to make the actual request. It asks to get access to the server with IP 123.201.40[.]112 in order to collect its data and other resources. 

Malware uses GET requests to retrieve more commands or to send data back to the command and control servers. In this instance, it may be an attack server making the request to a known IP address with a known port number. Since the server has not replied to the request, the response status "NOT RESPONDED" may indicate that the activity was carried out with malicious intent.

This graph illustrates how the Qakbot virus operates and interacts with its C2 server, located in India and with the IP address 123.201.40[.]112.

Introduction

Taj Hotels Group is well known for its luxurious ambience and old-world grace and charm, blended with contemporary comforts and amenities for its guests or customers. But what can make all the netizens perplexed is the recent data breach incident which took place in Tata-owned Taj hotels. The hotel suffer from a data breach that compromises nearly 1.5 million customers' data which includes addresses, membership IDs, mobile numbers and other personally identifiable information, according to sources. This news was brought to light which raised concerns about the privacy and data protection of personal data of individuals. We are living in a space influenced by advanced technology and digital communication which throws a concern or challenge to secure the personal information of individuals. 

Unveiling the incident 

Tata-owned Taj Hotels group has suffered a data breach that compromise information of over 1.5 million customers, according to a news report. A bad actor or entity going by the name “Dnacookies” claimed data set contains data from the 2014-2020 period and has not been disclosed anywhere till now. Such personal data includes name, address, customer ID, mobile number and other personally identifiable information. This shows the risks or challenges of data protection and security. The incidents raise an alarm about the risks and vulnerabilities that might be faced even by the big corporate giants. The bad actor with the handle “Dnacookies” also demanded a ransom of a sum of about Rs 4.16 lakh from the Taj hotel group. In response to the incident, a spokesperson from the concerned hotel group said that we have been made aware of someone claiming possession of a limited data customer data set, which is non-sensitive in nature. Investigation is underway and relevant authorities have been notified about the incident.

‍A demand for ransom

The report from CNBC-TV18 clears that the bad actor not only purloined the data but also demanded around 4.16 lakh as a ransom for the database.  Along with this, the bad actor kept three conditions ahead. Firstly there has to be a middleman for a negotiable deal secondly the data cannot be split either the entire data has to be taken with the ransom demand or no data at all. Thirdly additional samples of data will not be provided. Further, the spokesperson of Indian Hotel Company Limited mentioned that they have been escalated with the fact that someone is claiming authority in a limited data set. The bad actor claimed that the database contains information from 2014- 2020 which has been kept confidential till now. The audacity of the bad actor went to such an extent that the sample containing one thousand rows of unique entries from the bad actor dataset was also provided by the bad actor as proof of the deed. This incident underlines the growing threat in cyberspace and the urgency for individuals, organizations or entities to priorities data security measures and maintain cyber resilience.

Personal Data on Stake

Such data is the personal information of the individuals and also constitutes the personal tastes and preferences of individuals which can be exploited. The biggest gush of winds the hotel and individuals face by such a data breach is not only the volume of data compromised but also the potential ways it can get misused and exploited against the hotel or its customers by cyber crooks. This paves the way for cybercriminals to put forward any demand knowing the sensitivity of the data. Followed by creating a dilemmatic situation for the affected entities to either accept the ransom demands or to stand against ransom. Since the risks are high, going ahead with any of these situations can have an adverse impact on the security of personal data. The organisation or entities holding the personal data need to make sure that data under their realm is well protected and secured.

While the organisation has to sail through the aftermath of this breach, such incidents also pose a challenge for the organisation to maintain the trust and reputation of the organization since these incidents question the cyber security posture of the organisation. It is suggested to be transparent with its stakeholders, and open about the vulnerabilities and steps taken against this. They should also discuss the amplified step added for safeguarding their customer's personal data. Since Taj is well known for its out-of-the-box luxury and for providing comfort to its customers it should take a step ahead to reinforce its digital infrastructure to ensure the security of data.

Digital Personal Data Protection Act, 2023

The newly enacted Digital Personal Data Act, 2023 put certain obligations on data fiduciaries to take reasonable measures to maintain the security of personal data. The Act also requires to inform about the data breach to the data protection board constituted under the Act. The Act aims to protect the individual's digital personal data. The Act casts certain obligations on data principals and data fiduciaries. The Act provides penalty upto 250 crores in case of a data breach. The Act aims to provide consent-based data collection techniques. The Act also establishes the Data Protection Board to ensure compliance with the provisions of the Act and address grievances. 

Conclusion

Data breach in such a big giant in the market serves as an alarming concern to be more cautious and proactively take precautionary measures to protect the security of data and compliance with data protection laws and regulations. We are living in an era where digital security is as important as the basic fundamental rights of an individual. Taj Hotels Group has actively taken steps to handle the aftermath of the data breach by informing the incident to law enforcement agencies and taking necessary steps.  It is also on our part to be more aware, and vigilant about our personal data. Entities need to ensure compliance and measures to protect personal data and overall ensure a true cyber-safe & digital environment.

Starting in mid-December, 2024, a series of attacks have targeted Chrome browser extensions. A data protection company called Cyberhaven, California, fell victim to one of these attacks. Though identified in the U.S., the geographical extent and potential of the attack are yet to be determined. Assessment of these cases can help us to be better prepared for such instances if they occur in the near future. 

The Attack

Browser extensions are small software applications that add and enable functionality or a capacity (feature) to a web browser. These are written in CSS, HTML, or JavaScript and like other software, can be coded to deliver malware. Also known as plug-ins, they have access to their own set of Application Programming Interface (APIs). They can also be used to remove unwanted elements as per customisation, such as pop-up advertisements and auto-play videos, when one lands on a website. Some examples of browser extensions include Ad-blockers (for blocking ads and content filtering) and StayFocusd (which limits the time of the users on a particular website).

In the aforementioned attack, the publisher of the browser at Cyberhaven received a phishing mail from an attacker posing to be from the Google Chrome Web Store Developer Support. It mentioned that their browser policies were not compatible and encouraged the user to click on the “Go to Policy”action item,  which led the user to a page that enabled permissions for a malicious OAuth called Privacy Policy Extension (Open Authorisation is an adopted standard that is used to authorise secure access for temporary tokens). Once the permission was granted, the attacker was able to inject malicious code into the target’s Chrome browser extension and steal user access tokens and session cookies. Further investigation revealed that logins of certain AI and social media platforms were targeted.

CyberPeace Recommendations

As attacks of such range continue to occur, it is encouraged that companies and developers take active measures that would make their browser extensions less susceptible to such attacks. Google also has a few guidelines on how developers can safeguard their extensions from their end. These include:

1. Minimal Permissions For Extensions- It is encouraged that minimal permissions for extensions barring the required APIs and websites that it depends on are acquired as limiting extension privileges limits the surface area an attacker can exploit.
2. Prioritising Protection Of Developer Accounts- A security breach on this end could lead to compromising all users' data as this would allow attackers to mess with extensions via their malicious codes. A 2FA (2-factor authentication) by setting a security key is endorsed.
3. HTTPS over HTTP- HTTPS should be preferred over HTTP as it requires a Secure Sockets Layer (SSL)/ transport layer security(TLS) certificate from an independent certificate authority (CA). This creates an encrypted connection between the server and the web browser.

Lastly, as was done in the case of the attack at Cyberhaven, it is encouraged to promote the practice of transparency when such incidents take place to better deal with them.
